摘要
通过测定有机物生物降解过程中微生物的能量变化──ＡＴＰ含量的变化来表征有机物的好氧生物降解性。采用受试物的初始浓度为１００ｍｇ／Ｌ溶解性有机碳（ＤＯＣ），接种生物量为５００ｍｇ／Ｌ，试验周期１４ｄ，取得了较好的试验结果。给出了测试程序，采用峰值时间、峰高指数、ＩＡ指数作为定量评价指标，从而建立了ＡＴＰ评价方法，并对４６种有机物和７种废水的好氧生物降解性进行了评价。
In this paper,the aerobic biodegradation of organic substances is charactered by the determination of the energy change,ATP content in microbial cells during the biodegradation.A satisfactory result was obtained under the following conditions:the initial concentration of the tested substance is 100 mg/L(as DOC),the amount of the inoculum in the biological medium is 500 mg/L(as MLSS),and the duration of test time is 14 days.The evaluating system(peak time,peak height index and IA index) is proposed to assess the biodegradability of 40 organic subStances and 7 wastewater.
