摘要
采用了基于狭叶香蒲的垂直流湿地和稻壳过滤体系(VFCW),结合吸附钴沸石催化臭氧化合物(Co-zeotype/O_(3)),处理城市污水。经过优化后,VFCW/Co-zeotype/O_(3)工艺的处理效果明显,可去除污水中约89%的BOD_(5)、93%的COD和97%的TKN。此外,还观察到VFCW/Co-zeotype/O_(3)工艺可将污水中90%以上的重金属(如Cr、Cu、Cd、Fe、Ni和Zn)去除。因此,VFCW/Co-zeotype/O_(3)工艺有望成为传统城市污水处理方法的替代方案。
A vertical-flow wetland and rice husk filtration system(VFCW) based on narrow-leaved balsam pads combined with a loaded cobalt zeolite-catalyzed ozone compound(Co-zeotype/O_(3)) was used for the first time to treat municipal wastewater.After optimization,the treatment effect of VFCW/Co-zeotype/O_(3) process was obvious,the removal rate of BOD_(5) was about 89%,the removal rate of COD was 93% and the removal rate of TKN was 97%.In addition,it was observed that the VFCW/Co-zeotype/O_(3) process could remove more than 90% of heavy metals(e.g.Cr,Cu,Cd,Fe,Ni and Zn) from the wastewater.Therefore,it can be concluded that the VFCW/Co-zeotype/O_(3) process is expected to be an alternative to traditional municipal government wastewater treatment methods.
