摘要
动态模拟试验结果表明,凤眼莲对含银废水具有很强的净化能力.当污水停留时间为24—48h时,银的净化率达98.6%以上,BOD_5为91.0%,COD_(Cr)为44.6%,浊度为91.1%,总磷(TP)为53.9%,NH_4^+-N为40.4%,NO_2^--N为92.9%,NO_3^--N为37.6%,PO_4^(3-)为56.8%.它与同期运行的活性污泥法相比较,效果要好.
The results of a simulation experiment on the purification of silver-bearing wastewater from a cinefilm factory in Wuxi using water hyacinth (Eichhornia crassipes) indicated that with a detention time of 24 to 48 hours, the purification rates were 98.6%, 91.0%, 44.0%,91.1%, 53.9%, 40.4%, 92.9%, 37.6% and 56.8% for Ag, BOD5, COD, SS, TP, NH4-N, NO2-N, NO3-N and PO43- respectively.
