| 摘 要： | 利用上向流生物曝气滤池（UBAF）对微污染水源水去除氨氮及有机物进行了中试研究。研究表明，UBAF对氨氮、亚硝酸盐、Mn^2＋均有较高的去除率，尤其是具有较强的硝化能力，在进水氨氮为6mg／L左右、滤速为8m／h的水力负荷下，UBAF对氨氮去除率大于88％；在氨氮进水为2mg/L时，UBAF可在滤速为16m/h的水力负荷下运行，去除率大于84％。UBAF对高锰酸盐指数的去除率平均10％，对AOC的去除率为58％。经UBAF预处理后，混凝剂投加量可节省30％左右。UBAF对水中的三氯甲烷前体物去除率较低。

| Abstract: | A pilot research on removals of ammonia-nitrogen and organics from micro pollution water source by UBAF was carried out. It was showed that UBAF had high removal rate for ammonia-nitrogen, nitrite and Mn; specially it had stronger nitrification ability; under the conditions of influent ammonia-nitrogen being 2mg/L, UBAF could operate under the hydraulic load of flow rate 16m/h and the removal rate was greater than 84%. The removal rate of permanganate index by UBAF averaged 10%; the removal rate of AOC was 58%; after pretreatment by UBAF, the dosage of coagulant could save by about 30%; the removal rate of chloroform in water by UBAF was lower. |
