Problems solved by technology
[0005] The above methods can solve the problem of wetland blockage to a certain extent, but they have the characteristics of affecting the continuous operation of the wetland, high cost, and difficult to prevent. They cannot completely solve the blockage of the wetland, let alone solve the problem of anaerobic accumulation in the vertical flow constructed wetland. Seriously affected the application of constructed wetlands

The invention disclosed by the invention belongs to the technical field of sewage treatment, and is specifically a constructed wetland system and its operating method, including a water inlet pipe, a water inlet valve, no less than three vertical flow constructed wetland units, an air supply pipe, a water outlet pipe and a water outlet valve. The bottom of the constructed wetland unit is evenly arranged with water distribution pipes, the air supply pipes are vertically distributed on the top of the water distribution pipes, the water distribution pipes are distributed along the axis with two rows of horizontal water outlet holes, and the top of the constructed wetland unit is planted There are aquatic plants, and each constructed wetland unit is cyclically operating in the process of water intake, water storage, and drainage. Each cycle experiences a process of water inflow from bottom to top and drainage from top to bottom, allowing the water to flow instantly. The fine inorganic matter that falls off from the surface of the filler is washed away and discharged with the effluent, ensuring the long-term stable operation of the wetland. At the same time, the process of drainage is also an oxygenation process inside the wetland, which increases the purification efficiency of the wetland.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a constructed wetland system and an operation method. Background technique [0002] Constructed wetland mainly utilizes the physical, chemical and biological synergy of soil, artificial medium, plants and microorganisms to treat sewage. Its mechanism of action includes adsorption, retention, filtration, redox, precipitation, microbial decomposition, transformation, plant shading, residue accumulation, transpiration water and nutrient absorption, and the action of various animals. It has the characteristics of low investment and convenient operation and management. [0003] Judging from the existing engineering examples, the blockage of wetlands is the most likely to occur, especially in vertical flow constructed wetlands. At the same time, an anaerobic zone is formed at the bottom, which accelerates blockage and seriously affects the operation effect of wetlands. Accord...
