Abstract

The invention provides an industrial sewage treatment system and an industrial sewage treatment method, which solve the problems that the existing industrial sewage is difficult to treat and not desirable for phosphorous and nitrogen removal effect and the like. The sewage treatment method comprises the process steps as follows: (1) solid sundry separation; (2) anaerobic hydrolysis; (3) oxidation ditch biochemistry treatment process including flora culture in activated sludge, biochemistry nitrogen and phosphorous removal; (4) secondary settling; (5) coagulation and phosphorous removal; (6) flocculation and disinfection; and (7) removal of suspended solid and phosphorous.

Description

technical field [0001] The invention relates to a sewage treatment system and a treatment method thereof, in particular to a sewage treatment system and a sewage treatment method for industrial wastewater. Background technique [0002] Worldwide, especially in developing countries, industrial sewage discharged from various industrial production processes has caused serious harm to the environment, brought heavy economic burdens to governments and enterprises, and environmental problems It has attracted the attention of the government. [0003] In sewage treatment, organic matter is mainly removed, and phosphorus and nitrogen are removed at the same time. At present, there are many methods for treating this kind of sewage containing organic matter and phosphorus, mainly including anaerobic-aerobic method, anaerobic-anoxic-aerobic and Activated sludge process, and sequencing batch activated sludge process. The most widely used is the anaerobic-anoxic-aerobic biochemical phos...
