摘要
为了提高反渗透(RO)进水预处理效率,减少膜污染,本文提出一种把粉末活性炭(PAC)应用于反渗透进水预处理的新方法。该法应用粉末活性炭代替颗粒活性炭(GAC),将PAC悬浮流化在料液中;部分PAC在系统中回流;失活PAC进行适时再生。该法解决了颗粒活性炭过滤器可能会带来的生物污染问题。特别是采用PAC回流的方法充分利用了PAC的吸附能力,节省了PAC的用量。
In order to improve the efficiency of absorption and reduce the fouling of membrane, a new technique of water pretreatment by powdered activated carbon （PAC） for reverse osmosis （RO） is presented. In this new technique, PAC is substituted for GAC to make PAC suspensing in feed; partial PAC is in the state of reflux in the system and the depleted PAC is regenerated timely. The method solves the problem of biological pollution caused from GAC filter, specially the adoption of PAC reflux method fully utilizes the adsorption ability of PAC and saves the PAC quantity used.
