In the situation of varied water quality of influent, membrane permeate COD was all less than 20mg/L, NH〓-N was less than 1mg/L and turbidity was less than 1 NTU. Because the membrane surface formed gel layer in the filtration process, which reduced membrane pore size efficiently removed nosogenetic germ and virus and attained the demand of water quality standard in wastewater reuse.
在进水水质波动的情况下,膜出水COD值均小于20mg/L,NH〓-N小于1mg/L,浊度小于1NTU;由于在过滤过程中膜面形成了凝胶层,起到了减小膜孔径的作用,从而达到致病菌和病毒的有效去除,能够满足污水回用于杂用水时对水质的要求。

With retention time prolonged, the concentrations of TN, NH4(superscript +)-N and TP of domestic sewage were obviously reduced in all floating-bed systems, however the NO4(superscript +)-N concentrations were gradualjy accumulated due to the stronger nitrification than denitrification. The plants in floating-bed system increased significantly the N2O flux, which was 174.44μg/(m^2h), 82.19μg/(m^2h), 112. 49μg/(m^2h) and 44.81μg/(m^2h), respectively, for the Lolium mutliflorum, Oenanthe javanica, Vetiveria Zizanioides arid none-plant floating-bed systems.
净化周期内,浮床各系统的TN、NH4-N和TP浓度随着污水停留时间的延长直线下降,而NO3-N浓度却因系统内硝化强度大于反硝化强度而产生了累积;植物的存在明显的促进了浮床系统的N2O排放,浮床黑麦草、水芹、香根草和对照系统N2O的平均排放通量分别为174.44μg/, 82.19μg/, 112.49μg/和44.81μg。

Among the economic crops, pachyrhizus leaf had the most remarkable treating effect, the COD treating capacity per day per unit area was 4.01g, that is, a 50% treating rate; the BOD treating capacity was 1.15 g, that is, a 35% treating rate; the TP treating capacity was 0.23 g, that is, a 16% treating rate; the TN treating capacity was 1.87 g, that is, a 74% treating rate; however, the treating effect decreased as the total amount of pollution entering this system increased by raising the water volume, which was mainly owing to the relatively short hydraulic retention time.
由水质试验结果显示,本系统所选用的作物处理生活污水成效极佳,优於一般湿地选用的植物,以及河滩地原生草种型态,其中以地瓜叶的处理成效最为显著,每日单位面积COD去除速率为4.01 g 、处理效率达50﹪;BOD去除速率为1.15 g 、处理效率达35﹪;TP去除速率为0.23 g 、处理效率达16﹪;TN去除速率为1.87 g 、处理效率74﹪,而以加大水量的方式,增加进入本系统之污染总量,其处理成效减低,主要原因受到水力停留时间较短影响,未来可以增加处理面积、水力停留时间加长、提高原水浓度为后续之研究方向,以达到增加本系统处理成效之目的。
