Embodiment 1

[0032] A sewage treatment system such as figure 1 , figure 2 , image 3 As shown, it includes coarse grid 1, water collecting tank 2, fine grid 3, cyclone grit chamber 4, regulating tank 5, coagulation sedimentation tank 6, air flotation equipment 7, intermediate pool 8, ultrafiltration equipment 9, concentration Water conditioning tank 10, multi-stage coagulation sedimentation 11, A2O biochemical tank 12, inclined tube sedimentation tank 13, fiber turntable filter tank 14, disinfection tank 15, reuse water tank 16, sludge concentrated water tank 17, sludge dehydration room 18, Emergency pool 19, acid adjustment area 20, first-level PH adjustment area 21, first-level coagulation and sedimentation area 22, second-level PH adjustment area 23, second-level coagulation and sedimentation area 24, third-level PH adjustment area 25, third-level coagulation Sedimentation zone 26, pH adjustment zone 27, biochemical zone 28 and secondary sedimentation zone 29, the method for its sewa...

Embodiment 2

[0036] A method for treating sewage in a sewage treatment system:

[0037] The sewage passes through the coarse grid 1, the sump 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 pool 8 and the ultrafiltration equipment 9, and passes through The coarse grid 1 removes larger floating debris, the fine grid 3 removes fine floating debris, the cyclone grit chamber 4 removes sediment, the coagulation sedimentation tank 6 removes suspended solid particles, and the air flotation device 7 removes suspended solids in sewage Substances and colloids, while the ultrafiltration equipment 9 divides the sewage into clear water and concentrated water. The clear water is introduced into the disinfection tank 15, and the concentrated water passes through the concentrated water adjustment tank 10, multi-stage coagulation sedimentation 11, A2O biochemical tank 12, and inclined tube sedim...

Embodiment 3

[0040] A method for treating sewage in a sewage treatment system:

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...
