A new type of coagulant polymeric ferric silicate-chloride containing boron is prepared by using water glass, ferric chloride and borax as raw materials. Optimal preparation conditions are as follows:n(Fe):n(Si) = 1.0 and n(B):n(Si) = 0.16. And the effectiveness of COD removal and flocculation on the papermaking wastewater and coke plant wastewater is also tested. Compared with the other flocculants,the new flocculant better for COD removal and flocculation.
