NOVELTY - A water body in-situ purifying floating bed structure, solves the ecological floating island standard is not uniform, cannot be mechanically managed, plant withered period cannot be carried out water treatment, bad stability and so on, the solution is as follows: comprising a suspended bed fixing part, a suspended bed part and a water purifying unit. The water purifying unit includes: an open rectangular body outer bracket, a steel mesh, a modified sponge graphene a plant planting cage, the steel mesh is covered on the rectangular outer bracket, graphene modified sponge plate is fixed on the three vertical surfaces and the bottom surface of the steel mesh, the plant planting cage is provided with a group and uniformly distributed in the same direction and fixed in the outer bracket of the rectangular body. the plant planting cage is planted with aquatic plant or aquatic vegetable, the outer bracket of the rectangular body is provided with fish. Beneficial effect, the utility model proves that each 0.2 cubic meter water purifying unit can process 1 cubic meter flow; Major Pollutant: CODcr5 removal rate is more than 75 %, SS removal rate is more than 85 %, TN removal rate is more than 75 %, Tp removal rate is more than 75 %, NH3-N removal rate is more than 75 %.
