摘要
论文介绍了用微絮凝-纳滤组合工艺处理含悬浮物矿井水的工艺流程。通过试验,确定了微絮凝过滤的最佳投药量。在过滤周期为30min时,采用反曝气方式运行的微絮凝-纳滤膜装置的组合工艺处理矿井水,对浊度和细菌的去除率分别达到99.8%和88%,系统出水的各项指标也达到了用水要求。
The paper introduced the combined technology of micro coagulation and nano-filtration applied to the treatment processing of mine water with suspended material. After the tests, the paper set up the optimized consumption of the coagulant for the filtration. The filtration period is 30 minutes. The mine water treatment was operated with the micro coagulation and nano-filtration combined technology with the reversed air blasting method. The turbidity and bacteria removing rate are reached to 99.8% and 88% individually. Each index of the water from the outlet of the system also can reach the water requirements.
