一、工业锅炉烟尘排放标准修订简况 从1974年国际《工业“三废”排放标准》GBJ4—73颁布以来,对工业锅炉提出了烟尘排放浓度不得超过200mg/Nm~3的要求。十年来执行的情况说明标准偏严;全国各地区均用一个指标,不符合我国实际情况,排放标准未与锅炉厂配带除尘器后能达到的排放浓度挂起钩来,致使标准普遍不能实现,成为
I. Revision of Emission Standards for Industrial Boiler Smoke and Dust Since the promulgation of GBJ4-73, an “industrial” emission standard for waste water from industrial use in 1974, a requirement has been set for industrial boilers that the concentration of dust emission should not exceed 200mg / Nm³. The situation in the past 10 years shows that the standards are strict; all the regions use one indicator in each region, which is inconsistent with the actual situation in our country. The emission standard is not linked to the emission concentration that can be achieved after the boiler plant is equipped with a dust collector, which makes the standard generally unrealizable ,become
