摘要

摘要: 采用中温中压氧化干化(MOD)技术对头孢菌渣、青霉素菌渣进行无害化处理,处理后菌渣(菌渣肥)中抗生素残留低于检出限(1 mg/kg)。经过对菌渣肥调质后,有机物、氮磷钾营养成分、重金属浓度等指标均可满足NY 525—2012《有机肥料》的要求,菌渣肥中7种典型耐药基因均未检出。进一步施肥试验结果表明:菌渣肥按1%和3%施入土壤30 d后,土壤中均未检出抗生素残留;菌渣肥能降低土壤的耐药基因富集程度。

Abstract: Moderate oxidation drying(MOD)technology was used to treat cephalosporin and penicillin residue harmlessly, and after treatment the antibiotic residues in the samples were below the detection limit(1 mg/kg). After adjusting and treating the residue fertilizer, the targets of organic matter and nitrogen, phosphorus and potassium nutrients and the content of heavy metals all met the requirements of Organic Fertilizer Standard(NY 525-2012), and none of seven kinds of typical drug-resistant genes in antibiotic residues was detected. The further fertilization tests showed that the antibiotic residues after MOD treatment were applied to the soil at 1% and 3%, and no antibiotic residue was detected in the soil after 30 days. The treated residues could reduce the accumulation of drug-resistance genes after application to the soil.
