An aerobic composting method for efficiently degrading sulfonamide antibiotics in livestock and poultry manure

Abstract

The invention provides an aerobic composting method for efficiently degrading sulfonamide antibiotics in excrements of livestock and poultry. According to the method, the excrements of the livestock and poultry are mixed with conditioners such as straws, sawdust and the like, so that the carbon nitrogen ratio is optimized as 20 to 30; and the moisture content is optimized as 60% to 70%. Thus, the sulfonamide antibiotics remaining in the excrements and the urines of the livestock and poultry are effectively degraded. Therefore, the problem of the sulfonamide antibiotics which can pollute the environment and are harmful to human health is solved. As a result, the guarantee for large-scale breeding as well as harmlessness, reclamation and industrialization of the excrements of the livestock and poultry in the future is provided.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and environmental protection breeding, and in particular relates to an aerobic composting method for efficiently degrading sulfonamide antibiotics in livestock manure. Background technique [0002] The traditional control of pollutants from livestock and poultry farming is mainly reflected in the control of a large amount of nitrogen, phosphorus, mineral elements and the odorous gases such as ammonia and hydrogen sulfide in livestock and poultry manure. However, in recent years, with the rapid development of my country's aquaculture industry, in order to reduce the morbidity and mortality of livestock and poultry, aquaculture factories have widely used antibiotic veterinary drugs in large quantities. Studies have shown that veterinary drug antibiotics cannot be completely absorbed by the stomach of animals, and about 30-90% are excreted with animal feces in the form of parent compounds. ...
