中文摘要： 长期以来，我国城镇污水处理系统主要集中于污水中有机物与氮磷的去除，对于病原微生物的研究十分有限，对排水系统中的病原微生物在受纳水体中的分布、迁移及灭活的研究更为缺乏。为了降低以非常规水源补给为主的典型河流在公共卫生安全方面的风险，本研究以海河流域为主要研究对象，系统考察病原微生物在该区域永定河（张家口市段）- 温榆河（北京段）- 北运河（天津段）的污染状况，考察环境因子和河流水文特征对河流病原微生物传输、分布的影响，探明河流病原微生物污染的来源、传输途径和归趋。本研究从河流病原微生物污染传输途径的关键环节（污染源-传输-河流）入手，系统的研究河流病原微生物污染发生机理和传输机理以及控制技术，以实地监测数据为基础进行微生物污染的健康风险分析，探索河流病原微生物污染控制的最佳途径和方式，为我国河流病原微生物污染控制提供科学的决策依据。

英文摘要： Rivers and streams are usually fed by surface runoff and baseflow. However the non-conventional contributions from reclaimed water and distributed wastewater discharge have been increasing over the last decades in north China. Rivers and streams within Haihe basin will be fed primarily by reclaimed water and distributed wastewater discharge. Municipal wastewater treatment usually focuses on the removal of organic pollutants and nutrients. Literature has paid little attention on the distribution, transpose, and fate of waterborne pathogenic microorganisms. It is of extreme importance for public health and welfare to analyze and characterize pathogenic microorganism pollution in the nonconventional rivers and streams. This study systematically investigates distribution, transport, and fate of waterborne pathogenic organisms in Yongdinghe River (Zhangjiakou) -Wenyuhe River (Beijing) -Beiyuhe River (Tianjin). This study focus the key path of pollutions source - transport - river and identifies the typical engineering technology and measures. This study will characterize the distribution, transport, and fate of waterborne pathogenic microorganism in nonconventional rivers and streams in northern China and will explore the best available engineering technologies to control pathogenic microorganisms pollution. Environmental health risk will be analyzed and assessed. The study will provide valuable and sound scientific basis for pollution control for nonconventional rivers and streams.
