Flow dividing storage adjusting type gutter inlet device with pretreating function

Abstract

The invention relates to a flow dividing storage adjusting type gutter inlet device with a pretreating function. The device comprises a well cavity and a water permeating well cover covering an opening at the upper end of the well cavity, a water inlet chamber, a pretreating chamber, a first water filling chamber and a storage adjusting chamber are formed in the well cavity, the water inlet chamber is arranged under the water permeating well cover, and the pretreating chamber is communicated with the water inlet chamber; a grating used for blocking dregs in rainwater is arranged on the communication portion of the pretreating chamber and the water inlet chamber, a sedimentation assembly is arranged in the pretreating chamber, and the pretreating chamber is communicated with the first waterfilling chamber; the storage adjusting chamber is arranged under and communicated with the first water filling chamber, and a baffle plate mechanism is arranged at the bottom of the first water filling chamber. According to the gutter inlet device, the rainwater can be automatically treated through the grating and the sedimentation assembly, rainwater of different accumulated rainfall capacitiesis subjected to flow dividing and storage adjusting in the raining process through the first water filling chamber and the storage adjusting chamber so as to conveniently convey the rainwater to subsequent treatment facilities for sorting treatment after raining, project benefits of all the treatment facilities are fully produced, and the water quality of downstream receiving water is further protected.

Description

technical field [0001] The invention relates to the technical field of municipal drainage supporting facilities, in particular to a diversion regulation and storage type gully device with a pretreatment function. Background technique [0002] When rainwater falls from the air to the ground until it flows into the rainwater collection facilities on the road, it will often take away pollutants such as dust in the air and ground muck. According to previous studies, in the whole process of a rainfall, with the rainfall With the increase of time, the total rainfall is constantly increasing, but with the continuous washing and carrying effect of rainwater, the pollutants in the air and on the ground are constantly decreasing, and the corresponding concentration of pollutants in rainwater is constantly increasing. Reduced. The traditional urban rainwater pipeline system collects rainwater on the road surface through the rainwater collection facility at the beginning - the rainwate...

AI Technical Summary

Problems solved by technology

[0003] (1) The rainwater on the road surface is not pretreated, and the suspended solids contained in the rainwater are likely to be deposited in the rainwater main pipe or terminal treatment facilities to affect its operating efficiency;

[0004] (2) The pavement rainwater is not diverted according to different accumulated rainfall, which makes it impossible for the downstream rainwater treatment facilities to classify and treat road rainwater with different pollution levels, thereby affecting the treatment effect and causing the downstream receiving water body to be polluted;

[0005] (3) The rainwater on the road surface is directly transported to the downstream rainwater main pipe without any regulation and storage, and the function of regulation, storage and peak shaving has not been played. When the rainfall is large, each gully device directly discharges the road surface rainwater, which may easily lead to the discharge of rainwater from the downstream rainwater main pipe. The superimposed amount of water affects its drainage capacity, making its drainage poor, resulting in water accumulation on the road
