Biological wastewater treatment system using anaerobic and aerobic microorganisms and its treatment method

摘要

[purpose];An anaerobic treatment method, which is a treatment method of high concentration wastewater, and an aerobic treatment method which is a treatment method of low concentration and wastewater, is to operate the wastewater treatment apparatus easily, economically and efficiently, and treat wastewater.;[Configuration];In the process of biologically treating organic wastewater, an anaerobic treatment tank (1) for anaerobic treatment, an aerobic contact tank (2) for aerobic treatment and a settling tank (8) for solid-liquid separation are installed at the upper and lower portions of the bioreactor Anaerobic treatment of anaerobic and aerobic anaerobic and aerobic microorganisms and anaerobic treatment tank installed in the lower part of the bioreactor are performed anaerobic treatment. In the aerobic contact tank installed in the upper part, anaerobic treatment is applied to the treated water. Aerobic treatment.
