In actual applications, the water input terminus of carwash unit connects the rising pipe 27 of clean water basin 25.
The principle of work of describing present embodiment below in detail is as follows:
One, the collection of rainwater and storage.
By rainwater pipe 1 near rainwater is introduced shunting well 2, be provided with 3 outlets in the shunting well 2, be respectively later stage rainwater pipe 3, early-stage rainwater pipe 4 and upflow tube 5, its mouth of pipe mounting height is respectively rainwater pipe 1, upflow tube 5, later stage rainwater pipe 3, early-stage rainwater pipe 4 from high past low arrangement, at later stage rainwater pipe 3 first control valve 6 is installed, second control valve 7 is installed on the rainwater pipe 4 in the early stage.At ordinary times, two control valves are closed.At the rainfall initial stage, open second control valve 7, rainwater pipe 4 flows into sand setting grease removal tanks 33 menophania of the higher early-stage rainwater of Pollutant levels, and is used in carwash after treatment.In the rainfall later stage, close second control valve, open first control valve 6, the later stage rainwater rainwater postmenstruation pipe 3 that Pollutant levels are lower flows directly into stormwater tank 8 and stores.After stormwater tank is full, close first control valve, the rainwater in shunting pond will enter the municipal drainage device through upflow tube 5.In shunting well 2, be provided with grid and filter screen, can tackle the bigger assorted slag that rainwater is carried secretly.Stormwater tank 8 is built in underground, builds jointly with sand setting grease removal tank 33 and settling tank 34.
Two, rainwater is handled
When in the water amount of clean water basin 25 can not satisfy the needs, stormwater tank 8 of carwash, storing rainwater, just replenish by the rainwater in the stormwater tank.Rainwater will pass through filtration treatment before adding to clean water basin 25.Close the 7th control valve 37, open the 3rd control valve 9 and force (forcing) pump 11, rainwater just enters first strainer 14 by hydraulic pipe 12 and filters.When carrying out the rainwater moisturizing and filter, the 5th control valve 20 and the 6th control valve 23 are opened, rainwater behind first strainer 14 successively through first filter outlet pipe 15, surmount pipe 22, second filter outlet pipe and enter clean water basin 25.
Three, wastewater from car washer circular treatment
Wastewater from car washer is collected through the ground water leg and is flowed into waste pipe 32, establishes filtering net between water leg and the waste pipe, is used for removing bigger assorted slag.Waste water flows into sand setting grease removal tanks 33 through waste pipe 32, inside stays for some time, and density sinks at the bottom of the pond greater than the sand of water, and density is floating to the water surface less than the greasy dirt of water.Waste water through sand setting and oil removing flows into settling tank 34 through pipe connecting 35 again, and waste water stops the longer time in settling tank, is removed littler silt particle.Silt particle is deposited at the bottom of the pond.When waste water in wastewater disposal basin 34, stop reach the time of setting after, just open force (forcing) pump 11 (closing the 3rd control valve 9, the 4th control valve 18 and the 6th control valve 23), the waste water that settling tank is 34 li just through hydraulic pipe 12 successively by first strainer 14, first filter outlet pipe 15, second strainer 21, second filter outlet pipe 24, enter clean water basin 25 at last and carry out disinfection and store.First strainer belongs to sand filter, is mainly used in holding back suspended contaminant, and second strainer belongs to absorption or biochemical reactor, mainly removes dissolubility pollutant.Sand setting grease removal tank 33 and settling tank 34 are provided with the hand inspection mouth, are used for regularly drawing oil slick and heavy mud clearly, and settling tank is provided with medicine machine, are used for dosing coagulant etc.
Four, strainer back flushing
First strainer is after operation for some time, and the pollutent of holding back can stop up the space of filtrate, causes head loss to increase, and processing power descends, and therefore need carry out back flushing to strainer.When the difference of reading of current pressure meter 16 and back pressure warning unit 19 reaches the numerical value of setting, open backwashing procedures.During back flushing, open the 4th control valve, close the 5th control valve 20, open recoil pump 29 simultaneously, recoil pump enters first strainer 14 with the clear water pressurization of clean water basin 25 by recoil tube 30, first filter outlet pipe 15.The waste water that back flushing is discharged is discharged from hydraulic pipe 12 rear ends, drains into the municipal wastewater pipeline outside water shoot 17.Back flushing is closed the 4th control valve and recoil pump, and is opened the 5th control valve 20 after finishing.
Five, device control
Apparatus of the present invention arrange automatic control unit, receive each liquidometer and manometric data by a PLC controller, and send the keying of each control valve and water pump in the instruction control unit according to the condition of setting.
Concrete case study on implementation 2:
With reference to Fig. 2, the characteristics of present embodiment 2 are: had the rainwater rainwater storage facilities such as structures of regulating and storing near the carwash shop, when present embodiment 2 can not established rainwater shunting well and stormwater tank, and directly extracted make up water from existing rainwater is regulated and stored structures 41.All the other functional structures are with specific embodiment 1.
Specific embodiment 3:
The characteristics of present embodiment 3 are: tap water input port (not drawing among the figure) is set in clean water basin 25, and automatic control device is according to the ON/OFF of clean water basin 25 water levels control tap water input port.All the other functional structures are with specific embodiment 1 or specific embodiment 2.
