超電導磁気分離と亜臨界水熱分解による廃水処理システムの検討

抄録

We studied a treatment method on beavy metal separation and sludge decomposition using a superconducting magnetic separation and a hydrothermal decomposition method. The experiment showed that the superconducting magnetic separation method to which a high gradient magnetic filter was applied proved to be practically used to remove 90% of heavy metal particles and that the hydrothermal decomposition method proved effective in dehydrating sludge and in minimizing the volume. The study also showed a well-posed hydrothermal condition on temperature and oxidation that matched the magnetic separation to remove heavy metal in sludge.
