摘要
流域水环境治理常常由于主体众多、建设项目碎片化等原因无法达到预期效果,近年来许多城市采用PPP模式对流域水环境进行综合治理,为实现水环境综合治理效果,需要在项目初期采用系统化思维对各类子项进行统筹。结合沱江流域内江市域段水环境综合治理PPP项目实践,从宏观和微观层面探讨系统化实施方案编制的思路和要点,宏观层面以沱江流域内江段为研究对象,从大流域尺度分析现状存在的水环境治理、环境品质、管理机制等方面的问题,并提出对应实施方案,同时通过污染负荷和模型构建两种方式对预期效果进行评估;微观层面以具体黑臭水体河道(寿溪河)为研究对象,从小流域尺度分析现状存在的污水直排、农业面源和内源污染等问题,继而提出对应实施方案并进行效果评估,以期为国内其他城市开展流域水环境综合治理提供参考。
Due to many subjects and fragmentation of construction projects,watershed water environment management often failed to meet expectations.In recent years,many cities have adopted PPP mode to comprehensively manage the watershed water environment.In order to achieve the effect of comprehensive management of watershed water environment,it is necessary to adopt systematic thinking to coordinate each sub-project at the beginning of the project.Combined with the practice of the PPP project for comprehensive management of water environment in the Neijiang section of the Tuojiang River watershed,the ideas and key points of the systematic implementation scheme are discussed from the macro and micro levels.On the macro level,taking Neijiang section of the Tuojiang River watershed as the research object,the existing problems including water environment governance,environmental quality,and management mechanism were analyzed from the large watershed scale.And the corresponding implementation schemes were put forward.The expected effect is evaluated by pollution load and model construction.On the micro level,taking Shouxi River as the research object,the problems of direct sewage discharge,agricultural non-point source and endogenous pollution in small watershed scale were analyzed.The corresponding implementation schemes were proposed,and the implementation effect evaluation was carried out.Thus,it can provide reference for other cities in China to carry out comprehensive water environment management.
