Luo Y., Liu X., Chen Q., Dong N., Wei X., Huang A., 2016, Analysis on Influencing Factors of Water Quality of Qingshui River System in Zhangjiakou City, Chemical Engineering Transactions, 55, 487-492.
Taking the Zhangjiakou section of Qingshui river basin as the research object, the influencing factors of river basin water pollution were analyzed. Using the analytic hierarchy process to establish the evaluation index system of water quality and safety, and using the rigor of logic and the comparison of the two factors to calculate and analyze the weight of each influencing factor, and then evaluate the main influencing factors of Qingshui River water quality. : 18 water quality indicators in Qingshui water quality safety evaluation system, the top five indicators are the straight row of domestic sewage, living pollution, river water temperature gradient, nitrification, nitrification bacteria activity, initial rain inclusion Coastal pollutant content.
