Constructed Wetlands Sewage Treatment Technology Purification Mechanism and Influence Factors

摘要

Constructed wetlands are new sewage treatment technology, which have advantages of good decontamination effect, low operating costs and easy maintenance. Base on analysis of constructed wetlands composition and purification mechanism, the constructed wetlands purification influence factors are summarized, and the problems and solutions of constructed wetlands are pointed out. Carrying out in-depth study on constructed wetlands design, operational control and maintenance management to improve comprehensive benefits of wetland sewage purification technology, have great practical significance and far-reaching social significance.
