1, a natural purification wetland of a non-point pollution source in a rural area using a radical circulating agent is formed at one side and has an inlet 100a through which polluted water flows, A preprocessing unit 100 comprising a screen unit 110 of the screen unit 110 and a dip unit 120 which is embedded in the screen unit 110 to a predetermined size downwardly and has a step difference; The stainless steel mesh 211 having a predetermined size is formed at regular intervals in the other direction from the one side so as to sequentially pass the contaminated water pretreated in the pretreatment unit 100 and filled with the radical circulating agent 212, A radical oxidation sheet 200 in which a second Gabion 220 is formed by filling a gravel 210 and a stainless steel net 221 of a predetermined size with a crushed stone 222 and a ceramic for refractory 223; And a discharge pond 300 having a predetermined size through which purified water is discharged through the radical oxidized paper 200.

The pretreatment unit 100 removes contaminants from the polluted water flowing into the inlet port 100a and deposits the inorganic substances to the radical oxidized paper 200. The radical oxidized paper 200 decomposes organic substances by radical reaction, And adsorbs heavy metals, and releases purified water from the radical oxidized paper 200 to the discharge pond 300.

The pretreatment unit 100 is formed to have a predetermined size to receive and flow the contaminated water. The screen unit 110 is formed at a predetermined distance from the inlet 100a, And a lower surface of the lower surface of the screen unit 110 is lower than the lower surface of the screen unit 110 so that an inorganic material is precipitated.

The screen unit 110 may be formed of a screen of various known network types. In particular, the screen unit 110 may be formed of a wooden horseshoe at intervals of preferably 15 cm to remove contaminants contained in the contaminated water.

The sedimenting unit 120 is configured to sediment the inorganic substances contained in the polluted water that has passed through the screen unit 110 and is formed to have a step height lower than that before the screen unit 110 about the screen unit 110 A box of a predetermined size or a sewage manhole so that the inorganic material is precipitated in the settling portion 120 in the contaminated water from which the contaminants having passed through the screen portion 110 have been removed.

The radical oxidized paper 200 is formed to have a predetermined size so that the contaminated water pretreated in the pretreatment unit 100 can be received and flowed. The radical oxidized paper 200 is discharged at a predetermined interval in the other direction 1 Gabion 210 and a second Gabion 220 are formed.

The first Gabion 210 is formed by filling the inside of the stainless steel net 211 of a predetermined size with the radical circulating agent 212.

The stainless steel mesh 211 may be formed in various sizes, preferably 50 cm × 50 cm × 50 cm square, and filled with a radical circulating agent 212 to form the stainless steel mesh 211.

Particularly, a separate molded body 230 may be formed to fix the radical circulating agent 212, and the radical circulating agent 212 may be inserted into the molded body 230 to fix the molded body 230.

The formed body 230 is manufactured by molding, drying and firing a cylindrical body in which a through hole 231 is formed at the center by mixing zeolite, fillite, and inorganic binder at a predetermined ratio, and the inside of the through hole 231 is subjected to radical circulation So that the radical circulating agent 212 is prevented from being lost.

In this case, zeolite, filler, and inorganic binder constituting the formed body 230 may be mixed and molded into a predetermined shape. In particular, zeolite and phyllite may be mixed with an inorganic binder It is effective for adsorption of contaminants and odor removal by molding.

The zeolite is a mineral of tubular particles, which easily passes water molecules to remove floating matters, and is excellent in ion substitution ability and effectively removes inorganic nitrogen.

The fillite not only effectively removes odorous substances containing sulfur by mica-based minerals but also improves the turbidity and adsorbs heavy metals by increasing the zeta potential of colloidal inorganic particles causing turbidity and coagulating and sedimenting them with each other.

The formed body 230 is preferably formed by mixing zeolite, filler, and inorganic binder in a ratio of 50%: 40%: 10%, respectively.

In this way, the cylindrical molded body 230 penetrates the central portion to form the through hole 231, the radical circulating agent 212 is inserted therein, and the paraffin stopper (not shown) is inserted to prevent the radical circulating agent 212 from flowing out. The through hole 231 is closed.

At this time, the paraffin stopper is formed to be porous, so that the contaminated water passes through the perforations of the marinade stopper, flows into the through-hole 231, and passes through the radical circulating agent 212.

Preferably, the amount of the radical circulating agent 212 to be installed is determined to be 2 mg / L, and the organic matter is decomposed into carbon dioxide and water by radicals, as shown in Equation (1) ,

The second Gabion 220 is formed by filling a crushed stone 222 and a ceramics 223 for refractory inside of a stainless steel net 221 of a predetermined size for the purpose of removing phosphorus and adsorbing heavy metals.

The stainless steel net 221 may have various sizes, preferably 1 m × 1 m × 1 m.

The ceramics for impregnation 223 can be made of a variety of ceramics to remove phosphorus and adsorb heavy metals. In particular, it is possible to mix and purify raw wastewater sludge, zeolite and inorganic binder, So that it can be used.

Preferably, the dyeing wastewater sludge and the zeolite inorganic binder are mixed at a ratio of 70%: 20%: 10%, respectively, and molded into a cylindrical shape having a diameter of 70 mm and a height of 80 mm, It is to maximize the phosphorus adsorption by using hemmerite and zeolite contained about 10% aluminum.

In addition, the second Gabion 220 may be formed across the rear end of the radical gutters 200 and may be formed to have a height higher than the water depth, so that the upper part can be used as a passageway.

Phosphorus ion is easily insoluble in aluminum due to the catalytic action of free radical ion, and the dissolved phosphorus is removed as shown in Equation (4).
