摘要:
紧邻水源保护区的沿江城市截污干管改造如何避免污水溢流和改善水环境质量是此类工程的设计难点。以泸州二道溪污水处理厂截污干管改造为例，创新性地提出了截污干管功能复线方案，通过在新旧截污干管间预留连通管和开闭闸阀的方式充分利用旧管的容积，保证新管在流量过载和检修时，污水不间断、不溢流；还增设了排泥事故多功能检修井，避免泥渣直排入江，改善了沱江水环境质量，提升了工程的环保性和经济性。此外，该项目设置了一座10×104 m3/d的污水泵站，其穿越滨江公园、西南商贸城、老旧小区及工房拆迁区等施工环境敏感区的控制性因素、施工方式，以及新旧截污干管和污水泵站的运行模式等可为后续相似排水工程项目提供参考。
Abstract:
How to avoid sewage overflow and improve water quality is the difficulty of engineering design for reconstruction of sewage interceptors in cities along the river close to water source protection areas. Taking the reconstruction of sewage interceptor of Luzhou Erdaoxi wastewater treatment plant (WWTP) as an example, this paper innovatively puts forward the multi-functional line scheme of sewage interceptor, which makes full use of the volume of the old pipe by reserving the connecting pipe and the gate valve between the old and new sewage interceptors, so as to ensure that the sewage will not be interrupted and overflow when the new pipe is overloaded and overhauled. Furthermore, a multifunctional manhole for sludge discharge accident is also added to avoid sludge directly discharged into the river, which enhances environmental protection and economy. In addition, a 100 000 m3/d sewage pump station is set up in this project. The control factors and construction methods of the project crossing the construction environment sensitive areas such as Binjiang Park, Southwest Trade City, old community and workshop demolition area, as well as the operation mode of the old and new sewage interceptors and sewage pump stations, can provide reference for subsequent similar drainage projects.
