唐山市近岸海域入海排污口监管对策研究

“十三五”期间，唐山市加大重点流域和海域综合整治力度，入海污染物总量大幅减少，近岸海域优良水质面积比例呈上升趋势，但入海排污口数量仍然较大，陆源污染物通过入海排污口进入海洋，对海洋生态环境质量产生一定影响。唐山市作为渤海入海排污口排查整治试点城市，通过总结排查整治方法和监管措施经验，提出明确排污口管理责任、推进排污口分类整治、加强监管能力建设、开展排污口动态更新等监督管理措施建议，为渤海入海排污口全面排查整治提供可复制、可推广、可借鉴的排污口排查整治经验。

Study on the supervision countermeasures of sewage outlets into the sea near the coast of Tangshan city

During the 13th Five-Year Plan period, the major river basins and sea areas were treated with comprehensive improvement in Tangshan city, the total amount of polluting emission discharged into the sea decreased significantly, and the area ratio of high quality water in off-shore area showed an escalating trend, but the number of off-shore vents were still large, and the land-based pollutants entered the sea through these vents, which caused a certain impact on the quality of marine ecological environment. As a national pilot city for the investigation and remediation of sewage outfalls into the Bohai Sea, the government of Tangshan puts forward some suggestions on supervision and management measures, such as clarifying the management responsibility of sea outfall, promoting the capacity of classification and regulation of sea outfall, strengthening the construction of supervision ability, and carrying out the dynamic update of sea outfall, by summarizing the experience of investigation and regulation methods and supervision measures, so as to provide replicable, propagable and referential experience for the nationwide comprehensive investigation and regulation of Bohai Sea outfall.
