Description

technical field

[0001] The invention belongs to the utilization of artificial wetlands, in particular to a method for treating sewage by using artificial wetlands. Background technique

[0002] Constructed wetland technology is a sewage treatment process developed in recent years. Due to its characteristics of low investment, low energy consumption, and low treatment cost, it has gradually been widely accepted. Constructed wetland is an artificially constructed complex ecosystem, and its various parts interact to remove pollutants through the comprehensive action of plants, substrates and microorganisms. In actual operation, after the constructed wetland operates for a long time, the system is prone to blockage, the function of the wetland is reduced, the purification ability of pollutants is reduced, and the effluent cannot be discharged up to the standard. The main reasons are:

[0003] 1. Sewage enters the wetland system directly without pretreatment, resulting in the g...
