杭州四堡污水处理厂曝气系统改造效益分析

摘要

杭州市四堡污水处理厂采用A/O工艺,经检测发现其曝气池溶解氧浓度较低,不能满足处理要求.2008年2月对其曝气系统进行改造,改造后曝气池溶解氧较改造前有了较大提高,各污染物去除效率也有所改善.介绍了工程改造的具体内容,并对改造工程进行了经济效益分析.%The A/O process was employed in Sibao Wastewater Treatment Plant in Hangzhou City. The dissolved oxygen content was measured to be low, which could not satisfy the need of treatment. The reconstruction of its aeration system was carried out in February 2008. After the reconstruction, the dissolved oxygen content in aeration tank was increased greatly and the pollutants removal efficiency was also improved. The specific information of the reconstruction project was introduced and the economic analysis of the reconstruction project was also carried out.
