Abstract: In order to explore a set of scientific and effective methods suitable for water environment comprehensive treatment in high-density built-up areas, this paper analyzed and summarized the successful practice of water environment treatment mode in Bao′an District, Shenzhen, from the aspects of treatment measures and administrative management.The results showed that the comprehensive treatment of urban water environment should be based on the top-level design of local government, adhere to the governance principle of "system + source",follow the technical route of "treatment plant, network, river and source",extend from the end interception to the original source, from the main river to the tributary system.Every black and odorous water body should be precisely controlled under the whole river basin management.Meanwhile, it is necessary to adhere to governance strategies that the management should be taken as significant as building.Then water environment treatment should adopt simple and efficient water control mode of Engineering Procurement Construction(EPC) and management mode of "1+1+4",which can fully take the advantages of participating units, such as central enterprises, in terms of talents, technologies, experiences and equipment, ensuring the successful completion of engineering under tight schedules and heavy tasks.This mode is not only to realize the whole process tracking management, but also easy to control the project schedule, project quality and water quality goals and other elements as a whole.The research results can provide reference for similar water environment management.
