摘要
通过将颗粒物计数方法应用于城市输配水系统,研究分析了输配水系统中颗粒物数量与浊度的相关性以及其沿线变化规律。结果表明,随着水流方向,颗粒物数量有上升趋势;管网末梢颗粒物数量和浊度偏高;颗粒粒径越小,其含量越多;在一定范围内颗粒物数量和浊度有一定相关性;对颗粒物的研究比浊度更加准确和直观。此外,从颗粒物角度对水质进行特征分析,不仅为水质评价提供更多信息,还为颗粒物计数法的应用提供基础数据。
The method of particle counting was applied to water distribution system to analyze the relevance of particles and turbidity in water distribution system, as well as the variation of particles and turbidity. The results showed that particles had a rising trend along the flow direction, and it had a high content of particles and turbidity at the end of water distribution system. The smaller the particle size was, the more the content it existed. It had a certain correlation between turbidity and particles in the certain range. The research results on particles were more exact and intuitive than turbidity. In addition, analysis of water quality in the view of particles could provide more information for water quality evaluation as well as basic data for the application of particle counting method.
