摘要: Willows are a group of versatile tree species that may have multiple environmental applications. In the present study, Salix jiangsuensis J172 plants were grown in fixed mats as an economic plant-based treatment system to evaluate its potential for removing nutrients wastewater. Plants grew normally wastewater compared with those Hoagland solution. However, containing high concentration chlorine ions was toxic S. plants. The accumulated large amounts nitrogen and phosphorus aboveground tissues under conditions abundant supply. removal efficiency raw 82.18-87.78 % nitrogen, 57.35-65.58 phosphorus, 58.24-59.90 chemical oxygen demand. Nutrient positively correlated initial nutrient results show mat nutrient-rich, eutrophic water be effective, low-cost phytoremediation technology treat undesirable levels
