Abstract

The invention relates to a method of regenerating used oil by adopting antibiotic waste mushroom dreg biomass charcoal. The method comprises the following steps: 1) sterilizing and dehydrating antibiotic waste mushroom dregs to prepare waste mushroom dreg biomass charcoal or biomass active charcoal; 2) standing and layering the used oil, removing water at the lower layer and then filtering out solids and suspended solids to obtain the treated used oil; and 3) adding the used oil into the waste mushroom dreg biomass charcoal or biomass active charcoal, heating for reaction, and settling and carrying out suction filtering to obtain the regenerated oil. The method provided by the invention has the advantages that the biomass charcoal or biomass active charcoal prepared by antibiotic waste mushroom dregs has high specific surface area and good adsorptive property, solves the problem in disposal of waste mushroom dregs and realizes recycling of resources; a good decolorising agent is developed for the used oil, and the transmittance of the regenerated oil can reach 45-85%; recycle, reduction and harmless treatment of waste mushroom dregs and used oil are realized, so that the method has remarkable economical and social values.

Description

technical field [0001] The invention relates to a regeneration process of waste engine oil, in particular to a method for regenerating waste engine oil by using biomass charcoal of antibiotic waste bacteria residue. Background technique [0002] China is a major producer of antibiotics. According to the estimation that 1 ton of antibiotics produces about 10 tons of wet bacteria residues, China discharges about 1 million tons of antibiotic residues every year. It is conceivable that the amount is so large. In the past, the fungus residues have been dried and processed before being used as feed or feed additives. However, the produced organic fertilizers may contain residual antibiotics and metabolic intermediates, which are easy to accumulate and form drug resistance during the use of organic fertilizers, leading to potential ecological risks. . In 2008, the Ministry of Environmental Protection of the People's Republic of China has listed antibiotic waste bacteria residues ...
