地表水致病微生物的污染特征与处理技术研究

Research on Pollution Characteristics and Treatment Technology of Pathogenic Microorganisms in Surface Water

隐孢子虫与贾第鞭毛虫(简称"两虫")作为典型致病微生物,是导致人体腹泻的水源性原生动物寄生虫。两虫具有抗性强、个体小、感染范围广、发病率高等特点,目前尚无有效治疗的药物。常规的水处理工艺不能去除和灭活两虫,需创新技术来有效完善处理工艺。其中,臭氧灭活、紫外线消毒均有较好效果;多种消毒剂联合作用的方法,提高两虫的灭活率,达到较好的灭活效果。

Cryptosporidium and Giardia（referred to as ＂two insects＂） for the typical pathogenic microorganisms, is the cause of human diarrhea, waterborne protozoan parasites. These two insects have the characteristics of strong resistance, individual small, wide range of infection, high incidence, and there is no effective treatment of drugs. Conventional water treatment process cannot remove and inactivate them, and we need innovative technology to effectively improve the treatment process. Ozone inactivation, UV disinfection have a better effect; a variety of disinfectant combination of methods, can also greatly improve the rate to achieve better inactivation effect.
