城中村是我国城市化进程中阶段性的产物,建筑密度大、楼宇建筑不规整,供排水系统存在较多薄弱节点.对典型城中村供排水系统存在的问题进行分析梳理,明确致病微生物在街区供排水系统中潜在传播途径及关键节点,构建供排水系统面向生物风险防控需求的"建筑、社区、街区"多层级应急响应体系防控措施,期望为保障城中村卫生安全提供理论支撑.
Urban villages are a phased product of China's urbanization process,with high building density,irregular buildings,and many weak nodes in the water supply and drainage system.Analyze and sort out the problems existing in the water supply and drainage system of typical urban villages,clarify the potential transmission pathways and key nodes of pathogenic microorganisms in the block water supply and drainage system,and construct a multi-level emergency response system prevention and control measures for buildings,communities,and blocks in the water supply and drainage system to meet the needs of biological risk prevention and control.It is expected to provide theoretical support for ensuring the health and safety of urban villages.
