CLEANING DEVICE FOR ORGANIC SEWAGE

摘要

PURPOSE:To easily propagate microorganisms having activity at a high temp. by lowering biochemical treating tanks and a cleaned water storage tank into the ground and submerging a blower to feed air to the former into the cleaned water of the latter. CONSTITUTION:The biochemical treating tanks 11a to 11f and cleaned water storage tank 15 of this cleaning device 1 are lowered into the ground. The ground temp. is thereby taken into the mixed sewage Wm and cleaned water Wx in both tanks. The temp. change of the mixed sewage Wm and cleaned water Wx in both tanks is, therefore, small throughout the year like the temp. of, for example, the ground water does not change largely throughout the year. The mixed sewage Wm in the biochemical treating tanks 11a to 11f is directly heated up by the ground temp. and a part of the cleaned water Wx heated up by the ground temp. in the cleaned water storage tank 15 is circulated to livestock sewage Wa introduced into into a mixing tank 8 and is thereby mixed therewith.
