摘　　要：试验采用Cu2+-Ce4+双元素复合改性负载型TiO2复合纳米微粒光催化剂处理农药废水,通过对载体的煅烧温度、pH、反应时间、元素量等指标分析了双元素改性过的TiO2光催化剂对自配得农药废水的色度和CODCr的去除的影响。试验结果表明:原水样经过Cu2+-Ce4+双元素深度改性的TiO2光催化剂处理后出水水质色度去除率为98.9%,CODCr去除率70.3%,改性效果明显。Cu2+-Ce4+ dual-element composite modified nanoparticles supported TiO2 was used as composite photocatalyst to treat pesticides wastewater.Effect of calcination temperature of the carrier,pH,reaction time,element dosage on removal rates of pesticides wastewater color and CODCr with the two-element modified TiO2 photocatalyst was analyzed.The results show that: after treating original water sample by Cu2+-Ce4+/TiO2 photocatalyst,color removal rate is 98.9%,CODCr removal rate is 70.3%,the modification effect is obvious.
