Description

technical field [0001] The invention belongs to the technical field of aluminum phosphide residue treatment, and in particular provides a non-toxic and harmless treatment agent for aluminum phosphide residue and a treatment method thereof, which can effectively treat harmful substances in the aluminum phosphide residue. Background technique [0002] Aluminum phosphide is a widely used high-efficiency insecticide raw material at present. Its principle of action is to slowly mix aluminum phosphide with water at a certain temperature in a sealed high-pressure container, and the aluminum phosphide hydrolyzes to release phosphine and release The phosphine produced is diluted with carbon dioxide gas to prepare a certain concentration of phosphine gas, and then the certain concentration of phosphine gas is introduced into the warehouse where the goods are stored and fumigated to achieve the purpose of killing insects. Because phosphine has a strong insecticidal effect and has littl...
