The problem of pollution from incipient rainfall has raised a high level of concern. However, in the early stage of rainfall, a large amount of polluting gases in the air, such as acid gases, automobile exhaust gas, factory exhaust gas and the like, are dissolved in rainwater, and after the rainwater falls to the ground, the rainwater in the early stage contains a large amount of pollutants, such as organic matters, pathogens, heavy metals, grease, suspended solids and the like, due to the fact that asphalt felt roofs, asphalt concrete roads, construction sites and the like are washed, so that the pollution degree of the rainwater in the early stage is high and generally exceeds the pollution degree of common urban sewage. If the early-stage rainwater is directly discharged into a natural bearing water body, the water body is seriously polluted.
The urban sewage intercepting well is an important auxiliary structure in a combined pipeline, and has the main function of intercepting urban drought sewage and initial rainwater into a sewage intercepting pipe so as to prevent urban water from being more seriously polluted. The sewage intercepting well needs to ensure that the intercepted water quantity is as constant as possible in rainy season so as to avoid increasing the water quantity load of the urban sewage treatment plant; and ensuring that the rainwater in the confluence pipeline is smoothly discharged within the designed flow range.
At present, the urban sewage catch basin is built in front of a river mouth of a confluence pipeline, and a regulation and storage tank is arranged at the tail end of a rainwater drainage pipe and canal system, so that initial rainwater is collected and is lifted by a water pump to be delivered to a sewage treatment plant. The large-scale investment is high, the interception efficiency of initial rainwater is very low, and the flow load of the sewage plant is increased in a short time.
