Water Quality Analysis and Pollution Prevention and Control Suggestion of Jiulongjiang River West Branch Shangban Section

该文利用近3年九龙江西溪上坂断面水质监测数据,依照水环境质量标准进行分析,采用单因子评价对水环境质量进行了评价。结果表明:近年来西溪上坂断面水质均值达标,但单月水质仍然不稳定,其中首要超标项目已由氨氮转化为溶解氧。对此,该文综合漳州市实际情况进行分析,并提出对策为稳定龙文区上坂断面水质达标提供参考。

According to the water environment quality standard and the water quality monitoring data of Shangban section of the west branch of Jiulong River in recent three years,the water environment quality was evaluated by single factor evaluation method.The results show that the average water quality of Shangban section of the west branch reaches the standard in recent years,except that the water quality is still unstable in a single month.The primary over-standard items have been converted from ammonia nitrogen to dissolved oxygen.This paper analyzes the actual situation in Zhangzhou City,and puts forward countermeasures to provide reference for stabilizing the water quality of Shangban section in Longwen District.
