Abstract

PURPOSE: A simplified and less-equipped sedimentation tank with shortened sludge return route is provided by inserting, in mixed aerobic-anaerobic treatment, an anaerobic tank in which returned sludge is treated by controlled heat and aeration quantity so that the degree of anaerobic operation is regulated.
CONSTITUTION: A mixed aerobic-anaerobic treatment tank is installed either upstream or downstream, or both of an aerobic tank so that water to be treated is subjected to a mixed aerobic-anaerobic operation. Further, the process is added with an anaerobic tank in which returned sludge is treated by controlled heat and aeration quantity so that the degree of anaerobic operation is regulated. This eliminates or simplifies the sedimentation tank at each terminal of intermediate treatment, thus resulting in reduced route for returned sludge and additional effect of improved odor.
