| 摘要: |
| 为提高普通曝气生物滤池除磷效果,以水渣为主要原料开发了一种CaCO3型生物滤料,并以陶粒为参比滤料,通过改变水力停留时间考察CaCO3型生物滤料和陶粒两种填料的曝气生物滤池除磷特性．结果表明,与陶粒填料相比,CaCO3型生物滤料曝气生物滤池对磷具有较好的去除效果,在水温为20～25 ℃、COD负荷为3.55～3.62 kg·(m3·d)-1、氨氮负荷为0.76～0.78 kg·(m3·d)-1条件下,CaCO3型生物滤料曝气生物滤池在HRT为5,3和1 h时,磷去除率分别为65.20％～71.07％、40.49％～48.02％和26.10％～33.11％．CaCO3型生物滤料曝气生物滤池对磷的去除主要是通过生物诱导化学沉淀来实现,且磷酸钙盐沉淀对出水浊度几乎没有影响． |

| Abstract: |
| By comparative studies on BAF between CaCO3-biofilter media which is a new-style filter material made of grain-slag and ceramisite filter material, the performance of phosphorus removal was discussed at different HRT and phosphorus concentrations. The results indicated that compared with ceramisite filter material, CaCO3-biofilter media had a higher removal rate of phosphorus in BAF. Under the condition of water temperature of 20-25 ℃, ammonia nitrogen load rates of 0.76-0.78 kg·(m3·d)-1and organic load rates of 3.55-3.62 kg·(m3·d)-1, the phosphorus removals of CaCO3-biofilter media biological aerated filter with HRT 5,3 and 1 h were in the range of 65.20％-71.07％, 40.49％-48.02％ and 26.10％-33.11％ respectively. It was evidenced that CaCO3-biofilter media biological aerated filter could remove phosphorus effectively by biologically-induced chemical precipitation and the settling matters had no effect on the effluent turbidity. |
