A centrifuge guides layered discharged water into the A / O soil percolation system; the A / O soil percolation system comprises an anaerobic soil percolation area and an aerobic soil percolation area, respectively; and water discharged from the centrifuge is guided into the bottom in the anaerobic soil percolation area by a water inlet pipe; water discharged from the A / O soil percolation systems is sprayed into a surface turbulent flow screening and filtering device, so that viruses and heavy metals in the water are removed, and organic matters are mineralized or decomposed; then the water enters a rotary sand removal device to carry out sand removal, and finally clean water reaching the standard is discharged. According to the invention, an A / O process is used in a soil percolation system, and the soil percolation system is improved by using the A / O process and an alternate vertical flow concept, so that the cost and expense of deep treatment of sewage are reduced, the production of secondary pollution in the treatment process is avoided, and the effluent water quality of sewage is enhanced.
