In this embodiment, the apparatus shown in FIG. 1 is used for rural sewage treatment, domestic sewage passing through a fine grid is used as influent water, and the amount of influent water is 0.042m 3 The water quality of inlet water is as follows: COD is 86.57-350.70 mg/L, ammonia nitrogen is 14.32-53.84 mg/L, TN is 20.52-58.32 mg/L, TP is 1.76-7.18 mg/L, SS is less than or equal to 220mg/L, and pH is 6-9.
In this embodiment, the first valve 104 is opened to allow about 30% of the influent wastewater to enter the anoxic zone 100 and about 70% of the influent wastewater to enter the anaerobic zone 200.
Firstly, domestic sewage enters an anoxic zone 100 from an anoxic zone water inlet pipe 101 for denitrification reaction, and dissolved oxygen is controlled to be 0.2-0.5 mg/L. About 70% of the sewage influent enters the anaerobic tank (200) through the anoxic zone beyond the pipe 103 and beyond the pipe outlet 201.
Further, the anoxic zone 100 effluent enters the anaerobic zone 200 through an anaerobic zone inlet pipe 202. The dissolved oxygen content in the anaerobic zone 200 is typically controlled below 0.2 mg/L. In the dephosphorization process, the biological dephosphorization function is mainly achieved. The biological phosphorus removal consists of two processes of phosphorus absorption and phosphorus release, and when phosphorus is released anaerobically, organic matters which can be quickly biodegraded along with solubility are stored in the bacteria so as to degrade COD, and the phosphorus is excessively absorbed by the phosphorus accumulation bacteria when the phosphorus accumulation bacteria enter an aerobic environment. The anaerobic zone 200 adopts a combined filler, specifically: the polypropylene porous rotary suspension ball is made of polypropylene material and has a diameter of 100mm, 3-5 Banhor efficient biological carriers and 1 piece of elliptic red brown common volcanic rock with a length of about 20-30mm and a width of about 50-60mm are placed in the suspension ball to maintain sufficient biomass in the upper area of the suspension ball.
Further, the effluent of the anaerobic zone 200 enters the aerobic zone 300 through an aerobic zone inlet pipe 301. The aerobic zone 300 adopts MBBR technology, filler is added, the filler is Banhor high-efficiency biological carrier (product is Banhor high-efficiency biological carrier) produced by Banhao corporation, and the adding amount of the filler is 5kg/m 3 . The process is a biological reaction in an activated sludge processThe suspended filler is added into the device, so that the advantages of an activated sludge method and a biofilm method are integrated, the defects of the two processes are avoided, and the synchronous biological nitrogen and phosphorus removal effect is achieved; the dissolved oxygen content in the aerobic zone 300 is generally controlled to be above 2.0 mg/L.
Further, an aerobic zone air inlet pipe 304 is arranged in the aerobic zone 300, and an electromagnetic blower (with power of 39W) enters the aerobic zone air inlet pipe 304 through an aerobic zone air inlet 302 and is conveyed to a microporous aeration disc 305 at the bottom of the aerobic zone 300, so that high-efficiency aeration is realized. The aerobic zone inlet pipe 304 is fixedly connected with the microporous aeration disc 305 through an aeration disc fixing connector 307.
Further, the effluent from the aerobic zone 300 flows into the bottom of the settling zone 400 through a settling zone inlet pipe 406 for solid-liquid separation. In settling zone 400, an electromagnetic blower (power 39W) is used to power the return flow of mixed liquor in mixed liquor riser 408 from settling zone air inlet 403 through settling zone gas lift tube 407, and the electromagnetic blower is used to provide air to aerobic zone 300; after the mixed liquor at the bottom of the settling zone 400 passes through the mixed liquor riser 408, a part of the mixed liquor flows back to the anoxic tank 100 through the mixed liquor return pipe 401 and the anoxic zone return pipe 102 to promote denitrification reaction; the other part of the mixture flows back to the aerobic zone 300 through a mixed liquor return pipe 401 and an aerobic zone return pipe 303 to supplement the active microorganism amount.
Further, the effluent in the settling zone 400 enters the clean water zone 500 through the clean water inlet pipe 405 from the clean water inlet 404, and the water in the clean water zone 500 is discharged from the clean water outlet 502 through the clean water outlet pipe 501.
