- 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.
