摘　　要：研究了采用新型无机高分子絮凝剂——聚硅硫酸铁(PFSS)处理钢铁厂转炉二文除尘废水。结果表明:PFSS絮凝剂用量、废水pH值等参数对絮凝沉降效果有很大影响,而温度影响较小。当废水pH=6.0、PFSS投加量为0.25mL/L时,PFSS对废水浊度、悬浮物去除率分别达99.11%和97.86%,废水处理效果较好。A new type of inorganic polymer flocculant polyferric silicate sulfate（PFSS）has been used for treating of dust removing waste water from steel plant.The results show that the amount of added PFSS and pH of the waste water affect flocculant effect,but water temperature has weaker influences on removal rate of turbidity and suspended solids in waste water.At the conditions of PFSS adding of 0.25 mL/L,pH of 6.0,the removing rate of turbidity and suspended substance can reach 99.11% and 97.86%,respectively.
