PURPOSE:To improve efficiency of separating work of green night soil by crushing foreign matters in night soil with a bucket pump, loading the crushed green night soil on a net conveyer belt evenly by the effect of meandering of the belt and separating urine with a rotary mangle roller. CONSTITUTION:A bucket pump C is connected to a storage tank 3 for green night soil and the green night soil is pumped up wherein said bucket pump C crushes a mixture of green night soil sucked by revolution of impellers with discoidal stationary blade having many suction holes and rotary blades sliding while contacting with the stationary blades. The pumped up green night soil is poured on the beginning part of driving of an endless net belt conveyer b moving in the horizontal direction. While conveying the green night soil on the conveyer b, the night soil is pressed as it is with a rotary mangle roller 5 to squeeze to separate green urine, which is dropped through the mesh of the net of the conveyer b and collected in a collecting tank below the conveyer b. At the same time, solid green faces freed of the urine is scraped and accumulated in the lower side part. Horizontal meandering of the green night soil on the conveyer b is controlled by shifting the direction of driving of the conveyer b.
