Project background

In accordance with the minutes of the meeting of the Coordinating Committee on Research and Solution of Water Environment Control in Chaoyang District, held on November 10, 2016 by the relevant departments of Chaoyang District, Beijing, it was agreed that temporary pollution interception and additional temporary treatment facilities should be adopted for the black and odorous water bodies and village sewage outlets within the jurisdiction.

In mid-November 2016, the temporary treatment project of black and odorous water interception and village sewage discharge in central city was officially launched. Entrusted by the North Drainage Group, Beijing Green Heng Technology Co., Ltd. has set up temporary sewage treatment stations in 11 places, such as Xigangou, Laohe Bay, Grassland, Youth Lugou and Shawo Village North, to treat the effluent from each sewage outlet.

Project overview

All treatment stations adopt standardized and serialized GreenEver high-efficiency non-power sewage purification equipment. Its core is self-circulating high-density suspended sludge filtration technology independently developed by Greenhouse Technology. This technology has been listed in the recommended technology of "Technical Guidelines for Urban Black and Odorous Water Treatment - Drainage, Pipeline and Inspection Well Treatment" by the Ministry of Housing and Construction.

The whole site was completed and put into operation within two months after the start of the project. As of April 30, 2108, the cumulative amount of treated water was about 31.6 million M.³，The removal rate of COD and SS and TP by the treatment station is more than 50% and 80%, which greatly reduces the pollution degree of water bodies and contributes to the protection of the sustainable development of the green ecology in the capital.
