In the process design selection, due to China's sewage treatment started late, the development of fast, sewage treatment process is mainly biochemical treatment, the common process of contact oxidation, AB method, A/O method, oxidation ditch, SBR, aeration biofilter, infusion aeration biofilter and so on.
A Conductive aeration biofilter is China's independent intellectual property rights of the new process of sewage treatment, according to the different subsequent treatment processes, it is divided into: hydrolysis-conductive aeration biofilter, anaerobic-conductive aeration biofilter, air flotation-conductive aeration biofilter, fast sedimentation-conductive aeration biofilter, ultrasonic-conductive aeration biofilter, microwave-conductive aeration biofilter, ozone-conductive aeration biofilter, and so on. Aeration biofilter, ozone - conduction aeration biofilter, etc.
The second inflow aeration biofilter in the old sewage treatment project upgrading, nitrogen and phosphorus removal, water reuse and other processes, the development of AB method - inflow aeration biofilter; A/O method - inflow aeration biofilter; A2/O method - inflow aeration biofilter; oxidation ditch - inflow aeration biofilter; SBR - inflow aeration biofilter; biological contact oxidation - inflow aeration biofilter and many other deep treatment processes. Bio-contact oxidation-conducted aeration biofilter; biological contact oxidation-conducted aeration biofilter.
Three Conductive aeration biofilter fully draws on the aeration biofilter method, contact oxidation, biofilm method, interstitial aeration method, artificial fast filtering, sedimentation and separation method, nitrification back to nitrification, fast filtering of water, such as the design of eight, and combined with the secondary or tertiary wastewater treatment process and the development of a new wastewater treatment process, new technologies. Conductive aeration biofilter in China's Beijing, Shandong, Hebei, Guizhou, Shanxi, Sichuan, Inner Mongolia, Heilongjiang, Jiangsu, Jilin, Henan, Hubei, Tianjin, Xinjiang and other places have been examples of engineering cases involving life, hospitals, chemical industry, slaughtering, food, flax, alcohol, pharmaceuticals, pickled vegetables and other areas of sewage treatment. A large number of applications have proved that: the effluent water quality CODcr is generally below 20mg/L, the lowest 5.95mg/L; BOD5 is generally below 10mg/L, the lowest 3.50mg/L; SS is generally below 20mg/L, the lowest 6.55mg/L.
The four infiltration aeration biofiltration tank makes the wastewater in the same treatment tank to complete the two times aeration, two times precipitation, two times filtration, solving the other problems. Precipitation, two filtration, to solve other sewage treatment requires four pools to complete the process, especially in the continuous water intake conditions, to achieve intermittent aeration, activated sludge reflux, the entire operation without idling, the advantages of its more traditional treatment methods are more prominent, the treatment effect is particularly significant. 2009 August, the Ministry of Science and Technology of the State as an "innovation program In August 2009, it was listed as "Innovative Project" by the Ministry of Science and Technology of China; in December 2009, it was listed as "Catalog of Environmental Protection Technologies Encouraged by the State" by the Ministry of Environmental Protection of China; in May 2010, it was recognized as "National Key New Product" by the Ministry of Science and Technology of China, Ministry of Environmental Protection of China, Ministry of Commerce of China, and General Administration of Quality Supervision, Inspection and Quarantine of China. "In May 2010, it was recognized by the Ministry of Science and Technology, the Ministry of Environmental Protection, the Ministry of Commerce and the General Administration of Quality Supervision, Inspection and Quarantine as a "National Key New Product".
Five in the strengthening of the equipment set, because the biochemical is the mainstream of our country for sewage treatment, the past is mainly to develop biochemical process is the main core of biochemical treatment technology is to cultivate micro-organisms, commonly used in biochemical treatment of sewage, through the aeration of sewage to cultivate micro-organisms, due to the aeration of the micro-organisms produced by the method of biochemistry can not meet the needs of sewage treatment, the design is often used to increase the amount of aeration, expanding the aeration, the design is often a good idea. Take to increase the amount of aeration, expand the aeration tank, increase the extension of sewage long residence time of these three ways to make up for the shortcomings of the process. But due to the climate environment, impact load, water quality factors such as water quality is difficult to stabilize the standard, and then there are engineering upgrades, engineering renovation, as well as engineering changes and changes, up and up, not only costly, time-consuming, labor-consuming.
Six microbial generator draws on aerobic biological method, embedded microorganisms solid method, biological bacteriophage addition method and other four design techniques and developed a new sewage purification equipment. The equipment can save sewage treatment investment, reduce sewage treatment occupies an area, save sewage treatment operating costs, eliminate sewage odor, reduce sludge discharge and other conditions, so that the sewage after intensive treatment is better than the national standard, can be discharged or recycling, in 2014 was awarded a national patent.
Seven microbial generator is waste water treatment in the waste reinforcement equipment, can be used in conjunction with a variety of wastewater or sewage treatment process, according to the subsequent process, can be organically combined into: AB method - microbial generator reinforcement process; A/O method - microbial generator reinforcement process; A2 / O method - microbial generator reinforcement process; oxidation ditch - microbial generator reinforcement process; SBR- Microbial generator enhanced process; contact oxygen method - microbial generator enhanced process, membrane bioreactor - microbial generator enhanced process; aeration biofilter - microbial generator enhanced process; aeration biofilter - microbial generator enhanced process.
The eight microbial generators can be used in new sewage treatment projects; can also be used to upgrade the old sewage treatment projects; can also be used for nitrogen and phosphorus removal, rivers, lakes, river landscape management; wetland park ecological restoration; sewage treatment plant sludge reduction, water reuse, high concentration, high ammonia and nitrogen, high salinity, heavy metals, and other toxic and hazardous wastewater treatment fields.
The use of microbial generators to strengthen the treatment process has been in China's Chongqing, Hebei, Guizhou, Jilin and other places have been examples of engineering cases involving high salt wastewater, hospital sewage, chemical wastewater, slaughtering wastewater, food wastewater, pharmaceutical wastewater, printing and dyeing wastewater and other fields. A large number of applications have proved that: the effluent water quality CODcr is generally below 20mg/L, the lowest 5.95mg/L; BOD5 is generally below 10mg/L, the lowest 3.50mg/L; SS is generally below 20mg/L, the lowest 6.55mg/L.
