Under background, how to collect the valuable rainwater resource of development and utilization, how to allow more " drinking " rainwater " quenching one's thirst " in city, become one it is important
Project.
It is well known that municipal rainwater is generally divided into initial rainwater and later period rainwater, initial stage rain in terms of the variation of water quality
Water is due to containing ground dirt (chemical powder fallen in the gasoline of automobile water clock, transport or liquid, silt, tiny suspension
Object, fallen leaves, house refuse etc.) make concentration of suspension higher, water quality is poor, with the lasting progress of rainfall, above-mentioned ground
Dirt is fewer and fewer under the cleansing of rainwater, and rainwater turbidity is lower and lower therewith, and water quality is also improving and tending towards stability.
Municipal administration rain collector in the prior art, for the rainwater typically directly abandoned stream at initial stage, however in arid rain
In water less season, above-mentioned processing mode cannot efficiently use valuable rainwater resource, not enough science environmental protection.In the prior art
Another common processing mode is that filter device is arranged in rain collector, in this way for the rainwater at initial stage (including
The rainwater in later period) it is able to carry out preliminary purification, it is discharged into water tank is stored later.However, aforesaid way is only pair
Initial rainwater is simply purified, and purified initial rainwater quality is not still up to standard, and is not separated with later period rainwater
Store so that later period rainwater is also contaminated, in this way using when need to be purified again, increase use cost.This
