The invention discloses a biological purification system for treating black and odorous water of a riverway, and belongs to the technical field of water treatment. The system comprises a filtering area, an odor removal treatment area, an anaerobic treatment area, an aerobic treatment area, a precipitation separation area and a power supply assembly, wherein biological purification boxes are arranged at the anaerobic treatment area and the aerobic treatment area in the direction perpendicular to water flow respectively; a plurality of purification cavities are formed in the biological purification boxes in the horizontal direction; and a plurality of biological filler frames with the radiuses sequentially increased from inside to outside are arranged in each purification cavity. According to the method, in-situ remediation is carried out on the black and odorous water of the riverway, the existing riverway can be fully utilized, and the construction land is greatly saved; by arranging the multiple biological f
