PURPOSE:To improve a polymer coagulant which is used for treating muddy water produced from muddy water type shield works, underground continuous wall works, stabilizer drilling works, etc., to demonstrate sufficient effects with a small amount of the coagulant by mixing it with highly concentrated muddy water easily in a short time and distributing it uniformly. CONSTITUTION:A coagulant for civil engineering prepared by mixing anionic polyacrylamide with a molecular weight of one million or more and polycarboxylic acid salt with a molecular weight of 100 thousand or less in a ratio of 1:(0.05-1) by weight. |
