游离余氯(Free Chlorine Residual),氯族消毒剂,与水接触一定时间后除了与水中细菌、微生物、有机物等作用后消耗掉一部分外,还余留在水中的次氯酸(HOCl)、次氯酸根离子(OCl)或溶解的单质氯(Cl2)。用来保证持续的杀菌能力,也可用来防备供水管网受到外来污染。
更能有效吸附水中的游离氯、酚、硫、油、胶质、农药残留物和其他有机污染物,余氯、半脱氯值,以及有机溶剂的回收等。
More effective adsorption of free, phenol, sulfur, oil, resin, pesticide residues and other organic contaminants, dechlorination half the value, as well as recycling of organic solvents.
