Description

A kind of rainwater purification structure for sponge urban construction
Technical field
It the utility model is related to urban rainwater reutilization technology field, and in particular to a kind of rain for sponge urban construction Water warfare structure.
Background technology
In recent years, meet rain must flood be increasingly becoming the chronic illness in many cities.Therefore, to not " seeing sea in city ", not It is so simple only to carry out pipeline dilatation.All using fast row's pattern, rainwater falls on hardened ground can only be from current many cities Concentrate fast row in pipeline, heavy showers is once great pipeline is all not enough feeling to repair, and this pattern allows 70% in city Rainwater lost in vain.
Sponge city, refers to that city can be as sponge, it is adapting to environmental change and reply natural calamity etc. With good " elasticity ", for example, can absorb water when raining, water storage, infiltration, water purification, and by the water stored " release " when needing Out and it is used.Therefore, sponge city realizes rain to greatest extent on the premise of municipal drainage prevention waterlogging safety is ensured Water so as to promote recycling and the ecological environmental protection of rainwater resource, and then is realized in the accumulation, infiltration and purification of urban area The high standard and new demand that country proposes Urban Storm Flood management.
If leaving rather than draining most of rainwater, product of the rainwater in urban area can be realized to greatest extent Deposit, permeate and purify, promote the utilization and ecological environmental protection of rainwater resource.That is, ' sponge city ' be expected to will be original A large amount of water for draining into pipe duct end by absorbing, saving, the link such as permeate and digest, become in advance and crack having for ' meeting rain flooded ' Effect approach, rather than by repairing big drainpipe.
Rainwater purification refers to after rainwater is collected according to demand, and after carrying out purified treatment to the rainwater of collection Reach the system met using standard.The rainwater of collection is roughly divided into two classes, roof rain water and rainwater on road surface, it is contemplated that at present I State's atmosphere pollution situation is more serious, and the rain and impurity being collected into is more, and contamination sources are complicated.
At present, in sponge urban construction, it is too poor that the recycling water that is handled by rainwater purification still has water quality The problem of, it so can not only meet the use of city system well, cause the rainwater comprehensive utilization rate of collection low, because This, also can not meet theory and the requirement of sponge urban construction and ecological environmental protection.
