Novel rainwater shunting device

Technical Field

The utility model relates to a rainwater reposition of redundant personnel technical field specifically indicates a novel rainwater reposition of redundant personnel device.

Background

At present, the shortage of urban water resources becomes a global problem, for example, rainwater can be utilized to relieve the pressure of water use to a certain extent, but the rainwater contains a large amount of pollutants, especially the initial rainwater is poor in water quality. The initial rainwater washes the earth surface and the roof and carries a large amount of pollutants, so the pollution degree of the initial rainwater is serious, the treatment cost is relatively high, and the initial rainwater is abandoned from the economic point of view. In the early stage of rainfall, rainwater dissolves a large amount of polluting gases in the air, such as acid gases, automobile exhaust gases, plant exhaust gases, etc., and generally contains a certain amount of toxins affecting plant growth, which may include sulfides, salts, TDS (total dissolved solids), etc. After the rainwater falls to the ground, the rainwater in the earlier 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 away, and therefore the pollution degree of the rainwater in the earlier stage is high and generally exceeds the pollution degree of common urban sewage. If the early-stage rainwater is directly used for a rainwater recycling system, the treatment process is complex, the operation cost is high, and therefore the early-stage rainwater must be subjected to flow discarding treatment. Initial rainwater runoff may remove a majority of the contaminants in the runoff, including fine or dissolved contaminants. Therefore, the method is an effective water quality control technology.

At present, the initial rainwater drainage method at home and abroad mainly comprises the following steps: the system comprises a preferential flow method discarding pool, a switching type or small pipe discarding well, a cyclone separation type initial rain discarding device and an automatic turning plate type initial rain separator. The method has the problems of low collection efficiency, difficult random rainfall operation control and the like.
