2017年新疆维吾尔自治区生活饮用水现状及影响因素分析

Current Situation and Influencing Factors of Drinking Water in Xinjiang in 2017

摘要

摘要:
目的了解2017年新疆维吾尔自治区生活饮用水卫生监测现状，分析水质的影响因素。
方法全疆2017年共采集监测点水样出厂水样6 160份，进行水质检测分析。水样的采集、保存和分析，均按照《生活饮用水标准检验方法》（GB 5750-2006）进行；采用《生活饮用水卫生标准》（GB 5749-2006）对水样进行评价，有1个指标不合格即判定该水样为不合格。采用χ²检验和Logistic回归进行单因素和多因素分析。
结果 2017年新疆生活饮用水合格率为62.4%。区域划分为北疆（OR=0.523，95% CI：0.466~0.588）和东疆（OR=0.552，95% CI：0.442~0.690）、水样类型为末梢水（OR=0.874，95% CI：0.776~0.984）、二次供水（OR=0.542，95% CI：0.442~0.690）；水源类型为地下水（OR=0.445，95% CI：0.393~0.505）、供水方式为经处理（OR=0.763，95% CI：0.679~0.859）是生活饮用水水质的保护因素，采样类型为农村（OR=1.522，95% CI：1.343~1.724）是生活饮用水水质的危险因素。
结论通过改水防病工作，居民饮水质量得到明显提高，但水质合格率仍偏低，供水方式、水源类型和地理环境是影响新疆生活饮用水水质的重要因素。

Abstract:
Objectives To investigate the current situation of drinking water in 2017 and analyze the influencing factors of water quality.
Methods A total of 6 160 water samples collected from monitoring stations in Xinjiang were analyzed according to the Standard Examination Method for Drinking Water (GB 5750-2006), detected and evaluated according to the Standard for Drinking Water Quality (GB 5749-2006). If any one of the indicators did not reach the standard, the water sample would be judged as unqualified. The test of χ² and Logistic regression were used for univariate and multivariate analysis.
Results The total qualified rate of drinking water samples was 62.4%. The result of Logistic regression analysis showed that the water samples collected from northern Xinjiang(OR=0.523, 95% CI:0.466~0.588) or eastern Xinjiang(OR=0.552, 95%CI:0.442~0.690), underground water(OR=0.445, 95% CI:0.393~0.505) and completely treated water(OR=0.763, 95%CI:0.679~0.859) were protective factors; but from rural area(OR=1.522, 95%CI:1.343~1.724) was a risk factor.
Conclusions The quality of drinking water was significantly better after implementing water improvement projects and disease prevention works, however the quality of drinking water was still low. The forms of water source, types of water supply and geographical environment are important factors affecting the quality of drinking water in Xinjiang.
