Abstract

The invention relates to a vertical-flow constructed wetland device, in particular to a constructed wetland device for advanced treatment of domestic sewage. The constructed wetland device is a vertical-turning-flow constructed wetland which has the functions of enhancing nitrification and denitrification, improving purification effect and the like, and can improve a constructed wetland system and reduce installation and maintenance cost. The vertical-turning-flow comprises an inner cylinder, an outer cylinder and a matrix hopper, wherein the inner cylinder is a hollow cylinder with an opening in the upper end; the outer cylinder is a hollow cylinder with an opening in the upper end and coincides with the vertical center line of the inner cylinder; and the matrix hopper is of a hollow cuboid-like structure with an opening in the upper end. According to the device, the denitrification effect of nitrate nitrogen is enhanced through a flooding saturation area of the central inner cylinder; and through multiple layers of inner and outer cylinder spacing plates and the matrix hopper, a trickling filtration aerobic zone is formed, the nitrification effect of ammoniacal nitrogen is enhanced, a water body is baffled for times to prolong hydraulic retention time, and a space utilization rate is increased, thereby lowering land cost.

Description

technical field [0001] The invention belongs to the field of constructed wetlands, and provides a constructed wetland device for advanced treatment of domestic sewage, which has the functions of strengthening nitrification and denitrification, enhancing purification effects, etc., can improve the constructed wetland system, improve space utilization, and facilitate installation and maintenance The vertical turning flow constructed wetland. Background technique [0002] Since oxygen can enter the wetland system through atmospheric diffusion and plant transport in vertical flow wetlands, its internal oxygenation is more sufficient, which is conducive to the growth of aerobic microorganisms and the progress of digestive reactions, and the removal effect of nitrogen and phosphorus is better. Vertical flow wetlands are divided into two types: downflow and upflow. Downflow vertical flow wetlands are more commonly used because of their relatively simple operation. Sewage flows in f...
