| 摘 要： | 通过小试试验研究了由塘系统、垂直流、推流床单元组成的人工湿地工艺系统组合在内部不同空间上除磷的净化效应。结果发现,在高水力负荷下运行一段时间后,各套组合工艺系统对磷的净化效率均出现了不同程度的下降,其中下行池单元表层对磷的去除效率下降得最为显著;在各种组合中,塘单元对磷的净化效果并不理想。但是好氧塘单元与湿地的联用却可以有效地避免正磷酸盐释放的问题。

| Abstract: | The purification effect of phosphorus removal by various combined processed constructed wetland system including pond, vertical flow and surface flow units was studied, and results indicated that each wetland unit decreased the ability of removing phosphorus under high hydraulic loading at an interval about one year. Removal efficiency of phosphorus decreased in down-flow unit was the most rapid compared with all other kind of units, especially in upper layer. The pond system was limited in treating phosphorus, but can effectively avoid the phosphorus release. |
