Research on Characteristics and Control Measures of Surface Water Pollution in Industrial City Agglomeration
To explores the characteristics of surface water pollution in industrial urban agglomerations and study governance strate-gies,this study selects the Lanxi Industrial City Cluster in the upper reaches of the Yellow River Basin as the research area.Multiple sampling points were used to measure the pollution parameters of water quality samples to reveal pollution characteristics,and study gov-ernance strategies.The surface water pollution in industrial urban agglomerations is significant,with the main pollutants COD,SS,NH4+-N,Cu,Cr,and Pb having higher concentrations in industrial areas than in agricultural areas.At the beginning of the rainfall,the con-centration of pollutants was high and gradually stabilized.The scouring effect of heavy metals is strong,especially in industrial areas.The paper proposes comprehensive control measures for pollution sources and emission characteristics.The results indicate that there are vari-ous pollutants present in the surface water environment of industrial urban agglomerations,exhibiting complex pollution characteristics.Based on this,comprehensive water pollution control measures are proposed.
