近两年,经过各地区、各部门的共同努力,我国资源综合利用工作已取得比较明显的进展。主要表现在:1988年,全国综合利用工业废渣1.47亿吨,比1987年多利用1000万吨,综合利用率由25％提高到26％。工业废气和废液的回收发展也很快,1988年,焦炉煤气和高炉煤气的回收率分别达到97.3％和90.4％。有色冶炼烟气回收二氧化化硫制酸165万吨,轻工造纸废液碱回收33.2万吨。1988年,全国工业“三废”资源综合利用的产值50亿元,比1986年增加20亿元,利润15.7亿元,增加7.2亿元。与
In the past two years, thanks to the joint efforts of various regions and departments, the comprehensive utilization of resources in our country has made remarkable progress. Mainly in: In 1988, the national comprehensive utilization of industrial waste 147 million tons, more than 10 million tons in 1987, the comprehensive utilization rate increased from 25% to 26%. The recovery of industrial waste gas and waste liquid also developed rapidly. In 1988, the recovery rates of coke oven gas and blast furnace gas reached 97.3% and 90.4% respectively. Non-ferrous smelting flue gas sulfur dioxide recovery of sulfuric acid 1.65 million tons, light papermaking waste alkali recovery of 332,000 tons. In 1988, the output value of comprehensive utilization of industrial “three wastes” resources was 5 billion yuan, an increase of 2 billion yuan over 1986 and a profit of 1.57 billion yuan, an increase of 720 million yuan. versus
