摘　　要：基于阶式功能强化指导思想和试验研究技术支撑,以泗洪县城北污水处理厂三级处理尾水湿地净化为例,提出污水处理厂尾水阶式功能强化湿地处理工艺并应用于该工程设计,以强化TN、TP等污染物的去除。通过MIKE21软件模拟预测分析湿地结构和流场特征以及环境因子浓度场分布,指导湿地结构设计和流场优化,并模拟阶式功能强化湿地对污水处理厂尾水的净化效果,有效去除水体有机污染物,改善污水复氧条件,对水体氮磷污染物去除有明显作用,设计TN、TP去除率不小于20%。将其应用于泗洪县城北污水处理厂三级处理尾水净化提质具有较好的技术适应性,是湿地净化污水处理厂尾水理论与技术的有效实践。Based on stepped function enhanced guiding ideology and experimental research technical support,taking the tertiary treatment of tail water wetland purification in Sihong County as an example,stepped function enhanced wetland design method for WWTP tail water treatment is proposed and applied to engineering design for enhanced pollutants removal such as TN and TP.Wetland structure,flow field characteristics and environmental factor concentration field distribution are sumulated by MIKE21 software for better wetland structure design and flow field optimization.The purification effect of stepped function enhanced wetland processing sewage treatment plant tail water is also simulated by MIKE21 software.Effective removal of organic pollutants in wastewater treatment plant tail water,improvement of oxygen enrichment conditions in sewage,more than 20%significant removal of nitrogen and phosphorus pollutants in water will be achieved by stepped function enhanced wetland.Good technical adaptability and effective practice for wetland purification of wastewater treatment plant tail water theory and technology will be achieved when wetland is applied to the tertiary treatment of low organic concentration water purification and upgrading of Chengbei WWTP Sihong County.
