摘要

以华北某市开发区波式潜流人工湿地(W-SFCW)中试系统为研究对象

研究其处理环卫河景观水体的效果。在4个多月的连续运行期中

对COD

TN和TP等指标进行监测。监测结果表明

W-SFCW对化学需氧量(COD)

TN和TP的去除率分别达到32.45%

43.35%和39.24%

其中TN和TP的平均出水浓度达到《地表水环境质量标准(GB3838-2002)》中Ⅳ类水标准。并用单因素方差分析对比了春、夏、秋3个季节下W-SFCW处理景观水体的效果

发现季节的变化对TN和COD的去除影响显著

对TP的去除影响不明显。提出了保障W-SFCW稳定运行的措施

为W-SFCW在修复景观水体水质上的应用以及实际工程中的维护管理提供依据。

Abstract

The wavy subsurface flow constructed wetland(W-SFCW)pilot system in a development zone inNorthern China was selected as the researching object to discuss the treatment effects on the scenic water ofthe river.Parameters including COD

TN and TP were monitored during a continuous operational period ofmore than 4months.The results showed that the removal efficiency of COD

TN and TP achieved 32.45%

43.35%and 39.24%respectively.The average effluent concentrations of TN and TP met the classⅣof surface water environmental quality regulation(GB3838-2002).By comparing the different effects in spring

summer and autumn using single factor analysis of variance

it was found that seasonal variations affected theremoval of COD and TN significantly

but the influence on TP removal was minimal.Based on these findings

some measures were proposed to insure the stable operation of W-SFCW

which provides the foundation for the application of W-SFCW to restoring scenic water and the maintenance in management and engineering.
