Design and Analysis of Tail Water Purification of Sewage Treatment Plant Based on Constructed Wetland Technology
This paper introduces a process scheme of"strengthening the combination of phreatic water flow,multi-stage surface flow in series,and river corridor constructed wetland",which makes use of the physical,chemical and biological effects of wetland to deeply purify the river channel,build overflow weirs in the river channel,build multi-stage surface flow wetland and river corridor constructed wetland,and regulate the river channel,so as to achieve the goal of water purification and ecological recovery.
