- Title:
- Upgrading of Orbal Oxidation Ditch Based on Typical Southern China Wastewater Characteristics
- Keywords:
- Orbal oxidation ditch; SND; upgrading and reconstruction
- 摘要:
- 国内南方某污水处理厂一期工程设计规模为4×104 m3/d,采用奥贝尔氧化沟工艺,存在运行能耗高、药耗高、出水标准低等问题。对比了国外同类型氧化沟工艺,分析了同时硝化反硝化在奥贝尔氧化沟出现的机理及国内南方水质难以实现同时硝化反硝化的原因,提出了将表面机械曝气改为底部微孔曝气的改造方案。改造完成后,该污水厂运行成本大幅降低,节约生产成本267.68 万元/a,投资回收期为1.72 a,可为同类型污水厂的提标改造提供参考。
- Abstract:
- The design capacity of a wastewater treatment plant phase Ⅰ project in southern China is 4×104 m3/d. The Orbal oxidation ditch process is adopted, which has the problems of high operation energy consumption, high chemical consumption and low effluent standard. By comparing the same type of oxidation ditch processes abroad, this paper analyses the mechanism of simultaneous nitrification and denitrification (SND) in Orbal oxidation ditch and the reason causing inefficient simultaneous nitrification and denitrification of water quality in southern China. The transformation scheme of changing surface mechanical aeration into bottom microporous aeration is put forward. The operation cost after reconstruction is greatly reduced, the annual production cost is saved by 2.676 8 million yuan, and the payback period of reconstruction investment is 1.72 years, which provides a reference for the upgrading of similar WWTPs in China.
