They are widely used in the treatment of polluted water bodies because of their low operation and maintenance costs, good decontamination effects and landscape effects.

[0059] Working principle:

[0060] In the first step, the sewage is injected into the surface flow wetland device 3 through the sewage inlet pipe 1, and the sewage is initially filtered and purified in the process of flowing along the circular surface flow wetland device 3;

[0061] In the second step, the primary filtered sewage enters the automatic valve assembly 8 through the primary filter water inlet pipe 801, and the water quality detection device 802 detects the water quality of the primary filtered sewage flowing through the primary filter water inlet pipe 801. When the detection results of each detection sensor in the water quality detection device 802 are all within the qualified range, the driving gear mechanism 805 drives the electric slide mechanism 804 to open the first diverter valve 806, and the primary filtered sewage flows into the tertiary purification water storage tank 5 through the first diverter valve 806; when one or more of the detection results of each detection sensor in the water quality detection device 802 are unqualified, the driving gear mechanism 805 drives the electric slide mechanism 804 to open the second diverter valve 807, and the primary filtered sewage flows into the secondary purification device 4 through the second diverter valve 807;

[0062] In the third step, when the primary filtered sewage enters the secondary purification device 4, the functional material filter chamber 401 connected in series purifies the primary filtered sewage, and then it enters the series-connected reagent treatment chamber 402 in turn. According to the detection results of each detection sensor in the water quality detection device 802, the electric control box controls the corresponding reagent treatment chamber 402 to perform the reagent adding operation; after the reagent adding is completed, the water pump 1 403 is turned on to discharge the sewage in the four groups of reagent treatment chambers 402 to which the corresponding reagents have been added into the tertiary purification water storage tank 5; at the same time, the reagent box 4024 that releases the reagent completes the reagent replenishment under the joint action of the electromagnetic valve 3 4024e and the liquid level relay in the reagent box 4024;

[0063] In the fourth step, no matter the sewage is initially filtered by the surface flow wetland device 3 or is secondary filtered by the secondary purification device 4, after entering the tertiary purification reservoir 5, the anti-seepage layer, gravel layer, activated carbon layer, sand and gravel layer and soil layer laid in the tertiary purification reservoir 5 further purify the sewage; at the same time, the aerator is turned on to reduce the nitrite content and increase the dissolved oxygen content, thereby ensuring that the sewage can meet the discharge index;

[0064] In the fifth step, the drainage recovery device 6 in the tertiary purification water storage tank 5 filters the further purified sewage again through the seepage filter cartridge 601, and then discharges it through the second pump 602 and the purification drainage pipe 2;

[0065] In the sixth step, according to the growth of plants in the surface flow wetland device 3 and the tertiary purification water storage tank 5, the staff collects the fallen leaves of the plants or harvests the plants at regular intervals, and transmits and crushes them through the transmission belt device 604 and the crusher 605, and then puts them into the fermentation cylinder 603 through the pipeline. The plant fragments are driven by the stirring head 6072 to quickly enter the fermentation cylinder 603 and are compacted; then the sealing cover 6036 of the fermentation cylinder 603 is closed by the rotating motor to carry out fermentation;

[0066] In the seventh step, after the fermentation is completed, the fertilizer is shoveled into the conveying bucket 703 on the conveyor belt 702 in sequence through the pouring shovel mechanism 606. The rotating conveying bucket 703 is turned over under the action of the turning column 704, and the fertilizer is poured into the surface flow wetland device 3; then the staff will spread the fertilizer poured into the surface flow wetland device 3 to complete the nutrient supply to the plants in the surface flow wetland device 3.
