| 摘 要： | 针对韩桥矿高铁矿井水质，考察了混凝＋沉淀＋过滤回用处理工艺除铁的最佳运行条件。结果表明，以聚合氯化铝（PAC）作为混凝剂，最佳投药量为80mg／L时，铁的去除率可达到91％；选择天然锰砂作为滤料，滤速在8～10m／h，进水pH值高于6．05，滤层高度大于75cm时，锰砂除铁效果较好，出水铁含量在0．1mg／L以下，可以满足《城市污水再生利用工业回用水水质》（GB／T19923--2005）中的限值要求。

| Abstract: | Based on the characteristics of Hanqiao mine water with high concentration of iron, the optimum operational condition of iron removal for reclamation and reuse process adopted by coagulation- sedimentation-filtration was investigated. The results showed that the removal rate of iron could reach 91% when PAC was the coagulant and the optimum dosage was 80 mg,/L. The effect of iron removal by manganese sand was better, the content of effluent iron was below 0. 1 mg/L and it could satisfy the requirement of Reuse of Urban Recycling Water - Water Quality Standard for Industrial Uses （ GB/T 19923 - 2005 ） when natural manganese sand was the filter media, filtration rate was 8 to 10 m/h, influent pH was higher than 6.05 and fiher height was higher than 75 cm. |
