摘 要:<正> To study the feasibility of treated water being used as rinsing water with CP/ED (chemical precipitation/ electrodialysis) system, the relation between concentration of Cr (Ⅵ) and conductivity of water is investigated, the effect of electrodialysis (ED) for different wastewater is also studied. And several parameters of importance that are relevant to the process are identified. Analysis of ICP (Inductively coupled plasma) and IC (Ion chromatography) shows that the main reason of conductivity increase in CP treated water is the increase of Na+ and Cl- ions. The 93.8%-100% of ions from wastewater both in ED and CP/ED systems was removed successfully. The results of experiments indicate that the CP/ED system is a feasible method for electroplating wastewater treatment, the CP/ED system used as a way of wastwater is not only in favour of environment, but also economic beneficial to achieve.
