Problems solved by technology
[0004] This inclined-bottom subsurface flow artificial wetland combined system, when purifying sewage, there are always solid pollutants such as insoluble waste residue, soil, plastic, etc. in the sewage. The above-mentioned system makes these solid pollutants accumulate in the aeration tank unit, After long-term accumulation, the solid waste will occupy the space of the aeration tank unit, affecting the normal operation of the aeration device, and even making the aeration device unable to work

Embodiment
[0035] Example: Reference figure 1 and figure 2 , an inclined-bottom subsurface flow constructed wetland combination system, including a settling tank 10, an aeration tank 11, a biochemical tank 12, and a degradation tank 13 connected in sequence. The settling tank 10 is used for solid-liquid separation, so that solids are deposited in the settling tank 10 At the bottom, the filtered sewage is oxygenated through the aeration tank 11 to ensure sufficient oxygen in the sewage; then the sewage enters the biochemical tank 12, and filter materials are set at the bottom of the biochemical tank 12. The filter materials include microbial filter materials and limestone pyrite The filter material, the microbial filter material is specifically actinomycetes and mold, the filter material is used to remove nitrate and nitrite ions in the water body, plants are planted in the degradation tank 13, and the sewage is further treated.

The invention discloses an inclined bottom type subsurface flow constructed wetland combined system, which comprises a sedimentation tank, an aeration tank, a biochemical tank and a degradation tank which are sequentially communicated, wherein a scraping plate in contact with the inner wall of the sedimentation tank is arranged in the sedimentation tank; a slide rail is embedded in the side wall of the sedimentation tank in the length direction of the sedimentation tank; sliding blocks connected into the sliding rail in a sliding mode are arranged on the two sides of the scraping plate; pulleyblocks are arranged on the side walls of the two ends of the sedimentation tank; each pulley block is sleeved with a rope; the rope is annularly arranged, and the two ends of the rope are fixed to the two sides of the scraping plate respectively; a through hole for discharging waste residues out of the sedimentation tank is formed in the side wall of one end of the sedimentation tank; a gate usedfor blocking the through hole is arranged in the through hole; and a briquetting device used for briquetting the waste residues is arranged at the end, away from the sedimentation tank, of the gate.The inclined bottom type subsurface flow constructed wetland combined system has the effect of preventing waste residues from being butted in the sedimentation tank.
Description
technical field [0001] The invention relates to the field of constructed wetlands, more specifically, it relates to an inclined bottom type subsurface flow constructed wetland combined system. Background technique [0002] The type of artificial subsurface wetland is a man-made landscape with hydrophilic plants as surface greening and sandy soil as filler to allow water to permeate and filter naturally. It has the characteristics of no surface water, small footprint, high utilization rate and convenient maintenance, and is deeply loved by people. Constructed wetlands are used to treat sewage. [0003] At present, the Chinese patent with the publication number CN105217893B discloses an inclined-bottom subsurface flow artificial wetland combination system, which includes at least three levels of pool units connected in series according to the slope gradient from top to bottom. The bottom of the pool is a slope surface, and from top to bottom are the aeration tank unit, the h...
