COLLECTION MECHANISM FOR SOLID MATTER IN TREATED WATER, COLLECTION METHOD FOR SOLID MATTER IN TREATED WATER, AND WASTE WATER TREATMENT SYSTEM

摘要

To provide a collection technique for a solid matter in waste water by which cleaning is easy during operation and after operation, and sufficient solid matter recovery effect can be obtained.SOLUTION: A collection mechanism 10 for solid matter in treated water, which is a mechanism for collecting organic substance-containing water (treated water), comprises a flow channel 1 in which treated water flows, and a pile-like obstacle 5 for solid matter collection which is placed on a groove 3 of the flow channel. A bottom 2 of the flow channel is so configured as to have plural grooves 3 in a flow direction. Plural obstacles are provided in a same groove, and further, the obstacle is provided in each groove.SELECTED DRAWING: Figure 1
