摘要
采用狗牙根草坪草种植的人工绿地对受污染景观水进行处理,结果表明,在低水力负荷0.2m3/(m2.d)的条件下,对COD,TN和TP的去除率分别为55.6%-78.3%,54.3%-90.7%和28.5%-85.6%。人工绿地对COD和TN的去除效果较为稳定,进、出水COD和TN变化趋势较为一致;人工绿地对TP的去除率随处理周期的延长呈下降趋势,但即使在后期,TP去除率亦可达到20%-30%。
The polluted landscape water was treated with greenland by planting bermudagrass.The results show that the removal of COD,total nitrogen and total phosphorus is 55.6%～78.3%,4.3%～90.7% and 28.5%～85.6% respectively with the hydraulic loading rate;the removal of COD and total nitrogen are relatively steady,and the COD and TN of effluent are related to that of influent;the removal of TP is declined with the time extending,however even more than 20%～30% in the late duration.
