大型污水厂不停产提标改造设计
- Title:
- Design of a Large Wastewater Treatment Plant Upgrading and Reconstruction Project without Stopping Production
- 摘要:
- 成都市第九再生水厂处理规模100×104 m3/d，原采用以多模式A2O+纤维滤池为主体的处理工艺，提标改造工程需在不停产的情况下将出水标准由一级A标准提升至《四川省岷江、沱江流域水污染物排放标准》（DB 51/2311—2016）。通过综合分析污水厂现状构筑物及实测进、出水水质，确定了在二沉池后设置高密度沉淀池及反硝化深床滤池的工艺方案，其中反硝化深床滤池采用新建+改造相结合的方式建设，解决了厂内用地紧张的问题。项目建设过程中采取分阶段实施及不停水碰管等方式，成功实现了不停产提标改造。项目投产后，出水水质稳定优于排放标准。
- Abstract:
- The original treatment process of Chengdu No.9 reclaimed water plant with treatment scale of 100×104 m3/d consists of multi-mode A2O and fiber filter. The upgrading and reconstruction project needs to upgrade the discharge standard from first level A limit to the limit specified in Discharge Standard of Water Pollutants in Minjiang River and Tuojiang River Basin in Sichuan Province (DB 51/2311-2016) without stopping production. The design selected the scheme of setting high-density sedimentation tank and denitrification deep bed filter after the secondary sedimentation tank through the comprehensive analysis of the current structures of the wastewater treatment plant and the measured influent and effluent quality, in which the denitrification deep bed filter was constructed by a combination of new construction and reconstruction, thus solved the land shortage problem. In the construction process, the project adopted the methods of phased implementation and non-stop production pipe-touching construction techniques, and successfully realized the upgrading without stopping production. The effluent quality is stable and better than the discharge standard after the project is put into operation.
