15、es, to reduce the amount of water discharged to achieve water resource, the system (device) similar to the small-scale sewage treatment plant for sewage treatment, according to population size, amount of water discharged arbitrarily choose a different size processing device used in the 0.6 m below t

16、he temperature above 5 areas and places, is currently being used in the septic tank and construction of an ideal substitute products; have obtained national patent, through the science and technology department, construction, organized by the office of the scientific and technological achievements a

17、ppraisal, conclusions of the device reached the advanced level of similar technology. the project will enable sewage to be purified in situ treatment, reduce sewage pollution of the environment, it will impact on our economy high-speed, stability, sustainable development play a role in protecting an

18、d promoting. will reduce the governments investment in building sewage treatment plants and sewage treatment plants operating expenses of the burden of pressure. the implementation of those who created pollution, who build, who managed approach, to avoid a disorderly discharge of sewage to ensure th

19、e unconditional building sewage treatment plants and unconditional access to sewage treatment plant wastewater discharge standards. second, process 3, the basic principles of the device is the use of micro-processing technology combined into a new type of highly efficient sewage purification plant.

20、it consists of bio-septic tank body, microbial flora, microbial carrier so on. mainly through the manual to strengthen technology, microbial flora introduced into the bio-septic tank within a one-time, in the pool gradually formed on the bio-carrier biofilm bacteria, the use of microbial flora (biof

21、ilms) of the metabolic role of the absorption, digestion, decomposition of sewage organic pollutants, so that transformed into a stable harmless substances, water purification purposes. the process uses a multi-level combination of biological treatment processes. the whole system buried in the groun

28、gh a special separation and purification equipment to cultivate domesticated, concentrated into a highly active preparation of cured, high-density multi-mix powder agent (or agent) to be stored. at normal temperature and pressure conditions, the powder agents can be stored six years. we developed a

29、high gsh series of microbial activity, high concentration (10 billion / g powder agents), high-mix (dozens - hundreds of kinds / g powder agents). applications for different bodies of water pollution, water quality and sewage pollution factors and concentration conditions, choose the degradation hav

30、e the best advantage of microbial groups (divided into a, b, c, d, e-type series) and the required the number of bacteria with special devices will "activate" after, and then put into the sewage treatment plant system (or the citys sewage river, drainage, ditch, lake), can absorb a

31、nd digest the sewage decomposition of organic pollutants and other harmful ingredients. the installation of septic tanks due to a special bio-bio-carrier, to facilitate micro-organisms attached to the conjunctiva and metabolism, will not be affected by the ambassador of water impact load over the lo

32、ss of a large number of micro-organisms. 4, the application scope of the technology and devices is currently the best way to sewage treatment. apply to office buildings, residential areas, residential areas, commercial communities, hotels, canteens, schools, resorts, hospitals, military barracks, tr

33、ains, ships and other domestic sewage purification treatment. reposted elsewhere in the paper for free download v. features 1. not all of an area of surface area of the device planted in the ground, not an area of surface area. chi upper body can be used as green areas, parking lots and roads. when

34、the user of the terrain are restricted, according to the needs of users, according to non-standard layout, on-site manufacture, depending on the terrain arrange any combination of the layout of the situation. 2. low cost, small investment, the technology uses the biochemistry + physical chemistry pr

35、inciples, combined with modern scientific and technological research made fast to purify the sewage of the harmful substances. with the traditional process and improvement in efficiency compared to other technologies for more than five times, the product can be industrialized mass production, and th

36、us with the traditional sewage treatment equipment (system) compared to a one-time investment can save 50-60%. 3. low operation cost of the device has successfully used the fluid studies (no pump) to control the whole process of sewage treatment, done automatically when there is water, no sewage aut

37、omatically outage, completely solved the water during the day a large amount of a small amount of water at night, even late at night almost no lead to uneven flow of sewage and other technical problems; by biological technology to achieve the larger the volume of effluent, processing speed faster, r

38、educing the volume of effluent, processing speed automatic slow down at night there is no sewage when equipped with the basic outage such as automatic process. 4. do not need someone a long life cycle management and clear residue of sewage treatment using the device does not require expert managemen

39、t, long-term savings in management costs for the user. the process uses a non-residual sludge biological treatment technology, micro-organisms to organic matter and harmful pollutants into the air (nitrogen oxides), heat and water, do this, clear residue long life cycle, under normal circumstances t

40、he main facilities in three to five years qingtao only once, reducing the clean-up costs. 5. dealing with purification effect is good because the device is the use of sewage flows to control the entire sewage treatment process, the device is equipped with a special bio-carrier and a large number of

41、gsh microbial flora, the use of microbial metabolic function that can automatically adjust quickly sewage water and the relationship between the treatment effects, so treatment results are quite stable, through monitoring, purified water is better than the national gb8978-1996 integrated wastewater

42、discharge standard. 6. adaptability, without the restriction of the device system is not temperature, climate, both in the central plains and other regions of china, the same can be run (because the system buried in the ground, easy to constant temperature and thermal), and the results will be fully

43、 compliance with state requirements. 7. run no noise, no smell of the system all the major device buried in the ground, run-time no noise, no smell secondary pollution. especially suitable for residential, office, medical and other environments. 8. water resource recycling of water back to the syste
