【摘要】 针对笔架山水厂示范工程提出的降低消毒剂消耗和消毒副产物生成量的目标,采取了改进药剂投加方式和对清水池结构进行优化的措施。结果表明,改变消毒剂投加方式后能节约氯耗约20%,节约能耗约15%;改进清水池结构后,使消毒剂与水的实际接触时间延长,在达到相同消毒效果的前提下降低了消毒剂的浓度,3个清水池的t10/T值分别提高了42%、21%和29%,清水池的流态也明显改善。更多还原

【Abstract】 According to the objectives on the saving of disinfectant and reduction of DBPs in the demonstration project of Bijiashan Water Plant, measures were taken for improving chemical feeding method and optimization of clear water tank configuration. The result shows that improvement of feeding method can decrease chlorine by 20% and save energy about 15%; modification of clear water configuration can increase detention time of disinfectant in water, and thus lowering the concentration of disinfectant without reducing disinfection efficiency. The t₁₀/T value is increased by 42%, 21%, and 29% respectively in the three tanks with flow pattern improved greatly.更多还原
