Most of the newly built sludge discharge facilities in old WTPs face land scarcity issues.In view of the water quality characteristics of large turbidity,high degree of coagulation and good separation,as well as the treatment goals of sludge wastewater content less than 80％and supernatant suspension not higher than 50 mg/L in a WTP in southern China,a WTP adopts an integrated equipment treatment process"integrated multi-effect clarification system+belt concentration dewatering".The system optimizes the coagulation reaction zone and sedimentation zone based on the characteristics of sludge wasterwater to improve operational efficiency,the project operates stably and reliably,the sludge moisture content is less than 65％,and the supernatant suspension is less than 15 mg/L,which has the advantages of low investment,small land occupation and good treatment effect in the same type of project.
