摘　　要：对光催化剂TiO2降解电镀污水中COD值进行了研究。结果表明,在380 nm光照条件下,100 mL电镀污水溶液,其COD为151 mg/L,降解COD较优条件是:0.3 g TiO2光催化剂,pH值至2,反应60 min。该方法降解COD成本较低,效果较好。The degradation of electroplating wastewater COD with-photocatalyst was studied. The result showed that in the conditions of 380 nm light,the optimum conditions of the degradation of electroplating wastewater which the COD value of 100 mL electroplating waste water is 151 mg/L, react 60 min with 0.3 g photocatalyst TiO2, adjusting the pH to 2. This method costs lower and the effect is better.
