摘要
对山东省临沂市武河湿地的实地考察及水样采样,并对水体中的N、P、COD、BOD等水质指标进行测定与分析,试验结果证明武河人工湿地对TN、COD、BOD的去除率分别为55%、76%与70%,对P的去除率较低。武河湿地8个采样点的TN平均浓度为26.55 mg/L,TP平均浓度为0.125 mg/L。根据Thomas的水体富营养化程度划分标准分析,武河湿地水体的总磷与总氮含量均处于"富"级富营养化程度,所以武河湿地水体富营养化程度整体较高,对污水处理潜力未能得到充分发挥。
The authors had a field trip to wetlands of Wu River in Linyi, Shandong Province, collected samples to determine and analyze water quality indexes, such as N, P, COD and BOD. The experimental results showed that the constructed wetlands could remove 55% of TN, 76% of COD and 70% of BOD, but only had a low removal rate of P. The average concentration of TN and TP of eight sample points were 26.55 and 0. 125 mg/L, respectively. According to the standard of eutrophication degree analysis （Thomas）, the TP and TN of Wu River wetlands are in the rich degree of eutrophication level. Therefore, the eutrophication degree of constructed wetlands of Wu River is high overall, indicating that wastewater treatment does not develop well.
