Embodiment

[0157] Apparatus for implementing the method of the invention

[0158] exist figure 1 An exemplary embodiment of the device (100) of the present invention is shown in . The device is composed of a bioreactor (1), a filter device (2) and a photobioreactor (3). The bioreactor (1) and the filter unit (2) are connected to each other via a pipe (12). The filter device (2) and the photobioreactor (3) are also connected to each other via pipes (23).

[0159] The bioreactor ( 1 ) can be designed, for example, as a digestion column and have means for mixing the reactor contents, eg stirring means ( 11 ). Anaerobic biological purification of organic suspensions such as waste water is carried out in the bioreactor (1). The biogas generated here can be exported and used to generate energy. CO produced when energy is produced from biogas 2 can be fed to the photobioreactor (3), where the CO 2 Immobilization by photosynthesis of algae contained in the photobioreactor (3). The anae...
