Study on the Effects of Wastewater Duress on MDA in Constructed Wetland Plants

Abstract

The study on the wetland plant species and their resistance is the key to ecological wastewater treatment technology. The study on the effects of wastewater duress on the physical and chemical properties of constructed wetland plants and the anti-stress capability of constructed wetland plants can provide theoretical basis and technical support for constructed wetland plant material selection. By adopting surface flow constructed wetland system, the effects are studied on MDA in 4 common plants in Shandong (Phragmites communis, Typha oriental, Arundo donax and Canna generalis) in different wastewater duress time. The results show: All in all, Phragmites communis and Canna generalis have stronger anti-stress capability, while Arundo donax and Typha oriental has weaker anti-stress capability; but as wastewater duress time increases, the anti-stress capability of Phragmites communis decreases, while the anti-stress capability of Canna generalis increases.

Study on the Effects of Wastewater Duress on Chlorophyll Content of 4 Species Wetland Plants

“…At present, the researches on wetland plants are mostly concentrated on pollution absorption or purification ability and plant selection. Little research has been done in plant resistance [6][7]. The paper studies the changes of Chlorophyll Content in different constructed wetland plants in different wastewater duress time to provide theoretical basis and technical support for choosing wetland plants in constructed wetland ecological wastewater treatment in Shandong region.…”
