摘要
针对电厂的脱硫废水,开展纳滤脱盐中试试验,当纳滤回收率在68.94%~80.83%时,高压泵出口压力为2.26~2.39 Mpa,产水电导为8.14~14.33 mS/cm。纳滤膜污堵后,经过酸碱清洗,纳滤膜通量可以完全恢复。
In view of the desulfurization wastewater in power plants,pilot test of nanofiltration desalination is conducted.As the nanofiltration recovery was 68.94%~80.83%,the outlet pressure of the high-pressure pump was 2.26~2.39 mpa,and the water conductivity was 8.14~14.33 mS/cm.After acid and base cleaning,the nanofiltration membrane flux can be completely recovered.
