Flow distribution slow release rainwater flow discarding device

Abstract

The invention discloses a flow distribution slow release rainwater flow discarding device, which comprises a water inlet, a flow discarding turning plate, a filtering layer, a clear water layer and aflow discarding layer, wherein the clear water layer is positioned above the flow discarding layer and is positioned above the filtering layer; the clear water layer and the flow discarding layer areisolated; the filtering layer communicates with the clear water layer; a rainwater reuse water inlet and a flow discarding water inlet are formed in the water inlet part; the rainwater reuse water inlet is positioned above the flow discarding water inlet; the flow discarding turning plate is suspended between the rainwater reuse water inlet and the flow discarding water inlet; the flow discardingwater inlet can be opened or closed by the flow discarding turning plate; the rainwater reuse water inlet communicates with the filtering layer and the clear water layer; the flow discarding water inlet communicates with the flow discarding layer; a water outlet is formed in the clear water layer; and a flow discarding opening is formed in the flow discarding layer. The structure is simple; the manufacturing cost is low; the automatic operation of rainwater flow discarding and collection can be realized only through the device per se; and the rainwater can be effectively managed and controlled.

Description

Technical field [0001] The invention relates to the technical field of rainwater abandonment, and more specifically, to a diversion slow-release rainwater abandonment device. Background technique [0002] As a clean water source, rainwater plays an important role in the environment and water resources utilization. The initial rainwater is mixed with a large number of pollutants, sediments and impurities. Therefore, the initial rainwater should be discarded and discharged to collect the clean rainwater in the middle and later stages. At the same time, the impurities in the rainwater are filtered out to ensure the normal operation of the later water storage system and ensure the safety of drainage. The clean rainwater after treatment and evaporation can reach the standard of drinking water. [0003] Traditional rainwater collection uses initial rainwater abandonment devices, interception wells, diversion wells, initial rainwater filtration, grit tanks, etc. The disadvantages are larg...
