中文摘要：

介绍了一种城市污水中肠道病毒的浓集方法：病毒浓集前在污水中加入带阳电荷的物质聚氯化铝,30 mg/L的聚氯化铝可使f2噬菌体回收率达到（92.06±8.65）%,pH值为6.5时f2回收率达（92.15±6.02）%,温度对回收率没有影响.该方法不仅对病毒的回收率高（＞80%）,且浓集污水量较大（20 L）、效果稳定.

英文摘要：

An enteric virus concentration method from sewage is introduced. In the method, an electropositive material （poly-aluminum chloride） was added into the sewage before the virus concentration. The recovery of the f2 phage can reach to （92.06± 8.65 ） % under an addition of 30 mg/L polyaluminum chloride and reach to （92.15±6.02）% at pH 6.5. Temperature has no influence on the virus recovery. The method is efficient and steady in virus recovery, and can be used to concentrate large volume sewage （20 L）.
