Investigation and Countermeasures of Water Pollution Sources of Yangzte River Basin in Chizhou City
摘要
Abstract
This study divided 6 control watersheds of important anabranchs for Yangtze river basin in Chizhou City based on digital elevation model (DEM) data and surface drainage.As the base line to 2015, the pollutant discharge amount from multiple sources into the river in each control watershed was investigated.The results showed that total amount of chemical oxygen demand(CODCr), ammonia nitrogen(NH3-N) and total phosphorus(TP) discharged into the river were reach to 18811.2, 2693.7 and 425.6 t/a, respectively.The primary pollution sources were agricultural source and rural life source.The quantity for pollutant on per unit area from 6 different control watersheds into the Yangtze river has a gradually increasing trend from the west to the east.At last, the causes of water environment problem were diagnosed and the fathering countermeasure were suggested pertinently.关键词
