长期以来,各盐化工企业以食盐为主要原料,用电解方法在制取氯、氢和烧碱过程中产生废物,以泥浆的形式存在,俗称盐泥。按目前全国烧碱350万t/a计算,排浆量在60万t/a左右。这种工业废物通常直接排入江河,造成严重的环境污染。为了消除盐泥对环境的污染,依据《全国尾矿库专项整治行动》的指示和《全国尾矿综合利用专项规划》等文件精神,实现建立绿色矿山,达到清洁生产的目标。从2008年起,宝鸡航天动力泵业有限公司先后与湖北、河南、安徽等4家盐化工企业通力合作,开
For a long time, the salt chemical companies to salt as the main raw material, electrolysis in the production of chlorine, hydrogen and caustic soda generated in the process of waste, in the form of mud, commonly known as salt. According to the current national caustic soda 3500000 t / a calculation, drainage volume of 600000 t / a or so. This industrial waste is usually discharged directly into the river, causing serious environmental pollution. In order to eliminate the pollution of salt mud to the environment, the goal of clean production has been achieved by establishing a green mine based on the document “National Tailings Remediation Action” and the “National Tailings Comprehensive Utilization Plan”. Since 2008, Baoji Aerospace Power Pump Co., Ltd. has cooperated with four salt chemical enterprises in Hubei, Henan and Anhui successively to open
