Abstract

A small immersion type test device was manufactured as a treatment device for insolubilizing harmful substances such as hexavalent chromium and fluorine in biomass incinerated ash. This device puts biomass incinerated ash into a treatment tank filled with treatment agents, and collects the treated ash from the bottom of the treatment tank. The insolubilization of chromium was confirmed using a ferrous sulfate (II) and acidic calcium hydrogen phosphate. Using this method, basic data for the continuous treatment of various incineration ashes was accumulated.
