Problems solved by technology

[0005] In addition, during the rainfall process, the middle and late rainwater is generally relatively clean and can be directly discharged to natural water bodies. However, due to the mixing of initial rain, the middle and late rainwater in the rainwater main pipe is polluted, and it also needs to be treated before it can be discharged.
But the existing drainage system does not pay attention to this problem

Embodiment 1

[0046] The structure of a road rainwater diversion treatment system in this embodiment is as follows: figure 1 As shown, the system includes a rainwater main pipe C and a sewage main pipe D on the municipal road R. The end of the rainwater main pipe C is a natural water body, and the end of the sewage main pipe D is a sewage treatment plant. The rainwater The main pipe C is segmented according to the length of 500-800m, and a diversion well 1 is set on each section of the rainwater main pipe C. The diversion well 1 has two water outlets, the first outlet is connected to the rainwater main pipe C, the second outlet is connected to the sewage main pipe D through the interceptor 2, and a lower opening weir gate is set in front of the first water outlet in the diversion well 1-1, an upward-opening gate 1-2 is set before the second water outlet in the diversion well.

Abstract

The invention relates to a road rainwater diversion treatment system and a control method thereof. The system comprises a rainwater main pipe and a sewage main pipe, which are arranged on a municipalroad; the tail end of the rainwater main pipe communicates with a natural water body; the tail end of the sewage main pipe communicates with a sewage treatment plant; the road rainwater diversion treatment system is characterized in that the rainwater main pipe is segmented, and each segment of the rainwater main pipe is provided with a diversion device; one of water outlets of each diversion device is connected to the rainwater main pipe, and another water outlet is connected to an intercepting pipe inlet; and an intercepting pipe outlet is connected to the sewage main pipe or the rainwater main pipe. With the application of the system provided by the invention, initial rainwater entering the rainwater main pipe can undergo segmental treatment; on each segment of the rainwater main pipe,the initial rainwater is divided into the sewage main pipe, and rainwater of middle and later periods is directly discharged into the natural water body; therefore, the initial rainwater and the rainwater of middle and later periods can be separated more precisely, and the circumstance that the natural water body is polluted by the initial rainwater in the rainwater main pipe is prevented.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a road rainwater diversion treatment system and a control method thereof. Background technique [0002] With the acceleration of urbanization, the impermeable area on the ground has increased significantly, and pollutants have gradually accumulated on these impermeable ground. When it rains, the rainwater washes the ground and the pollutants are washed into the rainwater runoff system to form rainwater runoff pollution. Rainwater runoff pollution is a kind of diffuse pollution. Pollutants enter natural water bodies and cause water pollution. The pollutants include particulate matter, organic matter, heavy metals and other toxic and harmful substances. Therefore, the process of urbanization and industrialization has led to increasingly serious water crisis and rain and flood hazards. [0003] With the aggravation of water source crisis and rain and flood damage, it has ...
