摘要
从有机物性质角度对二氯乙腈前体物进行分析,探究太湖流域某深度处理水厂各工艺单元对二氯乙腈生成势的去除。试验结果表明,水厂原水中亲水性有机物、分子量小于1 k Da或大于10 k Da的有机物是二氯乙腈的主要前体物。深度处理工艺水厂对二氯乙腈前体物的去除率高达79.3%,其中O_3/BAC工艺的贡献率远高于常规工艺。
The properties of organic matter in raw water were explored to identify the precursors of dichloroacetonitrile(DCAN).In addition,the removal efficiency of DCAN formation potential in the drinking water treating process of an advanced waterworks around Taihu Lake was also investigated.Results show that hydrophilic organic matter and organic matter with molecular weight<1 kDa or>10 kDa were main precursors of DCAN.The removal efficiency of DCAN precursors by the advanced water treating plant was as high as 79.3%and the contribution rates of O3/BAC was much higher than the conventional process.
