Water quality analysis before and after advanced treatment of source water in a water plant XUAN Guoꎬ XU Ming ̄jiaꎬ LI Weiꎬ JIN Hui(Jinshan Center for Disease Control and Preventionꎬ Shanghai 201599ꎬ China) Abstract: [ Objective] To investigate the changes of the quality of drinking water before and after advanced treatment of source water in a water plantꎬ so as to provide the scientific evidence for management of the quality of drinking water. [ Methods] The tap water and the same as drinking water were monitored and studied before and after advanced treatment. [ Results] The comprehensive qualified rate of source water before and after advanced treatment were 81������ 7% and 80������ 0% respectivelyꎬ with no significant difference. The comprehensive qualified rates of the factory water and the end water before and after advanced treat ̄ ment were 50������ 6% and 99������ 4%ꎬ respectivelyꎬ with significant differences between the two conditions. The qualified rates of individual water quality indicators of the tap water and the end water before and after the advanced treatment were as follows: the oxygen consumption was 58������ 3%ꎬ 100%ꎬ the turbidity 92������ 2%ꎬ 100%ꎬ the manganese 90������ 0%ꎬ 100%ꎬ the total bacterial counts were 96������ 7% and 99������ 4% respectivelyꎬ the difference was statistically significant( P<0������ 05) ꎻ the total coliform groups were 98������ 3%ꎬ 100%ꎬ the difference being without statistical significance. [ Conclusion] The water quality of the area has been greatly improved after advanced treatmentꎻ greater emphasis should be given to the index of microorganism and the hygiene of drinking water is further monitored. Keywords: drinking waterꎻ advanced treatmentꎻ oxygen consumptionꎻ health monitoring
