摘要
试验结果表明 ,软性载体淹没序批式生物膜法是行之有效的除磷工艺。在载体装填密度为 30 %、水力停留时间为 9h(其中厌氧 3h、好氧 6h)、进水COD负荷为 0 .2 7～ 1.32kgCOD/(m3·d)时 ,磷的去除率达 90 %以上。试验中 。
The study result showed that the sequencing batch reactor of submerged biofilm process with fibrous carriers is effective in phosphorus removal. When the carrier packing percentage is 30%, hydraulic retention time ( HRT ) is 9 h (including 3 h for anaerobic zone and 6 h for aerobic zone), and influent loading rate is 0.27～1.32 kgCOD/(m 3·d), over 90% of phosphorus removal is achieved. In the test, a systematic analysis was also made for the factors affecting phosphorus removal.
