GRANULATION METHOD BY AEROBIC BIOLOGICAL TREATMENT OF ORGANIC WASTE WATER AND AEROBIC BIOLOGICAL TREATMENT OF ORGANIC WASTE WATER

摘要

PURPOSE:To produce granular bacterial body with good precipitation property by a simple method and treat organic waste water efficiently with no need of special apparatus which cost much. CONSTITUTION:Organic waste water or treatment liquid 5, that is the organic waste water to which microbe source is added is poured in an aeration tank 1 and air is sent to it through an air sending pipe 4. The air comes out of a ball filter 3 and generates whirling flow in the treatment liquid 5. By keeping this state, granular bacterial body is produced based on self-coagulation of the microbe in the organic waste water or added microbe source and at the same time waste water treatment is carried out. Also, organic waste water treatment is carried out using the granular bacterial body.
