Biochemical process for purifying contaminated water |
摘要 |
A process for treating contaminated water containing BOD sources and nitrogen sources, which comprises supplying oxygen or oxygen-containing gas from one side of a gas-permeable membrane to grow microorganisms including aerobic bacteria and anaerobic bacteria on the other side of the gas-permeable membrane, and performing decomposition of the BOD sources and nitrification and denitrification simultaneously by the action of these microorganisms. Especially good results are obtained when a membrane composed of porous hollow fibers is used as the gas-permeable membrane.
