Study on the Linear Regression Model of Nitrogen Removal Influence Factors in Constructed Wetland Technology

For accurate test on the influence factors of nitrogen removal in constructed wetland technology, experiment to simulate the integrated vertical-flow constructed wetland processing of central drainage water in Shenyang Architecture University, mainly analysis the efficiency of nitrogen removal. The results show that we ultimately determine the influencing factors on the removal rate of nitrogen effect model by analyzing the data through multiple linear regression method. It is proved that the prediction results were exact, and can be used to guide the eutrophic landscape water body treatment and pollution control field Construction of constructed wetland technology in China.
