摘要：

The application of combined electrochemical and photochemical techniques for the degradation of real textile effluent is presented. It is demonstrated that the simultaneous use of both techniques, in conjunction with in situ generation of free chlorine and its subsequent photolysis, is a promising technique for removing color and chemical oxygen demand (COD) from effluents. Crucially, the combination of electrochemical and photochemical techniques leads to lower quantities of chlorine-containing degradation by-products being produced and no overall increase in toxicity. Over the treatment times studied, up to 65 % less chloride-containing degradation by-products are formed while at the same time greater rates of color and COD removal are achieved.
