example 1

[0023] First, mix 5-6 tons of antibiotic residues to be treated with trypsin and phospholipase C in a mass ratio of 100:1:1, and keep warm for 7-10 hours at 35-37°C for enzymolysis. Spray the frozen enzymatic hydrolyzate with liquid nitrogen for 3 to 5 minutes, then put the frozen enzymatic hydrolyzate into a grinder and pulverize for 20 to 30 minutes to obtain a mixed pulverized product, and dig a 3m long, 2m wide, and deep For a 2m biogas digester, use cement to paint the bottom and wall of the pond evenly, and then lay a layer of polyethylene geomembrane on the bottom of the pond. Insulate and ferment at ~45°C for 5-7 days, collect the biogas produced during the fermentation process, and after the fermentation is completed, scoop out the fermentation product and filter, separate the filter residue and filtrate, and use the filtrate for later use, weigh 1-2kg of filter residue and 2-4L to remove Mix ionic water to obtain a mixed solution, then put the mixed solution into a h...

Abstract

The invention discloses a method for harmless resourceful treatment of antibiotic mushroom dregs, and belongs to the technical field of solid waste treatment. Firstly, a mushroom dreg cell thin film structure is destroyed through composite enzymatic hydrolysis and is initially fractured; then liquid nitrogen frozen is carried out to enable water in cells to freeze and swell instantly, the cells are supported to be broken, bound water in the mushroom dregs and the water in the cells are released and desorbed, the mushroom dregs obtained after dehydration are subject to anaerobic fermentation, marsh gas obtained after fermentation is collected to provide pyrolysis energy sources, the mushroom dregs obtained after fermentation are subject to pyrolysis coking through a hydrothermal method, and porous coking objects are obtained; and carbonization and excitation are carried out to prepare activated carbon, hydro-thermal treatment liquid is subject to distilling to removal water, then biological fuel oil is prepared, and harmless resourceful treatment of the antibiotic mushroom dregs can be carried out. According to the treatment method, needed energy consumption is low, the treatment period is short, resource reutilization is achieved, antibiotic residues and secondary pollution are avoided, and the wide application prospect is achieved.

Description

technical field [0001] The invention discloses a method for harmless resource treatment of antibiotic bacteria slag, belonging to the technical field of solid waste treatment. Background technique [0002] Antibiotic mycelium waste residue is the waste in the process of antibiotic production by enterprises. The main components of fungal residue are mycelium, unused medium (such as soybean meal, corn steep liquor, peanut cake powder, glucose, etc.), fermentation process Metabolites produced, degradation products of the medium, flocculants, acidifiers, filter aids, residual organic solvents, residual antibiotics and metabolic intermediates added during the extraction process. [0003] At present, the treatment of antibiotic residues mainly includes incineration, feed, energy, fertilizer and so on. Incineration is the process of oxidizing and burning antibiotic residues to form organic matter or carbon dioxide. Although it can realize the harmless treatment of waste, it requir...
