摘　　要：应用处理量8m3/h的压紧式改性纤维球压力过滤器,对某钢铁厂热轧浊循环水进行处理.结果表明,采用纤维球过滤能有效的去除热轧浊循环水中的油类和悬浮物(SS),过滤后的出水中油含量能降低到1.8～4.5 mg/L,去除率达到84.5%,悬浮物(SS)最高9.5 mg/L,平均5.04mg/L,去除率达到88.77%,满足该厂要求热轧循环用水油含量≤5 mg/L,悬浮物≤10 mg/L的要求.Hot-rolling circulation water in an iron and steel plant is treatd by pressure filter tank filling with modified fiber ball media.The pressure filter tank has a capacity of 8 m3/h to treat the water.The results show that this method can remove oil and SS in hot-rolling circulation water effectively.The average treating efficiency of oil and SS is 84.5% and 88.77%.Oil concentration of water can be decreased to 1.8～ 4.5 mg/L, and SS to 1.0～9.5 mg/L,which meet the needs of hot-rolling circulation water, whose oil concentration must be less than 5 mg/L, and SS concentration less than 10 mg/L.
