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-ducted flow aeration biofilter, etc.
Conductive aeration biofilter in the old sewage treatment project upgrading, nitrogen and phosphorus removal, water reuse and other processes combined to develop AB method - conductive aeration biofilter; A/O method - conductive aeration biofilter; A2 / O method - conductive aeration biofilter; oxidation ditch - conductive aeration biofilter; SBR - conductive aeration biofilter; biological contact oxidation - conductive aeration biofilter and many 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 there 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.
Infiltration aeration biofiltration tanks so that the sewage in the same treatment tank, to complete the two times of aeration, two times of sedimentation, two times of filtration, to solve the other sewage treatment During the 12th Five-Year Plan period, the state has invested more in the upgrading of urban, rural, industrial, aquaculture, and municipal wastewater treatment plants, denitrification and phosphorus removal, water reuse and other fields to recommend the use of environmental protection technology and encourage the development of. Mainly used in the following areas:
(1) community sewage, small town sewage, sewage treatment and reuse of urban sewage
①, towns, villages, towns, rural areas, residential communities and development zones of sewage;
②, hotels, restaurants, nursing homes, hospitals, schools, shopping malls, and office buildings sewage;
③, stations, airports, docks, etc. Sewage.
(2), industrial wastewater treatment and reuse
①, flax wastewater treatment;
②, dairy and farm wastewater treatment;
③, starch wastewater treatment;
④, tobacco production and living wastewater treatment
⑤, high ammonia nitrogen wastewater treatment of chemical plants;
⑥, alcohol wastewater treatment;
7, food wastewater treatment;
8, slaughtering wastewater treatment;
9, pharmaceutical wastewater treatment.
(3), sewage treatment plant upgrading and special requirements of sewage treatment
①, urban sewage treatment plant upgrading and water reuse projects
②, there are requirements for nitrogen and phosphorus removal of wastewater treatment
(3), the requirements of the depth of the treatment of wastewater, do not increase the tertiary treatment facilities, the effluent can meet the standards of reuse.
