人工湿地污水处理系统工艺设计研究

本文阐述了人工湿地污水处理系统工艺设计的主要内容及存在的若干问题，提出了开展人工湿地工艺设计研究的一些设想。人工湿地工艺设计研究包括人工湿地基质构建、植物群落构建和人工湿地构造与工程参数三个方面。目前，由于在污染物净化机理、系统水力学和污染物降解动力学等方面认识不足，制约了人工湿地工艺设计水平的提高，因此，深入研究污染物净化机理、开展人工湿地基质与植物筛选与组合研究、创建适合植物生长的人工生境、优化水力学模型和污染物降解动力学模型．将有利于提高人工湿地工艺设计水平。

Study on the Process Design of Wastewater Treatment System of Constructed Wetland

The main contents and problems of the process design of constructed wetland for wastewater treatment are summarized, and some research interests are proposed in this paper. The process design of wastewater treatment system of constructed wetland consists of the construction of substrate and maerophyte species, the configuration and design parameters of constructed wetland. However, deficient researches on the mechanism of wastewater purification, the hydraulics of system, and the kinetics of wastes degradation affect the improvement of the process design of constructed wetland. In order to raise the level of process design of constructed wetland, and wastewater purification function of constructed wetland, it is necessary to carry out the researches on purification function, selection and assembly of substrate and macrophyte species, and build suitable artificial habitats for macrophyte growth, and optimize hydraulic models and kinetic models of constructed wetland.
