The polymeric ferric silicate sulfate flocculants which have dif ferent Si to Fe ratio have been produced by four methods.Through the paper-making wastewater treatment,the different preparations and the performances of the product which are made in different Si to Fe ratio have been compared.The result shows that when the Si to Fe ratio is 1∶20,the flocculation effect of the product made by putting the sodium silicate reagent direct ly into poly-iron is the best.The product made by put ting the poly-silicic acid which is polymerized with soluble glass into poly-iron has better flocculation ef fect and is cheaper in price.So,the best technological conditions of polymeric ferric silicate sulfate preparation have been got
