Description

technical field [0001] The invention relates to the technical field of sludge monitoring, in particular to an activated sludge online monitoring device. Background technique [0002] The activated sludge method is widely used in the sewage treatment process. Through the processes of suspension mixing, adsorption contact reaction, and flocculation precipitation, pollutants such as COD, TP, TN, and SS dissolved in water are removed, and finally discharged to the environment after reaching the urban sewage discharge standard. During the operation of sewage treatment plants, there are often unpredictable factors that lead to fluctuations in influent water quality, such as pollutant concentration changes, component changes, temperature changes, toxic substances intrusion, etc., which adversely affect the stable operation of activated sludge, and even system collapse. . Therefore, it is necessary to grasp and control the properties of activated sludge in time for process operatio...

Problems solved by technology

Its disadvantages are due to the limitations of current sensor detection technology. First, it can only directly detect part of the instantaneous data, but the research on the hysteresis of the biological reaction system is insufficient, the detection equipment is not perfect, and the data multi-factor comprehensive analysis ability is low; the second is the biological system. The physical and chemical characteristics of sludge such as dehydrogenase activity and ATP content detection are cumbersome or costly, and it is not easy to promote online

Therefore, the complexity of the intelligent operation of the bioreactor makes the system adjustment prone to vibration and repetition, and the implementation effect is not good.
