摘要:
针对长距离输水过程中供水水质安全问题，以JZ水库至SP原水厂之间的原水输送管道（约40 km） 为研究对象，分析原水输送过程中水质的变化。结果表明，在输水过程中，总体上典型水质指标如氨氮下降约40%，高锰酸盐指数有所下降，但浊度和菌落总数有所升高。同时，比较加氯、加炭两种预处理方法对原水的净化作用，结果发现两者对原水的预处理效果相当。
Abstract:
Water samples collected from the transmission pipeline (approximately 40 km) between JZ reservoir and SP waterworks were detected, and the changes of water quality were analyzed aimed at the problem of water quality safety in long-distance water transmission. In the process of water transmission, the typical water quality indexes such as ammonia nitrogen decreased by approximately 40%, permanganate index decreased, but turbidity and total number of bacteria increased. In addition, the pretreatment effects of different methods (chlorination/activated carbon addition) on raw water were compared, and the results showed that the pretreatment effects of raw water were similar.
