不同供水水质管网余氯衰减规律分析

Analysis of residual chlorine attenuation regularity for different water supply quality network

开展了不同水源、不同水质的供水管网的余氯检测工作,分析了管网余氯的衰减规律。结果表明,沿供水干线水流方向的余氯值整体呈下降趋势,但在局部管段有所升高;供水干线在冬夏两季的余氯衰减规律基本相同,混合水供水干线的余氯衰减速率最快,其次是地下水供水干线,余氯衰减速率最慢的是地表水供水干线。

The detection of residual chlorine for different water sources, water supply network with various water qualities was conducted, and the attenuation regularity of water supply network was analyzed. The results indicated that the values of residual chlorine had the tendency of decreaced along with the direction of main pipe flow, but with some increasing in partial pipeline sections. The attenuation regularity of residual chlorine of water main pipe was almost the same in winter and summer, the rate of attenuation was the lowest in surface water main pipes, the next was in groundwater main pipes, the highest was in main pipes with mixed water sources.
