The adsorption behavior of XDA-11 resin on methylene blue textile dyeing wastewater was studied.The effects of adsorption time,pH value,temperature and flow rate on the adsorption performance of the resin were investigated.The results showed that the decolorization rate of 80.0 mL,50 mg/L wastewater treated with 0.1200 g resin was about 99.66%at 48℃,pH 11 and 4.5 hours of static adsorption;under the condition of dynamic adsorption,when the pH value is adjusted to 11 at room temperature and the adsorption flow rate is 2 BV/h,the wastewater treatment capacity reached 126 BV,and the decolorization rate was about 99.98%;the resin was regenerated with hydrochloric acid-basic ethanol for several times,and the regeneration rate was over 73%.
