摘　　要：为降低甾体药物菌渣的环境污染风险、减少资源浪费,实现9-羟基雄烯二酮(9α-OH-AD)药物菌渣无害化与资源化,本研究确立了9α-OH-AD菌渣好氧堆肥处理体系,讨论初始碳氮比分别为15(低)、20(中)、25(高)的堆体在堆肥过程中的特征变化,并通过土壤模拟实验评估其作为肥料的可行性和安全性。研究结果表明:优化后的好氧堆肥工艺可以实现9α-OH-AD菌渣的有效降解及稳定,所得菌渣肥的理化指标均满足有机肥标准,且部分指标优于商品肥标准。施入1%菌渣肥一段时间后,土壤和蚯蚓中未检出9α-OH-AD残留,蚯蚓雌雄生殖系统无明显变化,同时施肥土壤的酶活性和微生物多样性都有所提高。研究表明,9α-OH-AD菌渣可以通过好氧堆肥有效转化为稳定无害的肥料,并实现资源回收与土地安全利用。This study sought to reduce the risk of environmental pollution and resource waste of steroidal fermentation residue,and realize the safe utilization of 9-hydroxy-4-androstene-3,17-dione(9α-OH-AD)fermentation residue.An aerobic composting treatment system for 9α-OH-AD fermentation residue was established.Changes of the characteristics of the piles with the initial carbon to nitrogen ratios of 15(low),20(medium),and 25(high)were determined during the composting process.Finally,the feasibility and safety of 9α-OH-AD fermentation residue as a fertilizer was explored in soil simulation experiments.The optimized aerobic composting process permitted effective degradation and stabilization of 9α-OH-AD fermentation residue.The physicochemical indices of the resulting fermentation residue fertilizer all met the organic fertilizer standard,and some indices were better than commercial fertilizer.After a period of time,no residues of 9α-OH-AD were detected in the soil and earthworms fertilized with 1%rate of fermentation residue fertilizer.No significant changes were evident in reproductive systems of male and female earthworms.The enzymatic activity and microbial diversity of the fertilized soil were increased.The study shows that 9α-OH-AD fermentation residue can be effectively transformed into a stable and harmless fertilizer by aerobic composting,allowing resource recovery and safe land utilization.
