Abstract
PURPOSE: To reactivate the adsorptive filter media used in various kinds of industrial waste liquid treatments and sea water desalting treatments electrically without removing the same from the treating system by applying the pulse voltages generated during electrode switching of cathode and anode.
CONSTITUTION: Pulse voltages are generated at every constant time in the positive and negative electrode chambers of activated carbon filter tanks 1W3; at the same time, the positive pole is converted to the negative pole and the negative pole to the positive pole. At the same time, the raw water which is subjected to neutralization and flocculating and settling of foreign matter from an inverted funnel-shaped treating chamber 5 is passed through the tanks 1W3 and a flocculating and filtration tank 4. During this time, the switching time for the pulse generation and the conversion to positive and negative of the tanks 1W3 is determined in accordance with the turbidity, COD, BOD, dissolved matter, etc. of the raw water. For example, it is possible to cause self-activation of activated carbon by applying pulse voltage t1=120sec, constant voltage T2=20sec in the output waveform like that in figure A in the raw water treatment of respectively constant amts. and performing switching of positive and negative at every 30sec in the case of the waste water of food treatments.
