【摘要】 以湛江市霞山区黑臭水体治理中暗渠清污分流为例，从分析暗渠及排口特性、水质黑臭成因出发，确定暗渠清污分流总体设计思路和技术路线，总结了排口摸查、一渠一策、分类截污、防海水倒灌、清淤、修复及设备材料选择与保护等设计要点。根据建设条件，因地制宜创新性地提出了缩小暗渠纳污面积、渠内包管清洗检修、交通干道下泵闸设置等工程难点解决方案，针对溯源摸查、施工质量安全、清污分流的重要性等问题提出思考，并对城市防洪和第二阶段水系治理工作提出了建议。本项目的实施实现了中心城区水系消黑初见成效的阶段性目标，为滨海城市暗渠化黑臭水体治理协同污水收集与处理系统提质增效提供了参考。更多还原

【Abstract】 Starting from the analysis of the characteristics of culverts and outlets and the causes of black and smelly water, the overall design idea and technical route of clean water and sewage diversion in culvert for the treatment of black and smelly water in Xiashan District, Zhanjiang City was determined,and the key points of design such as sewage outlets investigation, one-culvert-one-plan, classified sewage interception, seawater backflow prevention, dredging, remediation, selection and protection of equipment and materials were summarized. According to the construction conditions, innovative solutions for engineering problems were proposed, such as reducing the sewage receiving area of the culverts,maintenance and cleaning of pipes laid in the culverts, and setting up pump sluice under the traffic trunk road. The importance of tracing, construction quality and safety, clean water and sewage diversion and other problems were considered, and suggestions for urban flood control and the second stage water treatment were proposed. The implementation of this project achieved the phase goal of primarily eliminating black and smelly water in the central urban area, and provided a reference for improving the quality and efficiency of the treatment of black and smelly water in culverts combined with sewage collection and treatment system in coastal cities.更多还原
