摘要： The invention relates to a method and device for effluent treatment, whereby the effluent (6) to be treated is biologically purified in a fixed-bed (1), in particular, a trickling filter and the output (12), from the fixed bed (1) is subjected to a dead-end membrane filtration (2) and the retained solids removed by back-flushing. Effluent (6) can, thus, be purified using a fixed-bed (1) to such a degree that the quality of the treated effluent allows it to be used as water supply, in particular, for irrigation purposes. Furthermore, filtration by means of the dead-end principle has the advantage of a low energy requirement in comparison with a cross-flow operation and a dead-end membrane filtration plant requires less space than a conventional clarifying basin and sand filter.

摘要翻译： 本发明涉及一种用于流出物处理的方法和装置，其中待处理的流出物（6）在固定床（1），特别是滴液过滤器和输出（12）中从固定床 （1）进行死角膜过滤（2），并通过反冲洗除去残留的固体。 因此，可以使用固定床（1）净化出流出物（6），使得经处理的流出物的质量允许其用作供水，特别是用于灌溉目的。 此外，通过死路原理的过滤具有与交叉流动操作相比低能量需求的优点，并且死端膜过滤设备比常规的澄清池和砂过滤器需要更少的空间。
