The workflow of the above-mentioned water quality advanced processing control apparatus of carbon filter based on the dynamic PID regulation technology comprises following step:
1) the sub-PLC that respectively filters lattice in the filter tank regulates the purge valve aperture automatically, carries out filter lattice constant water level filtering, and is as shown in Figure 2, and the concrete steps of filter lattice constant water level filtering are following:
11) water level gauge and pressure difference transmitter transmit filter lattice water level and purge valve aperture signal to the sub-PLC of each filter lattice;
12) sub-PLC calculates the water level that receives and the deviation between designated water level, and through after the pid control circuit computing among the sub-PLC, sends the output Attached Processor among the sub-PLC to exporting signal;
13) the output Attached Processor is exported to purge valve after the output signal is handled, and regulates the purge valve aperture, carries out filter lattice constant water level filtering.
2) main PLC detects the filtration time of respectively filtering lattice automatically; Automatically write down backwashing period; Judge whether the back flushing condition is set up; If condition is set up, then specify corresponding filter lattice to get into backwash process, the back flushing condition is set up and is meant that filtration time surpasses 24 hours or main PLC receives mandatory requirement back flushing order;
3) respectively filter grid PLC and report real time execution operating mode separately, and accept the back flushing instruction that main PLC assigns, and under the coordination of main PLC, accomplish the control of filter lattice backwash process to main PLC;
4) respectively filter grid PLC corresponding water intaking valve, purge valve, water are carried out failure testing, fault alarm and fault protection towards valve, gas towards controlled plants such as valve, wash water valve and vent valves;
