Biological-activity monitoring device for monitoring abnormal operation of sewage disposal system and monitoring method thereof

Abstract

The invention discloses a biological-activity monitoring device for monitoring abnormal operation of a sewage disposal system and a monitoring method thereof; the biological-activity monitoring device is applied to monitoring the abnormal operation by combining a detecting method of microorganism physiology and biochemistry activity through a constructed biological-activity monitoring device for providing reference basis for corresponding restoration activities; the device and the method have the remarkable advantages that: (1) the detection of the microorganism physiology and biochemistry activity is simple, convenient and rapid; (2) the detection of the microorganism physiology and biochemistry activity is applied to the operating management of the sewage disposal system, mainly aiming at early warning of the abnormal operation, therefore, the method has the advantages of high sensitivity, good pragmaticality, and being capable of timely reflecting the abnormal operation and the like; (3) the method provides reference basis for corresponding restoration activities, the process controlling time is shortened, thus having positive significance for safe and stable operation of a sewage disposal plant.

Description

technical field [0001] The invention relates to the technical field of wastewater biological treatment, in particular to a biological activity monitoring device and a monitoring method for abnormal operation of a sewage treatment system. Background technique [0002] A / A / O process is a typical wastewater treatment process for denitrification and phosphorus removal, with mature technology and wide application. The most basic daily detection indicators include aeration tank DO (dissolved oxygen), SVI (sludge volume index) and effluent COD (chemical oxygen demand) (or BOD 5 , that is, five-day biochemical oxygen demand) and microscopic examination of microorganisms, etc., and use this as the basis for process control. For the traditional activated sludge process, it is unavoidable to be impacted by sudden changes in water quality and environmental conditions, and microbial phase abnormalities such as sludge bulking, disintegration, floating and biological foam often occur. If...
