Abstract

Adsorption of poliovirus and rotavirus by aluminum hydroxide and activated sludge flocs was studied. Both aluminum hydroxide and activated sludge flocs adsorbed greater amounts of poliovirus than rotavirus. Aluminum hydroxide flocs reduced the titer of poliovirus in tap water by 3 log10, but they only reduced the titer of a simian rotovirus (SA-11) in tap water by 1 log10 or less and did not noticeably reduce the number of human rotavirus particles present in a dilute stool suspension. Activated sludge flocs reduced the titer of added poliovirus by 0.7 to 1.8 log10 and reduced the titer of SA-11 by 0.5 log10 or less. These studies indicate that a basic difference in the adsorptive behavior of enteroviruses and rotaviruses exists and that water and wastewater treatment processes that are highly effective in removal of enteroviruses may not be as effective in removing other viral groups such as rotaviruses.

摘要

研究了氢氧化铝和活性污泥絮凝物对脊髓灰质炎病毒和轮状病毒的吸附作用。氢氧化铝和活性污泥絮凝物对脊髓灰质炎病毒的吸附量均大于轮状病毒。氢氧化铝絮凝物可使自来水中脊髓灰质炎病毒的滴度降低3个对数级,但对自来水中猿猴轮状病毒(SA - 11)的滴度仅降低1个对数级或更低,且对稀释粪便悬液中存在的人类轮状病毒颗粒数量无明显减少作用。活性污泥絮凝物可使添加的脊髓灰质炎病毒滴度降低0.7至1.8个对数级,使SA - 11的滴度降低0.5个对数级或更低。这些研究表明,肠道病毒和轮状病毒的吸附行为存在根本差异,对去除肠道病毒非常有效的水和废水处理工艺,在去除其他病毒组(如轮状病毒)方面可能效果不佳。
