摘　　要：目的了解2019年黑龙江省学校生活饮用水水质的卫生状况,对影响水质的因素进行分析。方法通过监测系统收集黑龙江省13个市(地)上报的学校生活饮用水水质监测的随机抽检结果,采用流行病学研究方法进行分析。结果检查的112所学校中,自建设施集中供水水质检测结果显示,色度、浑浊度、臭和味、肉眼可见物、pH值、消毒剂余量、全部六项指标合格率分别为98.1%、98.1%、98.1%、98.1%、98.1%、38.9%和74.1%;二次供水水质检测结果显示,色度、浑浊度、臭和味、肉眼可见物、pH值、消毒剂余量、全部六项指标合格率分别为84.5%、84.5%、84.5%、84.5%、82.8%、72.4%和81.0%。结论城区水质情况明显好于农村,不同供水方式均对水质有影响。应改善农村学校饮用水水质状况,卫生健康、教育等部门应加强联合检查,从而保障师生的饮水安全。Objective To know the sanitary condition of drinking water quality monitoring in Heilongjiang Province in2019, and to investigate the factors affecting the water quality. Methods The drinking water quality of 13 prefectures and cities in Heilongjiang Province was monitored and sampled by random supervision. Epidemiologic study method was used. Results Among 112 inspected schools, the water quality test results of the self-built facilities showed that color,turbidity, odor and taste, naked eye visible matter, pH, disinfection allowance and total six indexes were 98.1%, 98.1%,98.1%, 98.1%, 98.1%, 38.9% and 74.1%. Secondary water supply water quality test results showed that pass rates of color turbidity, odor and taste, naked eye visible matter, pH, disinfectant allowance and total six indexes were 84.5%,84.5%, 84.5%, 84.5%, 82.8%, 72.4% and 81.0%, respectively. Conclusion The water quality in urban areas is obviously better than that in rural areas, and different water supply modes have influence on water quality. It is suggested to improve the quality of drinking water in rural school, strengthen joint inspections by departments of health and education, and ensure the safety of drinking water for teachers and students.
