The vertical baffle can block the water body from flowing so as to precipitate suspended matters in the water body and ensure the water outlet effect. The whole device realizes integrated design, is convenient to use and is simple and convenient to maintain.
The shell is in a hollow cylindrical shape, and the bottom of the shell is provided with a necking section with an inward inclined side wall. The shell bottom neck-in, the inclined plane of leanin is formed to the outer wall, is favorable to collecting the mud of sediment, is convenient for clear up.
The top of the shell is provided with a protective net, and the emergent aquatic plants penetrate through the protective net. The protection net prevents personnel from accidentally falling into the inner container, and reduces potential safety hazards in use.
The utility model has the advantages that: adopt the integrated structure, utilize plant roots to hang the membrane and form the zoogloea, carry out purification treatment to the water, whole area is little, and it is convenient to use the maintenance.

Detailed Description
Example (b):
referring to fig. 1-2, a plant root system biofilm culturing micro-polluted water treatment device is arranged below the ground 1 and comprises a hollow carbon steel shell 2, a glass steel inner container 3 and emergent aquatic plants 8, wherein a water inlet pipe 4 and a water outlet pipe 5 are respectively arranged on two opposite sides of the shell 2, a grid plate 6 is arranged in the middle of the inner container 4, a suspension filler ball layer 7 is arranged on the grid plate 6, the root system of the emergent aquatic plants 8 is positioned in the suspension filler ball layer 7, a communicating pipe 9 communicated with the inner cavity of the shell 2 is arranged on the inner container 3, an aeration device 10 is arranged at the bottom of the inner container 3, a vertical baffle 11 with the height not larger than that of the water outlet pipe 5 is arranged between the outer wall of the inner container 3 on one side of the water outlet pipe 5 and the inner wall of the shell 2, and a cavity between the shell.
