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。
