Problems solved by technology

This method can retain the organic nutrients in the fungus residue, but it is difficult to meet the requirements of harmless treatment, and it is difficult to ensure the degradation efficiency. This system is difficult to popularize and apply in industrial production.
[0008] In summary, the existing antibiotic residue treatment methods still have the technical problems of being difficult to guarantee the treatment results, prone to produce harmful substances, poor in safety and difficult to put into production and application.

Embodiment 1

[0092] use figure 1 The system integrates the treatment of antibiotics in penicillin residues. The residues contain high levels of antibiotics, the overall carbon-nitrogen ratio is low, and the water content is high, which is harmful to a certain extent.

[0093] Step 1: The moisture content of the original fungus residue is 80%, the carbon-to-nitrogen ratio is 4.7, and the antibiotic residue is 2000 mg / kg (dry weight). In order to meet the follow-up process, the water content needs to be reduced to below 65%, and the carbon-nitrogen ratio should be increased to between 25 / 1 and 35 / 1. Straw is used as the additional carbon source, and the carbon-to-nitrogen ratio is about 70 / 1. After calculation, 0.6 kg of straw should be mixed with every kg of fungus residue to meet the requirements of carbon-nitrogen ratio and moisture content. Add the penicillin residue to the mixing and feeding device, and mix it with the straw under the drive of the motor in the conveying area I, and the...

Abstract

The invention relates to the technical field of harmless and resourceful treatment of antibiotic mushroom dregs, in particular to an aerobic biological treatment and inactivation granulation synergistic system for antibiotic mushroom dregs. The system comprises a mixing and feeding device, a biological fermentation module and an inactivation and granulation module. On the basis of the prior art, the invention provides an aerobic biological treatment and inactivation granulation system for antibiotic mushroom dregs. Materials are premixed through the mixing and feeding device, and mushroom dregs are subjected to aerobic fermentation treatment through the biological fermentation device so as to reduce antibiotic residues. The inactivation and granulation module is connected behind the biological fermentation module, and inactivation and granulation treatment is carried out on the materials subjected to biological fermentation, so that pollutants in the fermented materials are further degraded, and the toxicity and pollution of products are reduced to the minimum to the maximum extent. According to the system, low-cost harmless and resourceful treatment of the antibiotic mushroom dregs can be realized.

Description

technical field [0001] The invention relates to the technical field of harmless and resourceful treatment of antibiotic scum, in particular to an aerobic biological treatment and inactivation granulation cooperative system of antibiotic slag. Background technique [0002] According to the "National Hazardous Waste List" revised in 2008, antibiotic residues are included in the category of hazardous waste. If it is directly incinerated and landfilled, not only the processing cost is high, but also a great waste of resources will be caused. The recovery rate of penicillin production is generally about 70%, and the remaining 30% remains in the fungus residue. The existing technological conditions have technical problems such as harsh extraction conditions, high extraction costs, low yield, and secondary pollution, which have great impact on the pharmaceutical industry. Continuous development has formed a technical bottleneck. [0003] Technologies for harmless treatment and re...
