| 中文摘要: |
| 采用微絮凝直接过滤工艺对阜新矿区的微污染矿井水进行处理,对相关参数进行了优化并研究了过滤特征。试验结果得出:絮凝剂聚合氯化铝最佳投药量和絮凝时间分别为2~4mg/L和3~4min,最优滤速为10~14m/h,此时过滤周期可达到30~40h,出水浊度和悬浮物浓度可分别达到1NTU和5mg/L以下,符合回用水标准。 |
| 英文摘要: |
| The paper used the micro-flocculation direct filtration process to treat the micro-polluted mine water in Fuxin mine area, optimized the related parameters and researched the characteristics of filtration.The results show that the optimum dosage of PAC and flocculation time are 2~5mg/L and 3~4min, the optimum filtration rate is 10~14m/h, at this time the filtration cycle can reach 30~40h, the turbidity and suspended solids concentration of effluent water can reach respectively below 1NTUand 5mg/L, and it can accord with the national sanitation of reusing water. |
