Abstract

A set of ten upflow sludge blanket digesters was examined as five pairs (one control and four test reactors) to assess the way in which controlled nutrient variations affected the performance of the reactors in treating a simulated ice-cream wastewater. An alternative carbon source was used and additional concentrations of calcium and cobalt were examined. The results show that the waste itself is capable of being treated by the UASB process, with granulation commencing after 60–70 days. However, of the supplements, only calcium had any significant effect.

用UASB工艺厌氧消化冰淇淋废水
一组10个上流式污泥毯式消化器被检查为五对(一个对照和四个试验反应器),以评估控制营养变化影响反应器处理模拟冰淇淋废水的性能的方式。使用了另一种碳源,并检查了钙和钴的额外浓度。结果表明,废水本身可以通过UASB工艺处理,60-70天后开始造粒。然而,在补充剂中,只有钙有显著的效果。
