高密度建成区水环境治理PPP项目技术优化策略

Technology Optimization Strategy of PPP Project for Water Environment Comprehensive Improvement in High-density Built-up Area

目前全国的黑臭水体治理已进入攻坚战阶段,高密度建成区合流制溢流污染的根治,仍是水环境治理领域的顽疾,也是打好污染防治攻坚战必须要攻克的堡垒。以武汉市黄孝河、机场河水环境综合治理二期PPP项目为依托,从风险管控的层面提出基于耦合模型分析系统目标可达性,优化集成技术措施,降低考核风险;从PPP项目物有所值的层面探索核心设备的选型论证,工艺设计方案的优化,以期实现政府方、社会资本方的双赢。高密度建成区水环境治理PPP项目技术优化策略,可为我国水环境治理PPP项目的建设单位、设计单位、运维单位提供借鉴。

At present, the treatment of black and odorous water body in China has entered the critical stage. The fundamental control of overflow pollution in high-density built-up areas is still an intractable problem of water environment improvement, and also a fortress that must be conquered in order to fight against pollution. Based on the second phase comprehensive water environment improvement PPP project of Huangxiao River and Jichang River in Wuhan City, this paper analyzes the system target accessibility based on the coupling model from risk management and control aspect, optimize the integrated technical measures, and reduce the assessment risk. It also explores the selection demonstration of the core equipment and the optimization of the process design scheme from the value for money perspective of the PPP project, so as to realize the win-win situation of both government and social capital. The technology optimization strategy of PPP project in high-density built-up area can provide reference for the construction, design, operation and maintenance units of PPP project in China.
