Abstract
PURPOSE: To carry out aerobic biological treatment effectively, to eliminate the use of a diluting water and miniaturize an apparatus by a method wherein, in treating a high concn. waste water without diluting, a plural of many nitration tanks are arranged in parallel and a waste water is distributed, poured and treated.
CONSTITUTION: In treating a high concn. waste water such as excretion, many nitration tanks are arranged in parallel so as to form completely mixing tanks 1W5 and the high concn. waste water is distributed into respective tanks without being diluted to nitrate or aerate said waste water respectively. Thereby, a completely mixed system wherein various water qualities and substance concentrations in each tanks 1W5 are uniform in all places can be maintained. Therefore, the water quality of a treated water and the concn. in tanks are coincided and BOD, NH4-N concn. are reduced to a lower value as well as an oxygen comsunption speed is reduced to a lower value. As described above, a high concn. waste water is treated without using any treatments.
