Description
Technical field
The present invention relates to technical field of sewage, more particularly, to a kind of municipal rainwater storage system.
Background technique
China city is mostly hard surfacing at present, and the precipitation in city is most of to be all discharged city by municipal drainage pipeline,
And rainfall intensity it is very big when, the drainage efficiency of municipal drainage pipe network may be far from satisfying requirement, be easy to cause road surface
Ponding is had inconvenient traffic and security risk, simultaneously as city, which is completely discharged, in precipitation enters river, freshwater resources cause to waste, city
Area's underground water cannot be fed, and urban ecological environment is fragile.
Existing conventional method is that concave herbaceous field is arranged in road surface two sides, and concave herbaceous field is a kind of elevation lower than surrounding
The public lawn on road surface, also referred to as Low elevation greenbelt, theory are to accept and store rainwater using recessed open space, have supplement
Underground water, regulated flow and flood detention, and the effect of abatement runoff pollution, but in general, Low elevation greenbelt has recessed depth
It is certain to require, and how unmodified its soil property is, when large-area applications, vulnerable to the influence of the conditions such as landform, causes reality
The volume of regulating and storing on border is lower.
Therefore, it is necessary to break the municipal water treatment systems to drain as main means, urban precipitation is set to penetrate into as far as possible
Underground, builds sponge city, one of them important urgent problem to be solved is how that quickly rainwater-collecting gets up simultaneously
It is transported to specified collection water spot, and then is uniformly filtered and water treatment.
