一、污水处理
I. sewage treatment
污水处理行业离子交换树脂的需求数量很大，约占离子交换树脂生产量的90%，用于水里的各种阴阳离子的除去除。目前，离子交换树脂的最大使用量是用在火电站的纯净水处理上，其次是原子能、半导体材料、电子工业等。
The demand of ion exchange resin in wastewater treatment industry is very large, accounting for 90% of the production of ion exchange resin, which is used for the removal of various anions and cations in water. At present, the largest amount of ion exchange resin is used in the pure water treatment of thermal power plant, followed by atomic energy, semiconductor materials, electronic industry, etc.
二、食品产业
II. Food industry
离子交换树脂可用于制糖、鸡精、酒的特制、生物制品等工业设备上。比如：高果糖浆的制造是由苞米中萃取出淀粉后，再经水解反应，产生果糖与葡萄糖，然后经离子交换法处理，可以转化成高果糖浆。离子交换树脂在食品产业中的使用量位居污水处理之后的位置。
The ion exchange resin can be used in the industrial equipment such as sugar making, chicken essence, wine making, biological products, etc. For example, high fructose syrup is produced by extracting starch from corn, hydrolyzing it to produce fructose and glucose, and then it can be converted into high fructose syrup by ion exchange. The use of ion exchange resin in the food industry ranks in the position after sewage treatment.
