Problems solved by technology

[0003] The long-term troubles of sewage treatment in my country are mainly investment and operating costs. The traditional activated sludge process and anaerobic-aerobic activated sludge process (A / O, AA / O) and the derived intermittent activated sludge process ( SBR method), integrated activated sludge method (UNITANK), BIOLAK method, two-stage method (AB method), biofilm method, biological contact oxidation method, oxidation ditch method, CASS, ICEAS, land treatment system and other processes and efficient anaerobic Oxygen bioreactors (UASB, ABR, EGSB, IC, etc.) and bioreactors such as BAF, membrane bioreactor, biological fluidized bed, moving force bed bioreactor, etc., cannot conveniently select appropriate process equipment according to the characteristics of wastewater quality , and optimize the biological treatment system, resulting in the difficulty of fully exerting the efficiency of the biological treatment system, wasting investment and energy consumption, etc.
