高浓度pb废水对水平潜流湿地中菖蒲抗氧化特性的影响
With the rapid development of social economy in recent years, water environment pollution is serious, water quality deteriorating situation is increasingly serious, especially heavy metal pollution is particularly tricky. However constructed wetland as a new type of ecological sewage purification processing system, save investment, simple operation, high purifying water quality, stable running effect significantly, can also beautify the environment to improve environmental quality, the most important thing is that of heavy metal sewage purification effect become a research hotspot. This graduate design experiment is to pass the research level, the undercurrent wetland calamus oxidation resistance is affected by the content of pb, to distinguish calamus whether can be effective in the artificial wetland purification sewage plants containing pb. By comparing with different concentrations of pb in the artificial simulation of the wetland wastewater calamus on the absorption of pb and calamus oxidation resistance ability is affected, to study the calamus oxidation resistance ability in sewage treatment. The results of the study of artificial wetland plants configuration choice, artificial wetland for sewage purification and ecological protection and ecological restoration work has important significance.
