  • 摘要: 立体浮床是一种新型的生物预处理方法。采用了"曝气充氧+新型立体浮床"强化处理方法治理微污染河水,对立体浮床挂膜期间底部填料上的生物膜特性及微污染河水处理效果进行了实验研究。结果表明,在河道水温为15.2~23.6℃,pH在7.0~7.8,溶解氧浓度为4.0~5.9 mg/L时,经40 d左右时填料挂膜成熟。通过对水质和微生物指标分析,填料挂膜分为4阶段:物理吸附阶段—物理吸附-生物繁殖阶段—生物强化吸附降解阶段—挂膜成熟阶段。填料挂膜成熟后,污染物去除效果良好,浊度、COD和NH3-N的去除率分别达到了20.1%、17.5%和18.3%。
    Abstract: Tridimensional floating bed is an innovative type of biological pretreatment. This test used an enhanced treatment composed of aeration system and new tridimensional floating bed for micro-polluted river water purification. The biofilm characteristics on the packing and purification of the water during biofilm colonization were studied. The results showed that when temperature was 15.2~23.6℃,pH was 7.0~7.8, dissolved oxygen was 4.0~5.9 mg/L, it took approximately 40 days for the biofilm maturation. Based on the analysis of water quality and microbial indicator, the process of biofilm colonization could be divided into four stages including physical adsorption, physical adsorption with rapid proliferation of microbes, enhanced adsorption and degradation by microbes, as well as the biofilm maturation. After maturation of biofilm, the removal efficiency of turbidity, COD and NH3-N could reach 20.1%,17.5% and 18.3%, respectively, showing a high purification efficiency.
