摘要
通过对吉林省延吉市污水处理厂A2/O法污水处理工艺一年来的运行情况进行分析研究,针对城市所处的地理环境冬季严寒漫长、夏季温热多雨的特点,分析总结工艺的运行情况,对其处理效果随季节变化规律进行初步分析研究,并对工艺运行过程中所存在的问题进行分析提出改进方案.
The traditional activated sludge process, one of widely used biological wastewater treatment technology, should be improved due to its deficiencies in purification. Anoxic-Anaerobic-Aerobi process（A^2/O） is one of the measures to improve purification capacity of the traditional activated sludge process. The same treatment of sewage process may arise different issues in the actual process of running when the local environment,cli-mate conditions and other factors are different. Based on the research and analysis on the A^2/O process running in YanJi City of Jilin Province in the past year, this article analyzes the treatment effect varying with season with the characteristics of the long cold winter and rainy hot summer in the city, and analyzes the problems existing in the process and presents the countermeasures.
