某老年医院废水处理工艺设计探析

Design of wastewater treatment process in an geriatric hospital

由于成分的复杂性和特殊性,医院废水需要经过一定处理后进行排放。根据某老年医院的排水情况、水质成分和处理标准,选择二级生化工艺进行废水处理。在此探析该工艺的特点、运行原理和设计参数。该工艺中生活污水和医疗废水采用“生物接触氧化法+消毒”处理达标后,排入市政污水管网,特殊废水采取单独预处理方式。根据计算,处理后的水质到达相关标准的水质要求。此工艺简单,能在最大程度上实现废水减量化、无害化。

Hospital wastewater needs to be discharged after a certain treatment because of the complexity and particularity of the ingredients.According to the drainage situation,water quality composition and treatment standards of a geriatric hospital,a secondary biochemical process was selected for wastewater treatment.The characteristics,operation principles,and design parameters of this process are hereby analyzed.In this process,domestic sewage and medical wastewater are treated by"bio-contact oxidation+disinfection",and then enter the municipal sewage pipe network,special wastewater was pretreated separately.According to calculations,the quality of the treated water can meet the water quality requirements of the related standards.This process was relatively simple and can reduce the waste water and make it harmless.
