摘要
通过过氧化氢氧化、水解、聚合制备聚合硫酸铁,并对合成聚合硫酸铁的条件进行研究。将得到的产品用于模拟高岭土废水的处理,浊度去除率可达97%,用于污水处理厂总入水口废水的处理,COD去除率达到64%,并对其应用的最佳条件进行了研究。
Polyferric sulphate （PFS） was prepared via H2O2 oxidation, hydrolysis and polymerization. And PFS preparation conditions were studied. Then PFS was used to treat simulative Kaolin wastewater. After the treatment, the color removal rate can reach 97%. When PFS was used to treat inlet wastewater of the sewage treatment plant, the COD removal rate can achieve 64%. At last, optimum application conditions were studied.
