口腔综合治疗台供水水源对管路内部水质的影响研究

摘要

Objective To investigate the impacts of water supply on water quality in the pipeline of the dental comprehensive treatment platform to contribute to pollution control.Methods Totally 8 platforms from the stomatological department underwent 2-a detection and tracing.The water sources included tap water,distilled water and filtered water,and the discharge water went through sampling and bacteriological analysis before and after disinfection.Results The mean numbers of colonies by tap water,distilled water and filtered water were (472±385),(380±372) and (446±382) cfu/ml respectively,and the qualification rates by tap water,distilled water and filtered water were 33.3％,45.8％ and 37.5％ respectively.All the colonies numbers were limited within 0 and 60 cfu/ml with the qualification rate being 100％ after disinfection.Conclusion Water source cannot relieve bacterial infection effectively,and disinfection eliminates bacteria and improves water quality in the pipeline of the dental comprehensive treatment platform.%目的:研究口腔综合治疗台供水水源对管路内部水质的影响,为其控制污染提供依据.方法:通过对口腔科8台牙科综合治疗台连续2a的检测跟踪,采用自来水、蒸馏水、过滤软化水3种供水方式,对消毒前和消毒后的治疗台手机出水进行采样,分别进行细菌学检测.结果:在自来水、蒸馏水、过滤软化水这3种供水方式下,治疗台手机出水端采集的水样经培养检测后的细菌茵落数平均值分别为(472±385)(合格率33.3％)、(380±372)(合格率45.8％)、(446±382)cfu/ml(合格率37.5％);对内部管路消毒后,检测的细菌菌落数在0～60 cfu/ml范围内(合格率100％).结论:选择不同的供水方式不能有效地降低治疗台内部的细菌污染,只有通过消毒手段才能有效地清除细菌,改善治疗台内部用水管路的污染状况.
