我国水资源短缺已引起各方高度重视,而水 源水质污染严重,有可能危及城市给水安全,更 应引起国家有关部门的密切注视和高度关注。 过去因为水源比较清洁,污染较小,水工作者 主要的任务是去除水中浊度与细菌病毒,但经过几 十年的发展,水源已受到各种各样不同程度的污染。 目前水源水质污染主要是有机物污染,内分泌 干扰物污染,汽油中添加剂的替代物、藻毒素、抗 生素和纳米材料等有机污染物以及微生物污染等。 有机物的人工合成,方便了人们的生活,促 进了社会发展。但由于生产、使用与废弃等过程 不当,已经对环境造成了污染,引发环境安全危 机。它们通过食物链又进入人休,对人类产生种 种危害与潜在威胁。
The shortage of water resources in our country has drawn great attention from all parties, and the water quality of the water sources is seriously polluted, which may endanger the safety of urban water supply. It should even be closely watched and highly concerned by the relevant state departments. In the past, water sources were relatively clean and polluted. The main task of water workers was to remove turbidity and bacterial viruses in water. However, after decades of development, water sources have been polluted to varying degrees. At present, water pollution is mainly caused by organic pollutants, endocrine disrupting chemicals, substitutes for gasoline additives, organic pollutants such as algal toxins, antibiotics and nanomaterials, and microbial contamination. Artificial synthesis of organic matter, to facilitate people’s lives and promote social development. However, due to improper processes such as production, use and disposal, it has caused environmental pollution and triggered an environmental crisis. They enter the rest of the world through the food chain and pose a variety of hazards and potential threats to humanity.
