TREATMENT FACILITY FOR EARLY RAINFALL USING WATER RETENTION AND ITS METHOD

摘要

Purpose a: facility, a water house of detention and a kind of method are used for handling, it is used to form identical initial rainwater, it is arranged to that suspended materials is prevented to be introduced into the water house of detention with the fine foreign materials for being contained in initial rainwater, passes through and eliminate suspended materials and fine foreign materials in a pretreatment facility. Construction a: facility, for handling the initial rainwater for using a water house of detention, including a rain pipe (50), pretreatment facility (100), a water collect facility (200), a deposition facility (300), a water journey (400), a water draining facility (600) and an overflow path (500). Rainwater is collected and is flown along rain pipe. Facility is pre-processed to collect and from initial Rain-removing impurity. Initial rainwater is collected from pretreatment facility in water collect facility. Deposition facility precipitates foreign materials and sludge from initial rainwater. It flows and drains through water draining facility along dampening journey from the initial rainwater of deposition facility. The overflow path guide rainwater for crossing flight of water draining facility.
