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 the present embodiment below in detail is as follows:
One, the collection of rainwater and storage.
By rain pipe 1, near rainwater is introduced to shunting well 2, in shunting well 2, be provided with 3 outlets, respectively later stage rain pipe 3, early-stage rainwater pipe 4 and upflow tube 5, its mouth of pipe mounting height is respectively rain pipe 1, upflow tube 5, later stage rain pipe 3, early-stage rainwater pipe 4 from high past low arrangement, the first control valve 6 is installed on later stage rain pipe 3, the second control valve 7 is installed on rain pipe 4 in the early stage.At ordinary times, two control valves are closed.At the rainfall initial stage, open the second control valve 7, the menophania of the higher early-stage rainwater of Pollutant levels, rain pipe 4 flows into sand setting grease removal tanks 33, and is used in after treatment carwash.In the rainfall later stage, close the second control valve, open the first control valve 6, later stage rainwater rain pipe postmenstruation 3 that Pollutant levels are lower flows directly into stormwater tank 8 and stores.After stormwater tank is full, close the first control valve, the rainwater in shunting pond will enter municipal drainage device through upflow tube 5.In shunting well 2, be provided with grid and filter screen, can tackle the larger 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 processed
While storing rainwater in the water-holding quantity of clean water basin 25 can not meet the needs, stormwater tank 8 of carwash, just by the rainwater in stormwater tank, supplement.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 the first strainer 14 by hydraulic pipe 12 and filters.When carrying out rainwater moisturizing and filter, the 5th control valve 20 and the 6th control valve 23 are opened, rainwater after the first strainer 14 successively through the first filter outlet pipe 15, surmount pipe the 22, second filter outlet pipe and enter clean water basin 25.
Clean water basin 25 are for storing new supplementary rainwater and the clear water after circular treatment.The water inlet place in pond is provided with clear water storage after sterilization that group ultraviolet disinfector 26, the second filter outlet pipes 24 are carried.The rising pipe 27 that clean water basin arrange, for the water receiving pipe of car washing installation.Clean water basin 25 can be built in underground, also can be built on ground, and be provided with tap water moisturizing unit, so that rainwater use tap water moisturizing, the water supply of assurance car washing installation when not enough.
Three, wastewater from car washer circular treatment
Wastewater from car washer is collected and is flowed into waste pipe 32 through ground water leg, establishes filtering net, for removing larger assorted slag between water leg and waste pipe.Waste water flows into sand setting grease removal tanks 33 through waste pipe 32, inside stays for some time, and at the bottom of the sand that density is greater than water sinks to pond, density is less than the greasy dirt of water floating to the water surface.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 less silt particle.Mud and sand silting is at the bottom of pond.When waste water reaches after the time of setting in the interior stop of wastewater disposal basin 34, 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 passes through the first strainer 14, the first filter outlet pipe 15, the second strainer 21, the second filter outlet pipe 24 successively through hydraulic pipe 12, finally enters clean water basin 25 and carries out disinfection and store.The first strainer belongs to sand filter, is mainly used in holding back suspended contaminant, and the 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 hand inspection mouth, and for regularly drawing clearly oil slick and heavy mud, settling tank is provided with medicine machine, for dosing coagulant etc.
Four, Filter Back Washing
The 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 declines, and therefore need to carry out back flushing to strainer.When the difference of reading of current pressure meter 16 and rear 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 the first strainer 14 by the clear water pressurization of clean water basin 25 by recoil tube 30, the first filter outlet pipe 15.The waste water that back flushing is discharged is discharged from hydraulic pipe 12 rear ends, drains into municipal wastewater pipeline outside water shoot 17.After back flushing finishes, close the 4th control valve and recoil pump, and open the 5th control valve 20.
Five, device is controlled
Apparatus of the present invention arrange automatic control unit, by a PLC controller, receive each liquidometer and manometric data, and according to the keying of each control valve and water pump in the condition transmission instruction control unit of setting.
Concrete case study on implementation 2:
With reference to Fig. 2, the feature of the present embodiment 2 is: near the built rain rainwater storage facilities such as structures of regulating and storing carwash shop when the present embodiment 2 can not established rainwater shunting well and stormwater tank, and directly extract make up water from existing rainwater storage structures 41.All the other functional structures are with specific embodiment 1.
Specific embodiment 3:
The feature of the present embodiment 3 is: tap water input port (not shown in FIG.) is set in clean water basin 25, and automatic control device is controlled the ON/OFF of tap water input port according to clean water basin 25 water levels.All the other functional structures are with specific embodiment 1 or specific embodiment 2.
