Analysis of Total Phosphorus Removal Efficiency of Constructed Wetland in Sewage Treatment Plant at Different Times
The constructed wetland has a good total phosphorus removal effect,but the total phosphorus removal efficiency is affected by seasonal changes.Through the study of the total phosphorus removal efficiency of the constructed wetland for one year,the results show that the average monthly total phosphorus removal amount and removal rate of the constructed wetland throughout the year are 0.030 mg/L and 22.70％,respectively.The average total phosphorus removal amount in September and October is the highest,and the average total phosphorus removal rate in October is the highest;The average removal amount and removal rate of total phosphorus in January were the lowest;The average removal rate of total phosphorus is the highest in autumn and the lowest in winter.The research results have guiding significance for the design,construction and operation of sewage treatment plants.
