Description

Technical Field

[0001] The present invention relates to the technical field of initial rainwater pollution treatment, and in particular to an integrated initial rainwater process treatment structure and method. Background Art

[0002] With the continuous improvement of urbanization, the impervious surface area increases, the rainwater runoff increases, and the non-point source pollutants washed into the water body also increase accordingly. Initial rainwater is the rainwater in the initial stage of rainwater runoff, which has a strong impact. At this stage, the concentration of runoff pollutants is significantly higher than that in the later stage. There is a peak concentration of pollutants, which is the main reason for the decline in the water environment quality of the receiving water body. Initial rainwater treatment can be divided into three categories: source reduction, process control and end-of-pipe treatment. Source treatment is to change the runoff conditions, increase the rainfall infiltration, and treat the rainwater before it enters the pipeline system. Process treatment refers to the purification of rainwater during the transmission of rainwater runoff. End-of-pipe treatment is to use technology to effectively remove pollutants before the initial rainwater is discharged into the environment to reduce pollution to the water environment.

[0003] The existing integrated initial rainwater process management structure generally adopts the end-of-pipe treatment method to purify the polluted water body, and there are fewer process management methods. The initial rainwater filtration device on the market only treats solid pollutants, and there is a blockage phenomenon after long-term use, which leads to a decrease in water quantity and quality.

[0004] The existing integrated initial rainwater process treatment structure only treats solid pollutants, which will cause blockage after long-term use, resulting in a decrease in water quantity and quality. The integrated initial rainwater process treatment structure can remove solid pollutants and soluble pollutants at the same time, and solve the blockage problem caused by long-term use. The integrated initial rainwater process treatment system can prevent pollutants carried in the initial rainwater from entering the water body and causing water pollution. Summary of the invention

[0005] In order to overcome the existing integrated initial rainwater process management structure, the end-of-pipe management method is generally adopted to purify the polluted water body. There are fewer process management methods. The initial rainwater filtration device on the market only treats solid pollutants, and there is a blockage phenomenon after long-term use, which leads to the problem of reduced water quantity and water quality.
