Further describe equipment of the present invention below by working process, the present invention adopts following process that waste water is handled:
1) wastewater from car washer is crossed the ditch by graticule mesh under the car wash site and is collected into pump well, and it is just heavy to carry out;
2) start lift pump 1, wastewater from car washer is after grid and oil removal felt are further removed solid sundries and oil slick, be drawn into retort 33 bottoms through water intaking valve 2, when the little aeration head 3 of water inlet submerged diaphragm type, aerator 4 starts, intake valve 5 is opened, begin to carry out aeration, meanwhile, medicine-sucking pump 6 starts, dosing valve a7 opens, the combined oxidation toughener that begins to add among the dosing tank a8 carries out the aeration oxidizing reaction, this moment, agitator motor 10 also started synchronously, stir, after the combined oxidation toughener finishes by pre-selected amount of medication, medicine-sucking pump 6 and dosing valve a7 close, cleaning shoe 12 is scraped the foam and the suspending sundries of liquid level to semi-circular receiving tank 13, be disposed to the underground ditch of crossing through upflow tube 14 and flow back to pump well, behind the aeration oxide treatment 30min, close aerator 4 and intake valve 5, meanwhile, medicine-sucking pump 6 starts, and dosing valve b15 opens, and begins to add that polynary compound inorganic high molecular flocculant polymeric aluminium ferrum silicate carries out aggregation among the dosing tank b16, add by pre-selected amount of medication and to finish, close medicine-sucking pump 6 and dosing valve b15, at 35r/min, PH8.5 left and right sides aggregation 5min is behind the aggregation, medicine-sucking pump 6 restarts, open dosing valve c17, the organic coagulant aids polyacrylamide that begins to add among the dosing tank c18 carries out coagulating, adds by pre-selected amount of medication to finish, close medicine-sucking pump 6 and dosing valve c 17, at 35r/min, PH8.5 left and right sides aggregation 2min; Coagulating is closed agitator motor 10 after finishing, and multi-functional agitating vane 11 stops to stir; Leave standstill 10min and precipitate, the diaphragm mud cover 19 that aeration head 3 tops are installed in universal mixer 11 lower ends that declines is keeping off precipitating sludge, avoids little aeration head 3 to be covered by mud and stops up; After sedimentation finishes, start lift pump 1 once more, open surplus water valve 20, emit and remain sewage in the pipeline, close surplus water valve 20 behind the 5s, open strainer water intaking valve 22 simultaneously, water outlet is filtered to the oxidation enhanced coagulation, filters water outlet and drains into sterilization aeration settling pond 24 through self-cleaning filter 21 rising pipes 23; Spissated dense slag liquid is not regularly shut down from its sewage draining exit 30 and directly is disposed to the underground ditch of crossing and is back to the pump well in the self-cleaning filter 21; When treating water is disposed to the following water level of water level detector 9 in the retort 33, lift pump 1 and self-cleaning filter 21 water intaking valves 22 are closed, open retort 33 mud valves 28 and put mud, after mud has been put, open tap water back-washing valve 29 flushings 5s minute, sludge discharged and back flushing are back in the pump well through the underground ditch of crossing.Close after muddy water has been arranged after mud valve 28 and back-washing valve 29, the first circulating treatment procedures finish, repeat above-mentioned 2) process carries out second circular treatment, and so forth, waste water uninterruptedly handled.
Be collected into treating water in the aeration settling pond 24 through throwing sterilizing agent, open the aeration valve 25 of sterilization aeration tank 24, carry out gap aeration, clarification by porous aeration tube 26, primary water overflows the mouth of a river 31 overflows from sterilization aeration settling pond top and goes out, and is back to carwash; Precipitation then drains into the underground ditch of crossing from the mud discharging mouth 27 of funnel-form bottom and is back to the pump well; Pump well is regularly drawn clearly, and the mud outward transport is handled.
