[0035] Example 2

[0036] A method of sewage treatment system for sewage treatment:

[0037] Pass the sewage through the coarse grid 1, the collection tank 2, the fine grid 3, the cyclone grit chamber 4, the adjustment tank 5, the coagulation sedimentation tank 6, the air flotation equipment 7, the intermediate tank 8 and the ultrafiltration equipment 9, and pass Coarse grid 1 removes large floating debris, fine grid 3 removes fine floating debris, cyclone grit tank 4 removes silt, coagulation sedimentation tank 6 removes suspended solid particles, and air flotation equipment 7 removes suspended solids in sewage Substances and colloids, and the ultrafiltration equipment 9 divides the sewage into clean water and concentrated water. The clean water is introduced into the disinfection tank 15. The concentrated water passes through the concentrated water adjustment tank 10, multi-stage coagulation sedimentation 11, A2O biochemical tank 12, and inclined tube sedimentation tank. 13. F...

Abstract

The invention provides a system and a method for treating sewage. The system comprises a thick grid, a water collecting tank, a fine grid, a rotational flow sand settling tank, a regulating tank, an emergency tank, a coagulation sedimentation tank, gas flotation equipment, an intermediate water tank, ultra-filtration equipment, a concentrated water regulating tank, a multistage coagulation sediment, an A2O biochemical tank, an inclined-tube sedimentation tank, a fiber turntable filter tank, a sludge concentrated water tank, a sludge dewatering room, a disinfection tank and a water recycling tank. The system and the method have the advantages that diversified processes for treating the sewage are combined with one another to form the complete system for treating the sewage, accordingly, different stages of sewage can be assuredly effectively treated, and treatment effects can be improved; outlet water treated by the aid of the system is high in quality, requirements of national emission indexes can be met, the outlet water can be applied to life again, and accordingly water resources can be reused.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment system and a sewage treatment method thereof. Background technique [0002] my country's current economy has entered the primary stage of developed countries, and many urbanization and industrialization constructions are constantly developing, and the environmental problems caused by rapid development are gradually revealed and dealt with, and are becoming increasingly severe. How to carry out scientific and effective environmental protection measures is the key issue of current economic development. In the process of environmental protection, the discharged sewage is also an environmental problem that needs to be solved urgently. [0003] Patent Publication No. CN104609660A discloses a sewage treatment method with high efficiency, energy saving, consumption reduction and resource recovery. into the return sludge, the effluent enters the sedimentation tank for...
