本研究通过调查、分析，对长江原水水质现状作了综合全面的评价，并掌握了其变化趋势。研究表明：长江原水水质的综合评价为Ⅱ级水源标准。陈行水库的蓄存作用对去除浊度、有机物、铁、锰等的效果非常显著，对由于水质变化而对水厂产生的冲击起了很好的缓解作用。由于取自陈行水库的水量增加，原水的浊度、有机物含量等有所增加。但由于陈行水库的缓冲作用，原水水质的变化不会很大。藻类不大会对水厂运行造成危害。另外对月浦水厂的处理工艺的调查表明现有的处理工艺基本适应长江水质。但在冬季低温低浊时，处理效果还不十分理想。如何处理低温低浊水源水仍是一个值得研究的课题。
Through investigation and analysis, this study made a comprehensive and comprehensive evaluation of the current status of the Yangtze River raw water quality and mastered its changing trends. Research shows that: The comprehensive evaluation of the raw water quality of the Yangtze River is a Class II water source standard. The storage effect of Chenhang Reservoir is very effective in removing turbidity, organic matter, iron, manganese, etc., and has a good alleviation effect on the impact of water quality on the water plant. As the amount of water taken from Chenxing Reservoir increased, the turbidity and organic content of the raw water increased. However, due to the buffering effect of Chenxing Reservoir, the quality of raw water will not change much. Algae does not cause harm to the operation of water plants. In addition, the investigation of the treatment process at the Yuepu Water Plant shows that the existing treatment process basically adapts to the water quality of the Yangtze River. However, in the winter when the low temperature and low turbidity, the treatment effect is not very satisfactory. How to deal with low temperature and low turbidity source water is still a subject worthy of study.
