ABSTRACT

According to statistics, the excess sludge production in China is about 7.602∼12.670 × 104 m3/d[1]. The treatment and disposal of sludge has become an urgent problem. The sludge dewatering is the key process in the sludge disposal process. The study found that the change of its physicochemical properties in the sludge conditioning process has a great influence on the sludge dewaterability.
