Abstract

Abstract

Spectral characterization combined with multivariate statistical method was used to monitor and analyze the variation of organic matter concentration and spectral indexes in the inlet and outlet water of each treatment unit in the Yanlong project and Tongyu project in Yancheng. The results showed that the content of dissolved oxygen in the raw water of the Tongyu River and the Mangshe River was lower than that of the class Ⅲ in surface water quality standards in summer. In terms of organic concentration, a(254) was higher in raw water of Yanlong Lake, while COD_Mn and BOD₅ were higher in raw water of Tongyu River. The removal rates of COD_Mn, BOD₅, a(254) and a(355) in the pretreatment engineering of Yanlong Lake and Tongyu River were 4.19%, 37.50%, 1.55% and 10.31%, 23.49%, 24.88%, respectively. From the perspective of molecular structure, the pretreatment unit of Yanlong project and high-density sedimentation unit of Tongyu project had the most obvious changes on DOM, resulting in a decrease in DOM’s concentration and molecular weight, and a rise in the degree of polymerization of carbon atoms in benzene ring. The difference analysis showed that S_R and E₄₆₅/E₆₆₅ had a significant positive correlation with A₂/A₁ and A₃/A₁ at 0.01 level, while a(355) had a significant negative correlation with E₂₅₀/E₃₆₅ at 0.01 level. The research results provide a theoretical basis for optimizing the operation of micro-polluted water source pretreatment engineering and safety ensuring of urban drinking water supply.
