几种不同浓缩技术回收水中病毒的效果
- COMPARISON OF SEVERAL FILTERS FOR VIRUS RECOVERY FROM DRINKING WATER AND TREATED SEWAGE
- 摘要：实验表明,即使病毒剂量低到一个感染性病毒也可使人感染,并可在人群间造成传播。因此,水环境的病毒污染深为人们关切。 水中的致病性病毒主要来自人和动物的排泄物及医院废水。目前已从各种水体中检测出120多种危及人类健康的肠道病毒和其它病毒。 世界卫生组织要求,用最灵敏的方法试验,在100-1000L饮用水中应不含病毒。因此,病毒的浓缩技术是监测水中病毒的前提。 现在国内外使用的浓缩技术方法很多,但都不甚理想。我们用几种不同的方法回收自来水和污水厂出水中实验性污染的病毒,以便选择具有快速、简便、适用性广泛、浓缩水样体积大和回收病毒效率高的技术。
- Abstract：The efficiencies of IMDS Virosorb positively charged cartridge filter, IMDS positively charged disc filter,MK positively charged cartridge filter and talcum powder-diatomite procedure for virus recovery from drinking water and treated sewage were examined and compared. The average recovery rates for drinking water virus were found to be 63.69%, 45.38% and 65.27% for IMDS cartridge filter,MK cartridge filter and talcum powder-diatomite respectively and the average rates of IMDS disc filter and talcum powder-diatomite for sewage virus recovery were 53.71% and 53.3%.
