The wastewater distributor includes a plurality of outlet openings and is moveable within the treatment tank and the traction mechanism is configured to move the wastewater distributor in a reversing manner between the first and second opposite edge regions of the treatment tank. The feed line is elastically deformable so as to allow a movement of the wastewater distributor in a direction of back and forth movement. ## Claims ### Claim at position 1 1-21. (canceled) ### Claim 22 An apparatus for treating wastewater comprising: a treatment tank having a first edge region and a second edge region opposite the first edge region; a feed line configured to provide the wastewater to the treatment tank; a movable wastewater distributor connected to an end of the feed line and configured to distribute the wastewater in the treatment tank, wherein the wastewater distributor includes a plurality of outlet openings and is moveable within the treatment tank; and a traction mechanism configured to move the wastewater distributor in a reversing manner between the first and second opposite edge regions of the treatment tank, wherein the feed line is elastically deformable so as to allow a movement of the wastewater distributor in a direction of back and forth movement. ### Claim 23 (depends on 22) The apparatus as recited in claim 22, wherein the wastewater distributor has a main extent substantially transverse to the direction of back and forth movement. ### Claim 24 (depends on 22) The apparatus as recited in claim 22, wherein the wastewater distributor includes an elongated pipe. ### Claim 25 (depends on 22) The apparatus as recited in claim 22, wherein the traction mechanism is operable in an endlessly circulating manner. ### Claim 26 (depends on 22) The apparatus as recited in claim 22, wherein the traction mechanism includes an electric motor drive. ### Claim 27 (depends on 22) The apparatus as recited in claim 22, wherein the traction mechanism includes a cable pull, a belt, a belt band and/or a chain. ### Claim 28 (depends on 22) The apparatus as recited in claim 22, further comprising a link chain disposed at the treatment tank configured to guide the feed line. ### Claim 29 (depends on 22) The apparatus as recited in claim 22, further comprising a multi-joint arm disposed at the treatment tank configured to guide the feed line. ### Claim 30 (depends on 22) The apparatus as recited in claim 22, wherein the feed line includes a corrugated hose. ### Claim 31 (depends on 22) The apparatus as recited in claim 22, wherein the feed line is free from lateral guides. ### Claim 32 (depends on 22) The apparatus as recited in claim 22, wherein the wastewater distributor has adjustable buoyancy. ### Claim 33 (depends on 22) The apparatus as recited in claim 22, wherein the wastewater distributor has a downforce receptacle. ### Claim 34 (depends on 22) The apparatus as recited in claim 22, wherein at least one of the plurality of outlet openings is inclined relative to the horizontal. ### Claim 35 (depends on 22) The apparatus as recited in claim 22, wherein the wastewater distributor includes at least one sensor configured to detect at least one parameter of the wastewater. ### Claim 36 (depends on 22) The apparatus as recited in claim 22, wherein the wastewater distributor has an outer contour promoting a mixing of the wastewater being fed into the treatment tank with a wastewater already present in the treatment tank. ### Claim 37 (depends on 22) The apparatus as recited in claim 22, wherein he feed line is disposed on a bottom of the treatment tank parallel to the direction of back and forth movement of the wastewater distributor. ### Claim 38 (depends on 22) The apparatus as recited in claim 22, wherein the feed line is guided transversely to a side edge of the treatment tank relative to the direction of back and forth movement. ### Claim 39 (depends on 38) The apparatus as recited in claim 38, further comprising a wastewater feed and a conveying unit operatively connected to the feed line, the feed line feeding the wastewater from the wastewater feed. ### Claim 40 (depends on 39) The apparatus as recited in claim 39, wherein the conveying unit is movable synchronously with the wastewater distributor. ### Claim 41 (depends on 22) The apparatus as recited in claim 22, wherein the wastewater distributor is annularly closed. ### Claim 42 A wastewater treatment plant for treating wastewater and sludge, comprising: a treatment tank having a first edge region and a second edge region opposite the first edge region; a feed line configured to provide the wastewater; a movable wastewater distributor connected to an end of the feed line and configured to distribute the wastewater in the treatment tank, wherein the wastewater distributor includes a plurality of outlet openings and is moveable within the treatment tank; a traction mechanism configured to move the wastewater distributor in a reversing manner between the first and second opposite edge regions of the treatment tank, wherein the feed line is elastically deformable so as to allow a movement of the wastewater distributor in a direction of back and forth movement; and a gas collector disposed above the a treatment tank and configured to trap gases emanating from the treatment tank.
