Abstract: The present disclosure provides a solid waste treatment method, including following steps: screening off masses having a particle size greater than 0.5 cm from solid waste; adding extraction agents to the solid waste and then heating and stirring so that the solid waste is fully dispersed in the extraction agents; placing the mixed extraction agent in a centrifuge and centrifuging the mixed extraction feeding liquid phase separated by centrifuging into a rectification tower for rectification and cooling, recovering residual oil substances in a rectification kettle, separating mixture of cooled extraction agents and water, continuously adding the separated extraction agents into an extraction kettle for cyclic extraction, and conveying sewage to a sewage treatment plant to treat and discharging the sewage after the sewage reaches a treatment standard.
