为探讨宁夏城市饮水微生物学指标合格率与介水传染性疾病发病的相关性,于2011—2013年对宁夏城市698个末梢水监测点水样中的菌落总数、总大肠菌群和耐热大肠菌群进行检测,并收集同时期介水传染性疾病的发病情况。结果显示,共检测末梢水水样1 395件,菌落总数、总大肠菌群和耐热大肠菌群合格率分别为88.66%,93.87%和95.75%;市政供水、城市自建集中式供水、二次供水菌落总数分别为95.41%,89.92%和80.65%。末梢水中菌落总数的合格率与感染性腹泻、细菌性痢疾发病数均呈负相关(P<0.05);总大肠菌群的合格率与感染性腹泻、细菌性痢疾、甲肝发病数均呈负相关(P<0.05)。提示微生物学指标与宁夏城市介水传染性疾病发病有一定关联。
In order to explore the correlation between the passing rate of microbiological indicators of drinking water in Ningxia and the incidence of water-borne infectious diseases, the total number of colony, total coliforms and heat-resistant large intestine in water samples of 698 peripheral water monitoring points in Ningxia City from 2011 to 2013 Detection of flora, and collect the same period the incidence of water-borne infectious diseases. The results showed that a total of 1 395 samples of peripheral water were detected, the total number of colonies, total coliform and heat-resistant coliform bacteria were 88.66%, 93.87% and 95.75% respectively. Municipal water supply and urban self-built centralized water supply, The total number of secondary water supply was 95.41%, 89.92% and 80.65% respectively. There was a negative correlation between the passing rate of total colony in peripheral water and the number of infectious diarrhea and bacillary dysentery (P <0.05). The passing rate of total coliforms was negatively correlated with the number of infectious diarrhea, bacillary dysentery and hepatitis A (P <0.05). Prompted microbiological indicators and Ningxia City, the incidence of water-borne diseases have a certain relationship.
