The invention provides a granular resin film laying method and a resin recovery device. The method is suitable for finely treating a precoat filter system with condensed water in a thermal power generation plant. The method is characterized in that: (1) granular anion and cation exchange resin is laid in a filter, which can remove impurities such as F<->, SiO2, Cl<->, Na<+>, CO2 and Fe (including suspending Fe and solvent Fe) out of the condensed water especially when the temperature of the condensed water is higher, the granular resin has a favorable removal effect on SiO2 as compared with the traditional process of laying powdery resin and fiber powder; and (2) resin is recovered by a special device when the resin loses efficacy, and then the recovered resin is subjected to external regeneration intensively, thus the recycling use of the resin is realized. Through the method, the impurity removing capability of the filter is improved, effluent water has good quality, adaptability is strong ...
