Abstract
Due to the influence of low temperature in winter, the removal effect of pollutants in constructed wetlands in winter is greatly reduced. In order to improve the removal effect of wetland on pollutants such as nitrogen and phosphorus, this paper proposes a new insulation method that uses the residual heat of bathroom bath waste water to supply heat to the constructed wetland. In the proposed new wetland system, the average removal rates of TN, TP and NH4
+-N in wetlands reached 61.09%, 85.03% and 33.85%, respectively. The application of residual heat energy to the construction of constructed wetland can realize the recovery and utilization of energy, which is conducive to the promotion and application of constructed wetland in the cold regions of the north.
