摘要
介绍了我公司《日处理1000m3制硝废水资源综合利用项目》情况。该项目通过新型的盐析工艺,做到对生产元明粉在制硝过程中,把外排废水中的硝、盐进行分离,同时回收废水中的Na2SO4、NaCl,达到制硝废水的零排放,保护了环境,又使废弃物资源得到综合利用。因此,该技术研究与应用,在国内外代表着该领域的技术创新和发展趋势。
This paper introduces our company＇s project ＂Comprehensive Utilization for 1000m^3 per day Treatment of Waste Water from Sodium Sulfate Making＂.Salt and sodium sulfate in the purged waste are seperated in the process of making sodium sulfate by means of a new salting out technology,and Na2SO4 and NaCl are recovered to reach the aim of zero emmission of the waste,enviromental protection and comprehensive utilization of the waste resources.Thus,the research and application of this technology represents the tendency of technological creation and development.
