Embodiment 1

[0026] Such as figure 1 As shown, the system includes a submerged wetland pool body, water inlet pipe, outlet pipe, water distribution pipe and packing layer. During operation, sewage enters the system through the water inlet pipe 12, distributes water evenly, enters the packing layer, and the incoming water flows through the first Biochar layer 9, plant matrix layer 8, gravel layer 7, second biochar layer 6, composite biofiller layer 5, third biochar layer 4, inorganic filler layer 3 and the fourth biochar layer 2, after treatment The water is discharged out of the system through the outlet pipe 11. The plant matrix layer is composed of zeolite, biochar, fine sand, limestone and loam. The thickness of the plant matrix layer is 100mm. Wetland plants select canna for use in this embodiment. The thickness of the first biochar layer is 300mm, the thickness of the gravel layer is 100mm, the thickness of the second biochar layer is 200mm, the thickness of the third biochar layer in...

Embodiment 2

[0028] Such as figure 1As shown, the system includes a submerged wetland pool body, water inlet pipe, outlet pipe, water distribution pipe and packing layer. During operation, sewage enters the system through the water inlet pipe 12, distributes water evenly, enters the packing layer, and the incoming water flows through the first Biochar layer 9, plant matrix layer 8, gravel layer 7, second biochar layer 6, composite biofiller layer 5, third biochar layer 4, inorganic filler layer 3 and the fourth biochar layer 2, after treatment The water is discharged out of the system through the outlet pipe 11. The plant matrix layer is composed of zeolite, biochar, fine sand, limestone and loam. The thickness of the plant matrix layer is 150mm. In this embodiment, the wetland plants are reeds. The thickness of the first biochar layer is 350mm, the thickness of the gravel layer is 150mm, the thickness of the second biochar layer is 150mm, the thickness of the third biochar layer in the bi...

Embodiment 3

[0030] Such as figure 1 As shown, the system includes a submerged wetland pool body, water inlet pipe, outlet pipe, water distribution pipe and packing layer. During operation, sewage enters the system through the water inlet pipe 12, distributes water evenly, enters the packing layer, and the incoming water flows through the first Biochar layer 9, plant matrix layer 8, gravel layer 7, second biochar layer 6, composite biofiller layer 5, third biochar layer 4, inorganic filler layer 3 and the fourth biochar layer 2, after treatment The water is discharged outside the system through the outlet pipe 11. The plant matrix layer is made up of zeolite, biochar, fine sand, limestone and loam. The thickness of the plant matrix layer is 150mm. In this embodiment, the wetland plants select water sunflower for use. The thickness of the first biochar layer is 400mm, the thickness of the gravel layer is 200mm, the thickness of the second biochar layer is 300mm, and the thickness of the thi...

Abstract

The invention provides a system for improving the sewage treatment effect of a subsurface flow constructed wetland on the basis of biochar addition, and belongs to the field of sewage control. The system comprises a subsurface flow constructed wetland pool body, a water inlet pipe, a water outlet pipe, a water distribution pipe and a filling material layer, wherein the filling material layer sequentially comprises a plant substrate filling material layer, a biological filling material layer and an inorganic matter filling material layer from top to bottom in the vertical direction; the plant substrate filling material layer sequentially comprises a wetland plant, a first biological carbon layer, a plant substrate layer, a gravel layer and a second biological carbon layer from top to bottomin the vertical direction; the biological filling material layer sequentially comprises a composite biological filling material layer and a third biological carbon layer from top to bottom in the vertical direction; the inorganic matter filling material layer is zeolite, steel slag, ceramsite, cement and foaming agents; the water distribution pipe penetrates through the inside of the subsurface flow constructed wetland. The top of the filling material layer is communicated with the water inlet pipe; the bottom of the filling material layer is communicated with the water outlet pipe. The system effectively solves the problems of easy blockage and poor ammonia nitrogen removal effect of the subsurface flow constructed wetland.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a system for improving the treatment effect of subsurface flow artificial wetland sewage based on the addition of biochar. Background technique [0002] Constructed wetland is a composite system composed of filler (matrix), plants and microorganisms. Sewage and sludge are fed into the system in a controlled manner. During the flow of sewage and sludge in a certain direction, soil, artificial It is a technology that treats sewage and sludge through the triple synergy of physics, chemistry and biology of media, plants and microorganisms. It achieves efficient purification of pollutants through filtration, adsorption, co-precipitation, ion exchange, plant absorption and microbial decomposition. At the same time, through the biogeochemical cycle of nutrients and water, it promotes the growth of green plants and increases their production, so as to realize the purification of wastewate...
