改良A^2/O工艺在南方雨季的工艺运行控制

Operation and Control of Improved A^2/O Process Used in Rainy Seasons of Southern Cities

介绍了南方雨季时某城市污水处理厂采取的措施,即通过对改良A^2/O工艺进行适当的工艺调整,使污水处理厂在雨季进水有机物含量较低,而TP偏高、泥砂含量较多、DO也偏高的情况下保证处理效果,并降低污水厂工艺设备遭受严重磨损的风险。

The paper introduces the process adjustment measures adopted in a southern urban sewage treatment plant in rainy seasons. That is under the low influent organic concentration, high TP concentration, high grit sand concentration and high DO concentraton, the treatment efficiency can be ensured and the risk of abrasion equipments of the sewage treatment plant is decreased through a proper adjustment of the improved A^2/O process.
