Abstract
PURPOSE:To prevent generation of malodor in a stage of concentrating waste photographic processing liquid, etc., by heating with a heating means and condensing simultaneously evaporated component, by heating with a semiconductor heater comprising a semiconductor ceramic which emits far infrared rays. CONSTITUTION:In a stage of concentrating waste photographic processing liquid, etc., by heating with a heating means and condensing simultaneously evaporated component, the waste liquid is heated with a semiconductor heater utilizing a semiconductor ceramic 3 which emits far infrared rays. For example, the semiconductor heater comprises a U-shaped heater main body 1 made of a quartz tube, etc., houses an insulating ceramic body 2, and a semiconductor ceramic 3 emitting infrared rays enclosed by a coil shaped heating element 4 (e.g. 'Kanthal(R)') having high heat resistance is embedded in the bottom part of the main body 1 of the ceramic 2. The ceramic 3 comprises a sintered alloy comprising an oxidized metal, metal, silicon oxide, carbon, surface active agent, and ceramic. As a result, a remarkable malodor preventing effect is realized, and sticking of components to be discarded to the semiconductor heater is prevented.
