摘要
通过自制的人工湿地处理系统,研究了相同装置有无设置挡板情况下的处理效果。研究表明:在同样的水力负荷(0.1～0.5 m3/(m2·d))条件下,设置挡板,可有效提高系统的去除率。但在水力负荷为0.1、0.2m3/(m2·d)时,设置挡板的系统易产生死水区,而随着水力负荷的提高,可改善这一状况。研究结果对人工湿地处理系统的应用具有一定的参考意义。
It has been investigated that how the treatment effect was under the same device which has baffle or not through a constructed wetland treatment system. The results show that the baffle could effectively improve the removal rate under the condition of same hydraulic loading [0.1 m3/（m2·h） ～ 0.5 m3/（m2·h）]. But the system of setting baffle, when hydraulic loading was 0.1 or 0.2 m3/（m2·h）, easily produced a stagnant water. The situation could be improved with increased hydraulic loading. The studying results have some reference significance to application of constructed wetland treatment system.
