Study on the Effects of Domestic Sewage on Soluble Protein Content of Parts Constructed Wetland Plants

The study on the resistance of different wetland plants to wastewater duress is the key to ecological wastewater treatment technology. This paper studies the change of soluble protein content in 4 common wetland plants ( Phragmites communis, Typha angustata, Arundo donax and Canna generalis ) in Shandong in different wastewater duress time. The results show: when the wastewater duress time is 2 days and 4 days, soluble protein content in Phragmites communis has minimal change, and its anti-stress capability is the strongest; when the wastewater duress time is 6 days, soluble protein content in Canna generalis has minimal change, and its anti-stress capability is the strongest, followed by Typha angustata.
