| Abstract: | Waterworks sludge treatment should be conducted to reduce wastewater discharge and save water use cost.The scale of the waterworks is 200 000 cubic meters per day and the designing amount of total dry solid sludge is 31.14 ton per day.The backwash water from filter is discharged into the wastewater tank.After adjusted,it was drained into the clarifier and reclaimed.The clarifier sludge is collected by the sludge tank.Together with the bottom sludge of wastewater tank,it is thickened and dewatered by mechani... |
