Degradation and harmless treatment method for residual antibiotics in livestock excrement

Abstract

The invention discloses a degradation and harmless treatment method for residual antibiotics in livestock excrement. The method comprises the following processing steps that 1, the livestock excrement enters a mixer after being preheated; 2, quicklime is put in the mixer and stirred; 3, the mixture is input into a degradation kettle, stirred and heated; 4, gas is sucked through a vacuum system when the mixture is heated; 5, gas-liquid separation is performed after the sucked gas is cooled, gas is exhausted after being irradiated through ultraviolet light and washed through a washing tower, and liquid is drained after being treated through ozone, filtered and precipitated; 6, bleaching powder saturated solutions accounting for 3%-5% of the total mass of the materials are sprayed into the degradation kettle and stirred; 7, the materials are discharged, solid-liquid separation is performed after the materials are cooled, solids are stacked for decomposition, and liquid is treated through anaerobic fermentation. The degradation and harmless treatment method for the residual antibiotics in the livestock excrement is convenient to operate, high in mechanization degree, large in treatment capacity, efficient, rapid, capable of effectively degrading and harmlessly treating the residual antibiotics in the livestock excrement and suitable for industrialization production, and meanwhile sterilization and disinfection for the livestock excrement also can be completed; after the livestock excrement is treated through the technologies, and the effects of achieving complete degradation of the residual antibiotics and being free of residues harmful to various organisms in a natural environment can be achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for degrading and harmlessly treating residual antibiotics in excrement of livestock and poultry. Background technique [0002] With the rapid development of my country's livestock and poultry breeding industry, the total amount of livestock and poultry excrement is also increasing. In the process of livestock and poultry breeding, in order to improve the survival rate and slaughter rate, improve economic benefits, and reduce the spread and death of livestock and poultry diseases, various types of antibiotics are widely used in feed to raise livestock and poultry. Antibiotics are drugs commonly used to treat a variety of non-viral infections. It can not only kill bacteria, but also has a good inhibitory and killing effect on other pathogenic microorganisms such as mold, mycoplasma, chlamydia, spirochetes, and rickettsia. It can be directly ...

AI Technical Summary

Problems solved by technology

However, due to various reasons, there is a widespread phenomenon of excessive and excessive use of antibiotics, resulting in a large amount of animal antibiotics that inevitably remain in excrement of livestock and poultry.

These residual antibiotics are directly discharged into the environment without harmless treatment, which will seriously affect the ecological environment, lead to the emergence of various drug-resistant organisms and superbugs, and cause harm to humans and the ecological environment
