活性污泥法的工艺参数控制(上)

活性污泥法的工艺控制是通过各工艺参数的控制来实现的,有些运行参数的控制要求还因污水处理要求和运行模式而异.只有正确理解各运行参数的涵义,了解不同工艺及相同工艺下不同运行模式的控制要求,才能通过科学管理控制好工艺运行状态,使处理系统高效低耗地运行.主要介绍了活性污泥法的工艺运行参数在实际应用中的理解和控制方法,阐述了一些书面定义和观点与实际应用时情况不相符的原因,提出了各控制参数与其他因素的关系及相关方面的一些综合分析思路,以期对运行管理有一定的参考作用.

Control of technological parameters in activated sludge process(Ⅰ)

The activated sludge process(ASP)in working has to be controlled by operating pa- rameters,some of which are particular for special operating modes and treatment targets.Correct knowledge on the parameters for special processes and the control mechanisms of them are impor- tant for scientific management of the process operation,to get a high effective and low expense per- formance.In this paper the significance and function of main control parameters for ASP are pre- sented and some misconceives causing differences between written definition and practical applica- tion are expatiated,also considerations for comprehensive analysis of control parameters and other related factors are proposed,all of which could be helpful for operation management of ASP.
