| 摘 要： | 饮用水中微量有机物的污染是关系饮用水生态安全的重要问题。以饮用水中微量的内分泌干扰类除草剂阿特拉津为研究对象，分别采用微生物降解技术和光催化氧化技术对其进行降解，考察温度对阿特拉津降解效果的影响。研究结果表明：阿特拉津浓度为1 mg/L时，3种温度条件下，除锰功能菌MB4对阿特拉津均有明显的去除效果，降解时间为7 d时，阿特拉津的去除率达到65%。底物浓度为200 μg/L，3种温度条件下，活性炭负载二氧化钛（TiO2/PAC）催化剂光降解阿特拉津30 min时，其去除率均达到90%。光催化氧化技术协同微生物降解技术在饮用水中微量的内分泌干扰物的去除中有广阔的应用前景。 |

| Abstract: | Drinking water pollution caused by micro organics is one of key issues on the ecological safety.The endocrine-disrupting pesticide atrazine in drinking water was selected as target in the paper,and microorganism and photocatalysis degradation techniques were separately applied in its removal,and influence of temperature on the degradation efficiency was examined.It was indicated that the Mn-removal functional bacterial MB4 had obvious role in removal of atrazine when its initial concentration was 1 mg/L at ... |
| Keywords: | organic micro-pollution microorganism degradation photocatalysis removal technique |
