介绍了反渗透技术在矿热炉补充水除盐工艺中的应用,并进行了原水悬浮物浓度、硬度和RO膜两侧静压差对系统运行状况、产水量和除盐率影响的测试.结果表明,原水悬浮物对系统产水量有严重影响;原水硬度对RO产水量影响相对较小;RO膜两侧静差降低,有利于提高除盐率.增加组合深度预处理工序,降低原水的悬浮物浓度,强化预处理阶段杀菌灭藻,对除盐系统设备正常运行起关键作用.

This paper introduced the application of reverse osmosis technology to the desalination process in supplement water for submerged arc furnace. It tested the effects of original water suspended matter concentration,hardness and static pressure difference both sides of RO membrane on system operation, water yield and desalination rate. The result shows that original water suspended matter has great effects on system water production and original water hardness has less ef-fect on RO water production. It is beneficial to enhance desalination to decrease the static pressure difference both sides of RO membrane. It plays a key role in normal operation of system to increase combined deep pretreatment, decrease the original water concentration and strengthen germicide and algicide in pretreatment stage.
