Apparatus for anaerobically fermenting sewage water and a method for a combined anaerobic / aerobic fermentation of sewage water.

摘要

A method and equipment for a combined anaerobic/aerobic fermentation of sewage water wherein sand and primary sedimentation material are removed in one step by passing the sewage water through a reactor which can be tilted so that its centre line is inclined at 10 to 80 DEG and which has a length : diameter ratio of at least 1:1, which reactor is provided with at least one feedpipe and one discharge pipe and which contains a system of at least 2 foam material layers consisting of open-cell polyurethane foam material situated against each other, each having a flat main surface and a main surface profiled virtually in the direction of the main axis of the reactor in multi-channel form, the profiled surface of a foam material layer being situated in each case in successive layers against the flat surface of the adjacent foam material layer to collect the sludge sliding to the bottom of the reactor and to drain the collected sludge from time to time.
