KDF55处理饮用水的试验研究

Experimental Study on Drinking Water Treatment by KDF55

采用新型合金滤料凯得菲(KDF55)分别在连续通水和静态试验条件下处理饮用水,考察了不同试验条件下的处理效果。结果表明,在连续通水和静态试验条件下,KDF55对浊度的去除率分别可达到41.1%、76.1%,对CODMn的去除率分别为13.3%、13.7%,对总硬度的去除率分别为7%、20%;受水力条件和装置结构形式的影响,KDF55在静态条件下对饮用水的处理效果优于连续通水时的。研究结果可为小型家用净水器的研发及使用提供重要参考。

KDF55 was used to treat drinking water under two test conditions of running and still water, and the treatment effect under the different test conditions was investigated. The results show that under the test conditions of running and still water, the removal rates of turbidity are 41. 1% and 76.1%, those of CODM,, are 13.3% and 13.7%, and those of total hardness are 7% and 20% respectively. The removal effect of drinking water by KDF55 under the condition of still water is better than that under the condition of running water, which is influenced by hydraulic conditions and device structure. The study results can provide important reference for the development and use of household water purifiers.
