摘要： 针对永城开控矿井水回用项目的工艺过程及现场条件，通过理论分析、计算及实验研究，提出控制硬度、调节pH、选定最佳回收率、优选阻垢剂的综合因素分析及控制法. 结果表明，该矿井水反渗透安全经济运行的最佳进水条件为钙浓度<160 mg/L、加酸调节pH至7.4、阻垢剂加药量2.8?10?6 (?). 运行3年来反渗透膜系统结垢问题得到有效控制，压差及脱盐率变化较小.

Abstract: According to the process and site conditions of the Yongcheng Kaikong reuse mine water project, it was suggested to control the hardness, regulate pH, select the reasonable rate of recovery and optimize the choice of antiscalant after theoretical analysis, calculation and experimental study. The optimal conditions for a safe and economical reverse osmosis system were calcium concentration lower than 160 mg/L, pH equal to 7.4, antiscalant dosage 2.8?10?6(?). The results of three-year running showed that the scaling problem has been effective controled, and the pressure difference and the desalination rate have undergone little change.
