In integrated sewage equipment, the supply and control of oxidizing gas are important for the effect of sewage treatment. It helps maintain the growth and metabolic activities of microorganisms during the biochemical process. The following are some common methods for controlling the amount of oxidizing gas in equipment:

       1Gas flow meter control: Install a gas flow meter to monitor and control the supply of oxidizing gas. According to the processing capacity of the equipment and the water quality, the appropriate gas flow rate is set to ensure that microorganisms undergo biochemical degradation under appropriate conditions.

       2Dissolved oxygen concentration control: Install a dissolved oxygen sensor in the biochemical reaction tank to adjust the supply of oxidizing gas by monitoring the dissolved oxygen concentration in the reaction tank in real time.Integrated sewage equipmentControl the gas supply according to the set dissolved oxygen concentration range to avoid excessive or insufficient gas supply.

       3, Oxidation-reduction potential control: Use oxidation-reduction potential to monitor the metabolic state of microorganisms in the reaction tank, thereby adjusting the supply of oxidizing gas. According to changes in redox potential, the gas supply is adjusted in real time to maintain a suitable microbial growth environment.

       4Feedback control: The feedback control system is used to automatically adjust the supply of oxidizing gas according to changes in sewage quality and treatment effects. For example, the gas supply is adjusted according to changes inCOD, ammonia nitrogen and other indicators to achieve good treatment effects.

       5, Timing control: Set the timing air supply mode according to the working mode and processing requirements of the equipment. According to different time periods and workloads, the supply of oxidizing gas is controlled to meet the processing requirements under different circumstances.

       In actual operation, the appropriate oxidizing gas volume control method should be selected based on the water quality characteristics of sewage, treatment requirements, and equipment design parameters. At the same time, control parameters are regularly monitored and adjusted to ensure stable and excellent processing effects of Integrated sewage equipment.
