The main research achievements and application of the “Comprehensive Demonstration of Wastewater Pollution Control and Ecological Restoration in Tianjin Binhai Industrial Belt” Project in the National Water Pollution Control and Treatment Science and Tec

针对天津滨海工业带当前面临的有限的水环境容量、水生态承载力与密集的工业排放强度之间的矛盾,部署了国家水体污染控制与治理科技重大专项项目“天津滨海工业带废水污染控制与生态修复综合示范”。依托该项目,开展了天津滨海工业带水生态环境精细化管理、“减排-扩容-保安全”模式下的工业园区高标准排放、突发水环境风险应急管控等研究工作,集成构建了水资源、水环境、水生态、水安全统筹兼顾的天津滨海工业带“负荷零增长”水环境管理技术体系、滨海工业带工业园区高标准排放与生态修复技术体系和“查-控-处”一体化的水环境风险管控体系。依托该项目研发的技术体系在天津滨海工业带进行了示范与应用,实现了滨海工业带水生态环境空间管控、水质目标精细化管理和基于差异化区域总量的排污许可管理等核心管理技术的有效衔接;在国内首次系统解决了滨海工业带工业园区污水处理厂最严格的准IV类排放稳定达标问题,首次提出了统筹初期雨水强化预处理的滨海工业带多功能人工湿地协同构建模式;建成了国内首个大型环境应急装备物资库与风险管控平台,形成了系统化应急技术与装备体系,填补了天津滨海工业带环境风险管控的空白。

In view of the contradiction between the limited water environment capacity, water ecological carrying capacity and intensive industrial discharge intensity currently faced by Tianjin coastal industrial belt,the national major science and technology special project of water pollution control and treatment "Tianjin coastal industrial belt wastewater pollution control and ecological restoration comprehensive demonstration"was deployed. Based on the project, it has carried out research work in Tianjin coastal industrial belt, such as refined management of water ecological environment, high-standard discharge of industrial parks under the mode of emission reduction-water capacity expansion-water environment security and emergency management and control of sudden water environmental risks, etc. The "zero load growth" water environment management technology system, which integrated water resources, water environment, water ecology and water security, the high-standard discharge and ecological restoration technology system, and "integrated water environmental risk control system of "investigation-control-discipline", have been constructed. The technology system developed by this project has been applied in Tianjin coastal industrial belt, realizing the effective connection of core management technologies such as spatial control of water ecological environment, refined management of water quality objectives and sewage permit management based on differentiated regional total amount in coastal industrial belt. For the first time in China, it has systematically solved the strictest quasi class IV discharge standard of the wastewater treatment plant in the coastal industrial zone. The cooperative construction mode of multi-functional constructed wetland in coastal industrial zone was proposed for the first time. The first large environmental emergency equipment material warehouse, and risk management and control platform in China have been constructed, forming a systematic emergency technology and equipment system, filling the blank of environmental risk management and control in Tianjin Binhai Industrial Belt.
