一、消毒的目的与必要性为了保障人民身体健康,防止水致传染病的传播,生活饮用水中不应含有病原微生物。我国生活饮用水水质标准规定:在37℃培养24小时的水样中,细菌总数不应超过100个/毫升,大肠菌群不应超过3个/升。消毒就是杀灭水中病原微生物、保证安全水质的最后一关,这对于贯彻“预防为主”的方针起着重要作用。天然的地面水一般都是经过雨水的冲刷汇流,受到各种杂质的污染,是很不卫生的。经过慢滤池过滤
First, the purpose and necessity of disinfection In order to protect people’s health and prevent the spread of water-borne diseases, drinking water should not contain pathogenic microorganisms. China drinking water quality standards: 37 ℃ cultured in 24 hours of water samples, the total number of bacteria should not exceed 100 / ml, coliform bacteria should not exceed 3 / liter. Disinfection is to kill the pathogenic microorganisms in the water, to ensure the safety of the last level of water quality, which for the implementation of “prevention first” approach plays an important role. Natural surface water is generally washed through the convergence of rain, by a variety of impurities in the pollution is very unsanitary. After slow filter filter
