An exhaust-gas treatment module for an exhaust system of an internal combustion engine, comprising, following one another in an exhaust-gas flow direction: - a first mixing path with a first reactant dispensing arrangement in an upstream end region of the first mixing path and with a first mixing channel which is elongate in the direction of a first mixing path longitudinal axis (M 1), - a first exhaust-gas treatment arrangement which is elongate in the direction of a first exhaust-gas treatment arrangement longitudinal axis (A 1) comprising at least one SCR catalytic converter arrangement, with an upstream end region connected to a downstream end region of the first mixing path, - a second mixing path with a second reactant dispensing arrangement in an upstream end region, which is connected to a downstream end region of the first exhaust-gas treatment arrangement, of the second mixing path and with a second mixing channel which is elongate in the direction of a second mixing path longitudinal axis (M 2), - a second exhaust-gas treatment arrangement which is elongate in the direction of a second exhaust-gas treatment arrangement longitudinal axis (A 2) comprising at least one SCR catalytic converter arrangement, with an upstream end region connected to a downstream end region of the second mixing path and which has a downstream end region which is open for the release of exhaust gas and/or reactant, characterized in that the first mixing path, the first exhaust-gas treatment arrangement, the second mixing path and the second exhaust-gas treatment arrangement overlap one another at least in certain regions in the direction of the exhaust-gas treatment module longitudinal axis, wherein the first reactant dispensing arrangement and the second reactant dispensing arrangement are arranged substantially in the same axial end region of the exhaust-gas treatment module with respect to the exhaust-gas treatment module longitudinal axis, and in that the first mixing path, the first exhaust-gas treatment arrangement, the second mixing path and the second exhaust-gas treatment arrangement are arranged so as to follow one another around an exhaust-gas treatment module longitudinal axis, such that the first mixing path and the second mixing path are situated substantially diametrically opposite one another with respect to the exhaust-gas treatment module longitudinal axis and the first exhaust-gas treatment arrangement and the second exhaust-gas treatment arrangement are situated substantially diametrically opposite one another with respect to the exhaust-gas treatment module longitudinal axis. -
