摘　　要：在NH3N平均容积负荷为0.3kg/(m3·d),DO为0.7～1.1mg/L,污泥质量浓度为3.3～3.9g/L,没有对pH进行调节的条件下,研究了温度对亚硝酸氮积累的影响。试验结果表明:当温度达到一定条件时,亚硝酸氮的积累不再随温度升高而增加的主要原因是游离亚硝酸的抑制作用。针对“中老龄”垃圾渗滤液特定的水质特点,建议将温度设在25～30℃为宜。The effects of temperature on nitrate accumulation are investigated under the given conditionsaverage ammonium load of NH 3N0.3 kg/(m 3·d),DO concentration 0.7～1.1mg/L,MLSS concentration 3.3～3.9g/L and no pH adjustment.The results show that nitrate accumulation will not increase with the increase of temperature mainly due to the inhibition of free nitric acid when temperatures reach a certain level.As to the specific water quality characteristics of mature leachate,it is proposed that the temperature is set at 25℃～30℃.
