The present invention is further explained below in conjunction with drawings and Examples.
Specific embodiment
Fig. 1 is the schematic diagram of rainwater advanced treatment apparatus of the present invention.Including be sequentially connected early-stage rainwater desertion device 2, Cistern 3, pressure filter 4, purifying water process equipment 5, ultrafiltration membrane treatment equipment 6, water tank 7, feed pump 8, early-stage rainwater is abandoned The delivery port of device 2 is communicated with cistern 3, is communicated by head conduit between cistern 3 and pressure filter 4, pressure filter The delivery port in pond 4 is communicated with the water inlet of purifying water process equipment 5, the delivery port and ultrafiltration membrane treatment of purifying water process equipment 5 The water inlet of equipment 6 is communicated, and the delivery port of ultrafiltration membrane treatment equipment 6 is connected with the water inlet of water tank 7, and the water in water tank 7 passes through Feed pump 8 is delivered to user.
In the present embodiment, grid 1 is provided with before the early-stage rainwater desertion device, and grid 1 is arranged at early-stage rainwater and abandons Device 2 enters water front end.
In the present embodiment, the early-stage rainwater desertion device 2 is provided with abandoned stream pipe.
In the present embodiment, ultraviolet sterilizer is provided with the water tank 7.
In the present embodiment, the water tank 7 is stainless steel water tank.
In the present embodiment, compression pump is additionally provided with the cistern 3, the water in cistern 3 is defeated by compression pump and pressure Send pipeline to pressure filter 4.
In the present embodiment, the early-stage rainwater desertion device 2 is using wall-mounted.The cistern 3, pressure filter 4 are used 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 of traditional coagulation, precipitation, filtering is combined into the completion 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 invention is:After rainwater is by grid 1 and early-stage rainwater desertion device 2, into cistern 3. Water in cistern 3 enters pressure filter 4, the water outlet water receiving purification apparatus 5 of pressure filter 4, by Water warfare by pressurization Water quality after processing equipment 6 and the treatment of ultrafiltration membrane treatment equipment 6 reaches user and uses water water quality requirement, at ultrafiltration membrane treatment equipment 6 Clean water after reason accesses water tank 7 and stores, and ultraviolet sterilizer is set in water tank 7, and fresh water is by feedwater in water tank 7 Pump 8 is pressurizeed, and fresh water is fed into user's domestic water line.
Specific handling process of the invention is as follows:
Grid:Rainwater enters grid after confluxing, with the object that volume in grid retention raw water is larger, such as leaf, plastics The debris such as bag.Manual grid is set, with object-catching, artificial slagging-off.
Early-stage rainwater desertion device:By after grid, rainwater enters early-stage rainwater desertion device, early-stage rainwater abandon be for A part of rainwater during it rained just now carries out abandoned stream, it is not collected.Dust in air can be deposited to roofing, caused During suspension dissolves in rainwater when raining, cause early-stage rainwater more muddy, processing cost can be increased, 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 requirement.Early-stage rainwater desertion device is provided with Ball-cock assembly, when water level rises, ball-cock assembly is progressively closed off, and when the first rain amount of abandoning of roofing is 2mm, ball-cock assembly is completely closed.Abandon Rainwater after stream imports cistern, and the rainwater of abandoned stream is discharged into sewage conduct.
Cistern:After grid retention and first rain are abandoned, rainwater is entered in cistern, and cistern has storage, adjusts 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 more than cistern dischargeable capacity when, rainwater by overflow pipe discharge cistern, boost in pressure is provided with cistern Pump, for whole rainwater advanced purification treatment system provides pressure.
Pressure filter:Certain density solid is still contained in filter plant selection pressure filter tank, the mainly rainwater after abandoned stream Suspension, the loss of flood peak increases very fast during filtering, and pressure filtration can preferably solve this problem, and water head-drop can also expire Requirement after foot treatment, it is not necessary to lifted again.Rugosity, the thickness of pressure filter filtrate 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 is aided 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, general optional 5~6 Rice, sometimes up to 10 meters.Clearance type filter in the more use slight drag system of water distribution system.Pressure filter takes up an area less, and 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 one the water-purifying process of traditional coagulation, precipitation, filtering Complete in individual equipment, take up an area less, 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 control water, using ultrafiltration membrane technique. Ultrafiltration carries out separation of solid and liquid or makes different relative molecular masses with pressure difference as driving force using the high accuracy cutoff performance of ultrafiltration The membrane separation technique of material classification, can simultaneously be concentrated and be separated macromolecular or colloidal substance, and its equipment is without phase transformation, and energy consumption is low And film selectivity is high.
Water tank:Treatment life water up to standard is stored into stainless steel water tank.Ultraviolet disinfection dress is provided with stainless steel water tank Put.Wherein, ultraviolet sterilization mainly uses the ultraviolet of 254 nano wave lengths.The ultraviolet of this wavelength, even micro- Under the ultraviolet projection dosage of amount, it is also possible to destroy life core a --- DNA for cell, therefore prevent cytothesis, funeral Losing power of regeneration makes bacterium become harmless, so as to reach the effect of sterilizing, it is ensured 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 the rainwater sample of type rainwater-collecting and processing system, meet《Standards for drinking water quality》(GB 5749-2006)Requirement, specific targets refer to following table.
The Rainwater Quality monitoring result of islands and reefs rainwater-collecting and treatment engineering
