2010-2015年金堂县农村学校自备水卫生监测结果分析

Retrospective Analysis on Sanitary Surveillance Results of Self-prepared Water in Rural Schools in Jintang County,2010-2015

目的分析金堂县农村学校自备水水质卫生情况,为政府决策提供依据。方法收集金堂县2010~2015年学校自备水水质检测报告,分析各年份和检测指标的合格率。结果 2010-2015年学校自备水水质总合格率为59.48%,逐年依次为28.26%、23.66%、62.77%、75.29%、87.21%和72.72%,合格率的差异具有统计学意义(χ~2=102.93,P=0.00);幼儿园61.21%,小学58.86%,中学55.34%,合格率的差异不具有统计学意义(χ2~=0.98,P=0.61);不合格的检测指标主要为菌落总数、总大肠菌群、大肠埃希菌群、总硬度、硝酸盐。结论金堂县农村学校自备水合格率较低,需通过加强水质监测和管理力度,实施管网水工程覆盖,可长期有效地保证农村学校自备水水质质量。

Objective To analyze sanitation of self - prepared water in rural schools in Jintang County and provide a scientific basis for the government departments in decision making. Methods Quality test reports of self - pre- pared water in schools in Jintang in 2010 - 2015 were collected and the conformity rates of test indicates in each year were analyzed. Results The total conformity rate of self - prepared water in schools in 2010 - 2015 was 59.8% ; the conformity rates from 2010 to 2015 were 28.26%, 23.66%, 62. 77% , 75.29% , 87.21% and 72.72% , respectively; the differences were statistically significant （X2 = 102.93, P =0. 00）. The conformity rates in kindergartons, primary schools and middle schools were 61.21% , 58.86% and 55.34% , respective- ly; the differences were not statistically significant （X2 = 0.98, P = 0.61 ）. Non -conforming test indicators mainly included total number of colonies, total coliforms, Escherichia coli, total hardness and nitrate. Conclu- sion The conformity rate of self - prepared water in rural schools is low ; water quality surveillance and manage- ment should be enhanced, and the water- supply pipeline enginering should be fully implemented so as to el- fectively ensure quality of self - prepared water in rural schools.
