Embodiment Construction
[0024] like figure 1 As shown, the present invention includes a filter tank 1, a composite biological filter tank 2, and an artificial wetland tank 3 arranged at intervals in sequence. There is a first connecting pipe 5 connected between the two sides, and a second connecting pipe 6 is connected between the other side of the lower part of the composite biofilter 2 and the top of the constructed wetland pool 3. The first connecting pipe 5 and the second connecting pipe 6 Both are provided with a water pump 7, and the lower part of the artificial wetland pool 3 is connected with a water outlet pipe 8, and a water outlet valve is arranged on the water outlet pipe 8. like figure 2 As shown, the composite biological filter 2 includes a first pool body 9 with an open top, inside the first pool body 9 is fixed a partition plate 10 arranged vertically upward, and an overflow hole 11 is provided on the top of the partition plate 10 , the partition plate 10 divides the inside of the ...

The invention relates to a constructed wetland sewage advanced treatment device with a biological filter, which comprises a filter tank, a composite biological filter and a constructed wetland tank which are communicated in sequence, the composite biological filter comprises a first tank body, a partition plate is fixed in the first tank body, and an overflow hole is formed in the upper part of the partition plate; a partition plate is arranged in the first tank body and divides the interior of the first tank body into a first-stage biological filter and a second-stage biological filter, a deodorization mechanism is arranged at the top of the first-stage biological filter, and a cedar bark layer, suspended ball filler, a cobblestone layer and an aeration mechanism are sequentially arranged in the first-stage biological filter from top to bottom; a rotating roller is rotatably connected to the upper part of the interior of the secondary biological filter, filler wires are uniformly distributed on the periphery of the rotating roller, a filter screen is detachably connected to the interior of the secondary biological filter located below the rotating roller, a plurality of nylon ropes are fixed to the bottom of the filter screen, and a plurality of filler rings are fixed to the nylon ropes. The technical problems that an existing constructed wetland sewage treatment device is low in purification efficiency and poor in nitrogen and phosphorus removal effect are solved.
Description
technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an artificial wetland sewage advanced treatment device with a biological filter tank. Background technique [0002] Constructed wetland is a ground similar to swampland that is artificially constructed and operated under control. Sewage and sludge are distributed to the artificially constructed wetland in a controlled manner. When sewage and sludge flow in a certain direction, they are mainly used It is a technology for treating sewage and sludge through the triple synergy of physics, chemistry and biology of soil, artificial medium, plants and microorganisms. The purification principles of constructed wetlands include adsorption, retention, filtration, redox, precipitation, microbial decomposition, transformation, plant shading, residue accumulation, transpiration of water and nutrient absorption, and the action of various animals. [0003] When the constructed wetland...
