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.
