摘　　要：厦门市埭头溪流域属沿海季节性雨源型城市感潮河流,存在旱天污水直排、雨天污水溢流、生态基流匮乏、底泥淤积等诸多水环境问题,导致其水质恶化严重,水生态系统受损,水环境容量不足。为彻底解决埭头溪流域水环境问题,在进行污染物来源量化分析的基础上,从减少入河污染和提升自净能力两方面着手,提出了控源截污、内源治理、活水提质、生态修复和旁路净化的治理方案,构建了从源头到末端的水环境综合治理体系,探索了沿海季节性雨源型城市感潮河流水环境综合治理及规划设计的思路。该工程总投资为344 556万元,现已完成包括污水厂扩建、截污管道、底泥治理、补水管线及生态修复在内的多项工程,水环境治理已取得显著效果。Xiamen Daitouxi is a coastal and seasonal stormwater-source urban tidal river, which has many water environment problems, such as direct discharge of sewage in dry days, overflow of sewage in rainy days, lack of ecological base flow, sediment deposition and so on, resulting in serious deterioration of its water quality, damage to the water ecosystem, and insufficient water environment capacity. In order to thoroughly solve the water environment problems in the Daitouxi watershed, based on the quantitative analysis of the pollutant source, from the two aspects of reducing the influent pollution and improving the self-purification capacity, the treatment schemes of source control and interception, endogenous treatment,living water quality improvement, ecological restoration and bypass purification are put forward, and a comprehensive treatment system of water environment from the source to the end is constructed. This paper explores the ideas of comprehensive management, planning and design of river water environment in coastal and seasonal stormwater-source cities. The total investment of the project is 3 445.56 million yuan.A number of projects including sewage plant expansion, sewage pipelines, sediment treatment, water replenishment pipelines and ecological restoration have been completed, and remarkable results have been achieved in water environment treatment.
