METHODS OF ADVANCED WASTEWATER TREATMENT

摘要

PURPOSE: An advanced sewage processing method is provided to improve removal efficiency of phosphorus and nitrogen when sewage is biochemically processed, and to prevent environmental contamination of water. CONSTITUTION: An advanced sewage processing method includes the following steps: processing inflow water with phosphorus in an anaerobic tank(100); denitrifying outflow water of the anaerobic tank in an anoxic tank(200); nitrifying and performing a dephosphorus process of the outflow water in an aerobic tank(300); precipitating the outflow water in the aerobic tank; and denitrifying the outflow water in a sulfur-based denitrification tank(500). The aerobic tank is filled with fluidized bed microbial carriers.
