In the present embodiment, the early-stage rainwater desertion device 2 is using wall-mounted.The cistern 3, pressure filter 4 use
Ground type.
Electric flocculation device, quartz sand filter, automatic back-flushing device are provided with the purifying water process equipment 5.Water
Electric flocculation device in purification apparatus 5 carries out coagulating sedimentation, and quartz sand filter carries out impurity screening, automatic backwash
Device is backwashed, and the water-purifying process combination of traditional coagulation, precipitation, filtering is completed in an equipment.
The feed pump 8 is feedwater centrifugal pump, and water tank 7 is pressurizeed to user pipe using feedwater centrifugal pump.
Operation principle of the present utility model is：After rainwater is by grid 1 and early-stage rainwater desertion device 2, into water storage
Pond 3.Water in cistern 3 enters pressure filter 4, the water outlet water receiving purification apparatus 5 of pressure filter 4, by water through over pressurizeed
Water quality after purification apparatus 6 and ultrafiltration membrane treatment equipment 6 are handled reaches user with water water quality requirement, ultrafiltration membrane treatment equipment
Clean water access water tank 7 after 6 processing is stored, and ultraviolet sterilizer is set in water tank 7, and fresh water passes through in water tank 7
Feed pump 8 is pressurizeed, and fresh water is fed into user's domestic water line.
Specific handling process of the present utility model is as follows：
Grid：Rainwater enters grid after confluxing, and the larger object of volume in raw water is retained with grid, as leaf,
The debris such as polybag.Manual grid is set, with object-catching, artificial slagging-off.
Early-stage rainwater desertion device：After grid, rainwater enters early-stage rainwater desertion device, early-stage rainwater abandon be for
A part of rainwater during it rained just now is carried out abandoned stream, it is not collected.Dust in air can be deposited to roofing, caused
Suspension is dissolved in rainwater when raining, and is caused early-stage rainwater more muddy, can be increased processing cost, therefore its abandoned stream is contributed to
Improve the water quality for collecting rainwater.The first rain amount of abandoning of roofing is 1 ~ 2mm, can meet to require.Early-stage rainwater desertion device is provided with
Ball-cock assembly, when water level rises, ball-cock assembly progressively closes off, and when the first rain amount of abandoning of roofing is 2mm, ball-cock assembly completely closes.Abandon
Rainwater after stream imports cistern, and the rainwater of abandoned stream discharges into sewage conduct.
Cistern：After by grid retention and just rain is abandoned, rainwater is discharged into cistern, and cistern has storage, adjusted
Section, the pond of precipitation, for storing collected rainwater after first rain is abandoned.Cistern is provided with overflow pipe, works as collection
Amount of rainfall when being more than the dischargeable capacity of cistern, rainwater discharges cistern by overflow pipe, is provided with boost in pressure in cistern
Pump, pressure is provided for whole rainwater advanced purification treatment system.
Pressure filter：Filter plant selects pressure filter, and the mainly rainwater after abandoned stream still contains certain density solid
Suspension, loss of flood peak increase is very fast during filtering, and pressure filtration can preferably solve this problem, and water head-drop can also expire
Requirement after foot processing, it is not necessary to lifted again.The rugosity of pressure filter filtrate, thickness are all bigger than universal rapid filter, particle diameter one
As use 0.6~1.0 millimeter, filtrate is thick general with 1.1~1.2 meters.Filtering velocity is 8~10 ms/hour, even more greatly, using thick
When filtrate and big filtrate thickness, normal consideration aids in rinsing with compressed air, to save washing water quantity, improves developing result.Pressure
Pressure gauge is equipped with the inlet tube and outlet tube in filter tank, the difference of two meter pressures is exactly loss of flood peak when filtering, and general optional 5~6
Rice, sometimes up to 10 meters.Clearance type filter in the more system using slight drag of water distribution system.Pressure filter takes up an area less, again
There is approved product, the construction period can be shortened, and running management is convenient, using wider in samll cities and towns or small engineering.
Purifying water process equipment：Purifying water process equipment combines the water-purifying process of traditional coagulation, precipitation, filtering one
Completed in individual equipment, take up an area less, be easy for installation.Its principle is：1. electric flocculation carries out coagulating sedimentation.2. quartz sand filtration impurity,
Automatic backwash.
Ultrafiltration membrane treatment equipment：To ensure drinking water quality, poisonous and harmful substance in water is controlled, using ultrafiltration membrane technique.
Ultrafiltration carries out separation of solid and liquid using the high-precision cutoff performance of ultrafiltration or makes different relative molecular masses using pressure difference as driving force
The membrane separation technique of material classification, can be concentrated and be separated simultaneously macromolecular or colloidal substance, its equipment is low without phase transformation, energy consumption
And film selectivity is high.
Water tank：Life water up to standard is handled to store into stainless steel water tank.Ultraviolet disinfection is provided with stainless steel water tank to fill
Put.Wherein, ultraviolet sterilization is mainly the ultraviolet using 254 nano wave lengths.The ultraviolet of this wavelength, even micro-
Under the ultraviolet projection dosage of amount, life core --- the DNA of a cell can also be destroyed, therefore prevents cytothesis, funeral
Losing power of regeneration makes bacterium become harmless, so as to reach the effect of sterilizing, ensure that domestic water water quality.
Feed pump：In stainless steel water tank peripheral hardware feed pump, pressurizeed by feed pump, fresh water is delivered to islands and reefs service pipe
In.
Impurity and the microorganism in eaves rainwater can be removed by above rainwater treatment flow, while rain should be detected
The indexs such as pH value, colourity, turbidity, metal ion in water, to meet《Standards for drinking water quality》.According to existing islands and reefs allusion quotation
11 index analysis of type rainwater-collecting and the rainwater sample of processing system, meet《Standards for drinking water quality》（GB
