Abstract:

Taking a wastewater treatment plant，in Ruian City as example，technological introduction and operation data analysis have been made. One of the problems encountered in the multi-mode A²/O oxidation ditch process in actual running is that the removing result of total phosphorus isn’t good. Better ways having been tried for improvement，satisfactory results are finally obtained.

Key words: multi-mode A²/O oxidation ditch process, total phosphorus, multi-dosing, efficient sedimentation

摘要：

以瑞安市某污水厂为例,进行工艺介绍及运行数据分析,总结出多模式A²/O氧化沟工艺在实际运行过程中遇到的问题之一是除总磷效果不理想,并尝试通过改进工艺找出改善途径,最终取得了满意的效果。

关键词: 多模式A²/O氧化沟工艺, 总磷, 多点加药, 高效沉淀
