Environmental-protection treatment technology of mineral oil waste

The invention discloses a mineral oil waste treatment process: (1) processing of chemical agents: heating to 400 DEG C with a demulsifier, polyacrylamide, cassava acetylated distarch adipate starch and sodium silicate to dissolve and react for 1 h so as to form a transparent liquid, and barreling for later use; (2) putting mineral oil waste into a heating tank, adding a medicament according to the ratio of 1 ton of the mineral oil waste to 0.5% of the medicament, heating to about 80 DEG C and fully stirring, demulsifying and decomposing the mineral oil waste, precipitating for 2 h, extracting crude oil, extruding wastewater and impurities by a filter press, filtering out moisture, and forming powdery solids from the impurities. Oil and impurities processed by the technology are all tested through a professional testing agency and all reach the discharge standard of national requirements.
