摘要： A solid-bed reactor for biological sewage treatment has an intermediate floor which carries floor jets and by means of which the solid bed can be backwashed. The intake for the sewage is above the solid bed. Aeration orifices are integrated into the floor jets, and gas bubbles can be introduced by the orifices in the upper portions of the floor jets without thereby giving rise to instability phenomena. To ensure stable uniform distribution of aeration throughout the reactor, the clear cross-section in the entire intake region of each floor jet must be such that above the aeration orifices the flow of outgoing water does not impede the ascent of the gas bubbles.

摘要： The drainpipe is of triangular cross-sectional shape and has an oblong slot in the bottom surface which is closed over by a stepped ledge having webs and grooves. The slot and grooves in the ledge form a flow connection between the filter basin and the interior of the drainpipe. The drainpipe is simple to manufacture and dead zones in the filter mass not wetted by the flushing media during back flushing are completely avoided or reduced to a minimum.
摘要翻译：排水管具有三角形横截面形状，并且在底表面中具有长方形的槽，其由具有腹板和凹槽的阶梯式凸缘封闭。突出部分中的槽和槽在过滤器盆和排水管的内部之间形成流动连接。排水管易于制造，反冲洗过程中未被冲洗介质润湿的过滤器块中的死区完全避免或降至最低限度。
