当在废水回收系统中安装能够有效减少病毒的超滤（UF）膜工艺时，水传播疾病的卫生安全保障至关重要。肠道病毒如腺病毒、轮状病毒和诺如病毒（NV）在污水中的检出率较高，了解它们的行为是很重要的。本研究以超滤膜工艺处理中水为研究对象，在中试装置中考虑进水浓度波动，采用混凝沉淀作为预处理工艺，考察超滤膜工艺对NV型GI和GII的去除效果。超滤膜工艺对GI和GII的去除率分别为3.3±0.7 Log GI和3.6±1.0 Log GII，不同NV种类型对GI和GII的去除率无明显差异。仅进行混凝沉淀预处理时，NV - GII去除率比超滤膜工艺平均提高约0.6 Log（4.2±1.1 Log）。然而，通过混凝沉淀过程去除NV GI的效果没有显著差异。
When ultrafiltration (UF) membrane processes that are able to effectively reduce viruses are installed in a waste water reclamation system, the security of sanitation safety for water-borne diseases is essential. It is important to understand the behaviour of enteric viruses such as Adenovirus, Rotavirus and Norovirus (NV), the detection rate of which is relatively high in sewage. This study focused on the UF membrane process for the reclaimed water treatment process, and investigated the removal performance in NV type GI and GII in the UF membrane process by performing coagulation and sedimentation as the pre-treatment process in a pilot-plant by considering the concentration fluctuation of the influent. The removal ratio of GI and GII by the UF membrane process alone was 3.3 ± 0.7 Log in GI and 3.6 ± 1.0 Log in GII, and no clear difference in the removal ratio by NV species type was observed. The removal ratio of NV GII was increased by about 0.6 Log on average (4.2 ± 1.1 Log) compared with the UF membrane process only when the coagulation and sedimentation process were conducted as pre-treatment. However, there was no significant difference in the removal of NV GI by conducting the coagulation and sedimentation process.
