目的了解不同水源水与水质工艺处理方式对饮用水水质的影响。方法按不同源水来源与处理工艺在辖区内设置生活饮用水采样点37个,每月采样检测,共采集水样408件。结果黄浦江源水生活饮用水水质检测总合格率为74.85%,青草沙水库源水的水质检测总合格率为97.47%,二者差异有统计学意义(χ2=48.07;P<0.05)。黄浦江源水经深度处理后,生活饮用水水质检测总合格率为83.08%,常规处理水质总合格率仅为48.78%,二者差异有统计学意义(χ2=19.48;P<0.05);青草沙水库源水经2种不同工艺处理后,水质没有明显差异。结论水质以青草沙水库为源水的优于黄浦江源水。源水与处理工艺决定水质的优劣,应逐步选用优质源水和深度处理工艺,去除水中有机物的污染,有效提高水质质量。
Objective To understand the influence of different source water and water treatment methods on drinking water quality. Methods According to different sources of source water and treatment process, 37 drinking water sampling points were set up in the area under their jurisdiction, and monthly sampling and testing were carried out. A total of 408 water samples were collected. Results The total qualified rate of drinking water quality of Huangpu River source water was 74.85%. The total qualified rate of water quality of Qingcaosha reservoir source water was 97.47%. The difference was statistically significant (χ2 = 48.07; P <0.05). The total qualification rate of drinking water quality in the Huangpu River after deep treatment was 83.08%, and the total pass rate of routine treatment water quality was only 48.78%, the difference was statistically significant (χ2 = 19.48; P <0.05) There was no significant difference in water quality after the sand source water was treated by two different technologies. Conclusion The water quality of Qingcaosha Reservoir is better than that of Huangpu River source water. Source water and treatment process determines the quality of the water quality should be gradually selected high-quality source of water and advanced treatment technology to remove organic pollution in water, effectively improve water quality.
