摘要

摘要: 以处理模拟污染河水的垂直流人工湿地-滞留塘(VFW-DP)组合工艺为研究对象,通过试验考察了温度对组合工艺COD_Cr去除和脱氮除磷效果的影响,同时探讨了不同进水方式对组合工艺去除污染物效果的影响。结果表明:VFW-DP对COD_Cr、$NH_{4}^{+}$-N和TP具有较好的去除效果,COD_Cr、$NH_{4}^{+}$-N和TP的平均去除率分别大于47.9%、60.0%、27.5%。在运行初期(中温期),下行式垂直流人工湿地-滞留塘(DVFW-DP)对COD_Cr、$NH_{4}^{+}$-N和TP的去除率分别为61.7%、77.1%和19.9%;上行式垂直流人工湿地-滞留塘(UVFW-DP)的去除率分别为29.5%、53.5%和35.9%:下行式进水方式更利于污染物的去除。温度对污染物的去除效果影响明显,VFW-DP在高温期的去除效果明显优于中温期和低温期。

Abstract: The combined process of vertical flow constructed wetland-detention pond (VFW-DP) was constructed to treat simulated contaminated river water. The effect of temperature on COD_Crand nutrient removal and influent modes were investigated. The results indicated that the combined process of VFW-DP can effectively remove COD_Cr, $NH_{4}^{+}$-N and TP, and the average removal rate of COD_Cr, $NH_{4}^{+}$-N and TP are higher than 47.9%, 60.0% and 27.5%, respectively. At initial operating stage (medium temperature period), the removal rate of downward vertical flow constructed wetland-detention pond (DVFW-DP) for COD_Cr, $NH_{4}^{+}$-N and TP are 61.7%, 77.1% and 19.9%, respectively, and the removal rate of upward vertical flow constructed wetland-detention pond (UVFW-DP) are 29.5%, 53.5% and 35.9%, respectively, thus the down-flow influent mode is more beneficial to removal pollutants. Temperature can significantly affect the removal of pollutants; at high temperature period, the effect of pollutants removal is significantly better than that at medium temperature and low temperature period.
