| 摘 要： | 氨吹脱作为猪场沼液的预处理方法,其处理效果受填料等多种因素的影响。分别采用空心多面球、鲍尔环和流化床填料在pH值10.5,气液比2000,温度30℃的条件下吹脱猪场沼液,结果表明:空心多面球和流化床对沼液氨氮(ammonia nitrogen,NH4+-N)的平均去除率显著高于鲍尔环填料(P0.05),吹脱2 h,氨氮的平均去除率分别为80.7%、59.0%和77.4%。投加NaOH使沼液化学需氧量(chemicaloxygendemand,COD)因压缩双电层和混凝而降低,总固体(totalsolid,TS)和挥发性固体(volatilesolid,VS)因OH-对微生物结构的破坏和大分子物质的水解而增加。吹脱过程使COD部分提高,而TS和VS有所降低。3种填料的性能参数差异导致吹脱后沼液COD平均去除率的变化和VS的平均去除率不同,但不存在显著差异(P0.05),流化床填料对TS的平均去除率显著高于空心多面球(P0.05)。选定空心多面球吹脱20 L沼液2 h,1 L的1 mol/L硫酸吸收液对吹脱尾气中氨气的平均吸收率为35.8%,兼顾吸收效果和经济性。
