Embodiment 1
[0039] Construct two constructed wetlands with the same facilities as follows:
[0040] The bottom surface of the pool body 17 is 1.5m×1.5m, the height is 2m, and it is filled with the substrate 16 (from the surface of the wetland to the bottom, the gravel is filled in small to large sizes, and bio-ceramsite is added near the root zone), and reeds are planted on the surface of the substrate. The size of the pulse-type sump is 6L, the water flow rate of the water inlet pipe is 37L / h, and the water distribution interval is eight minutes. Three water distribution branch pipes 6 are evenly buried in the same horizontal plane 30cm from the upper surface of the substrate 16, and the water distribution aperture is 5-7mm. , the opening rate is 25-40%; two air pipes 13 are evenly buried in the same horizontal plane at a distance of 80 cm from the upper surface of the substrate 16, and the opening rate is 30-70%;
[0041] The different facilities are as follows:

Abstract
The invention relates to a wastewater treatment system for environmental engineering and particularly relates to a wind-energy superimposed-negative-pressure ventilation reoxygenation wastewater treatment system for an artificial wetland. In order to solve the technical problem of low oxygen content in the artificial wetland of the existing artificial wetland wastewater treatment system during the treatment of wastewater, the invention provides the wind-energy superimposed-negative-pressure ventilation reoxygenation wastewater treatment system for the artificial wetland. The wind-energy superimposed-negative-pressure ventilation reoxygenation wastewater treatment system for the artificial wetland is characterized in that a ventilation system drives a windmill and fan blades connected withthe windmill to rotate by using wind energies so as to form superimposed negative pressure, a diameter-reducing ventilation pipe, of which the other end is communicated with the atmosphere through anupward short pipe, is pumped to generate enhanced negative pressure, the flow and diffusion of air in a pipeline are increased, the reoxygenation of the wetland is intensified, and thus the degradation and nitrification reaction of aerobionts are promoted. The wind-energy superimposed-negative-pressure ventilation reoxygenation wastewater treatment system for the artificial wetland has the advantages of sufficient utilization of wind energy and pressure energy, intensification in reoxygenation, high denitrification efficiency, good purifying effect and the like.
Description
technical field [0001] The invention relates to an environmental engineering sewage treatment system, in particular to a wind energy superimposed negative pressure ventilation re-oxygenation artificial wetland sewage treatment system. Background technique [0002] Constructed wetland sewage treatment technology is a new technology for sewage ecological treatment developed in the 1970s. Its principle is to use the synergy between plants, microorganisms and fillers in constructed wetlands to improve water quality, and has a good social, economic and ecological environment. benefit. [0003] In actual engineering, the generally low oxygen content is an important factor restricting the sewage purification of constructed wetlands. Insufficient oxygen content will easily lead to low aerobic biological activity and insufficient ammonia nitrogen nitrification, and low purification and denitrification efficiency. In order to overcome the above defects, in the process of wetland con...
