Processing process of albiotic residue

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 ...

AI Technical Summary

Problems solved by technology

If the wet bacterial residue enters the sewage treatment system directly, it can also be fermented to produce biogas, but there will be endless troubles. Due to the accumulation of time, a large amount of residual bacterial residue will precipitate in the anaerobic facility, and the sludge particles will be replaced. Antibiotic residues inhibit microbial activities and COD removal rate Decrease, the amount of biogas production decreases, and the degradation load rate of anaerobic facilities decreases
