The domestic sewage enters an anaerobic reaction zone 10 from a water inlet 11 through a basket 12 filter screen of a filtering-anaerobic reaction zone, and then enters an aerobic-biological removal zone from a water passing port 13 arranged at the opposite angle; under the aeration action of the aeration pipe, the sewage is adsorbed and degraded by microorganisms in the internal floating type filler 24, activated sludge in water and plants; and then the sewage enters the detachable filtering area through the sawtooth-shaped overflow port, passes through the filter cloth, enters the bottom water outlet area 32 through a water outlet 35 arranged at the upper end of the bottom of the detachable filtering frame 31 and a cylindrical drain pipe 36 arranged at the bottom end, and is discharged after reaching the standard through a water outlet 37.
Part of the sludge enters the sludge conveying pipe 51 and realizes the partial return of the sludge under the action of the gas conveying pipe 43.
After the running time is 30 days, the COD concentration of the effluent quality is 40.26mg/L, the ammonia nitrogen concentration is 3.47mg/L, and the total phosphorus concentration is 0.31mg/L, which all meet the first-class A requirement.
It should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
