REAKTOR ZUR BIOLOGISCHEN REINIGUNG VON SCHADSTOFFHALTIGEM WASSER IM SCHLAUFENBETRIEB.

摘要

A loop reactor (1) for the biological purification of polluted water is composed of a closed cylindrical vessel (2) in which there is arranged concentrically a flow guide pipe (5) into which liquid can flow at the bottom and which can overflow at the top. Both the vessel (2) and the flow guide pipe (5) are composed of prefabricated reinforced concrete pipes of a uniform diameter in each case, which prefabricated pipes are connected together pressure-tightly at the ends with the insertion of joint seals. Both the vessel (2) and the flow guide pipe (5) rest on a shared foundation (3) and are covered by a lid (4). This loop reactor is suitable for temporary use for purification of soils or water on-site; it can be dismantled after completion of the work.
