摘要:
上海市竹园第二污水处理厂现有处理设施不能适应新的环保要求，需进行提标改造。鉴于厂内用地紧张，采用减量升级方案，处理规模由50×104 m3/d减量为30×104 m3/d，原有设施按照30×104 m3/d规模提标改造。在水质提标改造中，充分利用现有设施，维持现有生物反应池主体框架结构不变，通过调整水流方向，将原有闭式双泥龄A/O工艺调整为强化脱氮除磷的AAO工艺。考虑到生物池出水水质及厂内集约化设计，新增微絮凝＋过滤的深度处理工艺，保证出水水质稳定达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级A标准。在除臭提标改造中，对大跨度的生物反应池创新采用可移动式盖板加盖，最大限度减少对现有结构的影响，方便运行管理，并增设以生物滤池为主体的多级除臭设施以达到上海市最新地方标准排放要求。
Abstract:
The existing facilities of Zhuyuan No.2 wastewater treatment plant in Shanghai can not adapt to the new environmental requirements and the effluent quality needs to upgrade to first grade A standard. A reduction and upgrading scheme was adopted in the project due to limited construction area in the plant. The treatment capacity was reduced from 50×104 m3/d to 30×104 m3/d, and the original facilities were upgraded according to the treatment capacity of 30×104 m3/d. In the upgrading project, the existing facilities were fully utilized to maintain the existing biological tank main frame structure unchanged. By changing the water flow direction, the original closed double-sludge A/O process was adjusted to an enhanced nitrogen and phosphorus removal AAO process. Considering the bioreactor effluent quality and intensive design, an advanced treatment process consisting of micro-flocculation and filtration was newly built to ensure the effluent quality meeting first grade A limitations of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). In the deodorization upgrading project, the biological tank was covered with a moveable cover plate to minimize the impact on the existing structure and facilitate the operation and management. Multistage deodorization facilities with biological filter as the key process were constructed to meet the latest local standard emission requirements of Shanghai.
