【摘要】：目的为了解泰安市不同类别机构污水处置及消毒情况,防止污水中病原体及化学性有害物质污染周围环境。方法通过现场调查和不同机构污水采样。抽检全市23家有污水处理能力的医疗机构排放的污水,按GB 18466-2005《医疗机构水污染物排放标准》的要求进行阴离子表面活性剂、色度、p H值、氨氮、挥发酚、总氰化物、总汞、总镉、六价铬、总砷、总铅、总余氯、沙门菌、粪大肠菌群数和志贺氏菌等15项指标的卫生学检测。结果氨氮、挥发酚、总氰化物、总汞、总镉、六价铬、总砷、总铅、总余氯、沙门菌和志贺氏菌10项指标合格率均为100%,总余氯合格率为69.57%,粪大肠菌群合格率为91.30%,色度合格率为86.96%,阴离子表面活性剂格率为95.65%,PH值合格率为91.30%。结论不同级别医疗机构污水消毒处理存在差异,总余氯合格率最低,存在过量使用含氯消毒剂,大部分机构都配备污水处理设备,但都处于不运行状态,需进一步扩大抽检监测工作,确保不同机构污水安全排放。
[Abstract]:Objective to understand the situation of sewage disposal and disinfection in different organizations in Taian City, and to prevent pathogens and chemical harmful substances from polluting the environment. Methods through field investigation and sewage sampling of different organizations. The sewage discharged from 23 medical institutions with sewage treatment capacity in the city was sampled and tested. According to the requirements of GB 18466-2005, the anionic surfactant, chroma pH value, ammonia nitrogen, volatile phenol, total cyanide, total mercury, etc., were carried out according to the requirements of GB 18466-2005. Total cadmium, hexavalent chromium, total arsenic, total lead, total residual chlorine, salmonella, fecal coliform group and Shigella. Results ammonia nitrogen, volatile phenol, total cyanide, total mercury, total cadmium, hexavalent chromium, total arsenic, total lead, total residual chlorine, The qualified rates of 10 indexes of Salmonella and Shigella were 100, the qualified rate of total residual chlorine was 69.57, the qualified rate of fecal coliform was 91.30, the qualified rate of coliform was 86.96, the qualified rate of anionic surfactant was 95.65 and PH value was 91.30. Conclusion there are differences in disinfection treatment of sewage in different medical institutions, the qualified rate of total residual chlorine is the lowest, there is excessive use of chlorine containing disinfectant, and most of the institutions are equipped with sewage treatment equipment, but all of them are not in the state of operation. It is necessary to further expand the work of spot inspection and monitoring to ensure the safe discharge of sewage from different organizations.
