Effect of Polymer Coagulant on the Dewatering Characteristic of Sludge[J]. Journal of Civil and Environmental Engineering, 2003, 25(6): 89-93. DOI: 10.11835/j.issn.1674-4764.2003.06.019.
Based on analysis of the characteristic of the sludge
in this paper
three kinds of sludge were selected to make coagulant experiment with three different coagulants. The specific resistance to filtration is tested. Finally
the optimum coagulant with its optimum dosage is obtained and the dewatering effect is improved.
