For fixing, the relation of its running current and time is straight line (as shown in Figure 6), and therefore application the present embodiment is for electrification
The running average power of the autocontrol method learning heavy metal-polluted water treatment system is less than far away application the present embodiment for electricity
The operation power 20KW to 62.5KW of former scheme before the autocontrol method of chemical heavy metal sewage disposal system such that it is able to arrive
Reach saves energy and extend the purpose of pole plate operation time.
Proving according to multiple electrochemical heavy metals sewage disposal system Projects, the time is the longest for the operation of pole plate fortune, disappear
Consume the fastest, then rectifier output voltage increases therewith.With according to this principle, in the present embodiment, step 2) also include according to commutator
Output voltage carries out the step of pole plate consumption detection, and its detailed step includes: detection electrochemical heavy metals sewage disposal system in real time
The output voltage of commutator in system, consumes extreme voltage values by output voltage and the pole plate preset and compares, if output electricity
Pressure consumes extreme voltage values more than or equal to the pole plate preset, then the commutator controlling electrochemical heavy metals sewage disposal system stops
Only export electric current, the most described output voltage is compared with the pole plate consumption alarm magnitude of voltage preset, if institute
State the pole plate consumption alarm magnitude of voltage that output voltage is more than or equal to preset, then alarm signal changed by output pole plate.By above-mentioned
Step so that (output voltage is more than or equal to the pole plate consumption alarm magnitude of voltage preset), electrochemistry weight when pole plate soon consumes
Metal sewage disposal system automatic control system alarm operator's change poles plate, and (output voltage when pole plate consumes the limit
Extreme voltage values is consumed more than or equal to the pole plate preset) it is automatically stopped commutator thus reaches to guarantee that electrochemical apparatus is transported safely
The mesh ground of row.In the present embodiment, the pole plate consumption alarm magnitude of voltage preset is by manually passing through human computer conversation's window at host computer
