APPARAT ZUR ELEKTROCHEMISCHEN ABWASSERREINIGUNG

摘要

The apparatus according to the invention consists of a settling chamber (1) with outflow ports (6 and 7) for clear water and sludge, respectively, and of an electrocoagulation chamber (2) arranged in the settling chamber (1) and connected thereto. The electrocoagulation chamber (2) contains an inflow port (4) for effluent, an inflow port (5) for electrolyte and a number of soluble electrodes (3). These are situated below the inflow port (4) for effluent. Arranged in the wall of the electrocoagulation chamber (2), distributed over the circumference and below the water level of the settling chamber (1) there are orifices (10) into which nozzles (12) of injectors (11) debouch which feed part of the foam from the electrocoagulation chamber (2) to the settling chamber (1). The invention is used for the electrochemical cleaning of industrial effluents.
