Abstract

Through monitoring, investigation and analysis of water transparency, dissolved oxygen, chemical oxygen demand (COD), 5-day biochemical oxygen demand (BOD), total nitrogen and total phosphorus in Guanqiaojiao River, and based on "Environmental Quality Standard for Surface Water" (GB3838-2002), Single factor index method, comprehensive pollution index method and fuzzy mathematics evaluation method are selected to evaluate, analyze and compare the current situation of river inrush, and clarify the characteristics of water pollution in river inrush. The results showed that the water quality was judged as poor ⅴ by the pollution index method, and was judged as poor ⅴ by the fuzzy mathematical evaluation method. The water was seriously polluted by N, P and other nutrients, and the life pollution was rich in nutrients, which was in urgent need of treatment.
