摘要
我国每年产生大量医院污水,其中包含病原体等多种污染物,是危害人类健康的重要隐患.目前对医院污水的处理主要包括污水的预处理、生物处理和消毒三部分.通过采用活性污泥法、生物接触氧化法、膜生物反应器、曝气生物滤池法等环境微生物技术对污水进行处理,从而有效去除水中的有机物,破坏病原微生物赖以生存的物质基础和保障消毒效果.不同的处理工艺各有优缺,适合于不同规模的医院.
Plenty of hospital sewage is produced in China every year, which contains various pollutants, especially pathogen. So it is a potential threat to human health. Hospital sewage treatment process includes pretreatment,biological treatment and disinfection. By using of activated sludge process,biological contact oxidation process, membrane bioreactor, biological aeration filter and other environmental microbiological technologies,people could remove organic compounds effectively in water, destroy the material base that pathogenic microorganisms depend on for existence, and ensure disinfection effect. Every treatment technology has different characteristics and snitable for different scale hospitals.
