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。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 CODCrand nutrient removal and influent modes were investigated. The results indicated that the combined process of VFW-DP can effectively remove CODCr,NH4＋-N and TP,and the average removal rate of CODCr,NH4＋-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 CODCr,NH4＋-N and TP are61. 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.
