1 .某金属冶炼厂的管道烟泥中含有某些金属,随机取样对烟泥进行分析.由表1中的数据可知,在烟泥中含有相当量的铜、锌以及能造成污染的硫.因此,从效益和环保角度出发,应考虑把铜、锌回收利用,并对硫进行适当的处理.表1 烟泥样品中部分元素质量分数表CuZnS110 3% 5 0 % 1 2 %2
1. The metallurgical sludge in a certain metal smelter contains certain metals, and random sampling is used to analyze the sludge. From the data in Table 1, it can be seen that there are considerable amounts of copper, zinc, and sulfur that can cause pollution in the smoke sludge. Therefore, from the perspective of efficiency and environmental protection, consideration should be given to the recycling of copper and zinc and appropriate treatment of sulfur.
