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：人們研究了一個替代的乳品污水處理系統(tǒng)的性能參數(shù)，該系統(tǒng)包括兩個厭氧污泥反應器，均安排向上流動，內(nèi)部脂肪分離浮選，外部板定居和浮動材料沼氣池。反應器最初接種高負荷的絮狀和粒狀污泥。使用負荷率最高達5.5kgCOD/m3.d ，水力停留時間17小時，發(fā)現(xiàn)反應器仍能穩(wěn)定去除90%的COD。長鏈脂肪酸的測定使用抑制棕櫚酸脂，然而現(xiàn)在發(fā)現(xiàn)不僅取決于棕櫚酸酯的濃度，而且還跟棕櫚酸酯的生物量濃度比有關。
