新乡市新冠肺炎疫情期间医疗废水余氯监测

Monitoring Residual Chlorine in Medical Wastewater during the COVID-19 Epidemic in Xinxiang City

以新乡市新冠肺炎期间定点医院医疗废水余氯含量应急监测为例,自2020年2月2日起连续9轮测定医院医疗废水和城镇污水处理厂出水的余氯含量。比较分析了沃特检测管法和哈希DPD法的一致性,说明两种应急监测方法对余氯的监测数据无显著性差异。通过对余氯含量应急监测数据的分析,指出了医疗废水余氯监测存在医疗单位污水处理设施简陋、消毒剂随意投放等问题,并提出了加强医疗单位污水处理设施管理的建议,以确保医疗废水余氯浓度符合相关标准。

The residual chlorine content in hospital wastewater and the effluent from town sewage treatment was determined for 9 consecutive rounds since February 2,taking the emergency monitoring of the residual chlorine content in hospital wastewater during the period of COVID-19 in Xinxiang as an example.The consistency of Wort detection tube method and hashing DPD method were compared,which shows that there is no significant difference in residual chlorine monitoring data between the two emergency monitoring methods.Based on the analysis of the emergency monitoring data of residual chlorine content,this paper pointed out the problems of the crude sewage treatment facilities in medical units and the random distribution of disinfectants,and put forward four suggestions for strengthening the management of sewage treatment facilities in medical units,to ensure that residual chlorine in medical waste water meets relevant standards.
