对住区污水再生利用水源、利用途径及健康危害进行分析,得出以住区污水为水源的再生水,主要考虑病原微生物的健康风险。概述了再生水中病原体微生物对人体健康影响的评价方法——现实风险评价方法和定量风险评价。提出应用风险评价方法研究来制订住区污水再生利用标准和规范,并通过开发高效、节能、易管理的先进处理技术和设备、加强运行管理和水质监测等方面来促进污水资源化利用。
By analyzing the water sources, utilization ways and health hazards of the reclaimed sewage in residential areas, the reclaimed water with sewage in the settlements as the water source is obtained, mainly considering the health risks of the pathogenic microorganisms. The methods to evaluate the influence of pathogenic microorganisms in human reproductive water on human health are summarized - the real risk assessment method and the quantitative risk assessment. This paper puts forward the application of risk assessment method to formulate standards and norms for the reclamation and utilization of sewage in settlements and to promote the utilization of wastewater by developing advanced treatment technologies and equipment that are efficient, energy saving and easy to manage, and strengthening operation management and water quality monitoring.
