中文摘要：

采用荧光微球模拟隐孢子虫和贾第鞭毛虫（简称两虫）,考察了有机物和颗粒物的浓度、组成等水质特性对污水再生处理絮凝工艺中两虫去除特性的影响.结果表明,腐殖酸浓度增加可提高水样中胶体浓度,从而提高对两虫的去除率;而酪氨酸虽然能改变胶体表面性质,但不参与絮凝过程,故对两虫的去除率无明显影响.水样初始浊度对两虫去除率影响较小;但水样中颗粒物的粒径分布,特别是1nm-100μm粒子的比例与对两虫去除效果间存在较好的相关关系.

英文摘要：

The influence of water quality characters such as the concentration and composition of organic and particle materials on the removal character of two insects in wastewater regenerated treating flocculation technique was inspected, adopting fluor-microball to simulate Cryptosporidium and Giardia （abbreviated two insects）. Increase of humic acid concentration could raise colloid concentration in water sample, thus raised the removal rate of two insects; while tyrosine although could change the colloid surface property but did not participate in the flocculation process, therefore without obvious influence on the removal rate of two insects. The initials turbidity of water sample influence less on the removal rate of microball; but the diameter distribution of particle material in water sample, especially the proportion of 1nm-100μm particle existed better correlation with the removal effect of two insects.
