摘要： It is an objective of the present invention to provide a decontaminant capable of efficiently and rapidly decontaminating soil, groundwater or sediment contaminated with hexavalent chromium, and a decontamination method utilizing the same. By adding at least one of iron (0) and ferrous iron, and a microbial biostimulant of at least one member selected from the group consisting of yeast extract, inactive yeast, active yeast and peptone to soil, groundwater or sediment contaminated with hexavalent chromium. Hexavalent chromium is chemically and biologically reduced efficiently, and iron reducing microorganisms are propagated and activated to sustain reducing power of the added iron over a long period of time.

摘要： According to one embodiment, a solid removal process in a filter and a positive metal ion removal process in a positive metal ion-exchange resin column are performed sequentially through an etching acid waste liquid disposal circulation flow channel, the solid removal process is performed on an upstream side of the positive metal ion removal process, furthermore after the positive metal ion removal process, a negative metal ion removal process removing at least B using a chelate forming fiber or a chelate forming resin is performed on a downstream side of the etching acid waste liquid disposal circulation flow channel, thereby an etching acid waste liquid is recycled sequentially through the etching acid waste liquid disposal circulation flow channel.
