Description
Technical Field
The utility model relates to an outdoor drainage field, concretely relates to initial stage rainwater sump pit.
Background
The initial rain water is, as the name suggests, rain water at the initial stage of rainfall. Generally, the rainfall is 10-15mm, and the surface runoff precipitation is formed. In the early stage of rainfall, a large amount of acid gases, automobile exhaust, factory waste gas and other pollutant gases in the air are dissolved in the rainwater, and after the rainwater falls to the ground, the rainwater contains a large amount of organic matters, pathogens, heavy metals, grease, suspended solids and other pollutants in the rainwater in the early stage due to the fact that asphalt felt roofs, ground garbage, 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 initial rainwater is directly drained into the rainwater pipe network and enters the natural bearing water body, the water quality and the water environment of the water body are polluted to a certain degree.
Natural rainwater is a precious water resource and must be reasonably utilized, and non-point source pollution caused by rainwater runoff is also very serious. A large number of existing research results show that: the urban rainwater runoff water quality change condition is analyzed and obtained, the general trend that all pollutants change along with the rainfall process is that the rainwater initial runoff pollutant concentration is very high, the pollutant concentration gradually decreases and tends to be stable along with the prolonged rainfall, about 70% of pollutants concentrate in the initial scouring effect, and rainwater with a low pollution degree in the middle and later periods (the rainfall is more than 10 mm) can be directly discharged into a natural bearing water body or underground after suspended matters and solid particle impurities in the rainwater are intercepted by the intercepting and hanging basket, so that underground water resources are supplemented, the urban drainage pressure is reduced, and the natural water body environment of people is effectively protected.
The urban rainwater pipe network system generally comprises a rainwater port, a connecting pipe, an inspection well, a main pipe and a water outlet. Rainwater passes through the rainwater inlet → the connecting pipe → the inspection well → the dry pipe → the water outlet → the water receiving body of the river and lake, so that the respective collection and treatment of initial rainwater and rainwater in middle and later stages cannot be realized, rainfall runoff completely enters the urban rainwater pipe network, the pollution of the water receiving body of the river and lake exceeds the standard, the water environment deteriorates, and the water functional area does not reach the standard.
