摘　　要：文章以头孢菌素C菌渣为研究对象,在对其基本理化特性分析的基础上,通过检测厌氧发酵液中氨氮含量、产气量、p H值、抗生素残留等指标,评价中温（37℃±1℃）条件下不同料液浓度头孢菌素菌渣的可生化性及无害化问题,为头孢菌素菌渣的有效处置提供技术支持。结果表明,TS≥3.0%时,系统中VFA含量过高,p H值过低,发生酸抑制现象,发酵没有启动成功。TS为1.5%~2.5%时,随着有机负荷增大,沼气累积产气量增加,甲烷含量与常规原料相一致。当TS为2.0%,菌渣VS去除率为48.0%,产率达319.8 m L·g-1TS;当TS为2.5%,菌渣VS去除率为42.4%,产率达263.1 m L·g-1TS;发酵后沼渣中没有检测到抗生素残留,说明通过中温厌氧消化处理的方法无害化、能源化处理抗生素菌渣是完全可行的。Biodagradability and harmlessness of cephalosporin C bacterial residue under mesophilic anaerobic fermentation（ 37℃ ± 1℃） with different fermentation concentration were evaluated by detecting the contents of ammonia nitrogen,gas content,p H,and antibiotic residues. The results showed that the excessive amounts of VFA and too low of p H occurred in the anaerobic system when the TS concentration was greater than 3. 0%,which caused the failure of fermentation startingup. When TS 1. 5% ~ 2. 5%,and with the increasing of organic loading,the accumulation biogas production increased,in which the methane content was consistent with the conventional feeding materials. When TS was 2. 0%,the VS removal rate of cephalosporins bacterial residue was 48. 0%,and the gas yield was 319. 8 m L·g- 1TS. When TS was 2. 5%,the VS removal rate of cephalosporins bacterial residue was 42. 4%,and the gas yield was 263. 1 m L·g- 1TS. No antibiotic residues detected in the biogas fermentation residue after fermentation,which indicated that the mesophilic anaerobic digestion methods was feasible to make the cephalosporin bacterial residue harmless and recycling.
