离子交换树脂预处理
将准备装柱使用的新树脂，先用热水（清洁的自来水即可）反复清洗，阳离子交换树脂可用70-80°C的热水，阴离子交换树脂的耐热性能较差一些，可用50-60°C热水。
The new resin for column loading should be washed repeatedly with hot water (clean tap water). Cation exchange resin can be washed repeatedly with hot water of 70-80 degrees C. The heat resistance of anion exchange resin is worse, and hot water of 50-60 degrees C can be used.
阳离子交换树脂预处理工艺：
Cation exchange resin pretreatment process:
水洗后，再经酸碱处理，阳离子交换树脂可按下述步骤进行预处理：
After washing and then treated with acid and alkali, cation exchange resin can be pretreated according to the following steps:
1、用1N盐酸缓慢流过树脂，用量约为强酸阳树脂体积的2-3倍，弱酸阳树脂的3-5倍，每小时1.5倍床层体积流过。
1. Flow slowly through the resin with 1N hydrochloric acid. The volume of the resin is about 2-3 times that of the strong acid-positive resin, 3-5 times that of the weak acid-positive resin and 1.5 times that of the bed per hour.
2、用水冲洗，出水PH为5左右，用3倍树脂体积5%的NaCl溶液流过树脂，流速与1相同。
2. Rinse with water, the effluent PH is about 5, and flow through the resin with NaCl solution of 3 times resin volume of 5%. The flow rate is the same as that of 1.
3、用1NNaOH流过树脂，用量及流速与1相同。
3, 1NNaOH flow through the resin, the dosage and the flow rate are the same as 1.
4、用水冲洗至出水PH为9左右。
4, flushing water to the effluent PH is about 9.
5、用1N盐酸或硫酸，将树脂转成H-型，用量为树脂体积的3-5倍，流速与1相同。
5. With 1N hydrochloric acid or sulphuric acid, the resin was converted into H-type, the volume of the resin was 3-5 times, and the flow rate was the same as 1.
6、酸流完后，用去离子水冲洗至出水PH值为6以上时，即可投入使用。
6, after the acid flow is finished, it can be put into operation when the pH value is above 6 when rinsed by deionized water.
阴离子交换树脂预处理工艺：
Pretreatment process of anion exchange resin:
对于阴离子交换树脂水洗后的酸、碱处理次序，可采用碱→酸→碱次序，酸、碱用量及流速，强碱树脂与强酸树脂相对应，弱碱树脂与弱酸树脂相对应。
For the acid and alkali treatment sequence of anion exchange resin after washing, the order of alkali acid alkali, the amount and flow rate of acid and alkali can be used. The strong alkali resin corresponds to the strong acid resin, and the weak alkali resin corresponds to the weak acid resin.
离子交换树脂的复活处理：
The resurrection of ion exchange resin:
在离子交换树脂使用过程中，经过一段时间运转后，往往会发生出水质量逐渐下降、交换容量逐渐降低等现象。这一般是由于树脂在运转过程中受到污染造成。在废水和生化物质提炼中，由于成份比较复杂，树脂更易受到污染，因此应采取适当的措施进行复活处理，针对不同情况，采用不同的复活处理工艺，
In the process of using ion exchange resin, after a period of operation, water quality and exchange capacity will decrease gradually. This is usually due to contamination of resin during operation. In the extraction of wastewater and biochemical substances, the resin is more vulnerable to pollution because of its complex composition. Therefore, appropriate measures should be taken to reactivate the resin. Different reactivation processes should be adopted for different situations.
