Abstract:
By pilot-scale experiments,the feasibility of electrosorption technology used for treating urban reclaimed water has been studied.The results show that when the equipment flow rate is 0.5 m3/h,polar plate voltage is 1.5 V,and average conductivity of influent is 1 860 μS/cm,the average desalting rate is 74.8% and energy consumption is 1.42 kW·h/t.When the average influent conductivity is 3 862 μS/cm,the desalting rate is 72.4%,energy consumption is 1.86 kW·h/t,and average water productivity is 82.2% during the pilot-scale experimental period.Electrosorption technology has good removing effects on TDS,chloride and total hardness.Furthermore,it is characterized by low energy consumption,high water productivity and simple operation.It can be used for the desalination treatment of urban sewage reclaimed water.

摘要：
通过中试试验,对电吸附技术处理城市再生水的可行性进行了研究。结果表明,当设备进水流量0.5m3/h,极板电压1.5 V时,在平均进水电导率为1 860μS/cm条件下,平均脱盐率为74.8%,能耗1.42 kW.h/t;在平均进水电导率为3 862μS/cm条件下,平均脱盐率为72.4%,能耗1.86 kW.h/t,中试期间平均产水率为82.2%。电吸附技术对TDS、氯化物以及总硬度均有良好的去除效果,且能耗低、产水率高、操作简单,可用于城市污水再生水的脱盐处理。
