Wastewater is introduced into the regulating tank 1 through the wastewater inlet pipe 7, and is physically initially filtered through the coarse grid filter 9. The reclaimed water after ozone disinfection treatment in the clarification tank 5 is discharged through the wastewater outlet pipe 8.

[0051] The working principle of the present invention is as follows: wastewater is introduced into the regulating tank 1 through the wastewater inlet pipe 7, and first undergoes physical coarse filtration through the coarse grid filter 9. Then, acidic solution is added to the regulating tank 1 through the acidic solution inlet pipe 101 to adjust the wastewater to an appropriate pH. Then, the wastewater enters the primary sedimentation tank 2 to react with the coagulant and undergo a primary chemical flocculation. Then, the water body enters the microbial flocculation reaction tank 3 to react with the microbial liquid and purify the water body through a biological treatment method. Then, the wastewater enters the secondary sedimentation tank 4 to react with the flocculation decolorizing agent and undergo a secondary chemical flocculation. By adding a microbial flocculation reaction tank 3 between the primary sedimentation tank 2 and the secondary sedimentation tank 4, a biological treatment method is introduced and combined with traditional physical and chemical methods, thereby giving full play to the advantages of various treatment methods and removing pollutants to the greatest extent. Finally, ozone can be introduced through the clarification tank 5 for oxidative disinfection treatment.
