摘要
本课题对家用活性炭(以下简称 GAC)净水器的净水效能和使用方法作了一系列试验研究。研究结果表明:GAC 净水器的净水效果主要由空床流速及进水水质决定,因此在净水器的使用中,应尽可能地采用低流速,且不宜进行频繁高速反冲洗;其对自来水中各类有机物均有一定的去除效果,几乎能完全去除 C_9烷基苯及多环芳烃类有机物。GAC 净水器净水效果的综合评价,可采用 UV 值作指标,简便快速,且测试费用省。
A series of test and studies on the performance and operating oT granular active carbon (GAC) packed household water purifier had been taken with major conclusions that the efficiency of the water purifier is mainly decided by the space velocity (detention time) and the inlet water quality. The flow velocity of it should be selected as low as possible and high velocity backwashing should be carried out frequently. The organic in the water could be removed to a certain content while the Cs alkyl benzene and polynuclear aromatic hydrocarbon could be removed almost completely by the GAC purifier. Ultraviolet absorption,an easy , rapid and inexpensive test could be used as the indicator to evaluate the comprehensive efficiency of GAC filter
