PURPOSE: An apparatus for preventing dew condensation of the power supply part of a thickener pond for water treatment is provided to improve operating ratio of a water treatment facility and prevent water pollution by preventing dew condensation and permeation of corrosive gases caused by inner and outer temperature difference. CONSTITUTION: In a thickener pond which separates dust removing water flown in through an inflow watercourse(4) and a vertical channel(4a) into sludge and supernatant liquid, and on which a power supply part(10) is arranged, the apparatus for preventing dew condensation of the power supply part of the thickener pond for water treatment comprises a cover part which is equipped with a dually split outer cover(22) for encircling an inner cover(21) enveloping the vertical channel(4a), and in which the power supply part(10) is received in an internal space formed by a dually split upper cover(23) sealing the upper part of the inner and outer covers(21,22); a hydraulic turbine part which is equipped with a hydraulic turbine(32) that is rotated by a flow of the dust removing water of the inflow watercourse(4) and an exhaust fan(32b) that is rotated in a direction by rotary power of the hydraulic turbine(32) and installed inside an exhaust hood(33) of the upper cover(23) so that an external air is sucked in through a suction hood of the outer cover(22) in an amount as much as the air volume that is exhausted into the outside through the exhaust fan(32b); and a control part which is equipped with inner and outer part temperature sensors(41,42) for detecting an internal temperature of the internal space and the atmospheric temperature, and which judges whether to operate an alarm or not based on deviation temperature values of a temperature comparison controller(43) comparing detected temperature values of the temperature sensors(41,42).
