摘　　要：通过实验研究比较了污泥好氧消化与好氧厌氧交替消化之间的MLSS,MLVSS,TN去除率以及上清液中NH4+—N质量浓度,pH值的变化情况.实验结果表明,好氧厌氧交替消化与好氧消化相比较,MLSS,MLVSS的去除率相差不大,说明好氧厌氧交替消化同样具有较好的污泥减量效果.同时相对好氧消化来说,好氧厌氧交替消化具有TN去除率高,上清液中NH4+—N质量浓度较低,pH值稳定等特点.This paper discusses the different reduction rate of MISS, MLVSS and TN as well as the variation of NH4^＋ -N concentration and pH value in the supernatant through experiment data for both aerobic digestion and aerobic-anoxic sludge digestion. From the experiment data, the conclusion can be made that comparing with aerobic digestion, aerobic-anoxic digestion has a almost equal MISS, MLVSS reduction rate, a higher TN reduction rate and a more stable NH4^＋ -N concentration and pH value.
