综合厌氧处理乳品工业废水和污泥------外文翻译.doc

ABSTRACT
Performance parameter were studied in an alternative full-scale dairy effluence treatment system comprising two anaerobic sludge-blanket reactors in parallel arrangement with upward flow，internal fat-separation by flotation，external lamella settler and floated material digester. Reactors were initially inoculated sludge and granulated in a high-load stage. Using loading rates up to a maximum 5.5kgCOD/m3.d-hydraulic residence time of 17hours-reactor efficiency was found to remain stable around 90% of COD. Average sludge digester efficiency using a loading rate of 3.5kgVS/m3．d with a lipid content of 47% of COD amounted to 78% of VS（87% of lipid removal）．LCFA inhibition as assayed using palmitate was found to depend not only on the palmitate concentration but also on the palmitate-to-biomass concentration ratio.


摘要：人们研究了一个替代的乳品污水处理系统的性能参数，该系统包括两个厌氧污泥反应器，均安排向上流动，内部脂肪分离浮选，外部板定居和浮动材料沼气池。反应器最初接种高负荷的絮状和粒状污泥。使用负荷率最高达5.5kgCOD/m3.d ，水力停留时间17小时，发现反应器仍能稳定去除90%的COD。长链脂肪酸的测定使用抑制棕榈酸脂，然而现在发现不仅取决于棕榈酸酯的浓度，而且还跟棕榈酸酯的生物量浓度比有关。
