Abstract: The device for treating wastewater, comprises a container (2) flow throughable from the wastewater in which the wastewater flows through an inlet (5) in an operation of the container and flows off from the treated wastewater through an outlet (7), a deflecting arrangement, and bypass container, where a flow guide means is present with a partition wall (9), which pretends a flow of the wastewater in the container in such a way that a portion is separated from sink- and/or floating matters in the container carried along into the wastewater. The device for treating wastewater, comprises a container (2) flow throughable from the wastewater in which the wastewater flows through an inlet (5) in an operation of the container and flows off from the treated wastewater through an outlet (7), a deflecting arrangement, and bypass container, where a flow guide means is present with a partition wall (9), which pretends a flow of the wastewater in the container in such a way that a portion is separated from sink- and/or floating matters in the container carried along into the wastewater. The partition wall is formed so that the wastewater is guided that comes from the inlet in the operation of the container along the partition wall in direction of an area lying opposite to the inlet of the container, where the waste water flows through in a flow profile of a siphon device (14) and subsequently arrives in a post-treatment area separated to other areas of the container. The inlet and the outlet are displaced in a topview of the container by an angle area of 300 degrees. The deflecting arrangement is provided so that a redirecting of the wastewater is carried out at an end facing towards the inlet of the partition wall. The post-treatment area is integrated into the container so that the post-treatment area partially lies below a wastewater level in the operation of the container, where the flow of the wastewater predominates on an inner side of a wall of the post-treatment area and the wastewater is opposed for prevailing the flow of the wastewater on an outer side of the wall of the post-treatment area, which is formed in a groove-like manner, passes adjacent to the inner side of a container wall, is aligned so that flow paths of the wastewater constitute to the post-treatment area of the portion of a theoretical flow path of the wastewater in the container from the inlet to the outlet of a third of the flow path, and is developed so that a volume occupied from the wastewater in the operation of the container in the post-treatment area constitutes a small portion of a total recording volume for the wastewater. Two partition walls are partially present lying opposite in the operation of container into the wastewater in which an intermediate area flows from the inlet and a coarse cleaning of the wastewater occurs into the intermediate area. The partition wall of the container wall extends itself towards the area opposite to the inlet of the container, where the partition wall are partially immersed in the operation of the container in the wastewater that extends itself up to a concentric area of the container. The inlet and the outlet form itself on a same side of the container. The bypass container flows through from the wastewater is provided with a floating matter barrier by which an inflow quantity arrives in an inlet side that flows to the container through an inlet maximum and/or subsequently arrives itself during the inlet of the inlet side partially closed in the operation of the container arriving the wastewater in the area at the outlet, where a connection of the bypass container is formed at the container so that the floating matter retained into the bypass container having the floating matter barrier for the fall, flows into the container. An independent claim is included for light-liquid separator system for treating wastewater.
