The chemical reaction cylinder 1 and the filter cylinder 21 are rotatably connected. There is a shaft 4, which can be connected to the chemical reaction tube 1 and the filter tube 21 at the connection point through a sealed bearing. A motor pulley 5 driven by a motor is arranged on the shaft 4. In the present application, the motor pulley 5 can be connected to an external motor through a pulley to realize transmission connection, so that the shaft 4 can be driven to rotate, which is not shown in the figure. A stirring member 6 is fixedly connected to the outer surface of the shaft 4. The stirring member 6 can be a stirring sheet or a stirring rod. The stirring member 6 is located in the chemical reaction tube 1. A clean water discharge pipe 7 is fixedly connected to the filter tube 21. The clean water discharge pipe 7 can discharge construction wastewater that has been chemically and physically treated so as to reuse the water body.

[0026] At least three filter elements 8 are longitudinally arranged on the inner side of the filter cartridge 21. In the present application, the three filter elements 8 can be a coarse filter layer, a medium filter layer and a fine filter layer from top to bottom, so as to meet the multiple filtering effects of wastewater. Three guide covers 9 are fixedly connected to the inner wall of the filter cartridge 21. The guide covers 9 can provide a guide channel for the debris on the filter element 8. The guide covers 9 penetrate the filter element 8, and the filter element 8 is detachably connected to the guide covers 9. A sealing interval is formed between two adjacent guide covers 9. The setting of the sealing interval can prevent the passage of wastewater. The guide covers 9 at the bottom The bottom is fixedly connected to an outer discharge cover 91, which is fixedly passed through the filter cartridge 21.
