沉淀池排泥水中二氯乙酰胺前体物研究
Research on precursor substances of dichloro-acetamide (DCAcAm) in sludge water
摘要
Abstract
In order to obtain the characteristics of main precursor material of dichloro-acetamide in sludge water.We explored the relationship between the ratio of dichloro-acetamide (DCAcAmFP) and DON and DON/DOC in this study.Results show that the DON value in sludge water (0.3 ～ 0.6 mg/L) is higher than the corresponding value in raw water (0.2 ～ 0.4 mg/L),and the hydrophilic small molecular weight accounts for the majority,DcAcAmFP reaches 5 ～ 8 μg/L.DCAcAmFP has a certain correlation with DON (R2 =0.623).There is a strong linear correlation between the ratio of DCAcAmFP and DON/DOC (R2 =0.868),which means the main precursor of dichloro-acetamide is amino acid and protein hydrophilic small component nitrogen-containing organic matter.关键词
