矿区监测站试验用水处理及制备工艺

Treatment and Preparation Technique of Water for Test Operation in Monitoring and Measurement Station of Mining Area

为制备满足一级用水技术指标的分析实验室用水,采用水质软化→预处理→反渗透→混合树脂柱组合净化工艺处理自来水,并应用新型、高效的反渗透膜和精密混床树脂等先进净化材料研制成小型一体化制水机。结果表明:该工艺特别适用于原水水质硬度高,用水量少而试验用水指标要求高的监测站试验用水制备;净化后水质满足GB6682—2008《分析实验室用水规格和试验方法》中一级用水技术指标要求;并可根据用水要求灵活制备不同级别的试验用水,实现了分级取水;制水机投入运行后具备易于管理、运行费用低和不产生二次污染等优点,确保了精密仪器分析用水需求,进一步提升了监测站的监测能力。

In order to prepare and meet the first grade water technical index of water for the analysis lab application, the water softening- pre-treatment-reverse osmosis-mixed resin column combined purification technique were applied to treat the tap-water. A small integrated water machine was developed with the new and high efficient reverse osmosis membrane, fine mixing bed resin and other advanced materi- al. The results showed that the technique would be especially suitable for the monitoring and measuring station to prepare water with origi- nal water with a high hardness, less water required and high water index required for test operatiOn. The water quality after the purification would meet the requirement of the first grade water technical index of the GB6682--2008 Water Specification and Test Method of Analysis Lab. With the water application requirements, different grade of water could be flexibly prepared and thus the water could be prepared with different grades. After the water machine in operation, the management would be easy, the operation cost would be lower and no secondary pollution would be occurred. Thus the requirements of the water for the analysis of the precision instrument could be ensured and the monitoring and measuring capacity of the monitoring and measuring station could be further improved.
