Refer to Fig. 1 and Fig. 2, country sewage integrated treatment unit 100 described in the utility model, be used for The sewage of rural area discharge is processed so that effluent quality meets discharge standard.This device includes anoxic pond 10, MBR film reaction pond 20 (MBR is the abbreviation of Membrane Bio-Reactor, membrane bioreactor), Self priming pump 30, ultra violet sterilizer 40, clear water reserviors 50 and sludge-tank 60, the outlet of anoxic pond 10 with The water inlet connection in MBR film reaction pond 20, a return duct is passed through by lower position in MBR film reaction 20 pond Connecting by lower position with anoxic pond 10, the outlet in MBR film reaction pond 20 connects with self priming pump 30, The outlet of self priming pump 30 connects with ultra violet sterilizer 40, and ultra violet sterilizer 40 is with clear water reserviors 50 even Logical, the mud mouth in MBR film reaction pond 20 is connected with sludge-tank 60, anoxic pond 10 by a sludge pump respectively； Anoxic pond 10 is connected with an Intermittent Aeration System 12, MBR film reaction pond 20 and a blast aeration system 21 Connect.Anoxic pond has chemical agent and adds mouth.

The method utilizing above-mentioned country sewage integrated treatment unit 100 to process sewage, comprises the steps:

S1, provide sewage integrated treatment device, comprising: anoxic pond 10, MBR film reaction pond 20, Self priming pump 30, ultra violet sterilizer 40, clear water reserviors 50 and sludge-tank 60, the outlet of anoxic pond 10 with The water inlet connection in MBR film reaction pond 20, a return duct is passed through by lower position in MBR film reaction pond 20 Connect by lower position with anoxic pond 10, so that the mixed-liquor return in MBR film reaction pond 20 is to anoxic pond In 10；The outlet in MBR film reaction pond 20 connects with self priming pump 30, and the outlet of self priming pump 30 is with purple Outer decontaminating apparatus 40 connects, and ultra violet sterilizer 40 connects with clear water reserviors 50, MBR film reaction pond 20 Mud mouth is connected with sludge-tank 60, anoxic pond 10 by a sludge pump 22 respectively；Anoxic pond 10 and an interval Aerating system 12 connects, and MBR film reaction pond 20 is connected with a blast aeration system 21.Anoxic pond has Chemical agent adds mouth.

S2, sewage enter in anoxic pond 10, enter under the intermittent aerating stirring condition of Intermittent Aeration System 12 Row hydrolysis acidification processes, the organic impurities in degraded sewage, after testing, and organic impurities degraded in this step 17%-25%.Add mouth by the chemical agent of anoxic pond 10 simultaneously and add chemical cooperated in anoxic pond 10 Dephosphorization reagent, removes the phosphorus in sewage；Anoxic pond 10 also receives the mixed liquor of MBR film reaction pond 20 backflow, Carry out denitrification process.

S3, through anoxic pond 10 process after sewage enter MBR film reaction pond 20, pass through blast aeration system 21 continuous aerations, carry out aerobic biochemical reaction, remove the organic impurities in sewage further；MBR film reaction The mixed liquor part in pond 20 is back in anoxic pond 10, carries out anti-nitre in the lump with the sewage in anoxic pond 10 Change processes；The mud part that MBR film reaction pond 20 produces is back to anoxic pond 10 by sludge pump 22, Supplementing microorganism for anoxic pond, another part is back to sludge-tank 60 by sludge pump 22.

S4, through MBR film reaction pond 20 process after sewage enter self priming pump 30, self priming pump 30 negative pressure is taken out Inspiration row solid-liquid separation, forms supernatant and mud, and mud is periodically got rid of.

The supernatant that S5, self priming pump 30 are formed after processing carries out disinfection in entering ultra violet sterilizer 40, disappears Poison enters clear water reserviors 50 after completing.Water in clear water reserviors 50 has been the water after processing, and detects it, Phosphorus concentration is less than 0.5mg/L.

Mud in S6, sludge-tank 60 carries out aerobic sigestion process, and the supernatant of generation is back to anoxic pond 10 Circular treatment, the mud of generation is periodically transported outward.

Country sewage after using these apparatus and method to process, material composition therein such as following table.

As can be seen from the above table, stable effluent quality reaches discharge standard after treatment.

Embodiment described above only have expressed several embodiments of the present utility model, its describe more concrete and In detail, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, For the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to Making some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, this utility model The protection domain of patent should be as the criterion with claims.
