Application of a Novel Cationic Polyacrylamide as Flocculant in Treatment of Papermaking Wastewater
As we known, now wastewater from papermaking has been the main source of water pollution in China. Polyacrylamide is one of water treatment chemicals which have been used widely. In laboratory, we prepared a novel cationic polyacrylamide (CPAM) with acrylamide (AM) and acryloyloxyethyltrimethyl ammonium chloride through dispersion polymerization in aqueous solution of ammonium sulfate. Cationic polyacrylamide (CPAM) made by ourselves is with high molecular weight and high charge density, and its stability and dissolvability are both excellent. In this paper, the CPAM made by ourselves is used as flocculant cooperating with polyaluminium chloride (PAC) to treat the papermaking wastewater, the results indicate that the CPAM is an excellent flocculant for papermaking wastewater.
