摘要:
To provide an inexpensive wastewater treatment method which facilitates downsizing of tanks and requires less withdrawal of an excessive sludge, the use is made of an aeration tank 1 in which wastewater is contacted with a particulate carrier under an aerobic condition, and a total oxidization tank 3 in which the volume of a sludge generated in the aeration tank 1 is reduced under an aerobic condition, a coefficient of self-oxidization of the sludge flowing into the total oxidization tank 3 is set to 0.05 (per day), and the method includes a step of adding a coagulant to the total oxidization tank 3 for the purpose of improving the solid-liquid separating characteristic of the sludge within the total oxidization tank.
