摘    要:目的]为了缓解人工湿地的堵塞问题,探讨水力负荷对垂直流人工湿地堵塞的的影响。方法]该试验通过人工土柱模拟垂直流人工湿地,设置4个水力负荷水平即50、100、150、200 cm/d,找出水力负荷对人工湿地堵塞的影响,并探索该因素运行过程的阈值。结果]不同水力负荷水平在人工湿地堵塞过程中影响较大,在高水力负荷条件200 cm/d下,系统有效使用寿命只有半年时间,而且可以推测单因素水力负荷的阈值应该处于100~150 cm/d之间;低水力负荷系统的运行时间还可以持续6个月,中水力负荷系统的运行时间还可以持续3个月。结论]对以后湿地堵塞试验提供分析依据。

关 键 词:垂直流人工湿地  堵塞  水力负荷  阈值

Abstract:Objective] The aim was to al eviate the constructed wetland clogging problems and to explore to the effects of hydraulic loading on wetland clogging. Method] The experiment, through artificial soil columns, simulated vertical flow arti-ficial wetland, set four hydraulic load level at 50, 100, 150 and 200 cm/d, to identify the impact of hydraulic loading on wetland clogging and to explore the factors run-ning threshold. Result] The results show that the different levels of hydraulic loading have greater impact; in the constructed wetland clogging process under high hy-draulic loading of 200 cm/d, the effective life was only six months, and the single factor can be speculated that the threshold of the hydraulic load should be at 100-150 cm/d; system can last for six months at low hydraulic loading and last for three months at medium hydraulic load. Conclusion] The research provides references for wetland clogging experiments in future.
Keywords:Vertical flow constructed wetlands  Clogging  Hydraulic loading  Threshold
