近年来,随着我国社会的发展,国内经济水平的不断提高,人们生活水平逐步提升,沼气的使用现象已经越来越普遍。沼气虽好,但是含有有毒有害气体硫化氢,由于硫化氢有毒、腐蚀性很强,对人们身体有着很大的危害,因此,如何有效且经济地处理这些沼气中的有毒有害气体--硫化氢,是衡量一个沼气利用项目成功的重要因素。无锡市诺帕尔生物科技有限公司就是一家主营从事沼气脱硫工程的高新技术企业,现如今,随着科技的发展、技术的更替,沼气脱硫技术已发展到以生物脱硫为代表的沼气脱硫技术。其中生物脱硫又大体分为一体式生物脱硫和分离式生物脱硫这两种脱硫方式。
In recent years, with the development of China's society, the continuous improvement of domestic economic level, people's living standards have gradually improved, the use of biogas has become more and more common. Although biogas is good, it contains poisonous and harmful gas hydrogen sulfide. Because hydrogen sulfide is toxic and corrosive, it has great harm to people's health. Therefore, how to effectively and economically deal with the poisonous and harmful gas hydrogen sulfide in biogas is an important factor to measure the success of a biogas utilization project. Wuxi nuopal Biotechnology Co., Ltd. is a high-tech enterprise mainly engaged in biogas desulfurization project. Nowadays, with the development of science and technology and the replacement of technology, biogas desulfurization technology has developed to the biogas desulfurization technology represented by biological desulfurization. Among them, biological desulfurization is generally divided into integrated biological desulfurization and separated biological desulfurization.
在一体式生物脱硫和分离式生物脱硫这两种脱硫方式中,一体式生物脱硫是指:将一定量的空气导入含有硫化氢的沼气中,这种混合气体会通过生物滤池、生物滴滤池以去除硫化氢,脱硫副产物一般为硫酸或者硫酸盐。由于一体式生物脱硫技术运行的成本非常低,所以现如今,被广泛应用于沼气脱硫发电项目中,发展前景广阔。
In the integrated biological desulfurization and separate biological desulfurization, the integrated biological desulfurization refers to that a certain amount of air is introduced into the biogas containing hydrogen sulfide, and the mixed gas will be removed by biological filter and biotrickling filter, and the by-product of desulfurization is generally sulfuric acid or sulfate. Because the operation cost of integrated biological desulfurization technology is very low, so now, it is widely used in biogas desulfurization power generation project, and has broad development prospects.

其中的分离式生物脱硫工艺指的是含硫化氢的沼气气体在进入生物洗涤塔内后,在塔内与碱起到反应,先从沼气中脱除硫化氢,然后生物洗涤液进入生物反应器。将反应器中的硫化物转化为单质硫,同时碱液得到再生,可以重复使用。随着嗜盐脱硫菌的发现,分离式脱硫工艺得到了长足的发展。并且随着科技的进步,更加解决了一体式生物脱硫容易出现的硫填料易堵塞的问题。在沼气提纯CNG的工艺中、以及高浓度硫化氢的沼气处理工艺中,分离式脱硫工艺占有优势。以上就是生物脱硫的介绍。
In the biogas scrubber, the gas containing hydrogen sulfide enters into the biological scrubber first, and then enters the biological scrubbing reactor. The sulfide in the reactor is converted into elemental sulfur, and the alkali liquor is regenerated, which can be reused. With the discovery of halophilic desulfurizing bacteria, the separation desulfurization process has been greatly developed. And with the progress of science and technology, it has solved the problem that sulfur filler is easy to block in integrated biological desulfurization. In the process of purification of CNG from biogas and the treatment process of high concentration hydrogen sulfide, the separation desulfurization process has the advantage. The above is the introduction of biological desulfurization.
