摘　　要：考察了改性阴离子树脂对工业废水中高浓度氯离子的去除特性。实验表明,改性硫酸根型阴离子树脂具有稳定的除氯效果,在1.33~4.00 m L·min^(-1)区间的流速不影响除氯效果。预处理浓度为"先1%NaOH、再4%H_2SO_4"与"先3%NaOH、再2%H_2SO_4"在投加量2.5~5.0m L·g^(-1)时有较好的氯离子即时吸附量和较高的COD_(Cr)去除率,COD_(Cr)的去除率达80%。The removal characteristics of high concentration of chloride from an industrial wastewater by modified anion ion exchange resins were investigated. The results show that the modified sulfate-ion exchange resins have a stable chloride removal performance, and the flow rate at the range of 1.33,-4.00 mL·min-1 did not affect the chloride removal. The pretreatment concentration of ＂1% NaOH and 4 % H2SO4 ＂and ＂ 3 % NaOH and 2 % H2SO4 ＂ were found to have good adsorption capacity for chloride and CODer removal at the dosage of 2.5-5.0 mL·g-1, CODcr removal rate of 80 %.
