摘要: 用厌氧消化法对氧化铝冶炼过程中产生的草酸盐废弃物进行处置. 实验结果表明,草酸盐可以转化成无害的甲烷和HCO3-,反应需在温和的条件下进行并辅以外来碳源. 底物浓度过高或pH值过高均会抑制草酸盐降解. 当底物浓度超过0.25 mol/L或pH>10时,草酸盐的降解完全停止. 外加碳源乙酸可以极大促进草酸盐的降解.

Abstract: Mechanism analysis and emission measurement indicate that the NOx-suppressed smokeless coal combustion technique can reduce NO and smoke emission simultaneously and improve combustion efficiency. Its application to coal-fired kilns is presented by comparing the emission from the modified and unmodified kilns.

Key words: kiln, nitrogen oxide, carbon mono-oxide, soot
