Abstract
The invention discloses an intelligent aeration system with a dissolved oxygen meter. The intelligent aeration system comprises the dissolved oxygen meter, an aeration disc, a PLC (programmable logic controller), a frequency converter, an aeration tank and a blower. Intelligent control of dissolved oxygen in the aeration tank is achieved by putting a detection probe of the dissolved oxygen meter in the aeration tank, sending parameter signals of the dissolved oxygen in the aeration tank into the dissolved oxygen meter, transmitting data to a data processing module of the PLC by the dissolved oxygen meter to calculate the biological oxygen demand and dissolved oxygen of the aeration tank, sending an instruction to a blower regulating module in the frequency converter after comparing the calculation results with the programs preset in the PLC, regulating the blast volume of the blower to control appropriate biological oxygen demand in the aeration tank and simultaneously sending an instruction to an air flow distribution module in the frequency converter to regulate an electric flow regulating valve of an aeration pipeline in the blower.
