垂直流人工湿地系统工程的污染物净化效率研究

将传统污水处理技术与人工湿地工艺相结合,通过将强化型前处理系统引入到高效垂直流人工湿地水质净化系统,从而提高了人工湿地的处理效率.9个月的实际运行证明,该预处理装置的设置降低了湿地负荷,提高了人工湿地对污水的净化效率,特别是对有机污染物有较好的去除效果.改良后的湿地系统对合流制污水污染物净化具有良好效果,且运行成本低,适用于土地资源比较丰富、资金紧张的地区. 

Study on Wastewater Purification Efficiency of Vertical Flow Constructed Wetland Systems

Artificial wetland was applied in combination with traditional wastewater treatment technology, and an intensified pre-treatment system was introduced to high-efficiency vertical flow constructed wetland so as to improve the wetland treatment. Through 9 months of running, it had been proved that the pretreatment setting declined the pollutant amount into the wetland, and increased the wastewater purification efficiency. The improved wetland system had the satisfactory purification effect on confluence sewage, and the cost was rather low. So the treat system is suitable to the areas which have relatively rich land but fewer funds.
