摘要
      研究了35°C（中温）和55°C（嗜热）厌氧处理猪粪对甲烷产生、微生物群落和新出现的污染物的影响。还研究了巴氏灭菌预处理和后处理与35°C厌氧处理相结合的情况。评估了比甲烷产量（SMP）、26种药物化合物（PhAC）和5种抗生素抗性基因（ARGs）（qnrS、tetW、ermB、sul1和blaTEM）。无论是否进行巴氏灭菌，嗜中温处理都能产生最高的SMP。马波沙星是猪粪中含量最高的抗生素。一般来说，与中温温度相比，所有组的PhAC在高温温度下都表现出更高的去除率。一般来说，巴氏灭菌预处理和中温厌氧消化对ARGs的去除率最高。最后，猪粪中存在链球菌属、梭菌属和假单胞菌属，它们含有致病物种。链球菌是最丰富的，在所有的治疗过程中都减少了，而其他的只有在某些治疗下才会减少。
Abstract
The effect of anaerobic treatment of swine manure at 35 °C (mesophilic) and 55 °C (thermophilic) on methane production, microbial community and contaminants of emerging concern was investigated. Pasteurization pretreatment and post treatment was also investigated in combination with anaerobic treatment at 35 °C. Specific methane production (SMP), 26 pharmaceutical compounds (PhACs) and five antibiotic resistance genes (ARGs) (qnrS, tetW, ermB, sul1 and blaTEM) were evaluated. Mesophilic treatment resulted in the highest SMP regardless of whether pasteurization was applied. Marbofloxacin was the most abundant antibiotic in swine manure. In general, all groups of PhACs showed higher removals under thermophilic temperatures as compared to mesophilic. In general, pasteurization pretreatment followed by mesophilic anaerobic digestion provided the highest removals of ARGs. Finally, the genera Streptococcus, Clostridium and Pseudomonas which contain pathogenic species, were present in the swine manure. Streptococcus, which was the most abundant, was decreased during all the treatments, while the others only decreased under certain treatments.
