为优化矿井水反渗透处理的系统设计，采用分析研究与工程实践相结合的方法，以某煤矿水处理工程为例，对设计水温、设计回收率、膜元件数量及排列形式等要素进行了探讨。结果表明：根据水质特点和工艺要求，通过计算比较可以确定设计水温为25℃，并且满足校核条件；通过对主要结垢组份的分析，可以确定设计回收率为60%，限值为67%；通过对比不同的膜元件数量与排列形式对系统的影响，可以确定采用144只膜元件和一级二段的配置形式；工程运行实践表明，据此设计、运行的反渗透系统可以降低膜结垢的风险，有利于系统长期稳定运行，对于煤矿矿井水反渗透处理系统的设计运行有一定指导意义。

In order to optimize the system design of reverse osmoses (RO) for a mine drainage water treatment engineering as a case, this paper discusses the key design factors involving design water temperature, design recovery rate, numbers of RO membrane elements and arrangement types, by adopting the method combined analysis investigation with engineering practices. According to the water quality characteristics and the process requirements, the design water temperature of 25℃ is presented by calculation and comparison, and the checked condition is given as well. The design recovery rate of 60% and the limited recovery rate of 67% are determined by analyzing the main scaling components. Adopting the membrane element numbers of 144 and the configuration of one pass and two stages are considered by analyzing the effects on the water system caused by different membrane components and arrangement types. The engineering operation practice shows that the designed and operated RO system adopted the method reduces the scaling risks of RO membranes, has the benefits of stable operation for a long time, and has some guiding significance for designing and running the RO systems to treat mine drainage water.
