Abstract: The safety of drinking water quality is directly related to public health and social stability, and microbial contamination is oneof the core issues threatening water quality safety.This article analyzes the main sources of microbial contamination in drinking water, including water source polltion, water treatment process pollution and secondary water supply polution,and proposes prevention and control measures centered on water source protection,process optimizationand pipe network management,aiming tobuild a multi-level,full-process microbial contamination prevention and control system.
Keywords: drinking water; water quality safety; microbial contamination; water supply network management
隨著工業化、城市化進程的加速,人類活動對水環境的干擾日益加劇。大量工業廢水、生活污水未經妥善處理便排入自然水體,導致水源地遭受不同程度的污染,微生物污染問題愈發嚴峻。微生物污染不僅威脅人體健康,可能引發腹瀉、傷寒等疾病,還會對社會經濟造成負面影響,如增加醫療成本、影響生產活動。在此背景下,深人探究生活飲用水水質安全控制中微生物污染的防治措施,具有重要現實意義。
1保障生活飲用水水質安全的意義
保障生活飲用水水質安全具有重要意義。從人體健康層面看,保障飲用水安全是維持身體正常代謝的基礎,可有效避免因微生物污染引發的各類疾病,如傷寒、霍亂等腸道傳染病,守護公眾身體健康[1]。在社會民生領域,飲用水供應安全是居民安居樂業的保障,關乎社會和諧穩定。若水質出現問題,易引發公眾恐慌,影響社會秩序。在經濟層面,保障生活飲用水安全還能減少因疾病導致的醫療開支增加,同時助力餐飲、食品加工等依賴飲用水的行業穩健發展,促進經濟繁榮。
2生活飲用水中微生物污染的主要來源
2.1水源地污染
水源地作為生活飲用水的源頭,其水質直接關系到千家萬戶的用水安全。在眾多污染源中,農業活動對水源微生物污染影響顯著。集約化畜禽養殖規模龐大,產生的大量糞便廢水若未經有效處理就排入周邊水體,會導致大腸桿菌、沙門氏菌等多種病原微生物在水源地擴散。……
