For reference, the cover 30 is omitted in FIG. 5 for convenience of description.

As shown in these figures, the sewage introduced from the bank 40 is introduced into the settlement 42. The settling paper 42 serves to filter out plastic stones floating on the water due to the small specific gravity, such as stones, sand, etc. that sink in the water in the sewage treatment process. Sewage discharged from homes and factories is very dirty, so if you send it to the rivers as it is, it can cause serious water pollution. Therefore, the living sewage is necessarily subjected to a sewage treatment process, the settlement 42 is made for the primary physical treatment of sewage, sewage. The settling paper 42 is usually provided with a mesh filter to filter the suspended matter, precipitates and the like first.

The sewage purified by the prefabricated artificial wetland blocks 10 and 20 via the settling pond 42 is discharged to the river through the discharge port 52 formed in the bridge 50.

Hereinafter, with reference to Figures 4 and 5 will be described in detail the process of purification of sewage by the natural purification system according to the present invention.

When sewage, which is a nonpoint source, flows into the settlement 42 from the bank 40 side, the settlement 42 primarily filters suspended matter and sediment using a mesh filter or the like. In other words, it primarily filters small specific gravity plastic bottles, large specific gravity stones and sand.

As such, the sewage that has passed through the settlement 42 passes through the first and second blocks 10 and 20 alternately. The sewage flows while being filtered by the filter medium filled in the blocks 10 and 20 while passing through the first and second blocks 10 and 20.

First, the sewage passes through the second communication portion 28 of the second block 20. Since the second communication portion 28 is located below the central plate 26, the sewage passing through the second communication portion 28 is filled from below. When the sewage that has passed through the second communication portion 28 is filled up to the height of the first communication portion 18 located next, the sewage passes through the second communication portion 28. In addition, the sewage passing through the second communication portion 28 passes through the second communication portion 28 located below. As a result, the sewage is filtered by the filter medium while passing through the first and second communication portions 18 and 28 of the first and second blocks 10 and 20 alternately assembled.

Referring to FIG. 4, the sewage passes through the first communication unit 18 and the second communication unit 28 alternately, so that the flow alternately occurs in the vertical direction as indicated by the arrow. In addition, referring to FIG. 5, the sewage flows alternately in left and right directions as indicated by arrows. As a result, the sewage continuously passes through the first communication portion 18 and the second communication portion 28 positioned in the diagonal direction, and the flow thereof changes not only in the vertical direction but also in the left and right directions. The sewage flowing through such a change shows an improved purification ability by the filter medium.

The sewage that has passed through the first and second blocks 10 and 20 is discharged into the natural stream through the outlet 52 formed in the bridge 50.

According to the natural purification system using the prefabricated wetland block described above, a comprehensive treatment process such as sedimentation, filtration, adsorption, microbial decomposition, and capture by plants is carried out, resulting in various deposits, nutrients, oils, bacteria, and metals. Contaminants can be removed. In addition, by improving the quality of the discharged rivers, there is an advantage in improving the value of water resources, creating a hydrophilic environment, and treating sewage treatment in rural and mountain villages, inflowing freshwater lakes, and nonpoint source treatment in upstream parts.
