人工湿地植物受污水胁迫存在的问题与解决对策

Problems and solutions of constructed wetland plants under sewage duress

人工湿地植物是污水生态处理系统中的重要组成部分,研究其受污水胁迫面临的问题,寻求相应解决对策,可为人工湿地的合理构建和人工湿地植物的适当选择提供理论依据和技术支撑。研究阐述了人工湿地植物的作用、选择原则以及研究现状,分析了人工湿地植物受污水胁迫面临的主要问题:植物生长周期短、衰退和生长速度缓慢以及根系扩展不利等,提出人为干预、选择抗性强植株以及合理植物配置等解决途径和对策。

Constructed wetland plants play an important part in ecological treatment system of sewage. The study on the problems and solutions of constructed wetland plants under sewage duress can provide theoretical basis and technical support for the reasonable construction of wetlands and the reasonable selection of wetland plants. The paper describes the function, the selection principle and the research status of constructed wetland plants and analyzes the main problems of constructed wetland plants under water duress like the short plant growth cycle, recession, slow growth tots of root expansion. Countermeasures are proposed, such as human intervention, selection and so on. , unfavorable fac- reasonable plants
