摘要
以钛酸丁酯为原料,用醇盐水解法制备出具有较强光催化活性的纳米TiO2粉体,该粉体可有效去除酿酒工业废水中的COD;高浓度的酿酒工业废水经纳米TiO2二次降解后,其 COD值可降至601 mg/L,去除率达90％以上,处理后水的COD值低于行业排放标准三类水质 (COD:1000 mg/L)的限值。
Butyl titanate was used as raw materials to produce nanometer TiO2 powder with strong photocatalysis activity by alkoxide hydrolysis method. Such powder could effectively eliminate COD in wine industry waste sewage. COD value of high concentration wine industry waste sewage treated by quadratic degradation by nanometer TiO2 dropped to 601mg/L with the removal rate above 90 %. And COD value of the treated sewage was less than the third-grade sewage limit COD value of industry discharge standards. （Tran. by YUE Yang）
