摘要：The invention relates to a method and apparatus for producing a feed mixture, advantageously suitable to an anaerobic bioreactor and containing liquid and solid materials, for the further treatment of waste materials. The method of the invention includes at least the following steps:
a) into a feed mixture reactor (1), there is first fed liquid so that the free liquid surface
(5) is located essentially above the solid material feed point (6) provided in the reactor
(1),
reactor technology
b) the solid waste material fed into the feed mixture reactor (1) is fed to below the free liquid surface (5) of the reactor (1), and from the solid waste material there is separated (10, 14) both light and heavy rejectable materials by utilizing an agitator (7) installed in the feed mixture reactor (1), and countercurrent washing (14) directed towards the bottom part of the reactor (1). In the apparatus of the invention, the feed points (2, 17) of the liquid and sludgy waste materials to be fed into the feed mixture reactor are arranged on a lower level with respect to the agitator (7), and the feed point (6) of the solid waste material to be fed into the feed mixture reactor is arranged on a
higher level than the agitator (7).
