Now both urban sewage pipe sewage also have industrial wastewater, domestic sewage, industrial effluent mixed up this is the wrong approach,UGG boots, for the natural ecology to build sewage treatment system, to achieve zero emissions.
human life sewage generated the vast majority of non-toxic organic wastewater, which is mainly organic pollutants, and its gift of nature from a variety of human food, it should return to nature; domestic sewage on human is water, is contamination, it is a valuable plant for the organic fertilizer; The correct way is: the use of the natural flora in the soil to break down organic matter in sewage, the use of natural soil filtration and purification of sewage, the use of trees to absorb water of organic matter, inorganic and water to achieve ecological sewage treatment, waste to treasure, zero discharge of sewage; We appreciate the pit of ecological civilization, but also distributing latrines smell, breeding of mosquitoes and other shortcomings, should be in accordance with the good water purifier,UGG boots clearance, , who control, so that urban sewage dismembered.
b. allow full access to sewage and soil from the earth's natural bacteria break down organic matter.
c. large trees and other methods using high density soil decomposition of organic matter absorbed and used to build green forest city.
d. of natural soil absorption sewage purification, groundwater recharge, to achieve zero emissions.
e. transpiration by trees to purify the sewage, regulation of air humidity, so that water back to nature.
f. situ rainwater harvesting this valuable, free fresh water resources.
6.1 front of the building after the construction of large-capacity cesspool
modern eco-concrete building with a small sealed septic tanks, is produced by modern urban life, a major source of pollution, should make full use of front of building After the green open space, according to the population of building sewage, soil seepage capacity, evaporation plant, the use of hollow bricks and other environmentally friendly building materials, eco-building large-capacity cesspool:
a. the bottom and around the sewage pool hollow brick building, so that full contact with soil and water sewage tank top
b. sealed with concrete, anti-mosquito, anti-odor.
c. the volume of sewage tank should be large enough to ensure zero discharge of wastewater non-rainy season.
d. cesspool good water around planted trees to absorb organic matter in sewage, water and achieve water-free, fat-free green.
e. Construction of seepage-type biogas digesters can explore other energy saving applications.
6.2 Construction of seepage water collection pool
type of concrete to harden around the city so that rainwater can not infiltrate into the ground, can only be discharged along the outfall of urban cities also increased temperature, drought, water shortage, so that rain that the loss of precious fresh water resources in vain, should take full advantage of this valuable supplement the groundwater resources of fresh water in each block surrounding the use of hollow bricks, blocks and other construction waste materials, building rainwater collection tanks, road construction along the water type, water seepage type drains, which would set small water for the flood, effective complement urban groundwater to ease the water shortage situation in the city, green city for the construction of free water.
6.3 community building, multi-functional eco-ditch
streets now use rainwater sewage, sewage outfall are confined concrete way, is also the maker of environmental pollution, should build multi seepage features integrated ecological sewage ditch. Along the residential street sidewalk hollow brick, stone, building materials and other environmental protection high-capacity wide-body type of underground water seepage ditch their ecological functions:
a. carrying a small amount of ecological cesspool not fully absorb excess domestic sewage, continue to waste water treatment
b. ecological drainage for rainwater to collect rainwater into the ground during the dry season to supplement the groundwater.
c. with a huge amount of rain during the rainy season automatically clean the sewage ditch, the increase in urban groundwater.
d. trees on both sides of the street to provide water, organic fertilizer, green-free water to achieve fat-free.
e. as electricity, telecommunications, broadcasting, water supply, heating and other compensation for installation of underground pipes to provide space for city streets suffering from multiple cut open and save huge human material and financial resources to increase revenue for the city .
so we built up to a sewage tank as the main ecological, ecological sewage ditch the auxiliary zero-emission eco-city sewage system; in the rainy season, although there will be a small amount of domestic sewage into the river with the huge amount of rain, but not cause environmental pollution, in line with the natural ecological laws and the requirements of the food chain; natural waters provide fish for us human beings and other lush crab turtle food aid, food chain, humans are the top level of the earth, we should give back to nature what ---- amount of organic matter in sewage, the main food chain is as follows: appropriate amount of organic matter in the water sewage fungus, algae, aquatic plants, plankton, small fish, shrimp big fish man amount of sewage organic matter.
7. Construction of municipal solid waste ecological treatment system:
now the main municipal solid waste treatment: landfilling, soil organic matter --- so excessive, smelly black soil and waste land resources, damage to buried in the natural environment; burning - create dioxins and other air pollution, should be based on processing mode, environmentally friendly methods of garbage in the trees should be green, desert control,cheap UGG boots, desert sand control, agriculture and other applications.
7.1 garbage processing mode of the ecological:
garbage into garbage smell is due to excessive moisture, high temperature causes massive spoilage bacteria breeding in the garbage, decomposing organic matter in curing hydrogen, ammonia, the formation of odor; control the stench of garbage in two ways:
7.1.1 local press, dismembered
massive waste of spoilage bacteria reproducible stench need to meet three conditions: water + oxygen + high temperature, the nature of the temperature is beyond our control, but we can squeeze through a dedicated machine on the way junk removal garbage in the water, crushing the garbage after the garbage blocks to form a hard cut off from contact with oxygen garbage, refuse no water, no oxygen spoilage lost breeding conditions to solve the odor problem of garbage generated.
our living quarters, the unit set up garbage crushing machine, crushing into the large capacity of the sewage generated ecological wastewater pond area of green trees nourished; block the production of garbage does not stink, they can accumulate in water storage does not harm the environment that municipal waste piecemeal; garbage block decomposition of organic matter can be converted by anaerobic fermentation of bio-organic fertilizer; hard block easy to transport garbage, refuse transportation cost savings; may land area of trees buried in the soil for the next Tree dressing; also be used for desert control long-distance transport.
7.1.2 focus on nature and environmental protection under the concept of
to achieve the purpose of deodorant; such as the photosynthetic bacteria as the main group of beneficial microorganisms to absorb hydrogen sulfide, ammonia and other deodorant effect, and can inhibit the reproduction of spoilage bacteria and achieve eco-deodorant, anti-bacterial ecology. Accordingly stinking garbage that had corruption can be beneficial microorganism bacterium sprayed on the garbage deodorizing, sterilizing, inhibition of the organic waste and corruption; treatment 1: stacking sealed fermentation production of biological organic fertilizer; Method 2: Use machinery to press to the water, pressed into a thin square or circular block, and then used for afforestation, desertification control, desert sand and other organic matter where necessary, make the city garbage split up, the best use:
a. planting greening, tree fertilizer, garbage in the thin tree cover around the block, then covered with soil, trees and water make drought, slow decomposition of waste in the soil to provide nutrients for the trees, turning waste into treasure.
b. Governance for the desert, desert soil water deficit, the lack of organic matter, in the desert is covered with a thin block spam, the desert sand for water, increase soil organic matter the desert, and ultimately achieving the purpose of the deserts.
c. for the hills, hills and other marginal land afforestation and so on.
8. build zero emissions of industrial waste water treatment system
for eco-industrial sewage waste, whether organic or non-toxic chemical toxic waste should be strictly in accordance with who will come to the sewage treatment, sewage not factory / area, the principle of zero-emission comprehensive;
We analyzed many of the people most affected heavy metal contamination, heavy metal river pollution, pollution of the groundwater, where water is the main carrier of pollutants, That is the role of water on the spread of pollutants is the main cause, so its pollution prevention and control of industrial wastewater seepage, anti-sewer overflows treatment is the key.
long as there is human life and production activities will have pollution exists, we can only choose to pollution, pollution of local processing only a small area, not able to magnify pollution caused by large rivers and lakes polluted, that the expense of keep the environment small environment. Constructed of concrete pipe drainage system so that sewage from factories in convenient, cost zero discharge plant, set small for large sewage pollution, pollution of the environment, all plants should be cut off the sewage outlet, according to the degree and type of water damage, can be recycled use of recycling, can not be recycled locally impermeable storage, will be the responsibility of sewage effluent returned to the manufacturer, so that polluters take the initiative to control pollution.
the classification of many industrial effluents from wastewater treatment and waste water dangers Difficult starting, the main pollutants in wastewater can be divided into three categories: first category is the waste heat, mainly from the cooling water , cooling water can be reused; the second category of conventional pollutants, there is no obvious and easy biodegradable toxic substances, including biodegradable organic matter, nutrients can be used as biological compounds, and suspended solids, etc.; third category toxic pollutants, which contains toxic and not readily biodegradable substances, including heavy metals, toxic compounds and not easily biodegradable organic compounds.
⑤
all kinds of industrial wastewater should be in accordance with national standards of environmental protection department under the Because of our low emission standards, standards for industrial wastewater still contains certain types of complex pollutants, can not be discharged to rivers and lakes and other natural water bodies, can only be stored locally seepage, could explore the use of soil absorption, plant uptake , natural evaporation, microbial uptake and other natural treatment methods.
as we explore the construction of ecological industrial wastewater treatment model: Considering the depth of underground water, sewage discharge volume, evaporation and other factors of natural construction of large-capacity local seepage, spill artificial lake, artificial pond, artificial channel to collect water; pool backfill soil to form soil absorption layer of clay absorb some heavy metals and pollutants; pool with soil aggregates in artificial islands, planting desirable aquatic plants, trees; can plant directly into the pool of sewage increase the pool of organic matter content, the huge pool of natural fungal reproduction, fungi absorb water with heavy metals and pollutants, fungi decompose organic matter in inorganic nitrogen and phosphorus to promote plant growth and reproduction of trees, a large number of plants, Trees will absorb a large number of heavy metals and pollutants; thus formed by natural evaporation, plant uptake, transpiration of plants and other natural methods of sewage purification; soil, fungi absorb the fixed, plants absorb heavy metals, pollutants ecological cycle.
9. the simple concept of using natural environmental success stories
9.1 Meili Paper Industry Company with the desert of Gansu purified waste water of paper forest deserts ⑥
CCTV . com News (News Network September 16, 2009 broadcast):
. . . . . . In recent years, the most serious land desertification in China one of the provinces - Ningxia, back from the desert land 490,000 ha, to achieve the desert desertification control faster than the speed of historical change. . . . . . For businesses, Ningxia free sand approach to encourage their participation in combating desertification. Meili was located in Zhongwei city invested 150,000 yuan per day for the purification of sewage, using a sand paper material such as planting poplar, they began to desert the papermaking waste water purified water forest, grass grows The desert has become full of vitality. Currently, Ningxia sand control over an area of 1,500 acres in more than 60 enterprises and individual households nearly 150,000 Afforestation and Desertification Control. Ningxia's forest cover from 1.3% in the early '50s to the present 8.9%.
9.2 Jinan Iron and Steel Company wastewater treatment lake excavation ⑦
was founded in 1958, Jinan, Shandong Iron and Steel Group Corporation is one of the largest, but also a more than 1000 years of steel production tons of large steel companies. In the past, this enterprise in Jinan as well as its steel exhausts have been plagued by waste, now, into the Jinan Iron and Steel, the reporter saw the mountains and surrounded by iron and steel enterprises.
steel area in the south of Ji Bao Shan was originally a bare rock, bare, barren hills and little vegetation. Jinan Iron and Steel signed a contract with the local government, the initiative to undertake the important task of greening Martin Hill. Ten years, the economic obligations of all employees of the steel back of green mountains of soil planting trees and laying of water pipes up the hill, digging artificial lakes; steel waste generated through the cooling cycle after treatment was injected into the artificial lake, freshwater sharks, carp , carp and other fish in the lake joyous play. . . . . .
9.3 Rongcheng City, Shandong Province, with a . . . Rongcheng City, Shandong, 200 hectares in southwest also used reed wetland, development and construction of a set of sewage treatment and protection of ecological stability in one urban sewage pond - wetland complex system of treatment works, the whole project up to 2 levels of treatment, the sewage treatment capacity up to 2 million cubic meters of treated wastewater to the city to clear into the sea after the discharge standards, the effective protection of the environment Sanggou Bay, the large population of aquatic life and plants to produce a swan food seagrass. Every year a large number of swans and other birds live in the Sanggou Bay. To further increase the large swans and other wild animals, protection, Rongcheng City, issued a series of specially developed protection system and provisions for the establishment of a large swan provincial nature reserves, marine nature reserves and provincial Chengshan Sang Ditch Bay Nature Reserve, and set up a Wildlife Conservation Society. Through a series of effective measures for whooper swans and other wild animals, creating a good living environment. . . . . .
9.4 Cao Qian Yang, Highland Village, Shaanxi farmers: The sand pit filter sewage ⑨
... As time goes, the masses of the living environment in rural areas are increasingly high requirements. Concentrated in the garbage after cleaning, Murakami addressing rural sewage treatment problem. This year, the county environmental protection department under the direction of advance of 42 villagers from each outfall constructed in front of length 1 m, width 0.8 m, 0.6 m deep treatment pond, which covered with gravel. Road access from home sewage sewage treatment pond, after sand filtration, purification, and then discharged into public waterways. Later, the villagers better replaced the gravel slag. In the vast rural areas, direct discharge of sewage long-term impact environmental health. In building sewage treatment plants in full swing right now the situation is difficult,UGGs, the first built by the farmers such a simple sewage treatment settling ponds after all, a really good way.
10. Summary
abandon the existing error pollution, sewage mode, in accordance with the principles of natural building ecological view of environmental protection, pollution treatment system, zero emission, theoretically, technically feasible , from the current situation of environmental protection is necessary, but the hardest is the concept of deep-rooted changes in the sewage.
