In the rainfall process, the initial rainwater scours roofs and roads, is mixed with a large amount of dust and silt and has poor water quality, and the water is subjected to flow discarding treatment so as to be directly discharged into municipal sewage pipelines; and because the initial rainwater usually contains sundries such as leaves, silt and the like, the initial rainwater enters the diversion well and then rushes into the sundry sleeve 4 through the gap between the circular grid 42 and the sundry sleeve 4, most of the leaves are clamped on the lower surface of the circular grid under the action of self buoyancy, most of the silt falls into the bottom of the sundry sleeve 4, and the small part of the silt enters the silt settling space 3 at the bottom of the diversion well; after the precipitation stops, the sundries sleeve 4 is pulled up through the guy cable to clean sundries such as sand, leaves and the like in the sundries sleeve, and the sundries can be reused; the abandon flow controller does not need manual control, is completely controlled by a built-in PLC control program to carry out multi-point signal series monitoring control, can carry out memory processing on rainfall, pH value, rainstorm backflow and the like, and determines the opening and closing conditions of the rainwater abandon flow pipe valve 11 and the rainwater collecting pipe valve 21 through a water quality signal probe on the water quality sensor 5.

Rainwater enters the regulating reservoir after being abandoned in the initial stage, the regulating reservoir has a precipitation function, and the inflow and the outflow of the rainwater need to avoid disturbing sediments so as to avoid influencing the subsequent treatment process. The water inlet adopts submerged water inlet, the water inlet is inclined upwards or horizontal, and the effluent is pumped to the purification device through the filtering lifting pump arranged in the tank. In addition, the regulation and storage water tank is also provided with a sludge discharge device to avoid excessive precipitation.

Since rainwater contains a large amount of dust in air and forms a large amount of suspended matters in the rainwater, the particle size of the suspended matters formed by the dust is very small, and an ideal filtering effect cannot be achieved by only using a filler type filter, a coagulation reactor needs to be equipped to improve the filtering efficiency. In the coagulation process, pollutants in water are gathered by utilizing the polymerization effect of a coagulant on suspended matters; the coagulant can adopt polyaluminium chloride, the polymerization effect is obvious, the coagulant is mixed with rainwater and then enters a reactor, the medicament reacts with pollutants to generate large concrete, and the large concrete is filtered by a filter. Flocculent mass of larger diameter is formed and separated from the water by filtration means.
