BIOLOGICAL DISPOSAL APPARATUS OF FOUL WATER AND SEWAGE AND METHOD FOR BIOLOGICAL DISPOSAL THE SAME

摘要

The present invention divides sewage and sewage using biological treatment methods to effectively remove organic matter and suspended solids within residence time, and to treat nitrogen and phosphorus with high efficiency, and install microbial contact media inside the anaerobic tank. Anaerobic treatment step to provide a proliferation environment of anaerobic microorganisms by introducing sewage and sewage, and BOD, SS removal and phosphorus by the anaerobic microorganisms; An anoxic treatment step of introducing the sewage and the sewage into an anaerobic tank, providing a microbial growth environment through a microorganism contact medium installed therein, and removing the BOD and SS by the random microorganism and realizing a denitrification reaction; Again, the sewage and sewage are introduced into the aerobic tank to provide an aerobic microbial growth environment through the microbial contact media installed therein, and to produce concentrated sludge because the aerobic microorganism oxidizes organic substances and ingests phosphorus released from the anaerobic tank. We propose a biological treatment apparatus for sewage and sewage, including aerobic treatment, and a biological treatment method for sewage and sewage using the same.
