Title:
RADIATION CONTAMINATION WASTEWATER TREATMENT METHOD, TREATMENT SYSTEM AND MOBILE PROCESSOR
Document Type and Number:
Japanese Patent JP2013088278
Kind Code:
A
Abstract:

To provide a radiation contamination wastewater treatment method and treatment system capable of quickly, simply and inexpensively performing adsorption treatment of radioactive material in wastewater containing the radioactive material and performing volume reduction of the treated radioactive material, and a mobile processor.

Radioactive material is subjected to adsorption treatment by adding powder zeolite for agitation after adding powder active carbon to raw water composed of wastewater containing radioactive material for agitation, or simultaneously adding the powder active carbon and a powder adsorbent for adsorbing radioactive material for agitation. Next, after forming flocculated flocks by adding and agitating an inorganic powder flocculating agent made chiefly of active silicon dioxide and alumina, the flocculated flocks are deposited due to still standing, the deposited flocculated flocks are dewatered and filtered, and the sludge thereof is stored in a storage vessel having a radioactivity screen effect.
