Embodiment 1
[0039] 100 parts of lincomycin bacteria residue, 0.5 parts of EM stock solution, and 5 parts of alcoholic yeast culture solution.
[0040] 1. The alcoholic yeast culture solution is operated according to the formula and process of the first-class seed tank in the alcohol production of an alcohol factory, cultivated for 24 hours, and counted by microscopy. The number of yeasts per milliliter is more than 150 million, and it is set aside;
[0041] 2. Mix 0.5 parts of EM stock solution (qualified product purchased in the market) into 5 parts of alcoholic yeast culture solution and stir evenly;
[0042] 3. Pour the suspension in step 2 into 100 parts of bacteria residue and stir evenly at room temperature;
[0043] 4. Put it into a container for compaction, separate from oxygen, and cultivate for more than 96 hours;
[0044] 5. Take samples and send them to the laboratory to test for lincomycin residues;
[0045] 6. Make the fermented product into a 20% suspension with tap water...
Embodiment 2
[0051] Lincomycin residue 100 parts
[0052] 1 part of EM stock solution
[0053] 5 parts alcoholic yeast culture solution
[0054] Implementation method is the same as embodiment 1
[0055] The mellow aroma produced in this embodiment is concentrated, and the overall effect is better than that of Embodiment 1 (the amount of biogas produced does not increase significantly).
Embodiment 3
[0057] Lincomycin residue 100 parts
[0058] 0.5 parts of EM stock solution
[0059] 5 parts alcoholic yeast culture solution
[0060]The implementation method is the same as in Example 1, but the high-shear machine is used to select a high speed of more than 20,000 rpm, shear for 25 minutes, observe under a microscope, the hyphae are cut shorter, and the sample detection COD is more effective than 5700.

Abstract
The invention discloses a processing technology of the waste dregs of lincomycin. The technology comprises the steps that: the waste dregs of the lincomycin, the bacterial liquid of EM and the culture solution of alcohol yeast are mixed according to the proportion of 100: (0.5 to 1.5): (3 to 5) and stirred uniformly, and solid anaerobic fermentation is carried out for over 96 hours to remove antibiotics left in the waste dregs; the ferment material is diluted by water and prepared into 10 to 30 percent of a suspension which is uniformly stirred, and sheared and broken mechanically at high speed, reticular mycelium is cut into 'bacillus' shape by observation under a microscope, and by chemical detection: chemical oxygen demand (COD for short) is over 5000; a sheared solution is mixed with the high concentration organic wastewater of lincomycin by the proportion of 10 to 40: 100 put into a jar to carry out anaerobic fermentation and produce biogas. The method is practical, the gas production rate thereof is improved by over 30 percent, the indexes of an anaerobic system, such as the removal rate of COD, PH, degradation rate and sludge discharge, etc. are not affected, and facilities run normally.
Description
Technical field [0001] The invention belongs to the technical field of waste fungal residue treatment, and in particular relates to a treatment process for lincomycin waste fungal residue. Background technique [0002] The waste lincomycin residue has been included in the list of hazardous waste by the state. The main reason is antibiotic residues. In recent years, this type of fungal residue has been regarded as solid waste in antibiotic production. 3600-3800Kcal / Kg and mixed into coal as fuel for disposal. Dried lincomycin residues contain more than 38% protein, and more than 20,000 tons of dry residues are formed every year in the production of lincomycin nationwide. Combustion is a common method in domestic industry, resulting in a great waste of protein resources. [0003] For the high-concentration wastewater formed in the production of lincomycin, the domestic counterparts use anaerobic biogas to generate biogas, and then discharge it after aerobic, flocculation and ...
