PURPOSE: A space control device of a waste water treatment apparatus is provided to improve the efficiency of the electrolysis by moving an electrode in a convenient way by maintaining a constant interval according to the electrolyte even in a state that multiple electrodes are equipped. CONSTITUTION: A space control device of the waste water treatment apparatus comprises a flocculation basin(110); multiple electrodes(121,122,123) formed within the flocculation basin; a rotary shaft(131) crossing the flocculation basin; and the electrode connecting part. The rotary shaft comprises the first screw thread part(131a) with the first pitch and the second screw thread part(131c) with the first pitch with the opposite formation direction. The electrode connecting part comprises the first electrode connecting part(132a) where one of the electrodes is combined moving along with the first screw thread part while being combined with the first screw thread part and the second electrode connecting part(132b) where one of the electrodes is combined moving along with the second screw thread being combined with the second screw thread part. The rotary shaft also includes the third screw thread part with the second pitch being formed outside of the first screw thread part and the fourth screw thread part with the second pitch being formed outside of the first screw thread part in an opposite formation direction of the third screw thread part. The electrode connecting part can further include the third electrode connecting part in which one of the electrodes is combined moving along with the third screw thread part while being combined with the third screw thread part and the fourth electrode connecting part in which one of the electrodes is combined moving along with the fourth screw thread part while being combined with the fourth screw thread part. The second pitch is the two times of the first pitch. |
