In 2025, multiple projects in the field of water treatment in China will open for bidding, and various enterprises will actively compete. The dust of many major projects will be settled. Below is a detailed introduction to these winning bids.
Winning the bid for Zhangji Coal Mine Water Treatment Project in High Energy Environment
As a member of the consortium, High Energy Environment has successfully won the bid for the Zhangji Coal Mine Phase II Mine Water Treatment and Resource Utilization Project, with a bid amount of 187 million yuan. The project has a processing capacity of 14000m ³/d, and the produced water not only meets the self use of the mine, but also the surplus will be transported to Xieqiao Power Plant for full reuse. At the same time, the heat source generated by the carbon dioxide cooling project is utilized to evaporate and crystallize the concentrated high salt wastewater, achieving the resource utilization of wastewater and salt, and achieving near zero discharge of wastewater. This is of great significance in alleviating the contradiction between mining production, water supply, and ecological protection.
Entrepreneurial Environmental Protection Leading Wuhu Sewage Treatment Project
On January 2nd, Entrepreneurial Environmental Protection, in collaboration with China Railway Shanghai Engineering Bureau Group Co., Ltd. and Anhui Shunyu Water Affairs Co., Ltd., won the bid for the franchise project of Wuhu Binjiang Sewage Treatment Plant Phase II. The project adopts the BOT franchise model, with a construction scale of 60000 m ³/d and a total investment of 277 million yuan. The government investment support during the project construction period is 149 million yuan, and the franchise period is as long as 40 years. Afterwards, the project company will sign relevant franchise agreements with the Wuhu Housing and Urban Rural Development Bureau.
The first implementation of CREATE technology by Shouchuang Environmental Protection Group
As a process package provider, Shouchuang Environmental Protection Group has signed a contract for the upgrading project of facilities and equipment at Dingqiao Sewage Treatment Plant in Haining City, Zhejiang Province. This marks the first time that the CREATE aerobic granular sludge technology independently developed by Shouchuang Environmental Protection Group has been implemented and applied. This project will carry out in-situ transformation of SBR biological treatment technology in the first phase of the sewage treatment plant, increasing the treatment capacity of the biological treatment section from 40000 tons/day to 70000 tons/day. The investment cost for expanding the capacity of 30000 tons per day in this project is lower than that of building a new sewage treatment plant of the same scale, and there is no need for new land acquisition. Only the equipment and facilities of the original SBR tank structure can be upgraded and expanded, which has extremely high economic and environmental value.
