Abstract: The reactor comprises a reactor container (12) with a flat or round base, a supply line (14) arranged in lower area of the reactor container for supplying wastewater to be cleaned into the reactor, a discharge line (16) for discharging cleaned water from the reactor, a solid material removing line (18) arranged in the lower area of the reactor container for removing solid material from the reactor, and a deflector means (32) arranged in the lower area of the reactor container. The deflector means has a diagonally running part. The reactor comprises a reactor container (12) with a flat or round base, a supply line (14) arranged in lower area of the reactor container for supplying wastewater to be cleaned into the reactor, a discharge line (16) for discharging cleaned water from the reactor, a solid material removing line (18) arranged in the lower area of the reactor container for removing solid material from the reactor, and a deflector means (32) arranged in the lower area of the reactor container. The deflector means has a diagonally running part and is arranged in such a way that the sinking solid material is diverted in the reactor from the upper reactor area towards bottom, is sedimented in the area of the solid material removing line and is discharged over the solid material removing line from the reactor. The deflector means is a deflector plate, which has a slop of 35-50[deg] related to the horizontals. The deflector plate is arranged to the middle of the reactor by reactor external wall towards bottom and is arranged so that the wastewater present in the reactor is re-supplied. Two deflector plates are arranged in the lower area of the reactor container and extend itself from the area of the middle of the reactor in the direction to the reactor external wall, where both deflector plates end with an interval to the reactor external wall. The four deflector plates are spaced apart from each other in the area of the middle of the reactor so that a groove-shaped column is formed between the deflector plates. The solid material removing line flows in the area of the column. In the lower area of the reactor container, four deflector plates are arranged, which extend itself from the area of the middle of the reactor in the direction to the reactor external wall, where two of the four deflector plates are connected over its side surface so that the four deflector plates are arranged in the form of a truncated pyramid. The four deflector plates end with an interval to the reactor external wall and are spaced apart from each other in the area of the middle of the reactor, where a rectangular, quadratic, oval or circular opening is formed between the deflector plates. The solid material removing line flows in the area of the opening. A deflector element is arranged in the lower area of the reactor container and a hollow truncated cone is reversed from the reactor base. The external edge of the hollow truncated cone is spaced apart from the reactor external wall. The four deflector plates or hollow truncated cone are filled in the sum of 70-90% of the reactor cross-section. The solid material removing line flows in the area of the opening equipped to the cover area of the hollow truncated cone. Bulk material arranged on the reactor base is arranged in the form of a negative cone. The solid material removing line is equipped in the area of the tip of the negative cone of the solid materials. A separation wall extending vertically towards top is arranged on the reactor base in the area of the middle of the reactor and the solid material is provided between both side surfaces of the separation wall and the reactor external wall as deflector means. The solid material is arranged in the form of a negative cone. Two solid material removing lines are provided from which one of the both negative cones of the solid material flows respectively in the area of the tip. The solid material is sediment, which sediments during operation of the reactor from the wastewater to be cleaned. An independent claim is included for a method for anaerobic cleaning of wastewater.
