目的了解北京市石景山区游泳场所水质卫生状况,保护游泳者的身体健康,为行政监管提供科学依据。方法 2014年1月、5~10月,对石景山区全部游泳场所进行监测,每月监测1次,每次采集3件池水样品,监测项目为水温、游离性余氯、浑浊度、p H值、尿素、细菌总数、大肠菌群共计7项指标,检测依据为GB 18204-2000和GB/T 5749-2006。结果 2014年共监测水样255件,合格率为7.06%;主要不合格项目为游离性余氯、水温、尿素,其合格率分别为18.82%、48.63%、57.25%,细菌总数、p H值的合格率分别为96.86%、98.82%,浑浊度和大肠菌群100%合格。学校内设游泳池的游离性余氯、尿素和全项的合格率高于独立游泳馆和宾馆内设游泳池,但差异无统计学意义。不同月份的游离性余氯、尿素合格率变化不大(50.00%~58.33%);水温合格率6—8月较低(27.78%~35.71%),1、5、9月次低(54.54%~58.33%),10月最高为100%,经χ2检验各月份合格率差异有统计学意义(χ2=49.372,P<0.01)。结论该区游泳场所卫生状况欠佳,需加强卫生管理,确保各项指标值维持在标准范围内。
Objective To understand the water quality and sanitation of swimming places in Shijingshan District of Beijing, protect the health of swimmers and provide a scientific basis for administrative supervision. Methods From January to May 2014, all the swimming places in Shijingshan District were monitored and monitored monthly. Three samples of water samples were collected each time. The monitored items were water temperature, free residual chlorine, turbidity, p H value , Urea, total bacteria, coliform total of seven indicators, testing is based on GB 18204-2000 and GB / T 5749-2006. Results A total of 255 water samples were monitored in 2014, with a pass rate of 7.06%. The main unqualified items were free residual chlorine, water temperature and urea. The pass rates were 18.82%, 48.63% and 57.25%, respectively. The total number of bacteria, p H value The pass rate was 96.86%, 98.82%, turbidity and coliform 100% qualified. Free chlorine, urea and all the qualified rate of the swimming pool in the school is higher than that of the independent swimming pool and swimming pool in the hotel, but the difference is not statistically significant. The percentages of free chlorine and urea in different months did not change much (50.00% -58.33%); the qualified rate of water temperature was low in June-August (27.78% -35.71%), low (54.54% ~ 58.33%), the highest in October was 100%. There was a significant difference in pass rates between each month (χ2 = 49.372, P <0.01) by χ2 test. Conclusion The sanitary conditions in the swimming area in this area are not good. Health management should be strengthened so as to ensure that the index values remain within the standard range.
