Abstract

The invention belongs to the field of environmental engineering, and particularly relates to a constructed wetland device for sewage treatment and a use method thereof. According to the technical scheme, the constructed wetland device used for sewage treatment is characterized by comprising a processing constructed wetland unit and a terminal reinforced phosphorus removal constructed wetland unit, wherein the processing constructed wetland unit at least comprises three stages, and a water outlet pipe of the processing constructed wetland unit of the last stage is communicated with a water inlet area of the terminal reinforced phosphorus removal constructed wetland unit. According to the technical scheme, sewage enters the processing constructed wetland unit in sequence, the water outlet pipe of the processing constructed wetland unit of the last stage discharges water to the water inlet area of the terminal reinforced phosphorus removal constructed wetland unit, the retention time of the sewage in the reinforced phosphorus removal constructed wetland unit is 4-12 h, and finally the sewage is discharged from a system main water outlet pipe in the terminal reinforced phosphorus removal constructed wetland unit. According to the scheme, by means of the novel constructed wetland device for sewage treatment and the use method thereof, no residual sludge is generated, no residual sludge is generated in the running process of the device, daily maintenance is easy, and the treatment effect is good.

Description

technical field [0001] The invention belongs to the field of environmental engineering, in particular to an artificial wetland device for sewage treatment and a method for using the same. Background technique [0002] At present, most of the constructed wetlands used in my country are divided into surface flow wetlands and subsurface flow wetlands. The above-mentioned types of constructed wetlands generally have problems such as large area and easy blockage. Therefore, how to improve the structure of constructed wetlands and improve their reoxygenation effect to facilitate their treatment Efficiency has become a widely concerned issue. At present, the common method to improve the reoxygenation efficiency of constructed wetlands is often achieved by setting electric aerators. This method consumes electricity and energy and requires a large investment, so it is necessary to develop a new type of constructed wetland treatment process. Contents of the invention [0003] Ai...
