【摘要】 通过MBBR工艺和陶粒生物滤池预处理黄河中下游微污染黄河水的对比试验研究,发现陶粒生物滤池和移动床生物膜反应器对CODMn的去除效果接近,但前者对UV254、三氯甲烷前体物和叶绿素a的去除效果均远远高于后者。陶粒生物滤池对氨氮的去除效果略高于移动床生物膜反应器,陶粒生物滤池出水中的亚硝酸盐氮浓度也较低。更多还原

【Abstract】 COD_Mn removal by bio-ceramic filter was similar to that by moving bed biofilm reactor,however,the former process demonstrated a much higher removal efficiency of UV₂₅₄,chloroform precursors and chlorophyll a（Chla）.Bio-ceramic filter also had better ammonia removal rate and nitrite in its effluent was lower.更多还原
