The Current Situation of Water Pollution of Kui River(Xuzhou Section) Based on Multivariate Statistical Analysis
摘要
Abstract
Kui River is an important river in Xuzhou .In recent years ,the pollution of the river is more serious because of the free discharge of sewage and industrial wastewater .In this paper ,the water quality of the 7 monitoring sections of the Kui River (Xuzhou section) was analyzed ,and the statistical analysis was carried out using the cluster analysis and principal component analysis .The results showed that :(1)the turbidity value of seven monitoring sections changed from1 .05 to 1 .99NTU ,pH 7 .23~7 .83 ,dissolved ox‐ygen 0 .48~2 .98mg/L ;(2)higher content of COD ,T P and nitrate nitrogen ,seven section overall belonged to class V~inferior V class of water ;(3)clustering analysis showed that seven section could be divided for urban and rural combination section and rural section;(4)principal component analysis showed that eu‐trophication problem of Kui River was serious and the phosphorus was the main pollution factor ,organic matter and nitrogen pollution was also serious .关键词
