摘要
马铃薯加工废水中有机物和悬浮固体的浓度都比较高。为了探讨一种高效稳定的处理方法，在新布伦瑞克大学实验室利用上流式厌氧污泥床──厌氧滤柱系统，进行了低负一荷条件下两级厌氧处理的研究。运行试验长达４２０天，结果表明：在常温条件下，该系统的有机负荷为０．１９～０．５５ｋｇＣＯＤ／ｍ３ｄ时，ＣＯＤ和ＳＳ的去除率分别是９５～９８％和９８～９９％，产气量为０．３１～０．３２ｍ３ＣＨ４／ｋｇＣＯＤ去除，运行期间出水水质始终良好，没有出现任何恶性变化的征兆。
The potato-processing wastewater contains a high concentration of biodegradable materials and suspendedsolids.Two stage anaerobic treatment process,consisting of up flow anaerobic sludge blanket(UASB)and upflowapaerobic filter(UAF)was used at low organic loading;this study wad catTied out in the laboratory of Universityof New Brunswick,Canada to find an effective and stable method. The.overall length of the study lasted for 420days.UASB-UAF system was able to remove 95%-98% of COD and 98-99% of ss with the organie loading of 0,19-0.55 kg COD/m3.d at 20℃.Biogas produced by the system was 0,31-32m3CH/kg COD.The effluehtwas stable in quality and no sign of deterioration was observed during the operation period
