摘　　要：利用中试装置研究了水源水阿特拉津突发污染的应急处理措施。试验结果表明:常规工艺不能有效去除原水中的阿特拉津,投加粉末活性炭(PAC)可有效去除阿特拉津,确保出水达到水质标准的要求;PAC投量为50mg/L时,可使初始浓度为200μg/L的阿特拉津降低到2μg/L以下;KMnO_4与PAC联用的去除效果比单独使用PAC略有改善但并不显著,预氯化则会降低PAC对阿特拉津和UV_(254)的去除率。Emergent treatment of herbicide atrazine polluted source water was researched by pilot plant. The results showed that atrazine couldn＇t be removed effectively to get outflow comply with the requirement of water quality standard by conventional water treatment, so PAC （powdered activated carbon） was used. When the PAC dosage was 50 mg/L, the atrazine content in polluted source water could be decreased from 200 μg/L to below 2 μg/L. The removal efficiency of PAC combined with KMnO4 was a little but not much better than PAC alone. Prechlorination could reduce the removal efficiency of atrazine and UV2s4 by PAC.
