Abstract

In the purification of carbohydrate- and/or protein-rich effluent, the effluent is treated in an anaerobic stage (1), methane gas formed being discharged (2). The sludge-containing water formed is subjected to a sludge separation (3), a first sludge concentrate resulting which is returned to the anaerobic stage (1). The water separated off is treated in an aerobic stage (7) and the sludge-containing water formed is subjected to a sludge separation (8) to form a second sludge concentrate, of which a part is returned to the aerobic stage (7), while excess is passed back to the anaerobic stage (1). A part of the first sludge concentrate is discharged for disposal. When the process is applied for example to effluent from sugar, starch or canning factories, the two biological processes proceed with great stability and with good purification action. Moreover, the amounts of biological sludge are only a fraction of the conventional amount of sludge. The solids are easily removed for example by sedimentation from the effluent. <IMAGE>
