微生物技术在医疗废水处理中的应用

医院污水含有多种病菌、病毒及寄生虫，其直接危害和潜在危害都是显而易见的，因此，进行医疗废水治理，已成为当务之急。微生物处理主要是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。

Application of microbiological technology on hospital sewage treatment

China produces a large number of hospital sewage every year, containing a variety of bacteria, viruses and parasites, which direct damage and potential hazards are obvious. Therefore, it becomes first imperative for medical waste water treatment. Micro- bial treatment is the way of sewage treatment mainly through the use of activated sludge, biological contact oxidation and membrane bioreactor. So as to remove the organic matter in the water effectively, and destroy pathogenic microorganisms in the material basis for survival and protection of disinfection. Different treatment processes suitable for hospitals of different sizes.
