摘要
分析了含汞废水的成分,探讨了自然沉降法处理含汞废水存在的问题,提出了采用膜过滤法替代自然沉降法处理含汞废水的方案。结果表明:经膜过滤法处理的含汞废水中含汞质量浓度小于0.005 mg/L,同时减少了含汞污泥量,高吸附性材料还可回收利用。
The compositions of waste water containing mercury were analyzed. The problems existing in natural sedimentation process for treatment of waster water containing mercury was discussed. A plan of substituting membrane filtration process for natural sedimentation process was proposed. The results showed that membrane filtration process could lower the content of mercury in waste water to less than 0. 005 mg/L, reduce the amount of sludge, and the high adsorptive materials could be regenerated and reused.
