PROBLEM TO BE SOLVED: To dispense with setting of a filter to dispense with periodic replacement of a filter member or troublesome work such as cleaning, and to efficiently process waste liquid, in a processing device for radioactive washing wastewater processing the wastewater after cleaning and washing an object contaminated with radioactive substance, such as a body or clothes of a worker who worked in a radiation control area. SOLUTION: In this processing device, washing wastewater is sprinkled onto a surface of a rotating heated body 1 supplied with a heating medium 5 inside it by a sprinkler 10 to forcibly grow scale on the surface of the rotating heated body 1. Steam 6 evaporated on the surface of the rotating heated body 1 except the extracted scale is condensed into distilled water. The forcibly grown scale is scraped away from the surface of the rotating heated body 1 by a scraping member 2 and is collected. Thus, desired processing of the washing wastewater is executed. Accordingly, the processing of the radioactive washing wastewater is properly executed with a simple structure without the need to set a filter.
