摘　　要：基于源头分析的污染负荷估算工作,可对城市河道污染治理顶层设计的方案思路及工程措施提供重要的科学依据。针对无锡市城中槐古圩片区河道治理工程,在对圩区污染源分类解析的基础上,参考数值模型和经验公式,归纳出一套适用于苏南典型城市河网污染负荷的快速估算方法。结果表明,圩区内骨干河网COD、NH_(3)-N,TP入河总量分别为176.81、102.81、7.80 t/a,点源、面源、内源污染负荷分别为120.98、105.39、91.48 t/a,其中42.07%的污染来源于点源排放,梁溪河流域污染总量为141.76 t/a,贡献占比率高达到49.31%。The pollution load estimation based on source analysis can provide top-level design guidance for urban river management and scientific basis for formulating engineering measures.Taking Huaigu basin in Wuxi City as the research object,based on the classification and analysis of pollution sources,numerical models and empirical formulas were used to summarize a set of rapid estimation methods applicable to river network pollution load in the typical cities in southern Jiangsu Province.The results show that the total amount of COD,NH_(3)-N and TP inflow into the backbone river network in the district is 176.81,102.81,and 7.80 t/a,respectively.The point,surface and endogenous pollution loads are 120.98,105.39 and 91.48 t/a,and 42.07%of the pollution originated from point sources.The total pollution in Liangxi River Basin is 141.76 t/a,and the contribution ratio accounted for 49.31%.
