Abstract

Yunnan Province is endowed with abundant water systems and resources. In recent years, with urbanization, human population, social and economic progress fastening, water environment problem is becoming increasingly serious. Therefore, this study proposes the coordinated development of social economy and water environment in Yunnan Province. According to the situation of wastewater discharge in Yunnan Province, the main sources of wastewater discharge and the main factors affecting urban wastewater discharge in recent years are analyzed. Statistical analysis results show that wastewater discharge in Yunnan Province in the past five years mainly came from domestic wastewater (8,891,023,700 tons), followed by industrial sewage (1,984,587,500 tons). Through cluster analysis, 16 cities in Yunnan Province were finally divided into four categories, with Kunming as category 1, Qujing as category 2, Lijiang, Nujiang, Diqing, Baoshan, Chuxiong, Lincang, and Xishuangbanna as category 3, and other cities category 4. In recent years, wastewater discharge in Kunming and Qujing City has been on the rise, probably due to large population density and high demand for domestic water, the concentration of high water-consuming industries such as mining and metallurgy, and defects in wastewater and sewage treatment technology.
