Design of Integrated Treatment System for Sludge from Rain Sewage Pipeline

Abstract

The design of integrated treatment system for sludge from rain sewage pipeline was made by concentrating the garbage sorting, sand separation, sludge stabilization harmless, sludge dehydration and the residual water purification in one. This design was to improve the efficiency of sludge treatment. The composition and dosage of conditioning agents for the sludge were determined according to the characteristics of sludge. After conditioning, the water content of primary dehydration was reduced from 98.9% to 62.46%. The mechanical pressure filtration dehydration
