淮河以南若干中小城市燃料煤硫品位的控制标准

DISCUSSION ON THE CONTROLLED STANDARD OF SULFUR CONTENT OF THE BURNED COAL IN THE MIDDLE AND SMALL CITIES IN THE SOUTH AREA OF THE HUAI RIVER

采用国家二级标准(O.15mg·m^(-3))作为南方中小城市的环境标准值,硫品位标准应控制在1.32%以下.对比南方各中小城市1987年使用的煤硫品位,在98个城市中,有44个城市符合标准,另有54个城市应控制高硫煤使用量或应用脱硫技术.以减少大气中SO_2浓度.

We should discuss a controlled standard of sulfur content of the burned coal in the middle and small cities And the standard should coordiate the profits of environment and the small-scale coal mines.The sulfur content should be controlled under 1. 32% , so that the quality of atmos -phere in this region does not exceed the National Second-grade Standards (0. 15mg · m-3). By comparing the sulfur content of the coal used in middle and small cities in 1978 in south China with the standard ,we can know that only 44 cities satisfied the standard among 98 cities. We suggest that the other 54 cities should slow down the consumption of the high-sulfur content coal or take desulfration to reduce the concentration of SO2 in atmosphere.
