四、树脂使用须知：

1. 1.清洗离子交换塔及管道，保证容器和管道无杂物；

2. 2.除氟树脂的装填至离子交换塔，至规定高度后，摊平树脂，封堵人孔，试压检漏；

3. 3.调整阀门至逆流清洗状态，用去离子水清洗树脂至出水清澈透亮；

4. 4.切换阀门至正吸附状态，调整流量值5-15BV/h，即可进入使用；

5. 5.检测出水水质，当在线检测F-超过规定限制后及时切换下一塔吸附，本塔进入解析状态；6.解吸塔先用去离子水冲洗3BV，然后用去离子水配制的3-5%的氢氧化钠溶液进行解吸5BV，然后用去离子水清洗至pH9-10，进入待吸附状态。

The Ultrahigh Adsorption Defluorinated Resin

1.Product Introduction

The ultrahigh adsorption defluorinated resin is a polymerresin with speclal functional groups, which has specific selectivity forfuorine ion. The fealures include high adsorplion capacly, beller seleclivity, high processing precision. Compared with similarproducts at home and abroad, the resin consumption is less and the service life is longer under the same condition. This resin is

simole o operate and does not require aluminum salt redeneration, The fuorine content of erfuent can be maintained stably below1 ppm.The ultrahigh adsorption defluorinated resin has high acid and alkali resistant, and has specific selective adsorption for F-inthe acidic system with pH of 4-6.It can tolerate 2M sulfuric acid. It has beter selectivity for fluorine in the system containing chloridejons, sulfate and nitrate, so it has excellentdefluorination performance.

4.Instructions for Operation

1. 1.Clean the ion exchange tower and pipe to ensure that there is no other things in the container:

2. 2. After loading the defluorinated resin into the specified height of the ion exchange tower, ensure the resin is flattened, the hole isblocked,and the pressure is tested for leakage;

3. 3, Adiust the valve to countercurrent cleaning state. clean the resin with deionized water until the water is clear;

4. 4, The operation can be started after switchina the valve to the positive adsorption state and adiusting the flow value to 5-15BV/h

5. 5. The effluent ouality needs to be tested. When the on-ine detection of F- exceeds the specified limit, the column enters thedesorption state and switch the next column adsorption in time:

6. 6. Desortion tower needs to wash to 3BY with deionized water first, and then desorption to 5BY with 3-5% Na0H solution prepareowith deionized water, and finally clean with deionized water to pH 9-10, then enter the state to be adsorbed.
