煤脱硫技术及脱硫废液再利用问题的研究

Research on Coal Desulfurization Technology and Reuse of Desulfurization Waste Liquid

我国煤炭资源含量丰富,在我国主要的能源消费结构中,煤炭占据了主导地位。但由于煤炭的燃烧会产出大量的有毒有害物质,特别是含硫废气导致的酸雨和光化学污染与当今环保绿色发展的理念不符。对于新疆的煤焦化企业来说,运用最广泛的脱硫方式为氨法脱硫,但产生了大量无法直接处理的脱硫废液。目前,国内外学者对于煤脱硫的研究发表了一系列成果。本文就脱硫废液该如何处理的问题总结,并且对脱硫废液再利用的问题进行剖析,为今后脱硫废液的处理问题提供参考。

China is rich in coal resource content, and coal dominates the main energy consumption structure in China. However, the combustion of coal produces a large amount of toxic and harmful substances, especially the acid rain and photochemical pollution caused by sulfur-containing exhaust gases are not in line with today’s concept of environmental protection and green development. For coal coking enterprises in Xinjiang, the most widely used desulfurization method is ammonia desulfurization, but it produces a large amount of desulfurization waste liquid that cannot be directly treated. At present, domestic and foreign scholars have published a series of results on the research of coal desulfurization. This paper summarizes the problem of how to deal with desulfurization waste liquid and analyzes the problem of reusing desulfurization waste liquid to provide a reference for the future treatment of desulfurization waste liquid.
