Description
Technical field
The present invention relates to sponge urban construction technical field more particularly to a kind of sponge urban rainwater purification collection system and
Rainwater treatment method.
Background technology
China is the country of water resource relative shortage, and water resources ownership per capita is only the 28% of world average level.According to
It counts within 2017, China's water total amount has broken through 6100 billion cubic meters, but national water deficit is still up to billion cubic meter more than 500, closely
The different degrees of water shortage in 2/3 city.As economic society continues to develop, in the long duration from now on, the contradiction of supply and demand for the water resource will more
Add protrusion.
Urban water is the general designation of the required water of the activity such as city production, life, fire-fighting and municipal administration.City is used at present
Water is mainly realized by following methods：First, utilizing rivers and lakes, this is relatively applicable in the abundant area of rainfall resource；
Second is that exploiting groundwater, water shortage city mostly uses greatly the mode of exploiting groundwater and maintains urban water at present, many cities because
Excessive exploitation of groundwater leads to low water level decreasing, this is particularly evident in the inland city of arid；Third, sea water desalination, but due to edge
Haicheng City general precipitation is resourceful, while sea water desalination cost is higher, applies at present less.
All there is the problems in rainfall collection in China most of areas.It is dirty in the case where carrying out sewage, rainwater separate system
Water is collected by drainage pipeline, is sent to sewage disposal, and water body or recycling are discharged into；After rainfall runoff is collected by drainage pipeline,
It is discharged into water body nearby.Aesthetic due to past society thinks that city hardening is better, more seems high-end, air, improves grade, arranges simultaneously
Grid design does not catch up with urban development speed, causes, whenever rainy season, to be easy for urban waterlogging occur.Therefore rainfall pair is made good use of
In alleviate urban water and urban waterlogging problem very it is necessary to.Sponge city is new generation of city storm water man- agement concept, international
Generic term is " storm-water system structure is developed in low influence ".
The required water of the activity such as production, life, fire-fighting and municipal administration in urban water, different purposes, for water
Quality requirement it is also different therefore also different for the collection of rainfall processing.Currently, sponge urban construction is in primary rank
Section, is still not perfect the utilization of rainfall, and that there is infrastructure constructions is of high cost, maintenance cost is high, short life, while rainwater
Utilize unreasonable problem.

After rainwater drops to ground, the pollutant effects by ground are larger.For different ground, the difference of pollutant
Also larger.If it is the ground based on vegetation, then the deadwood and rotten leaf contained in rainwater is more.Due to people the quality good and the bad not
Together, also containing cigarette butt, rubbish or even the excreta of some human or animals on ground.The sponge urban rainwater purification of the present invention is collected
System 10 first passes through initial rainfall processing module 20 and the rainwater containing dirtier pollutant is discharged at the sewage network in city
Reason.This part rainwater is generally discharged by drainage pipeline in natural stream networks nearby by the prior art.This drainage pattern is easy will
Pollutant brings natural stream networks into, to cause environmental pollution.The sponge urban rainwater purification collection system 10 of the present invention can be kept away
Exempt from the generation of the above situation.With continuing for rainfall, some of the contaminants that ground is easy to be pulled away are blocked in initial stage drop
Outside rain processing module 20, some of the contaminants flow into the first rainfall processing and collection module 30 with initial rainfall processing module 20,
The floating material feature contained in rainwater is that area is big, light weight, and the first rainfall processing and collection module 30 will first contain in rainwater
Floater filtering go out.Simultaneously after sedimentation, the weight sundries such as silt, stone in rainwater is eliminated.Filtered rainwater
It without containing large particulate matter, while also more cleaning, fire demand water is not high for the quality requirement of water, while without sedimentation in water
Object does not influence fire storage equipment, therefore the rainwater by the processing of the first precipitation and collection module processing can be used as
Fire demand water or road surface spraying water.But part little particle, suspended material are also present in rainwater, if sprayed for gardens
Filling, trickle irrigation etc. easily cause nozzle obstruction, irrigation equipment are caused to damage.Second rainfall processing and collection module 40 further will
The suspended matter contained in rainwater removes, and so that rainwater is further processed, so as to be used for treegarden irrigation and landscape water.Current day
What normal cleaning water used is all tap water, also higher for cost of water treatment since the quality of tap water is higher.In office building
Equal places, it is larger for the demand of cleaning water, therefore the use cost for causing water increases.It handles and receives by the second precipitation
The rainwater of collection resume module contains a small amount of pigment and smell, less meets the requirement of cleaning water, the processing of third precipitation and collection
Module can by rainwater color and smell remove, to enable rainwater for cleaning use.It is thin due to also containing in rainwater
The ingredients such as bacterium, virus, unsuitable animal is drunk or people cleans body.But the cost for handling these ingredients is higher, with the present invention
Technical problem to be solved mutually conflicts, therefore does not consider further that.
