在污水处理厂的实际运行管理中,影响活性污泥处理工艺运行效果的因素很多,在缺乏经验数据的情况下,运行管理人员常以污泥容积指数(SVI)作为指导运行的主要参数.通过对西安市第三污水处理厂Orbal氧化沟工艺在运行中的实测结果进行统计分析,归纳出了SVI与污泥负荷N_s、溶解氧DO及出水SS之间的相关关系,提出以SVI值指导Orbal氧化沟的工艺运行.

There are many factors influencing the operation efficiency of activated sludge treatment process in the actual operation and management of wastewater treatment plants.The sludge volume index (SVI)is often considered as one of the most important parameters in the absence of empirical data.The measured results of Orbal oxidation ditch process in Third WWTP of Xi'an City are analyzed.The relationships of SVI to sludge loading rate,DO and effluent SS are generalized.It is put forward that SVI value is used to guide the operation of Orbal oxidation ditch process.
