摘　　要：中国已经成为了世界上抗生素原料药生产的主要国家之一,青霉素菌渣产生量大、不易处理,而且是危险固体废物,为减少其对环境的危害,对其嗜热溶胞菌生物减量化进行了研究,考察了温度及嗜热溶胞菌液含量对其减量化效果的影响。实验结果表明:嗜热溶胞菌能有效提高菌渣胞内有机物的溶出,接种10%嗜热溶胞菌,在50、60和70℃下SS、SCOD和NH_4^+-N的结果表明:60℃条件下减量效果最好,SS去除率达到32.47%,SCOD由1 015 mg/L增长到1 714 mg/L,NH_4^+-N增量最高,达2.71 mg/L。接种0%、5%、10%、15%和20%嗜热溶胞菌在60℃下SS、SCOD和NH_4^+-N的结果表明:菌液含量为5%时,SS去除率较高,SCOD最大值达1 726 mg/L,加菌下的NH_4^+-N浓度要高于未加菌下的NH_4^+-N浓度。可见,在适宜的条件下,嗜热溶胞菌对青霉素菌渣具有减量化效果,且在60℃,菌液含量为5%时减量效果最佳。China has become one of the major countries in the world of penicillin bacteria residue which is a kind of dangerous solid waste. The reduction effects of temperature and inoculation amounts of thermophilic bacteria were examined to reduce its harm to the environment. The results showed that the thermophilic bacteria can improve dissolving the organic matter from intracellular through determination of inoculation 10% thermophilic, 1.0 kg COD/（m3·d） penicillin bacteria residue in the change of SS, SCOD and NH4＋-N concentration under the temperature of 50 ℃, 60 ℃ and 70 ℃, respectively. Under the condition of 60 ℃, the removal rate of SS concentration reached 32.47%, SCOD concentration by the beginning of 1 015mg/L reached up to 1 714 mg/L, NH4＋-N concentration increased the highest, which was enhanced by 2.71 mg/L. The change of SS, SCOD and NH4＋-N concentration in thermophilic bacteria with the concentration of 0%, 5%, 10%, 15% and 20% at 60℃, showed that the removal rate of SS concentration was higher and SCOD reached the maximum 1 726 mg/L when adding quantity of bacteria 5% first. In the whole process of anaerobic digestion, the concentration of NH4＋-N was higher than that without inoculated with bacteria.
