technical field

The invention relates to an ecological restoration and environmental protection self-drainage system, which belongs to six fields of energy-saving technology and equipment, high-efficiency energy-saving products, energy-saving service industry, advanced environmental protection technology and equipment, environmental protection products and environmental protection services; in order to save the current loss of water resources in the motherland , urban waterlogging, dry farmland, inland rivers and surface environment deterioration and research and development of governance strategies.

Background technique

With the continuous and rapid development of China's economy, the continuous increase of urbanization and industrialization, the environmental pollution is becoming more and more serious, and the country is paying more and more attention to environmental protection. Entering the 21st century, the global environmental protection industry has entered a stage of rapid development, and has gradually become an important force supporting the growth of industrial economic benefits, and is becoming an important goal and key for many countries to innovate and adjust their industrial structure. During the "Tenth Five-Year Plan" period, due to the country's increased investment in the construction of environmental protection infrastructure, which has effectively stimulated the market demand of related industries, the overall scale of the environmental protection industry has expanded rapidly, the industrial field has continued to expand, the industrial structure has been gradually adjusted, and the industrial level has been significantly improved. Under the requirements of the development of circular economy in environmental protection technology, since 2007, the subject of environmental protection expenditure has been officially included in the national financial budget, and the government has put forward new ideas and new countermeasures for environmental protection. The speed is further improved.

In 2007, China adopted comprehensive measures to promote pollution reduction. The proportion of coal-fired units equipped with desulfurization facilities in all thermal power units increased from 12% in 2005 to 48%, and the urban sewage treatment rate increased from 52% to 60%. The annual national chemical oxygen demand emission was 13.833 million tons, a decrease of 3.14% compared with 2006; the sulfur dioxide emission was 24.681 million tons, a decrease of 4.66% compared with 2006. Prevention and control has shifted from passive response to active prevention and control, and the historic transformation of environmental protection has taken solid steps.

China's environmental protection industry is still in the stage of rapid development, the overall scale is relatively small, and its boundaries and connotations are still being extended and enriched. With the development of China's social economy and the adjustment of industrial structure, the direct contribution of China's environmental protection industry to the national economy will change from small to large, and gradually become an industry that improves the quality of economic operation, promotes economic growth, and improves economic and technological grades. The direction of industrial connotation expansion will mainly focus on clean technology, clean products, environmental services, etc. The concept of China's environmental protection industry will also evolve into: "environmental industry" or "green industry".

During the "Eleventh Five-Year Plan" period, China's environmental protection industry is expected to maintain an average annual growth rate of 15%-17%. The key areas of environmental protection investment mainly include water environment, atmospheric environment, solid waste, ecological environment, nuclear safety and radiation environmental protection construction and environmental capacity building. In 2010, the total annual income of the environmental protection industry will reach 880-1 trillion yuan, including 660 billion yuan in comprehensive utilization of resources, 120 billion yuan in environmental protection equipment, and 100 billion yuan in environmental services.

The State Council's Research and Deployment Conference on Accelerating the Development of Energy Conservation and Environmental Protection Industry requires that to accelerate the development of energy conservation and environmental protection industry, we must not only have policy support, but also innovate mechanisms to encourage and guide the active participation of social capital, including private capital. First, promote energy conservation, environmental protection and the consumption of recycled products. Government vehicles and buses should take the lead in promoting the use of new energy vehicles and simultaneously improve supporting facilities. By 2015, increase the market share of high-efficiency and energy-saving products to more than 50%. Second, we must improve the level of industrial technology and equipment. Promote the upgrading of energy-saving technology and equipment in areas such as high-efficiency boilers and high-efficiency motors. Accelerate the development and promotion of air, water, soil and other pollution control technology and equipment. Intensify research on key common technologies and improve independent innovation capabilities. Develop and expand contract energy management and other energy-saving and environmental protection service industries. Third, we must speed up the construction of key energy-saving and environmental protection projects, improve urban environmental infrastructure such as sewage pipe networks, and carry out green building actions. Fourth, we must create a favorable market and policy environment, improve regulations and standards, and improve prices, charges and land policies. The fifth is to increase the support for investment in the central budget and special funds for energy conservation and emission reduction, and continue to arrange budgetary expenditures for state-owned capital operations to support key enterprises in implementing energy conservation and environmental protection projects. Carry out extensive international exchanges and cooperation.

In recent years, natural disasters such as extreme weather, tsunamis, earthquakes, and greenhouse effect have occurred frequently, which have drawn people's attention. Environmental issues have gradually become popular topics, and the term "environmental protection" has become very fashionable. We know that the development of energy-saving and environmental protection industries ultimately depends on the forced promotion of policies. Judging from the current global situation, this kind of policy driving force has become stronger and stronger, which will make the energy-saving and environmental protection industry enter a new era.

After the global financial crisis, the issue of energy conservation and environmental protection has been pushed to the forefront. The Copenhagen climate conference urged developed and developing nations to overcome their differences and reach a legally binding agreement to cut greenhouse gas emissions. Behind the holding of the Copenhagen climate conference, on the one hand, global environmental problems have indeed become more and more severe in recent years; on the other hand, after the financial crisis, developed countries hope to use environmental protection issues to put pressure on developing countries to enhance their own relative competitiveness.

For example, a few years ago, my country formulated a binding target of reducing energy consumption per unit of GDP by 20% during the "Eleventh Five-Year Plan" period. At that time, it was difficult to achieve it; The possibility is greater. This means that the government has made greater efforts in this regard.

In general, under the background of policy efforts, my country's energy conservation and environmental protection will enter a new era. From the perspective of international experience, my country's environmental protection investment curve (that is, the proportion of environmental protection investment in GDP) has just passed the first inflection point and entered a period of accelerated growth. During the "Eleventh Five-Year Plan" period, my country's environmental protection investment will continue to grow rapidly, and the proportion of GDP will increase by 0.31 percentage points to 1.53%. In the medium and long term, the high point of this ratio should be between 2.5% and 3%. The rising period of the environmental protection investment curve will last for at least 10 years, and the corresponding compound annual growth rate should be .

Contents of the invention

The purpose of the present invention is: according to the urgent needs of the market in the new situation of energy saving and environmental protection in my country, a kind of ecological reduction and environmental protection self-drainage system is developed directionally, which is another urban pipeline project after tap water. It is necessary to invent methods for local areas to achieve ecological restoration; start with energy conservation and emission reduction, and scale pollution control targets to the source; the scale ranges from urban overall planning to small farm households; the main subject of this project is: focus on water conservation The purpose is to conserve water, increase income and reduce expenditure, control pollution and protect the environment; extend the following subordinate rights to require corresponding protection; everyone knows that there is a long way to go to protect water and soil resources; however, how many water-deficient cities use extravagant water, which cannot be saved, let alone restored, and ruins and destroys our great country. Therefore, to save the current loss of water resources in the motherland, urban waterlogging, dry farmland, and deterioration of inland rivers and surface environments, we have developed governance strategies.

The ecologically restored and environmentally friendly self-draining system is to send domestic wastewater to the sky instead of being discharged into the rivers, lakes and seas. A sky pool is built on each roof, and the waste water evaporates naturally from the sky pool to the sky, making a city a water resource of one day. It will no longer become "a river of sewage" and "go to waste". Bacteria, microorganisms and harmful substances in wastewater are directly killed by infrared and ultraviolet radiation in a larger area of sunlight, and natural evaporation will replenish humidity to the dry environment at the same time, alleviating urban pollution. The heat island effect caused by man-made Kashi special landforms produced by the construction of urbanization can make up for the ecological disasters caused by soil erosion, and reduce the temperature of the town by 3-5 degrees Celsius as much as possible, which is similar to the suburbs, thereby saving a lot of air-conditioning electricity and reducing air-conditioning heat. Discharge, this part of the waste water is temporarily not considered to collect flushing water.

In the above-mentioned ecological restoration and environmental protection self-drainage system, the Tianchi overflow pipe is set to collect and store rainwater, and at the same time, it can effectively control urban waterlogging.

The ecological restoration and environmental protection self-drainage system described above can reach a higher level of building height, and fire water pipes and joints can be attached to the bottom of the pool to increase the fire safety factor of the building.

The ecological reduction and environmental protection self-draining system is characterized in that: after the natural evaporation of cities and towns, the excess domestic wastewater is sent to the farmland, so as to avoid the unreasonable discharge of urban residents' water resources into inland rivers and cause the deterioration of the river pollution environment; Ecological imbalance caused by farmers' lack of water for production.

The ecologically restored and environmentally friendly self-draining system must be used in conjunction with an odorless energy-saving and emission-reducing toilet, and the flushing water can be collected in a special pipe, so that the concentration of urban organic excreta can produce resource value, and the mature biogas public technology can be used to achieve The effect of anaerobic sterilization can solve the phenomenon of stench in open ditches and open channels and inland rivers: biogas is directly supplied to towns or communities; biogas slurry and residue are transported to the suburbs or on the roof of your own house to produce pollution-free vegetables, and the photosynthesis of leaves is absorbed by the roots to form metabolism. The positive energy of ecological restoration serves multiple purposes.

The ecological reduction and environmental protection self-drainage system mentioned above, this technical solution is also suitable for the collective protection of the environment by rural villagers’ organizations or the establishment of an ecological restoration and environmental protection self-drainage system by farm households to flow fertilizer water into their own fields to avoid direct infiltration of surface pollutants into wells Affect the safety and health of drinking water sources.

The ecological reduction and environmental protection self-drainage system mentioned above only needs to use a small part of about 1/10 of the volume of the septic tank in the original community to change it into a biogas digester according to the technical requirements of biogas, and most of them hardly need major changes. If it can achieve the function of accumulation and sedimentation, it can meet the requirements of pipeline transportation. Once the pipeline is installed, water will come naturally; when used with odorless energy-saving and emission-reducing toilets, the water saving effect is about ten times that of traditional toilets, greatly reducing pipeline investment, and waste water and biogas slurry can also be sent to the city. In all directions and in the suburbs, pipe networks are distributed in the vicinity of planting areas, including urban green areas. For areas with sufficient water resources, only biogas slurry pipelines need to be considered.

The ecological restoration and environmental protection self-draining system described above, combined with the vegetable basket project, uses the soil or soilless vegetable cultivation technology on the roof to convert urban sewage into positive energy, allowing organic nutrients to digest excess parts on the spot and then transport them nearby, so as to control the transportation cost Reduce to the lowest value, let urban residents visit green homes in person, step out from growing vegetables on the Internet, experience the fun of ecological cycle, personally cultivate fresh and living vegetables that are safe from drought and flood without pollution, improve life and health literacy, and effectively adjust the manpower and material resources of vegetable distribution and market operations Consumption, improve the effective utilization of land, reduce the loss of nutrition from the vegetable garden to the dining table, and the pollution caused by the loss of every link of the externally transferred vegetables to the local environment.

The ecologically restored and environmentally friendly self-draining system only needs to change the concept of decision makers. This plan has reached a consensus, and the territorial government can exempt a large amount of land acquisition fees, investment expenses, and operating expenses for sewage treatment plants, and exempt sewage treatment plants from leaving waste water. Mud secondary pollution, saving a lot of water supply resources; urban residents will share the saved annual sewage treatment fees, and also save a lot of water for flushing toilets; farmers get water resources, biogas slurry is the best quality organic fertilizer and organic pesticides; investment and development operators It is naturally profitable. According to the principle of whoever invests, he will benefit. Biogas can be used as fuel and directly supplied to citizens to collect user fees, and biogas slurry and residue can be used as fertilizer to charge farmers. The good management is far beyond real estate development, because it is the state's attention and support. It is possible to continue the macro issue of operating circular economy; it is hoped that with the ecological restoration and environmental protection self-drainage system as enlightenment, no longer ignorant, integrate resources, gather mature technologies from all walks of life, and strive to realize the "Chinese Dream" of national rejuvenation.

The beneficial effects of the present invention are:

An ecologically restored and environmentally friendly self-drainage system, which can effectively alleviate the heat island effect caused by the man-made Kashi landform caused by urbanization; effectively protect the loss of water resources, and transfer the direction of pollution control to the accuracy of pollution sources. The positive energy promotes the development of organic agriculture. The ecological restoration and environmental protection self-drainage system lays the foundation for the future that requires the application of organic fertilizers, and creates the highest quality organic fertilizers and organic pesticides for farmers; the ecological restoration and environmental protection self-drainage system is to show gratitude to ancient civilizations The great movement of the earth is the creation needed to feed the earth and repay the earth.

Detailed ways

The ecologically restored and environmentally friendly self-draining water system described above is a necessary supporting system for urbanization. According to the mechanism of what comes, there must be gone, and the ecological restoration must go to the right place to strive for ecological balance. This plan is another one after tap water. The scale of urban pipeline projects ranges from urban overall planning to small farm households; according to the schematic diagram of the ecological restoration and environmental protection self-drainage system, the analysis is as follows, domestic wastewater is included in property management, and collected in a unified manner: collected from kitchen 6 Washing dishes and vegetables, toilets 8, laundry, bathing, kitchen and bathroom sewage source 10, the waste water is separated by the crude water filter 11, sent to the sewage clarification tank 20 by the crude water conveying pipe 14, and then sent to the Tianchi sewage conveying pipe 19 to Tianchi 1 free, each roof is unified to build a Tianchi, in fact, Tianchi only needs to add a Tianchi overflow pipe body 23 above the water outlet above the existing natural underwater water pipe of the flat-roofed house according to the specific load capacity of the design, so that the Tianchi can be set up at the same time Collect and hoard rainwater so that the water surface reaches 20mm-500mm. The highest point is set as the safety limit overflow port 21, and the place 100mm=200mm down from the safety limit overflow port 21 is set as the current limiting hole 22, and the natural water is kept at the first time. In our Tianchi; when the water volume exceeds the limit water level we set, it will be drained from the original design of the natural water overflow, and the flow-limiting hole 22 is set as the elastic drop. This setting can most effectively control the waterlogging phenomenon of urban roads Even if the downpour allows N small reservoirs to share the pressure for the urban drainage system; the concentrated feces in the toilet 8 are directly sent to the biogas digester 12 through the concentrated feces delivery pipe 9, and the generated biogas is sent to the kitchen 6 through the biogas delivery pipe 4, and the biogas slurry layer The biogas slurry at 15 is pressurized by the biogas slurry delivery pipe 5 and sent to the vegetable garden 2, the urban green belt 3 and the suburban farmland 7. The biogas residue in the biogas residue layer 15 is regularly pumped to the farmland by tanker as indicated by the route of the biogas residue. Base manure and sewage in sunny days are pumped into the Tianchi through the sewage delivery pipe 19 of the Tianchi after pressurization, and the excess sewage after evaporation is pressurized and transported to the urban green belt 3 and the suburban farmland 7 as far as possible to reach the plant root system through the delivery pipe 18 to achieve the purpose of ecological restoration. This strategy saves the current loss of water resources in the motherland, urban waterlogging, dry farmland, and deterioration of inland rivers and surface environments.

The ecologically restored and environmentally friendly self-draining system is to send domestic waste water to the sky instead of being discharged into the rivers, lakes and seas. A sky pool is built on each roof, and the waste water evaporates naturally from the sky pool to the sky, so that the water resources of each city are not exhausted. Then it becomes "a river of sewage" and "doesn't flow". Bacteria, microorganisms and harmful substances in wastewater are directly killed by infrared and ultraviolet radiation in a larger area of sunlight, and natural evaporation is added to the dry environment at the same time. The amount of evaporation is the same as The temperature adjustment efficiency is directly proportional to alleviate the heat island effect caused by the man-made Kashi special landform produced by urbanization, make up for the ecological disaster caused by soil erosion, and reduce the temperature of the town by 3-5 degrees Celsius as much as possible, which is similar to the suburbs, and saves money from it. A large amount of air-conditioning consumes electricity while reducing the heat discharge of the external unit of the air-conditioning. This part of the waste water is not considered for the time being to collect water for flushing the toilet; the enlightenment of a technical plan, the implementation of policy guidance, and the popularization and promotion of it can realize the initiative of artificial scientific control and regulation of nature. sex.

The ecologically restored and environmentally friendly self-drainage system not only achieves a higher level of building height and water, but also can be equipped with fire-fighting water pipes and interfaces at the bottom of the pool, increasing the fire safety factor of buildings.

The ecologically restored and environmentally friendly self-draining system sends excess domestic wastewater to the farmland after satisfying the natural evaporation of cities and towns, so as to avoid the unreasonable discharge of water resources by urban residents into inland rivers and cause river pollution and environment deterioration; solve the problem of surrounding farmers due to lack of The ecological imbalance caused by the production of water sources; this link of investment can be integrated with the developer and the government to charge the emitter or the beneficiary farmers, which is one more source of paying customers than the sewage treatment plant.

The ecologically restored and environmentally friendly self-draining system must be used in conjunction with an odorless energy-saving and emission-reducing toilet, and the flushing water can be collected in a special pipe, so that the concentration of urban organic excreta can produce resource value, and the mature biogas public technology can be used to achieve The effect of anaerobic sterilization can solve the phenomenon of stench in open ditches and open channels and inland rivers: biogas is directly supplied to towns or communities; biogas slurry and residue are transported to the suburbs or on the roof of your own house to produce pollution-free vegetables, and the photosynthesis of leaves is absorbed by the roots to form metabolism. The purpose of ecological restoration is positive energy; biogas production is a mature public technology combined with this system to jointly develop organic energy.

The ecological reduction and environmental protection self-drainage system mentioned above, this technical solution is also suitable for the collective protection of the environment by rural villagers’ organizations or the establishment of an ecological restoration and environmental protection self-drainage system by farm households to flow fertilizer water into their own fields to avoid direct infiltration of surface pollutants into wells Affect the safety and health of drinking water sources; enlightenment from a technical solution and policy guidance can share positive energy.

The ecological reduction and environmental protection self-drainage system mentioned above only needs to use a small part of about 1/10 of the volume of the septic tank in the original community to change it into a biogas digester according to the technical requirements of biogas, and most of them hardly need major changes. If it can achieve the function of accumulation and sedimentation, it can meet the requirements of pipeline transportation. Once the pipeline is installed, water will come naturally; when used with odorless energy-saving and emission-reducing toilets, the water saving effect is about ten times that of traditional toilets, greatly reducing pipeline investment, and waste water and biogas slurry can also be sent to the city. In all directions and in the suburbs, pipe networks are distributed nearby for planting areas, including urban green areas. For areas with sufficient water resources, only biogas slurry pipelines need to be considered; enlightenment of a technical plan and policy guidance can achieve the transmission of positive energy.

The ecological restoration and environmental protection self-draining system described above, combined with the vegetable basket project, uses the soil or soilless vegetable cultivation technology on the roof to convert urban sewage into positive energy, allowing organic nutrients to digest excess parts on the spot and then transport them nearby, so as to control the transportation cost Reduce to the lowest value, let urban residents visit green homes in person, step out from growing vegetables on the Internet, experience the fun of ecological cycle, personally cultivate fresh and living vegetables that are safe from drought and flood without pollution, improve life and health literacy, and effectively adjust the manpower and material resources of vegetable distribution and market operations Consumption, improve the effective utilization of land, reduce the loss of nutrition from the vegetable garden to the dining table, and the pollution caused by the loss of every link of externally transferred vegetables to the local environment; a good technical plan enlightenment and policy guidance can achieve the promotion of positive energy. Implement ecological restoration with practical actions to realize visible green towns and homes.

The ecologically restored and environmentally friendly self-draining system only needs to change the concept of decision makers. This plan has reached a consensus, and the territorial government can exempt a large amount of land acquisition fees, investment expenses, and operating expenses for sewage treatment plants, and exempt sewage treatment plants from leaving waste water. Mud secondary pollution, saving a lot of water supply resources; urban residents will share the saved annual sewage treatment fees, and also save a lot of water for flushing toilets; farmers get water resources, biogas slurry is the best quality organic fertilizer and organic pesticides; investment and development operators Naturally, it is profitable. According to the principle of whoever invests, whoever benefits, biogas can be used as fuel and directly supplied to citizens to collect usage fees, and biogas slurry and residue can be used as fertilizer to charge farmers; when the water for flushing toilets is reduced to 1/5 of other domestic water, it will After the pressure of the outside pipe network is boosted to the same pressure as tap water, it is only 1/5 of the unit cross-sectional area of the tap water supply pipe network, which is simpler and easier to implement than the sewage pipeline for sewage treatment, and can continue to operate to generate huge corporate and social benefits. , It can also radiate and extend many industrial chains. Good management goes far beyond real estate development, because it is a macro issue that can continue to operate the circular economy that the state pays attention to and supports; I hope to use the ecological restoration and environmental protection self-drainage system as an enlightenment, no longer ignorant, integrate resources, and unite all walks of life Mature technology, striving to realize the "Chinese Dream" of national rejuvenation.
