采用自行研制的阳电荷粒状滤材浓集５０、７０和１００Ｌ饮用水中的肠道病毒。当滤材体积一定时５０和７０Ｌ水的病毒平均回收率达９０％左右，而１００Ｌ水的病毒回收率仅为５０％，但适当增加滤料的体积即可提高回收率。该材料吸附容量相对较大，通水性能好且使用方便，可广泛用于水中肠道病毒的浓集检验。 Using self-developed positive charge granular filter 50, 70 and 100L concentration of enterovirus in drinking water. When the volume of filter medium is fixed, the average recoveries of 50 and 70L water viruses are about 90%, while the virus recovery rate of 100L water is only 50%. However, appropriately increasing the volume of filter media can increase the recovery rate. The material adsorption capacity is relatively large, good water flow and easy to use, can be widely used in the concentration of waterborne enterovirus test.
