摘要
研究了孔径分别为0.2、0.5μm的陶瓷膜对电镀废水的微滤行为,考察了温度、错流速度以及跨膜压差等因素对膜通量和镍截留率的影响。研究结果表明,当错流速度维持在3.0 m3/h,跨膜压差为1.2 MPa,温度为35℃时,能获得较好的膜通量和经济效益,此时镍离子的回收率为93.64%。
The microfiltration behavior of electroplating wastewater containing nickel ions are studied by using ceramic membranes with average pore diameter of 0. 2 m and 0. 5 m,respectively. The effects of temperature,cross-flow velocity and trans-membrane pressure on permeate flux and nickel rejection are investigated. The results show that,when the flow velocity is maintained at 3 m3/h,the transmembrane pressure difference is 1. 2 MPa,the temperature is 35℃,better membrane flux and the economic benefit can be obtained. The recovery rate of the nickel ion is 93. 64%.
