摘要
硫酸根是海水制盐、盐湖、井矿等卤水资源和采矿、冶金、制药等行业产生的高盐工业废水中主要的阴离子杂质,它的大量存在会给化工生产和环境安全造成极为不利的影响。因此,卤水和高盐工业废水在利用和排放前需要进行脱除硫酸盐处理。实验从技术原理不同的角度出发,对各种从卤水或高盐工业废水体系中脱除硫酸根的技术和方法进行了整理和分类,对其原理、操作特点、应用领域进行了总结和分析。
SO4^2-, a major anion impurities in brine from sea salt production, salt lake, mineral well, and in Hypersaline industrial Wastewater from mining industry, metallurgical industry, pharmaceutical industry, can result in adverse impact on chemical production and environmental safety. It need to be removed before brine or hypersaline industrial wastewater is used or discharged. In this paper, many methods for removing SO4^2- from brine or hypersaline industrial wastewater are summarized and elassified for their different technical principles. In addition, the technical principles, operating characteristics and application area of each method mentioned above are also summarized and analyzed.
