Description

Technical Field

[0001] The present invention relates to a process for intelligently collecting initial rainwater at the source, and specifically to a process that can timely, accurately and efficiently intercept initial rainwater at the source to avoid environmental pollution caused by the initial rainwater being discharged into a receiving water body, and belongs to the field of environmental protection. Background Art

[0002] The collection and treatment of initial rainwater in my country is still in its early stages. Since there are currently no complete initial rainwater collection facilities in the country, initial rainwater is often discharged directly into surface water bodies, causing a certain degree of pollution to the water environment.

[0003] At present, China mainly adopts interception wells and sets up initial rainwater storage tanks at the end of the pipe network system to collect initial rainwater. Although it controls runoff pollution to a certain extent, it is difficult to accurately control the amount of initial rainwater according to design requirements, which increases the amount of treated water in the sewage treatment plant and has a great impact on the treatment process of the sewage treatment plant. At the same time, when the catchment area is large, the initial rain collection rate is low.

[0004] How to collect initial rainwater accurately and efficiently is a major problem that needs to be solved in order to control runoff pollution. Summary of the invention

[0005] The purpose of the present invention is to provide a process that can intercept initial rainwater in a timely, accurate and efficient manner at the source to avoid environmental pollution caused by the discharge of initial rainwater into receiving water bodies; and can also be combined with smart water services to achieve regional and batch discharge of initial rainwater to reduce the impact of initial rainwater discharge on sewage treatment plants.

[0007] The initial rainwater passes through the grid to remove larger floating objects and then enters the initial rain pool in the initial rain collection device. After the initial rain pool is full, the later clean rainwater is discharged into the rainwater inspection well through the clean rain pool rainwater connecting pipe. The initial rainwater is temporarily stored in the initial rain pool. After the rainfall is over, the regional control center controls the electric gate valves to open in sequence, and the initial rain stored in the initial rain pool is discharged into the sewage inspection well through the initial rain drain pipe, and finally enters the sewage treatment plant through the sewage pipe for treatment.

[0008] Furthermore, a rainwater grate is arranged above the rainwater collecting device, and a grid is arranged at the entrance of the rainwater collecting device. The grid is detachable, and the effective water-passing section A of the grid should not be smaller than the water-passing section A1 of the rainwater grate, that is, A≥A1 should be satisfied.

[0009] Furthermore, the detachable arch spoiler between the clean rain pool and the primary rain pool is an arch structure with a high middle and low edges, and a plurality of water holes are evenly arranged on the edges.

[0010] Furthermore, 6 to 10 water holes are evenly arranged on the edge of the detachable arched spoiler, and the diameter of the water holes is 40 to 60 mm.

[0011] Furthermore, the distance between the top of the rainwater connecting pipe in the rainwater clean pool and the top of the rainwater collecting device is 600-800 mm, and the distance between the bottom of the spoiler and the bottom of the rainwater connecting pipe should be 80-120 mm.

[0012] Furthermore, the volume V of the initial rain pool should not be less than the initial rainwater volume V1 of the runoff generated by the initial rainwater required to be intercepted within the service area of ​​the device.

[0013] Furthermore, the electric gate valve can be combined with the surrounding lighting system and powered by a solar panel or wind power generation combined power supply system, which is composed of a solar panel, a wind power generation device, a power controller, and a battery.
