Abstract
In order to systematically study the variation of residual chlorine in the water supply network under different temperatures,the finished water from a water plant in Chongqing City had being respectively monitored under 10,15,24 ℃ and 30 ℃ in four seasons.It was found that residual chlorine decay coefficients were so different because of various temperatures:K3o℃ ＞ K24℃ ＞ K15℃ ＞ K10℃.The relationship between residual chlorine and TOC,CODMn,colony count under different temperatures and raw water qualities on every season was studied.It was practicable to change and adjust chlorine dosage in water plant based on the actual hydraulic retention time and different temperatures,which could save the costs of chlorine dosage and reduce the risks of drinking water because of the faster decay of residual chlorine by the higher temperature.关键词
