Reactors for the anaerobic purification of waste water which operate by the UASB process (Upflow Anaerobic Sludge Blanket) have at the top separating modules for separating the three phases resulting from the purification: a plurality of immersed collecting hoods (14), which are arranged in a stack, for the biogas, extractors, which are located above the water level, for waste air, and a discharge, which is located under the water level, for the purified waste water. The innovation in these modules is the fact that all the walls, covers and inbuilt components (13-15) of the module consist of plastic reinforced with steel profiles, and that all the discharge lines (17, 18, 19) open out of a narrow side of the module and are connected to channels (8) which are located outside the modules and can be closed in sections. The novel design makes it possible for each module to be removed and undergo maintenance without interrupting operation. |
