十堰市神定河流域综合治理技术及工程实践

Comprehensive Improvement Measure and Engineering Practice for Shending River Basin in Shiyan

十堰市境内丹江口水库的五条入库河流污染严重,尤其是神定河水质长期不达标。针对神定河水质污染问题,国家正式批复《丹江口库区及上游十堰控制单元不达标河流治理方案》,要求对神定河实施综合治理。工程实施后,神定河入库水质明显好转,重点超标指标COD_(Cr)、NH_(3)-N、TP大幅下降。截至2020年,神定河入库口断面水质全年稳定达到Ⅳ类水。

The five major inflow rivers of Danjiangkou reservoir in Shiyan are seriously polluted, especially the water quality of the Shending River is not up to standard for a long time. Due to the water pollution of the Shending River and its requirement of the comprehensive improvement measure, the state has officially approved “the River Pollution Control Planning Scheme for the Upper Reaches of Danjiangkou reservoir in Shiyan”. After the implementation of the project, the water quality has been significantly improved, and the concentration of the major pollutants, COD_(Cr), NH_(3)-N and TP dropped substantially. By 2020, the water quality at the estuary of Shending River has been stable achieving the water standard Ⅳ throughout the year.
