Study on the Characteristics of Biochemical Sludge and Its Treatment in Sludge Drying Equipment
As there is no steam heat source during the major overhaul of a coal chemical company,biochemical sludge and tank bottom sludge generated from the major overhaul cannot be dried,this paper screened the flocculant used in the sludge advanced treatment and pretreatment stage,and conducted a small test on the selected process.Finally,flocculant No.883 was determined,and the dosage was 0.16 kg/t mud.The moisture content can be reduced to less than 82%,and after 2 h sludge low-temperature drying treatment,the sludge moisture content can be reduced to less than 30%,effectively solving the problem of sludge treatment and sludge system imbalance during major overhaul.
