Water Pollution Assessment and Dredging Effects of the Nanfei River in China
Abstract:
This paper employed the water quality monitoring data of Nanfei River to analyze the water pollution status, and to contrast the water quality change of the river section which has been dredged. We selected TN, TP, COD and NH3-N as the evaluation factors to study the spatial distribution. Results showed that TN concentration was seriously higher than the upper limit of surface water standard class V, and TP and COD values were in class V, and NH3-N concentration was in class III. Refer to previous water quality monitoring data, dredging projects of Nanfei River worked significantly on TP, COD and NH3-N removal, while TN concentration was 5 times more than before.
