Problems solved by technology

In addition, previous studies have shown that activated clay has a high oil absorption rate in the process of treating waste engine oil.
The amount of entrainment of engine oil is generally 20-50% of the amount of activated clay, which increases refining consumption and cost

Embodiment 1

[0022] 1) Sterilize the waste antibiotic residue at 121°C for 20 minutes to inactivate the mycelium;

[0023] 2) Dehydrate the antibiotic waste slag after the above-mentioned sterilization treatment at 8,000 rpm for 20 minutes in a centrifuge, and then put it into an oven to dry at 105-110°C for 4 hours;

[0024] 3) Carbonize the waste antibiotic residue after the above dehydration treatment at 750°C for 1 hour under the protection of nitrogen, pickle the obtained product with hydrochloric acid with a concentration of 4% by mass percentage, then wash with water until neutral, and dry at 105-110°C for 2 hours , cooled to room temperature, and the waste biochar was prepared. The attached figure is the electron micrograph of the prepared waste biochar. The figure shows that the waste antibiotic residue releases some gas and volatile Substances have formed many large, medium and small pore sizes, which are conducive to the adsorption of pollutants;

[0025] 4) After the waste eng...

Embodiment 2

[0028] 1) Sterilize the waste antibiotic residue at 121°C for 20 minutes to inactivate the mycelium;

[0029] 2) Dry the waste antibiotic residue after the above sterilization treatment in the air, and then dry it at 105-110°C for 4 hours;

[0030] 3) Carbonize the waste antibiotic residue after the above dehydration treatment at 300°C for 1 hour under the protection of nitrogen, activate it with steam at 500°C for 0.5 hour, pickle the obtained product with 10% hydrochloric acid by mass percentage, and then wash it with water to medium Drying at 105-110°C for 2 hours, cooling to room temperature, to obtain bio-activated carbon from waste fungus residue;

[0031] 4) After the waste engine oil is left to stand, it is separated into layers, the water in the lower layer is removed, and then the solids and suspended matter are filtered to obtain the treated waste engine oil;

[0032] 5) Heat the above treated waste engine oil to 60°C, and add waste bioactivated charcoal under cont...

Embodiment 3

[0034] 1) Sterilize the waste antibiotic residue at 121°C for 20 minutes to inactivate the mycelium;

[0035] 2) Dehydrate the antibiotic waste residue after the above sterilization treatment by plate and frame filter press, and then dry it at 105-110°C for 4 hours;

[0036] 3) Add the dehydrated antibiotic waste slag to 40% zinc chloride solution with a liquid-solid ratio of 1:1 (w / w), carbonize at 400°C for 0.5h under nitrogen protection, and then increase Activate at 600°C for 60 minutes, pickle the obtained product with sulfuric acid with a mass percentage concentration of 3%, then wash with water to neutrality, dry at 105-110°C for 2 hours, and cool to room temperature to obtain activated carbon from waste bacteria residue biomass;

[0037] 4) After the waste engine oil is left to stand, it is separated into layers, the water in the lower layer is removed, and then the solids and suspended matter are filtered to obtain the treated waste engine oil;

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 ...
