| titleOfInvention | A kind of arsenic sulfide slag wet mineralization and detoxification treatment method |
| abstract | The invention discloses a wet mineralization and detoxification treatment method for arsenic sulfide slag, comprising the following steps: adding arsenic sulfide slag into water to obtain arsenic-containing slurry, adding a composite oxidant under stirring, reacting for the first time, and then continuing to stir A mineralizer is added to the bottom, and the second reaction is performed, and the detoxification slag obtained after the reaction is maintained to obtain a mineralized slag. The invention utilizes the composite oxidant to effectively convert the arsenic in the arsenic sulfide slag into a high valence state, and then reacts with the mineralizer to generate arsenic-containing minerals with low solubility product, and through the strong coordination adsorption, the free arsenic sulfide slag is converted into the arsenic sulfide slag. , Arsenic in the non-specific adsorption form is converted into a complex mineral form that can exist stably for a long time, so as to achieve efficient detoxification of arsenic sulfide residue. The method is simple in process, short in cycle, stable in effect, small in volume expansion ratio, and low in treatment cost. After the arsenic sulfide slag is mineralized and detoxified, all indicators can reach the limit value in the "Hazardous Waste Landfill Pollution Control Standard", which can be Dispose of in a safe landfill. |
