The result show: The blast furnace slag is effective to remove phosphate, and "using waste treat waste" is the other characteristic. 结果表明:炉渣不但对水中的磷有良好的吸附去除性能,而且能够“以废治废”。
The Study ON the Key Influencing Factors of Diversion Tunnel Cofferdam Slag Blasting Remove Effect 导流洞围堰拆除爆破冲渣效果关键影响因素研究
Both industry waste slag and H2S can pollute the environment, but the industry waste slag can be used for remove H2S and the environment pollution will be decreased. 工业废渣和H2S都会给环境带来污染,然而工业废渣可用来去除H2S,同时减少两者对环境的污染。
In recent years, 7Al2O3 · 12 CaO refining slag is being used to purify molten steel, desulfurize and remove inclusions in the processing of LF. 铝钙渣系是近年发展起来的新型合成精炼渣,主要用于LF炉钢水脱硫、去除夹杂物,以达到净化钢液的目的。
By stirring the mixture of slag of arsenic and soda in smelting antimony at 80 ℃ for ( about) 2 h, the mixture was filtered so as to remove the antimony. 以锑冶炼产生的砷碱渣为原料,在80℃下,搅拌约2h浸出脱锑;
The experiment results show that the blast furnace slag can remove the toxic of Cr~ 6+ completely while the mass quantity of added chromium dregs was less than 10 percent. 从实验结果可以看出,当铬渣加入量低于10%时,该技术能够较彻底的将铬渣中的Cr6+进行解毒。
The results showed that the desulfurization efficiency could reach 90%. With the suitable addition amount of chlorinated lime, the sulfide and cyanide in the calcium carbide slag could remove efficiently before the desulfurization process. 结果表明,采用电石渣进行湿法烟气脱硫,脱硫效率能达到90%以上,通过投加适量的漂***,能有效去除电石渣浆液中硫化物和***。
