摘要
在常温 2 5℃采用两相厌氧法对养鸡场离心废水进行处理 ,结果表明 :进水 CODcr为 1 830 0m g/ L,系统容积负荷 1 7.2 6 kg CODcr/ m3· d,水力停留时间 2 5 .47h,CODcr去除率为 76 .1 3% ,BOD5 去除率为 87.76 % ,产气率为 0 .41 0 m3/ kg CODcr.
Study on the treatment of centrifugal effluent from laying hen manure mixing liquid is presented by two phase up flow anaerobic sludge blanket reactor(UBF)at 25℃.The results of the experiment are asfollows:influent COD cr concentration 18.3×10 3mg/L,volumetric loading rate is 17.26 kg COD cr /m 3·d,hydraulic retention time is 25.47 h,the removal rate of COD cr is 76.13%,that of BOD 5 is 87.76%,and biogas production rate is 0.410 m 3/kg COD cr .
