The left part of the filter chamber is a coarse filter chamber 5, and the right part is a fine filter chamber 6. The coarse filter chamber 5 is sealed and rotatably connected to the fine filter chamber 6. The inner wall of the coarse filter chamber 5 is fixedly connected to a guide mesh frame 51. The inner wall of the coarse filter chamber 5 is connected to a coarse residue discharge structure. A plurality of concentrically arranged fine filter cartridges 67 are fixedly connected to the fine filter chamber 6. The side walls of the fine filter cartridges 67 are hollow.

[0033] The filter chamber is divided into a coarse filter section 2, a fine filter section 3, and an adsorption section 4 from left to right. The coarse filter section 2 is rotatably connected with a coarse filter chamber 5, the fine filter section 3 is rotatably connected with a fine filter chamber 6, and the adsorption section 4 is provided with an adsorption component 7. The landscape sewage enters the coarse filter chamber 5 after circulation. The coarse filter chamber 5 is a rotatable cylindrical structure. A guide mesh frame 51 with an annular array is fixed in the coarse filter chamber 5. The outer end of the guide mesh frame 51 is fixedly connected to a convergence tube 52.
