【摘要】 该文针对微污染原水,采用预处理+常规处理+臭氧-生物活性炭工艺流程进行中试试验研究。着重考察高铁酸钾、臭氧、二氧化氯和后续臭氧-生物活性炭工艺对水中有机物和氨氮的去除效果。结果表明,三种氧化剂对水中有机物和氨氮的去除,除了经过预臭氧化后,氨氮浓度不仅没有下降反而上升之外,其余具有不同程度的去除效果,臭氧-生物活性炭工艺对水中有机物和氨氮的去除效果均相对较高。更多还原

【Abstract】 Based on the micro polluted raw water, the pretreatment + conventional treatment + ozone- biological activated carbon process were doted in a pilot test. Focusing on the removal effect of organics and ammonia nitrogen in water by potassium ferrate, ozone, chlorine dioxide and subsequent ozone- biological activated carbon process. The results showed that, three kinds of oxidant on the organic matter and ammonia nitrogen in water removal, in addition to the pre ozonation, ammonia concentration was not decreased but increased, the removal of different degree, ozone biological activated carbon process of the organic matter and ammonia The results showed that, three kinds of oxidant on the organic matter and ammonia nitrogen in water removal, in addition to the pre ozonation, ammonia concentration was not decreased but increased, the removal of different degree, ozone biological activated carbon process of the organic matter and ammonia nitrogen in water removal, the removal effect was relatively high.更多还原
