一、前言日本鹿岛钢厂位于鹿岛沿海,自1971年投产以来,因工业水Cl~-浓度高,产纯水的能力低,造成配管及设备腐蚀。为了解决这一问题,在纯水装置前设置反渗透预脱盐设备(RO脱盐设备,见图1)。该设备从1973年运转至今已12年,证明能有效提高纯水水质,减少维护运转费用,效益很明显。
I. INTRODUCTION Japan’s Kashima Steel Plant is located on the coast of Kashima. Since it was put into production in 1971, due to the high Cl~ concentration in industrial water, the ability to produce pure water has been low, resulting in corrosion of piping and equipment. In order to solve this problem, a reverse osmosis pre-desalination device (RO desalination device, see Fig. 1) is installed before the pure water device. The equipment has been in operation for 12 years since 1973, which proves that it can effectively improve the quality of pure water and reduce the cost of maintenance and operation. The benefit is obvious.
