| 摘 要： | 基于理论分析,提出CODCH4/COD值作为废水厌氧可生化性的评价指标,确定了CODCH4/COD值表示厌氧可生化性的数值界限。同时,在BMP分析的基础上,采用CODCH4/COD值考察了垃圾渗滤液的厌氧可生化性,并与BOD5/COD值评价结果进行了对比。实验结果显示,CODCH4/COD值与BOD5/COD值用于垃圾渗滤液可生化性的评价,得出的结论具有相似性,但CODCH4/COD值大于BOD5/COD值。究其原因:好氧条件下,总的生化耗氧量(BOD)u小于理论完全需氧量(COD);厌氧条件下,有机物完全去除时CODCH4(理)等于理论完全需氧量。此外,BOD5测试时间仅5 d,而BMP测试时间一般在30 d以上,从而使微生物有足够的时间去适应废水水质,故能较好地反映废水的可生化性。

| Abstract: | On the basis of theoretical analysis,CODch4 /COD as wastewater anaerobic biodegradability index was presented,and the bound of numerical value was determined.At the same time,leachate of a landfill in Chengdu was collected as a subject of case study.Anaerobic biodegradability of the landfill leachate was appraised by CODCHch4/COD through biochemical methane potential(BMP) test.Results evaluated respectively by CODCHch4/COD and BOD5 /COD were compared.It was found that a similar conclusion was obtained for t... |
