污水处理厂多模式生物反应池的设计应用分析
- Title:
- Design and Application Analysis of Multi-mode Biological Reaction Tank in a WWTP
- 摘要:
- 某污水处理厂二期工程设计规模为5×104 m3/d。设计采用多模式生物反应池，可按照A-A2/O、倒置A2/O、Bardenpho、侧流硝化和侧流污泥水解等多种模式运行。实际运行结果表明，在未投加碳源和化学药剂的情况下，该工程出水水质可以达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）的一级A标准，后续还有进一步提升的空间。
- Abstract:
- The design scale of the second phase project of a wastewater treatment plant (WWTP) is 5×104 m3/d. A multi-mode biological reaction tank is adopted in the design and can operate according to various modes such as A-A2/O, inverted A2/O, Bardenpho, side-stream nitrification, side-stream sludge hydrolysis and etc. The actual operation results show that the effluent quality of the project can meet the first level A criteria of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) without adding carbon source and chemical agents, and could be better for further improvement.
