The invention provides a tidal river sewage treatment and aquiculture integrated system which comprises aquaticplant floating blanket zones and a freshwater mussel culture zone arranged in the tidal river, wherein the freshwater mussel culture zone is arranged in the middle of the tidal river; and the aquaticplant floating blanket zones are arranged at two sides of the freshwater mussel culture zone. The aquaticplant floating blanket zones are divided into an emergent aquatic plant zone, a floating plant zone and a submerged plant zone according to the decontamination capability. Since emergent aquatic plants, floating plants and submerged plants are sequentially cultured in a riverway disclosed by the invention, the riverway is progressively purified layer by layer. In addition, different aquaticplants are subjected to reasonable companion planting and have purification capability all year round. The mussels in the freshwater mussel culture zone in the invention not only can be used for filtering phytoplankt
