隧洞排水处理系统设计与运行管理OA

Guangxi Water Resources Allocation Project around Beibu Gulf primarily utilizes tunnels to achieve harm-less passage through environmentally sensitive areas,including water source conservation ecological protection zones,drinking water source protection areas,and provincial-level important wetlands.Certain tunnel sections pass through fault fracture zones with abundant groundwater,resulting in considerable construction drainage volumes.Consequently,the treatment of tunnel drainage during construction has become a critical consideration for the proj-ect.Based on experience from major water conservancy projects in Guangxi,this paper summarizes the existing problems and proposes a solution emphasizing both design and management.Horizontal-flow coagulation sedimenta-tion process is adopted for tunnel wastewater treatment,a standardized construction management system for tunnel drainage is established,and the operational and maintenance requirements for tunnel wastewater treatment are for-mulated,so as to ensure stable compliance with discharge standards,and contribute to the development of an ecolog-ically-friendly project.
