【摘要】：为了解家用净水设备出水细菌污染状况及影响因素,于2015年10月—2016年5月入户调查并采样检测天津52户净水设备用户自来水及净水设备出水的微生物指标并鉴定菌种。结果显示,28.8%的净水设备出水菌落总数超标,1台净水设备出水总大肠菌群超标。2台净水设备出水检出蜡样芽胞杆菌,1台净水设备出水检出金黄色葡萄球菌,其他净水设备出水检出克氏库克菌及人苍白杆菌等条件致病菌。提示家用净水设备出水细菌污染状况应受到重视,应定期更换滤芯,避免细菌污染。
[Abstract]:In order to understand the status of bacterial contamination in the effluent of household water purification equipment and its influencing factors, a survey was conducted from October 2015 to May 2016, and the microbiological indexes of tap water and effluent of water purification equipment of 52 households of water purification equipment in Tianjin were investigated and tested, and the bacteria species were identified. The results showed that the total number of bacteria in the effluent of 28. 8% of the water purification equipment was above the standard. The total coliform bacteria in the effluent of 1 water purification plant exceeded the standard. 2. 2 sets of water purification equipment detected Bacillus cereus and 1 water purification equipment. Staphylococcus aureus was detected in the effluent of the water purification equipment. Other water purification equipment water detection of Cook's bacteria and human alcaligenes and other conditional pathogens. It is suggested that attention should be paid to the bacterial contamination in the effluent of household water purification equipment and the filter element should be changed regularly to avoid bacterial contamination.
