摘要
为了探索饮用水生物预处理的可行性，进行了国内第一家生产规模饮用水生物接触氧化预处理装置试验．试验表明：在水气比１∶１、滤速３．６－６．０ｍ／ｈ时，生物预处理对水源水中有机物（ＯＣ）和氨氮的去除效率分别为１３．６％－２０．５％和７０％－９０％；影响生物预处理运行效果的主要因素是溶解氧和温度．
In this study,the test of full scale biological contact oxidation pretreatment in drinking water treatment was discussed, which is first in domestic. The results demonstrated that biological pretreat process can remove organic compounds and ammonia of source water by 13.6%- 20.5% and 70%- 90% respectively when the ratio of water to air is 1∶1; the key factor to affect the biological pretreat process performance is dissolved oxygen and temperature.
