Abstract :
In order to ensure the sewage treatment equipment operation cycle and the suction pump intermittent work and realize automatic SBMBR sewage treatment equipment intelligently, this paper selected MITSUBISHI FX2N series PLC to introduce SBMBR sewage treatment system for control system. By analyzing of automatic control system targets, program design process is given. Eventually, designed automatic control system achieves automatically water stirring, water and control of anaerobic, anoxic, aerobic time. Automatic control system provides a reliable guarantee for the normal operation and effluent quality of SBMBR. The commissioning and operation practice has proved that system greatly improved the degree of automation and achieved good impact.
