摘要

文中以连云港近岸海域所在区域某污水处理厂为例,根据尾水排放条件和近岸海域的水文条件,采用二维潮流数学模型来进行水环境影响预测分析。结果表明,随着扩建工程实施,COD_(Mn)浓度能够满足二类海水水质限值要求,无机氮、活性磷酸盐浓度已轻微超二类海水水质限值。对污水厂扩建工程尾水排放中TN、TP的水质排放要求起到了十分重要的作用。
        In this paper, a sewage treatment plant in Lianyungang coastal waters was selected as an example, and according to tailwater discharge conditions and hydrological conditions of coastal waters, a two-dimensional tidal flow mathematical model is adopted to predict and analyze the water environmental impact caused by sewage discharge. The results showed that, with the implementation of the expansion project, the concentration of COD_(Mn) can meet the class Ⅱ seawater water quality standard, while the concentration of inorganic nitrogen and active phosphate slightly exceeds the class Ⅱ seawater water quality standard. This study plays an important role in improving the water quality requirements of TN and TP in sewage discharge of the sewage plant expansion project.
