NOVELTY - A municipal sewage is treated using 2 sections of anaerobic-aerobic film bioreactor, which includes pouring municipal sewage into upflow anaerobic sludge blanket (UASB) (1); controlling UASB conditions; pouring UASB-processed water into oxygen-poor reactor (9); controlling reactor conditions; pouring into aerobic reactor (10); controlling aerobic reactor conditions; and examining such that removal rate of chemical oxygen demand (COD) representing consistency of organic contaminant is above 96%, removal rate of ammonia is above 93%, and removal rate of phosphorus is above 92%.    USE - Method for treatment of municipal sewage (claimed).    ADVANTAGE - The method is capable of saving energy, because it can recycle energy during the process. The produced energy can be used to generate electricity and used as power for running concentrated solution reflux pump of the UASB. It saves the amount of reagents used in the aerobic processing stage. It has a good effect of removing organic pollutant, deoxidation, and removing phosphorus.    DETAILED DESCRIPTION - Treatment of municipal sewage using 2 sections of anaerobic-aerobic film bioreactor involves:    (A) pouring municipal sewage into UASB (1) through inletting pump (5); controlling UASB at pH 6.5-7.5 and at 22-28 degrees C; and maintaining water power for 2.5-3.5 hours and mud for 70-120 days, in which removal rate of chemical oxygen demand (COD) representing the concentration of organic contaminant is 65-75%, concentration of acetic acid yielding water is 47-75 mg/l, and gas production of methane is 0.4-0.7 m3/kg COD/day;    (B) pouring the UASB-processed water into oxygen-poor reactor (9); controlling reactor at pH 6.5-7.3 and at 22-28 degrees C; maintaining water power for 2.5-3.5 hours and mud contents in sewage at 9.5-10.4 g/l; and maintaining mud for 96-105 days;    (C) pouring the water processed by oxygen-poor reactor into aerobic reactor (10); controlling aerobic reactor at pH 6.5-7.5 and at 22-28 degrees C; maintaining water power for 5.5-6.5 hours; controlling mud contents in sewage at 9.5-10.5 g/l; maintaining mud for 100-160 days; and examining such that the removal rate COD representing concentration of organic contaminant is above 96%, the removal rate of ammonia is above 93%,e and the removal rate of phosphorus is above 92%; and sucking out recycled water from the aerobic reactor using a sucking pump (15), in which the recycled water reaches the standard after being processed.
