Wastewater Reservoir Treatment Project in Sino-Singapore Tianjin Eco-City
The wastewater reservoir treatment project in Sino-Singapore Tianjin Eco-City, which last four years, is the first environment renovation project in China that performed advanced treatment to heavily contaminated sediment. TDC has completed four projects in succession for it: the expanded on-site pilot project, the sediment dewatering & volume reduction project, the sediment in-situ treatment project, and the Qingjinghu Lake deepening project. Adopting advanced water environment treatment technologies, TDC improved the wastewater reservoir in Hangu comprehensively and turned it successfully into a “clean water lake”, and established a virtuous circle between water resources and ecosystem, which set an example and could be used for reference for water environment treatment of polluted lakes and rivers in China.
