摘　　要：为了对土霉素菌渣进行减量化处理,采用微波-碱联合作用的方法,通过正交试验和单因素试验,考察了NaOH投加量、微波功率和含水率对悬浮固体(SS)去除率的影响。试验结果表明,最佳反应条件为NaOH投加量0.09g/g(质量分数),微波功率700 W和含水率96%,这时SS去除率达56%以上。通过扫描电镜对溶胞效果进行分析可知,该研究的土霉素菌渣减量化效果较好,可为抗生素菌渣减量化提供技术参考。For the minimization of terramycin bacterial residue,microwave-alkaline pretreatment is used.By measuring the changes of suspended solids and pH in the reaction system,the effect of different dosage of NaOH,microwave power and initial moisture on the minimization of the terramycin bacterial residue is investigated.Orthogonal experiment and single fact experiment are applied to determine the optimal reaction conditions.The results show that the best operating conditions are the dosage of NaOH is 0.09g/g,microwave power is 700 Wand the initial moisture is 96%.Under these conditions the removal rate of SS is more than 56%.In addition,the effect of the solution is analyzed by scanning electron microscopy.This study achieves ideal minimization results of terramycin residue,which provide technical reference for antibiotics residue minimization.
