Summary: | The invention relates to the technical field of construction site sludge and wastewater treatment, and discloses a green construction method for whole-process collection and filter-pressing treatment of sludge and wastewater of a car washing pool, which comprises the following steps: 1) washing a vehicle in the car washing pool; 2) pretreating in a third-stage sedimentation tank; (3) pumping wastewater by a diaphragm pump; 4) squeezing and filtering the wastewater; and 5) recycling clear water. According to the construction method, a filter press is arranged nearby the three-stage sedimentation tank on site, clear water obtained after sludge wastewater is subjected to filter pressing treatment is recycled, sewage and wastewater generated by car washing are solved on site, discharge of a large amount of sewage and outward transportation of sludge are avoided, mud cakes can be used for manufacturing environment-friendly bricks after the sludge wastewater is subjected to solid-liquid separation, clear water can |
