论文选择当前微污染水源饮用水处理中的两种常见填料与三种典型的生物处理方式,在同一水源现场条件下进行中试规模的比较研究,得出了以下主要结论:(1)指出生物预处理是综合改善微污染水源水质的有效方法。所研究的两种填料、三种生物预处理方式中,淹没式曝气生物滤池(Ⅰ型)的净 The paper chooses two kinds of common fillers and three typical biological treatment methods in current micro-polluted drinking water treatment, and makes a comparative pilot scale study under the same water field conditions. The main conclusions are as follows: (1) Pretreatment is an effective way to improve the quality of slightly polluted water. Of the two types of packing studied, among the three types of biological pretreatment methods, the submerged aerated biological filter (type I)
