摘要
将物理化学预处理与膜分离技术深度处理结合应用于工业废水处理,可使其中的Cr6+<0.5mg/l,Zn2+<20mg/l,pH6~9。用膜分离技术处理造纸废水可回收其中的木质素和糖份,回收率均为60%左右。
By applying the physico-chemical treatment and membrane separating technique to the industrial waste water treatment,the Cr 6+ in the waste water could be less than 0.5mg/L,the Zn 2+ could be less than 20mg/L and the PH could be from 6 to 9.The wood cellulose and sugar in the waste water from pulp and paper mills could be recovered and the recovery rate is about 60 percent.
