建宁港水环境综合整治成效及探讨

Comprehensive Improvement and Discussion of Water Environment of Jianning Port

建宁港是横穿株洲市老城区的一条主要河流,水质受沿线居民生产生活影响大,污染较重。当地政府为改善建宁港水质采取了专项治理,采用水质标识指数法,对整治前后港水水质进行对比。结果发现整治后港水水质有明显提升,黑臭现象发生频率减少,总氮和氨氮指标有较大幅度下降,但整治后港水水质仍没有达到水质考核目标要求。依据前期整治措施和成效,为下一步防治工作提出了建议。

Jianning port is a main river across the old urban area of Zhuzhou.The water quality was greatly affected by the production and life of the residents along the line.The special measures were adopted to improve the water quality of Jianning port by the local government.The water quality identification index method was used to compare the water quality before and after remediation.The results showed that the water quality has been obviously improved.The frequency of black-odor was reduced,and the concentration of the total nitrogen and ammonia nitrogen indexes was greatly lowered,but the water quality still didn't met the requirements of the water quality assessment target.Suggestions for further prevention and control were put forward based on the previous regulation measures and effects.
