医疗机构的污水是一种特殊的污水,含有很多病毒、病菌和有毒、有害物质,具有极大的危害性,如果不进行消毒处理直接排放,就会成为病原菌扩散的重要途径,严重污染环境,甚至引起多种传染性疾病的发生和流行,严重危害人民群众的身体健康。为了解该市二级及以下医疗机构污水处理情况,2017年6—9月对西安市13个区县的198家二级及以下医疗机构的污水排放量、污水处理进行调查。

3 讨论
根据国家环保总局和国家质量监督检验检疫总局发布的《医疗机构水污染排放标准》(GB 18466-2005),凡从事疾病诊断、治疗活动的医院、卫生院、疗养院、门诊部、诊所、卫生急救站等都是医疗机构;而从医疗机构门诊、病房、手术室、各类检验室、病例解剖室、放射室、洗衣房、太平间等处排除的诊疗、生活及粪便污水都是医疗机构的污水。为防止病原微生物二次污染,不同的医疗机构需要遵循不同的排放标准。本次调查显示,西安市二级及以下医疗机构的污水排放还存在很多问题,医疗机构对医疗污水处理工作不够重视,尤其是二级以下医疗机构,大部分医疗机构对医疗污水不进行处理,直接排放;且二级及以下医疗机构对污水处理的监测也不够,不能确保消毒后的污水能否达标排放。因此,建议监管部门和监测部门加大监督检测力度,尤其是二级及以下医疗机构医疗污水排放情况,按照《医疗机构污水污染物排放标准》(GB 18466-2005)要求,对污水排放不合格的医疗机构进行定期、不定期的监测,落实污水消毒处理措施,确保达标排放。
