Rainwater-collecting hierarchic purification treatment system and method

Abstract

The invention provides a rainwater-collecting hierarchic purification treatment method and a rainwater-collecting hierarchic purification treatment system. Through the rainwater-collecting hierarchicpurification treatment method and the rainwater-collecting hierarchic purification treatment system, control can be performed according to different conditions at different times of water accumulationduring raining, so that excessive impurities in the early stage are avoided from entering primary and secondary filtering devices to increase the burden of subsequent purification; the situation of rainwater is monitored according to increase of the rainwater per unit time, so that the inflow situation is monitored more scientifically and quantitatively. A right-angled filtering device in a primary filtering chamber can secondarily filter water entering the primary filtering chamber to enhance the filtering effect, and then the water flows out from a right water outlet to enter a secondary filtering chamber, so that the filtering need of cleaner water is met.

Description

technical field [0001] The invention relates to the field of rainwater purification treatment, in particular to a rainwater collection hierarchical purification treatment system and method. Background technique [0002] Rainwater collection and treatment can effectively use resources, such as the sponge city advocated now, make full use of the collected rainwater, through preliminary purification treatment, such as collecting on the road, enter the sewer; or flow into the green belt from the road, to The green belt is irrigated and enters the reservoir for further purification to prevent rainwater from affecting the road, and excess water will cause safety hazards. The rainwater collection and treatment methods in the prior art are relatively simple, lack of refined purification methods, and cannot meet different needs. In addition, the size of the rainfall will also affect the effect of collection and purification. The lack of monitoring and control of rainfall often makes ...

Problems solved by technology

The rainwater collection and treatment methods in the prior art are relatively simple, lack of refined purification methods, and cannot meet different needs. In addition, the size of the rainfall will also affect the effect of collection and purification. The lack of monitoring and control of rainfall often makes The purification is not thorough enough and the effect is not good
