Safety Risks&Biological Pollution Control Measures for Urban Village Water Supply&Drainage Systems
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.
