【摘要】 采用悬浮填料移动床工艺处理苏州河支流河水 ,试验结果表明 ,填料填充率为 5 0 % ,水力停留时间为 1h ,进水CODCr44— 2 32mg/L ,BOD519— 10 1mg/L时 ,出水CODCr34.1mg/L ,BOD59.1mg/L。在适宜的水温条件下 ,进水氨氮≤30mg/L ,水力停留时间为 1.5h ,亦能取得较好的氨氮去除效果更多还原

【Abstract】 In this paper the treatment of the branch water of Suzhou River by using suspended filler moving bed was presented. The results showed that the effluent COD Cr concentration averaged 34.7mg/L, BOD 5 9.1mg/L under the conditions of COD Cr feed 44-232mg/L, BOD 519-101mg/L, the filling proportion of filler 50% and hydraulic retention time (HRT) 1 hr. It could also gain very high nitrification efficiency when the water temperature was suitable.更多还原
