Domestic sewage mainly comes from wastewater produced in daily life and diet living of people, is discharged through a sewer pipeline or a sewage pipeline and finally flows into a sewage treatment plant for treatment. For rainwater, the initial rain (rainwater in the early stage of rainfall) carries more pollutants, such as heavy metal substances carried by a washed road surface, pollutants carried from the atmosphere and the like, if the pollutants are directly discharged into a river water body, toxic and harmful substances such as heavy metals and the like are continuously enriched by organisms, so that the biological environment of the water body is greatly influenced, and the harmful effects on the health of urban residents are also caused, so that the sewage generated by the washing of the initial rain on the ground cannot be directly discharged into a river channel. When the ground is washed cleanly by rainwater, the rainwater is slightly polluted, and can be directly discharged into urban inland rivers after being shunted, and can be used as natural landscape water after being naturally precipitated and can also be used as urban municipal water for spraying roads, so that the rainwater flows into rivers after being purified and buffered, and the use benefit of surface water can be improved; meanwhile, polluted rainwater is discharged into a sewage pipe and is treated by a sewage treatment plant, so that sewage is recycled.
However, the existing rainwater drainage mode can cause that a sewage treatment plant cannot timely judge the condition that rainwater is polluted, possibly causing that the sewage treatment plant excessively treats rainwater or fails to treat all polluted rainwater, causing the condition that the sewage treatment plant runs under high load or treats insufficient sewage, and when the sewage treatment plant cannot treat all polluted rainwater, the polluted rainwater can cause water pollution when being discharged into a river.
Therefore, there is a need for a new rain and sewage separation system.
