Background

A sludge tank in the MBR process technology comprises an anaerobic tank and an aerobic tank, wherein the oxygen concentration in the sludge tank is one of key control factors for guaranteeing the activity of aerobic and anaerobic microorganisms, the oxygen concentration of the anaerobic tank is generally controlled to be not more than 0.2mg/L, and the oxygen concentration of the aerobic tank is controlled to be 2-4 mg/L. For anaerobic microorganisms, if the oxygen concentration is too high, the metabolic rate of the anaerobic microorganisms and the amount of pollutants absorbed by the anaerobic microorganisms are directly affected. For aerobic microorganisms, if the oxygen concentration is too low, the metabolic rate of anaerobic microorganisms and the pollutant absorption amount of the aerobic microorganisms are directly influenced, and if the oxygen concentration is too high, a large number of oxygen molecules are remained, so that other mixed bacteria are bred. The proper oxygen concentration in the sludge tank is particularly important for the metabolic activities of aerobic microorganisms and anaerobic microorganisms. Therefore, the oxygen concentration index in the sludge tank needs to be monitored to guide the regulation and control of the oxygen concentration in the sludge tank.

At present, most of municipal sewage treatment plants usually operate in a mode that oxygen concentration detectors are directly hung on the inner wall of the periphery of a sludge tank or the oxygen concentration detectors are not directly installed.
