Sewage treatment is recommended to use conduction aeration biofilter, conduction aeration biofilter Conduction Current Biofilter (referred to as CCB) so that the sewage in the same treatment tank, to complete the process of aeration → sedimentation → secondary aeration → secondary sedimentation, etc., to solve the other wastewater treatment requires four pools to complete the process. Especially in the continuous water intake conditions, the realization of water intake → aeration → precipitation → water outlet gap aeration, at the same time, the realization of sludge reflux, the entire operation without idling, the advantages of its more prominent than other sewage treatment methods, the treatment effect is particularly significant, CCB sewage treatment equipment is the AB method, the SBR method, the A2O method, the contact oxidation method, as well as two aeration and two sedimentation, gap aeration and other sewage treatment equipment, the newer generation of products. In November 2009, the Ministry of Science and Technology of the State as "innovation projects", project code 09C26215205564; in December 2009, the Ministry of Environmental Protection of the State will be listed in the product as "the State encourages the development of environmental protection technology catalog" (Huifa 2009146) (Huanfa 2009146); in May 2010, the Ministry of Science and Technology, the Ministry of Environmental Protection, the Ministry of Commerce, the State General Administration of Quality Supervision, Inspection and Quarantine review recognized the "Conductive Aeration Biofiltration Pond" as a national key new product, its number is 2010GR467010.
CCB in China's Beijing, Shandong, Hebei, Guizhou, Shanxi, Sichuan, Inner Mongolia, Heilongjiang Guangdong, Guangxi, Shaanxi, Gansu, Ningxia, Xinjiang, Jiangsu, Jilin, Henan, Hubei, Tianjin and other places have been examples of engineering cases, cases and life, hospitals, chemical, slaughtering, food, flax, alcohol, pharmaceutical and other wastewater treatment, a large number of applications have proved that: the effluent quality of CODcr is generally in the 20mg / L or less, a minimum of 5.95mg / L; BOD5 is generally in the 10mg / L or less, a minimum of 3.50mg / L The lowest BOD5 is below 10mg/L, and the lowest SS is below 20mg/L, and the lowest SS is below 6.55mg/L.
CCB wastewater treatment equipment draws on the design of SBR, AO, A2O, oxidation ditch, activated sludge and biofilter, biological rotor, bio-contact oxidation, biofilm and anaerobic digestion, hydrolysis and acidification, and anaerobic biological treatment such as UASB, etc.
CCB wastewater treatment equipment has been designed for the treatment of secondary or tertiary wastewater. The innovative process technology of intensive sewage treatment developed by the State Intellectual Property Office in 2005, the State Intellectual Property Office as a national patent product, Patent No.: ZL200420033672.4.
