摘要
通过系统分析南风化工集团元明粉的生产工艺,定量地描述了其对大气、水、声环境的影响。元明粉生产工艺产生的主要大气污染物是干燥系统尾气中的硫酸钠粉尘,通过旋风及湿法除尘,即可回收利用硫酸钠,又使废气达标排放。工艺过程产生的各种废水,全部回收用于溶化原料,废水零排放。各设备噪声采取相应减震、减噪措施,厂界噪声达标。固体废物用于原料生产及铺路。
By means of systemetical analysis on the production process of anhydrous sodium sulfate in Nafine Chemical Industry Group Co. , Ltd. , the impacts of the process on the environment of air, water, and sound were described quantitatively. The major air pollutant generated in the anhydrous sodium sulfate production is sodium sulfate dust in the tail gas from drying system. Through cyclone and wet - method to collect the dust, not only the sodium sulfate can be recovered,but also the discharge of waste gas can meet the discharge standard. Moreovers the various kinds of wastewater in the process were all used to dissolve chemical raw materials and realized wastewater zero drainage thereby. All the equipment adopted corresponding shock - absorbing and noise controlling measures and the noise within battery limit was in accord with the relative standard. There was no solid wastes stacking,which were all used for raw materials production and paving the way.
