Description

Technical Field

[0001] The present invention relates to the technical field related to artificial wetlands, and in particular to a composite artificial wetland. Background Art

[0002] Constructed wetlands are artificially constructed and controlled land similar to swamps. Sewage and sludge are distributed in a controlled manner on artificially constructed wetlands. During the flow of sewage and sludge in a certain direction, the sewage and sludge are treated by the synergistic effects of soil, artificial media, plants, and microorganisms, which mainly utilize the physical, chemical, and biological effects of soil, artificial media, plants, and microorganisms. Its mechanism of action includes adsorption, retention, filtration, oxidation-reduction, precipitation, microbial decomposition, transformation, plant shading, residue accumulation, transpiration water and nutrient absorption, and the effects of various animals.

It discloses a constructed wetland sewage treatment system that prevents clogging. It consists of three parts with a simple overall structure. The preliminary treatment of the sewage to be treated is completed by setting up a magnetic coagulation reactor and an inclined tube sedimentation, and then further purification is carried out through an artificial wetland to achieve the final treatment of the sewage to be treated. At the same time, it also realizes a high degree of concentration of system functionality. By setting up three matrix sections with gradually decreasing particle sizes in the artificial wetland, and the three matrix sections use different materials as matrices, sufficient filtration, adsorption and retention of impurities in the sewage to be treated can be achieved.

[0004] However, the above patent still has some shortcomings. The above artificial wetland can reduce the probability of blockage, but it needs to use a magnetic coagulation reactor, an inclined tube sedimentation tank and a magnetic recovery device, which increases the cost of the artificial wetland, and the filler will continue to adsorb impurities. Although the sewage is initially purified, it only prolongs the time required for the filler to be blocked. However, the problem of filler blockage still exists.

[0039] When blockage occurs inside the stuffing box, the corresponding stuffing unit can be taken out from the wetland pool 1, and then the box cover 4 and the filter plate 6 can be removed to clean or replace the stuffing 5. Removing the filter plate 6 also facilitates cleaning of the filter plate 6, and the structure of the stuffing unit facilitates subsequent maintenance and cleaning; after removing the filter plate 6 from the stuffing box, it can also be replaced with a filter plate 6 with a different filter aperture.

[0040] In a preferred embodiment of the invention, a stepped groove 7 is formed at the open portion of the wetland pool 1, and limit blocks 8 located in the stepped groove 7 are provided at the ends of the two side walls of the stuffing box away from the filter plate 6, and horizontal bar grooves are protruding from the side walls of the stepped groove 7, one of the limit blocks 8 is detachably connected to two limit strips 10 that can be inserted into the bar grooves through a plurality of connecting bolts 9, and the bottom of the limit strip 10 is in contact with the upper surfaces of the corresponding plurality of limit blocks 8.
