近年来，已经开发了许多设计用于废水的高速厌氧处理（1-6）。所有这些方法都有它们的优点和缺点，这已经被反复讨论过了（例如，见7）。在这些工艺中，上流式厌氧污泥床（UASB）工艺目前应用最广泛，至少在西欧是这样。它已成功应用于玉米和马铃薯淀粉工业以及甜菜和马铃薯加工工业的废水处理（8）。UASB工艺的主要优点可能是不需要特定的支持材料。然而，这一主要优点有时可能是一个严重的缺点：缺乏支持材料，需要有一个非常好的沉降性能污泥的可用性。无论何时获得这种污泥，或者可以保持这种污泥，都容易实现UASB工艺的成功操作。
In recent years, numerous designs have been developed for the high rate anaerobic treatment of wastewater (1-6). All these processes have their advantages and drawbacks, which have been discussed repeatedly (see, for instance, 7). Of these processes the upflow anaerobic sludge blanket (UASB) process is currently the most widely applied, at least in Western Europe. It is successfully applied in the treatment of wastewaters from maize and potato starch industries, and sugar beet and potato processing industries (8).Perhaps the main advantage of the UASB process is that no specific support material is required. However, this main advantage may sometimes be a serious drawback: the absence of support material necessitates the availability of a sludge with very good settling properties. Whenever such a sludge is obtained, or can be maintained, successful operation of the UASB process is readily achieved.
