Description

The abandoned stream of rainwater-collecting is with cutting dirty governing system
Technical field
The utility model belongs to sponge city technical controlling field, more particularly to a kind of abandoned stream of rainwater-collecting with cutting dirt Governing system.
Background technology
Sponge city is new generation of city storm water man- agement concept, refers to that city is adapting to environmental change and reply rainwater band Natural calamity come etc. has good " elasticity ", also referred to as " water elasticity city ".International term is " low shadow Ring exploitation storm-water system structure ".Rain when water suction, water storage, infiltration, drainage, water purification, when needing by the water stored " release " and plus To utilize.
With the development of urbanization process, pollutant accumulation so that hold a large amount of pollutant in rainwater on road surface, at some Pavement runoff research shows that, the pollutional load in 30% rainfall runoff of initial stage accounts for the 70% of whole field rainfall pollution, therefore, just The retention of phase rainwater can effectively control the next water pollution of runoff zones with processing.At present, both at home and abroad for rainwater pollution processing There is different measures, foreign countries are that rainwater is directly collected to recycling mostly, and the country is that initial rainwater is introduced directly into dirt Water treatment plant, have ignored sewage treatment plant decontamination capacity it is limited, extra sewage is unprocessed to be directly discharged into natural water.Therefore, It is necessary to carry out abandoned stream processing to rainwater early period, develop the abandoned stream that can make up these insufficient rainwater-collectings of aspect and controlled with cutting dirt Rainfall initial rainwater is branched to sewage conduct by reason system, and the rainwater of rainfall Final pollution lesser extent is retained by pretreatment The granule foreigns such as the grains of sand, rubble in water and a large amount of pollutants, multiple times of filtration, purification, it is possible to reach the mark of recycling Standard, and with the storm water conservation lawn after purification, filtering, improve the utilization rate of water resource.
Some flow abandoning apparatus of the prior art have disadvantages that, if the volume of design is excessive or the volume of design is too small, Some devices take manual operation control, are sometimes prone to fail, and some tectonic sievings are more complicated, and some costs are excessively high, and The initial rainwater residence time is long, and the granule foreigns such as the grains of sand, rubble and a large amount of pollutants easily precipitate, and easily device are caused to block up Plug is unfavorable for the normal use of device.
