畜牧业每年将生产240亿吨废水，废水的排放导致水资源的严重富营养化。此外，集中饲养动物的大型农场需要大量使用激素和抗生素，对周围的淡水生态系统等产生负面影响。比如，畜牧业废水中的厌氧消化后的出水的主要特点包括1）氨氮浓度高（1000-2000 mg/L），2）抗生素种类繁多，且3）碳氮比（C/N<1）往往低于传统活性污泥所需的营养比例（C/N >5）。因此，厌氧消化后的水不利于后续活性污泥法的反硝...
浙江大学生命科学学院吕镇梅课题组在Environmental Science & Technology发文揭示新污染物三氯生的起始降解分子机制（图）
吕镇梅 污染 分子机制 代谢 酶学催化
2024/10/19
2024年来，水环境中新污染物大量排放，对水生生物和人体健康存在潜在威胁，其治理已成为我国可持续发展的重大战略需求。三氯生是一种人工合成的抗菌剂类新污染物，广泛分布于各种水环境中，且残留的三氯生不易被降解，危害水生生物和人类健康。目前，三氯生的微生物分解代谢机制尚未被解析，研究三氯生的微生物分解代谢及酶学催化机制，对去除其在环境中的污染具有重要意义。
