Description

Rainwater Resources treatment process
Technical field
The present invention relates to a kind of rainwater-collecting treatment process, be specifically related to a kind of Rainwater Resources treatment process.
Background technology
For a long time, no matter be the public infrastructure development such as housing development or road, square, network of underground, mostly adopt steel concrete to harden, revolutionize the original ecology in earth's surface, increase rainfall runoff, cause rainwater resource to run off, urban ecological system is disorderly, and geological disaster happens occasionally, exacerbate urban waterlogging, haze and heat island effect, once rain for a long time, the rainwater if sewer can not in time, successfully be drained, just there will be serious urban waterlogging.
In order to alleviate Urban Water Environment problem, construction sponge city is a desirable selection.Sponge city refers to as sponge; water suction when raining, retaining, infiltration, water purification; when needing, the water stored discharged and be used; combine with natural way and artificial measures; under the prerequisite of draining flood safety; realize the accumulation of rainwater in city area, infiltration, purification to greatest extent, promote utilization and the ecological environmental protection of rainwater resource.
CN104532938A (date of publication on 04 22nd, 2015) discloses a kind of rainwater accumulation system, take community as unit, comprise the outdoor greening system that building roof builds, multiple ecological filter that Around Buildings is arranged and 1-2 landscape reservoir, the other ecological grass trench system arranged of parking lot, community, square and community's road.The feature of this rainwater accumulation system: by building greening system at building roof, ground arranges rainwater-collecting tank, ecological filter, ecological grass trench system etc., and it is main for below the discharge regime of rainwater being oozed, covers underground water.
Although above-mentioned rainwater accumulation system of the prior art can meet certain needs, but still there is certain defect in it: such as, its object just allow rainwater infiltration, covering underground, the problem of the just infiltration solved, can not synchronously realize rain water purification and utilization, such as, rinse the clean utilizations such as vehicle, greening irrigation, toilet flushing.
Therefore, exist for rainwater-collecting treatment process and treatment system and further improve and optimize demand, this is not only city managers' problem in the urgent need to address, especially the power that is accomplished of the present invention and starting point place.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art exists, the present inventor after having carried out a large amount of further investigations, thus completes the present invention.
The present invention is achieved through the following technical solutions, and a kind of Rainwater Resources treatment process, comprises the following steps:
Step one, filters intercepting pollution for rainwater;
Step 2, abandoned stream filters;
Step 3, charge for remittance well precipitates: rainwater is formed and precipitates and adopt dredge pump precipitation to be discharged in charge for remittance well;
Step 4, enters reservoir from the rainwater of charge for remittance well delivery port outflow and stores;
Step 5, adopts strainer to filter;
Step 6, clear water reserviors store.
Preferably, further comprising the steps of between step 4 and step 5: a part rainwater through back fill course, macadam, geotextiles permeable formation and coarse sand bed course filter, under ooze after, unnecessary rainwater enters reservoir through infiltration well and osmos tube and stores, but also some rainwater through back fill course, macadam, geotextiles permeable formation and coarse sand bed course filter, under ooze after, unnecessary rainwater enters reservoir through osmosis module and osmos tube and stores.
Preferably, in step 5, first add after Water purification medicament is flocculated and filter again; Preferred, described Water purification medicament adds described strainer by pipe-line mixer.
Preferably, the clear water in described clear water reserviors is confessed by adopting clear water supply-water pump by described clear water reserviors; Preferred, the clear water that described clear water supply-water pump is confessed is discharged to after first adopting apparatus for ultraviolet disinfection to carry out disinfection again and uses water spot.
Compared with prior art, beneficial effect of the present invention is as follows: the present invention does not achieve storing of rainwater by means of only reservoir, reduce the pressure of rainwater earth's surface flow and municipal Storm Sewer Network, and filtered by intercepting pollution for rainwater, abandoned stream filters, the charge for remittance precipitation of charge for remittance well, the steps such as filtration achieve the purified treatment of rainwater, clean water after process is stored in clear water reserviors and facilitates later stage clean utilization, achieve " storing of rainwater, only, with " etc. the resultant effect of aspect, again in conjunction with after rainwater penetration system, more can realize " oozing, stagnant, store, only, with " etc. the resultant effect of aspect, thus be conducive to the valuable source that rainwater becomes urban sustainable development.
