Study on the Pollution Load of Minjiang River in Fuzhou Section |
| |
Abstract: | With the help of GIS and based on the investigation and analysis of the pollution sources, a study of pollution load of Minjiang River in Fuzhou section over the watershed scale was carried out. The assessment of pollution load was mainly based on COD and NH3 - N index, by which the pollution sources and ratios were determined. Results indicated that in the study section, 9 371.75 t COD and 992. 63 t NH3 -N were discharged into Minjiang River, mainly came from industrial sources and ur- ban life. The most polluted watershed was inland rivers in Fuzhou City which accounted for 34. 4% of COD discharge and 61.3% of NH3 - N discharge. Point source pollution was the main pollution source in inland rivers, and in the north branch of Minjiang River and Moxi river, non-point source pollution was the main pollution source in the main stream of Meixi River as well as in the main stream of Dazhangxi River . |
