- Abstract:
-
Studied region was determined while characteristics of water system of river network area and pollutant emission was fully considered.Water quality of Sunan Canal and pollution load of corresponding affecting region were analyzed with single factor index method and equivalent pollution load method.Total pollution load of Sunan Canal including pollutant in and out of the studied region was calculated with flow proportion by water environment mathematical model of plain river network area.The results indicate that the 76.2% of 21 sections of Sunan Canal exceeded the water quality standards,the main factors of exceeding standard were NH3-N and TP.The quality of water in Changzhou and Wuxi sections is poorer than the other two.In the studied region,industrial point source has the largest pollution load contribution and domestic pollution source takes second place.Sunan Canal has total pollution load with COD 2.63 million tons,NH3-N 2614.3 ton and TP 316.63 ton,of which proportion of pollution load of intra-region is more than 79%.Intra-region pollution load is the main influencing source to water quality of Sunan Canal,Changzhou and Wuxi are the key regions to execute pollution control.
