摘要
介绍了第二次全国污染源普查硫酸行业开展相关工作的情况,对硫酸行业产污系数手册进行解读。与第一次全国污染源普查结果相比,第二次全国污染源普查硫磺制酸二氧化硫排污系数由1.47 kg/t下降到0.41 kg/t,硫铁矿制酸废水产生量和废水中砷含量也大幅降低,行业污染物减排工作取得较大成效。进一步分析了硫酸行业二氧化硫减排的途径,企业普遍选择放弃对二氧化硫高转化率的追求,转而选择技术上相对容易实现的尾气脱硫,这种“治标不治本”的现象值得行业管理者和标准制定者思考排放标准应该如何引导行业技术进步。
The related work of sulphuric acid industry in the second national pollution source survey and the interpretation of the pollution coefficient Manual of sulphuric acid industry are introduced.Compared with the results of the first national pollution source survey,the sulphur dioxide emission coefficient of sulphur-burning sulphuric acid decreased from 1.47 kg/t to 0.41 kg/t in the second national pollution source survey,and the amount of waste water and arsenic content in the waste water are also greatly reduced,which made great achievements in pollutant emission reduction of the industry.The way of sulphur dioxide emission reduction in sulphuric acid industry is further analyzed.Enterprises generally give up the pursuit of high conversion rate of sulphur dioxide,and choose tail gas desulfurization which is relatively easy to realize in technology,this phenomenon of treating the symptoms but not the root causes is worthy of the industry managers and standard makers to think more deeply about how emission standards should guide the technological progress of the industry.
