Biological active parameters during aerobic digestion of excess acti-vated sludge such as Dehydrogenase Activity ( DH A ), Oxygen Uptake Rate ( OUR ) and Mixed Liquor Volatile Suspended Solid(VSS) ( MLVSS ) was determined and analysed. 测定和分析了剩余污泥好氧消化的生物活性参数脱氢酶活性(DHA)、氧摄取速率(OUR)以及混合液挥发性悬浮固体(MLVSS)。
The volatile suspended solid ( VSS ) concentrations were different in different compartments, the first two compartments had higher VSS concentration. 反应器不同格室的挥发性悬浮固体(VSS)浓度也明显不同,前面格室的VSS高于后面格室。
The remarkable effects of reactor temperature on the removal of volatile suspended solid ( VSS ) were obtained. And a higher reactor temperature produces a higher removal of VSS. 试验发现①反应温度对挥发性的有机物的去除有显著影响,反应温度越高,VSS去除率越高。
