WASTE WATER TREATMENT EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide waste water treatment equipment that can be miniaturized and can remove solid material and treat water even with small volume. SOLUTION: This waste water treatment equipment is equipped with a solid- liquid separator 10 to precipitate and separate solid material in waste water of a disposer, a treating tank 20 decompose the organic substance in waste water discharged from the solid-liquid separator 10 by microbe, a sedimentation/ separation tank 30 to precipitate and separate sludge generated in the treating tank 20, a return means (a sludge return pipe 31 and a return pump 64) to return sludge precipitated in the sedimentation/separation tank 30 to the solid- liquid separator 10, and a filter part 14 to prevent solid from effluence at the outflow part (outlet 15) to the treating tank 20 from the solid-liquid separator 10.
