A plurality of porous tubes and impermeable layers interface with the collection sump 42. The porous pipe and the impermeable layer are provided with downward slopes along the direction of the collecting tank, so that the collected sewage can flow into the collecting tank conveniently. The impermeable layer can be made of a material with good sealing performance such as asphalt, cement or polyethylene sheets, or a natural material with small permeability coefficient such as clay.

As shown in fig. 2, the spraying module 50 includes a handle 51 and an agitation portion, the moving module is connected to the handle of the spraying module, a spraying opening is disposed on the handle of the spraying module, the spraying opening is located at a position of the handle 51 near the agitation portion, the agitation portion and the spraying opening of the spraying module are submerged in the upper purification bed 36, and a distance of the agitation portion submerged in the upper purification bed is preferably more than 15 cm.

The tip end part is used for stirring the fine sand on the lower layer, and the stirring rod is used for stirring the fine sand on the periphery, so that the fine sand is kept in a loose state and is prevented from being blocked by fine particles in sewage. And the movable sewage spraying device can spray sewage into the upper purifying bed more uniformly.

The interior of the tip portion of the spray module in this embodiment includes a waste cavity 24. The waste cavity is used for receiving larger and heavier particles in the sewage entering the spraying module, which cannot be discharged out of the spraying opening.

In operation of the apparatus, sewage is pumped through the conduit into the handle 51 of the spray module, where large particles settle into the waste cavity 24. The sewage is sprayed out by a spraying opening positioned below the handle part, and the sprayed sewage is absorbed by the upper purifying bed without contacting with air. The tractor drives the spraying module to move in the upper purification bed, so that the stirring part of the spraying module embedded in the upper purification bed continuously moves in the upper purification bed to separate the fine sand blocked by fine particles in sewage, thereby keeping the looseness of the fine sand in the upper purification bed and keeping the filtering activity of the upper purification bed.
