医院污水处理方法应用进展

Application Progress of Hospital Wastewater Treatment Methods

目的医院污水的处理越来越受到人们的重视,医院污水处理方法主要有生物学方法、物理方法和化学方法。生物学方法包括简易生化处理、活性污泥法、生物接触氧化法、膜生物反应器、曝气生物滤池等,是环境微生物技术在处理医院污水方面的具体应用。物理方法主要用于污水的预处理和消毒,如紫外线消毒法。化学方法主要用于消毒,包括氯消毒法、臭氧消毒法、电化学法以及光触媒技术的应用。应根据医院的类型、规模、总污水量和污水性质,明确污水来源,选择合理、有效的处理工艺,保证医院污水得到有效处理,使出水水质符合现行有关国家排放标准的规定。

[Objectives]People are attaching more and more importance to the hospital wastewater treatments,the hospital wastewater treatment methods mainly are biological methods,physical methods and chemical methods.Biological methods are the specific application of environmental microbial technology in the processing of hospital wastewater,which include simple biological treatment,activated sludge method,biological contact oxidation method,membrane bioreactor and biological aerated filter.Chemical methods,take ultraviolet disinfection for example,are mainly used for pre-treatment and disinfection of wastewater.Chemical methods are mainly applied to disinfection,including chlorine disinfection,ozone disinfection electrochemical method and the photocatalyst technology.According to the type and size of hospital,total amount and character of wastewater,we should clarify the source of wastewater and choose rational and effective treatment process,so as to ensure effective treatment for hospital wastewater,and guarantee effluent water quality in accordance with national emission standards.
