The invention belongs to the technical field of waste
water treatment equipment, and discloses a car-washing waste
water treatment device. The car-washing waste
water treatment device comprises a waste water collecting tank, wherein a plurality of collecting holes are formed in the top of the waste water collecting tank; the waste water collecting tank is communicated with a
sediment tank through a water pump; a water outlet of the water pump is close to the bottom of the
sediment tank; a dosing device for adding flocculating agent is arranged on the
sediment tank; the sediment tank is communicated with a filter tank through a
pipe; a first filter plate and a second filter plate are arranged in the filter tank; the
pipe penetrates through the first filter plate and the second filter plate; the outlet end of the
pipe is located below the second filter plate; the filter tank which is located above the first filter plate is equipped with a water discharging pipe; the water discharging pipe is communicated with an
active carbon filter; the
active carbon filter is further communicated with a disinfecting tank; an
ozone generator is arranged on the disinfecting tank; the disinfecting tank is communicated with a
clean water reservoir. The car-washing waste water treatment device is simple in structure and low in treatment cost, has a good treating effect because the car-washing waste water treatment device can perform multi-stage purification treatment including flocculent
precipitation, filtering by the filter plates, filtering by the
active carbon filter,
ozone disinfection and so on, and can be widely popularized to be used.
