Conductive aeration biofilter is China's independent intellectual property rights of the new sewage treatment process, according to the subsequent treatment process, 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. Aeration biofilter, ozone - conduction aeration biofilter, etc.
Conductive aeration biofilter in the old sewage treatment works upgrading, nitrogen and phosphorus removal, water reuse and other processes combined to develop AB method - conduction aeration biofilter; A/O method - conduction aeration biofilter; A2 / O method - conduction aeration biofilter; oxidation ditch - conduction aeration biofilter; SBR - conduction aeration biofilter; biological contact oxidation - conduction aeration biofilter and other deep treatment processes. Bio-contact oxidation-conducted aeration biofilter and other deep treatment processes.
Conductive aeration biofilter fully draws on the aeration biofilter method, contact oxidation, biofilm method, gap aeration method, artificial fast filtration, sedimentation and separation method, nitrification back to nitrification method, fast filtration 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, a new technology. 2005 to obtain a national patent.
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, cases involving life, hospitals, chemical industry, slaughtering, food, linen, 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. To achieve the reuse of water to achieve zero discharge.
Conductive aeration biofilter so that the sewage in the same treatment tank, complete two aeration, two precipitation, two filtration, to solve the other sewage treatment requires four pools to complete the process, especially in the continuous water intake conditions, the realization of intermittent aeration, activated sludge reflux, the entire operation is not idle, and the advantages of its more than dealing with other methods are more prominent, the treatment effect is particularly significant. In 2009, it was listed as "innovative project"; in December of the same year, it was listed as "environmental protection technology encouraged by the state"; in 2010, it was listed as "national key new product"; In 2010, it was listed as "National Key New Product"; and in 2012, it was listed as the environmental protection technology that is recommended and encouraged to be used during the 12th Five-Year Plan period, when the country increases investment in the upgrading of towns, villages and towns, rural areas, industry, aquaculture, as well as urban sewage treatment plants, nitrogen and phosphorus removal, and water reuse, and other fields.
