[0027] See also Figure 1-3 As shown, this embodiment is an artificial wetland treatment device, comprising:

[0028] Sand-water separation area, anaerobic area, floating bed area;

[0029] The sand-water separation area is used to separate sediment, and the anaerobic area and floating bed area use a variety of functional microorganisms to purify pollutants;

[0030] The sand-water separation area includes a sand hopper 11, a drive motor 13, a hollow cylindrical net 14, and an auger 15. The drive motor 13 is arranged directly above the sand hopper 11, and the hollow cylindrical net 14 is fixed to the lower part of the output end of the drive motor 13. The auger 15 is fixed to the outer surface of the hollow cylindrical net 14, and the outer diameter of the auger 15 gradually increases from bottom to top;

[0031] The sand hopper 11 serves as a carrier for sediment separation, and the driving motor 13 provides the force required for the rotation of the hollow cylindrical net 14. The hollow cylindrical net 14 separates the sediment to meet the requirements of transporting the sewage to the anaerobic zone, and the auger 15 is structurally installed to separate the sediment.

[0032] A bracket 18 is fixed to the outer edge of the upper end of the sand hopper 11, and a support 12 is fixed to the middle of the bracket 18, and a drive motor 13 runs through the middle of the support 12;

[0033] The bracket 18 is used to structurally mount the support 12, and the drive motor 13 is structurally mounted through the support 12;

[0034] An electromagnetic valve is provided at the lower end of the sand hopper 11, and a ring block 16 is fixed to the lower part of the outer surface of the sand hopper 11, and legs 17 are fixed to the outer surface of the ring block 16 at equal intervals;

[0035] The opening and closing of the electromagnetic valve facilitates the use before and after the separation of sediment. The ring block 16 fixes the support leg 17 and provides structural stability of the device through the contact between the lower end of the support leg 17 and the contact surface.

[0036] The anaerobic zone includes an anaerobic box 21; the floating bed zone includes a floating bed box 31;

[0037] The anaerobic chamber 21 and the floating bed chamber 31 provide the space required for various functional microorganisms to purify pollutants;

[0038] A first supporting layer 22 is provided at the bottom of the anaerobic box 21, and a first filler layer 23 is provided at the top of the anaerobic box 21;

[0039] The first supporting layer 22 supports the first filler layer 23, and the first filler layer 23 acts on the sewage to perform preliminary purification treatment;

[0040] A second supporting layer 32 is provided at the bottom of the floating bed box 31, and a second filler layer 33 is provided at the top of the floating bed box 31. A floating bed 34 is provided at the upper end of the second filler layer 33.

[0041] The second supporting layer 32 supports the second filler layer 33, and the second filler layer 33 cooperates with the floating bed 34 to purify the sewage again.

[0042] It also includes a guide portion, which includes a guide pipe 41, a water distribution pipe 42, a guide step 43, and a water outlet pipe 44;

[0043] The ends of the guide pipe 41 extend into the hollow cylindrical net 14 and the anaerobic box 21 respectively, and one end of the water distribution pipe 42 is threadedly connected to one end of the guide pipe 41. The guide step 43 is fixed to the upper part of one side of the anaerobic box 21, and the outlet pipe 44 passes through the lower part of one side of the floating bed box 31.

[0044] The guide pipe 41 guides the sewage after sediment separation into the anaerobic box 21, and the water distribution pipe 42 distributes the guided water. The guide step 43 can guide the sewage after preliminary purification into the floating bed box 31, thereby increasing the dissolved oxygen concentration in the water and creating an aerobic environment. The outlet pipe 44 discharges the purified sewage.

[0045] Working principle: After the sand hopper 11 is firmly placed by the support legs 17, mud and sand are put into the sand hopper 11 and sewage is transported into it;

[0046] After the sewage enters the sand-water separation zone, the controlled drive motor 13 drives the hollow cylindrical net 14 to rotate, and the linked auger 15 rotates. Under the action of the spiral rotation, the silt in the sewage is thrown to the pool wall of the sand-water separation zone and then slides into the sand hopper 11 to separate the silt. One end of the guide pipe 41 extends to the inside of the hollow cylindrical net 14, and the other end is connected to one end of the water distribution pipe 42. Under the action of the pump, the sewage after the silt is separated can be transported to the inside of the anaerobic box 21, and the organic matter is decomposed and converted and biological denitrification is carried out through the first supporting layer 22 and the first filler layer 23.

[0047] Next, the water flows through the lower opening on one side of the anaerobic box 21 to the guide step 43 and is transported into the floating bed box 31. The water passes through the second support layer 32, the second filler layer 33 and the floating bed 34 to further purify pollutants such as nitrogen, phosphorus and organic matter in the water. The purified water is then discharged through the outlet pipe 44.

[0048] This solution can achieve efficient removal of pollutants by multiple functional microorganisms while reducing the occupied space. It has strong applicability and can meet the needs of different uses.
