摘要
介绍东深供水工程生化预处理挂膜启动过程中 ,氨氮、CODMn去除效果和填料上生物膜变化的特点。根据氨氮去除率 (≥ 50 .0 % )、生物膜形状、生物膜上动物种类和数量可判断挂膜启动过程是否完成。本试验挂膜启动 2 5天 ,比小型试验增加了 1 0天左右 。
It has been discussed in this paper that removal rates of ammonian and COD Mn are influenced by the characters of bio film hanged to carrier, during the biochemical pretreatment of supply water project of Dongjiang Shenzhen. Bio film culture process is estimated by the shape of bio film, sorts and number of the animalcules and the removal rates ( ≥50.0 %)of ammonian. The time for succeed industrial test is 25 day and the lab succeed test is only 14 day because the temperature was lower during industrial test.
