Analysis on Affected Factors of Treatment Efficiency of Rural Sewage Removal with Constructed Wetland

Abstract Sewage treatment in rural areas is relatively lower. Most of the sewage discharged into the environment directly without any treatment. More and more severe environmental problems are threatening the rural situation. As an effective rural sewage treatment method, constructed wetland wastewater treatment technique had played an important role in the rural sewage treatment. In this paper, the constructed wetlands of Luqiao Village of Xiake Town in Jiangyin were taken as a case to explore the mechanism and effects of decontamination of constructed wetland. By using PCA method, the relationships between the removal efficiency of constructed wetlands and water temperature, water quantity, water loads, influent concentration and pH are analyzed quantitative The results showed that constructed wetland has a high rural sewage removal rate; and the water temperature, water loads, influent concentration have a greater impact on the rural sewage removal rate than water quantity and PH. The results are helpful in providing a technical reference for further improving the treatment efficiency of rural sewage removal with constructed wetland ecological system
