The sewage treatment system of claim 7, wherein if the modularized humic filler biofilter is arranged on the ground, a water inlet pump is arranged to lift the wastewater in the regulating tank into the water distribution layer; if the modularized humic filler biological filter is arranged underground, the waste water in the regulating tank flows into the water distribution layer through gravity.
9. The wastewater treatment system of claim 7 or 8, wherein the water outlet channel is filled with biochar ceramsite particle filler.
10. The sewage treatment method of the modularized humic filler biological filter is characterized by comprising the following steps of:
according to project site topography and climate conditions, determining that the modularized humic filler biological filter is installed on the ground or underground;
the domestic sewage is pretreated by a three-grid septic tank, enters an adjusting tank, and is homogenized with water quality and water quantity, then lifted by a water inlet pump or gravity automatically flows to a water distribution layer, and the water distribution layer distributes the sewage to the surface of a filter tank layer uniformly;
sewage sequentially flows through the tank modules of the filter layers by gravity, and pollutants are removed through physical adsorption of granular humic biological fillers and biochemical treatment of microorganisms;
the sewage treated by the filter layer sequentially enters a water collecting layer and a water outlet channel, and the removal of phosphorus is enhanced by biochar ceramsite particles in the water outlet channel, so that the sewage meets the discharge standard of the first grade A.
