    Abstract: PURPOSE: Provided is a municipal wastewater treatment apparatus and process with continuous feed and cyclic aeration which shows high removal efficiency of organic and nutrition. CONSTITUTION: The apparatus comprises an intermittent aeration tank(2); a microbe control tank(5) which is installed inside the intermittent aeration tank to generate activated soil microbes during aerobic phase; a continuous aeration tank(3) for secondary removal of residual organics which are not decomposed in the intermittent aeration tank; a settling tank(4) for solid/liquid separation; a sludge return line(13) which returns settled sludge from the settling tank to the intermittent aeration tank; a waste sludge line(14) which transfers residual sludge from the settling tank to a sludge retention tank(6); and a supernatant return line which supplies supernatant from the sludge retention tank to the intermittent aeration tank.
