位置に取付けられ、トラフ内の水面高を堰高以下
に抑える許容流量を有する排水系と、その排水系
を導通もしくは遮断する排水系弁とを具備するこ
とを特徴とする傾斜板沈降装置。 A sedimentation tank that purifies contaminants in flowing water by settling them on the inclined plate surface, an outflow tank into which the treated water processed in the sedimentation tank flows, and the supernatant water of the outflow tank is collected and discharged to the treated water system. In an inclined plate sedimentation device comprising a trough (water collection pipe), a weir partially partitions the water outlet from the trough to the treated water system, and a weir is installed at a low position of the trough to keep the water surface height in the trough below the weir height. What is claimed is: 1. An inclined plate sedimentation device comprising: a drainage system having an allowable flow rate suppressed to 100%, and a drainage system valve that conducts or shuts off the drainage system.
