摘要
采用常温２５℃，改变ＮＨ３—Ｎ浓度，通过ＵＢＦ反应器对鸡粪混合液离心出水进行处理．试验结果表明：ＮＨ３—Ｎ对鸡粪混合液离心出水的厌氧生物处理具有抑制作用，２５℃时ＮＨ３—Ｎ的抑制浓度为１６００ｍｇ／Ｌ，游离氨（ＮＨ３）的最大承受能力为１１０ｍｇ／Ｌ．
In this paper, a study of inhibiting action of ammonia nitrogen by changing NH 3 N concentration in UBF reactor at 25℃ is presented. The results of the experiment are as following: an NH 3 N concetration exceeding in a threshold level causes inhibition to the anaerobic biological treatment of centrifugal effluent from laying hen manure mixing liquid. At 25℃, an NH 3 N concentration exceeding in 1600mg/L causes inhibition, and an NH 3 concentration exceeding in 110 mg/L causes inhibition.
