The electrode means that allows the above-mentioned three-phase alternating current power to act on the microorganisms is arranged by arranging a plurality of electrode means capable of energizing, rotating, and electromagneticizing the treatment system or the habitat. The treatment method is made to improve the function of decomposing the refractory organic matter of the microorganism by causing the microorganism to intervene with the action of the electrolytic iron generated from the energization, rotation, electromagnetic force, and electrolytic action.

The invention's effect

  As described above, the treatment method and apparatus of the present invention enables advanced treatment of wastewater containing persistent organic substances, thereby correcting the uneconomical nature of treatment methods using conventional microorganisms and building treatment facilities. About 50% of the cost can be reduced and about 30% of the processing facility operating cost can be saved.

Usually, when an aerobic microorganism is used, air aeration means for supplying dissolved oxygen to A is provided, and when an anaerobic microorganism is used, the outside air contact area of A is blocked and the generated fermentation gas (methane gas) is externally supplied. Can be separated and used as fuel.

R, S, and T represent a three-phase AC power source having a frequency of 30 Hz or more for energizing microorganisms, and R1, S1, and T1 respectively indicate electrode means for connecting and energizing each of the three-phase AC power sources to A. Each electrode means is subjected to insulation treatment other than A to be inserted and contacted, and is supported in a predetermined and necessary manner.
R2, S2, and T2 represent each of the three-phase alternating currents supplied from the electrode means provided and supplied to the A microorganism.
R3, S3, and T3 represent rotating means of the electrode means for rotating each of the electrode means, and rotate the insertion contact surface with A. The number of rotations may be such that a scale ring prevention or suppression effect on the electrode means insertion contact surface is obtained.

In the case of using an iron-based material, maintenance and workability can be improved by taking measures for replacing and detaching electrode means in consideration of electrolytic dissolution and electrolytic corrosion.

  U represents an ultrasonic wave generating means for supplying an ultrasonic wave to A and causing it to act. The installation mode aims to continuously supply ultrasonic waves to A.

  R5, S5, and T5 represent three-phase AC power half-wave rectifying means that interpose the electrode means R1, S1, and T1, respectively, and each electrode means and three-phase AC power half-wave rectifying means R6, S6, and T6.
