生物脫硫技術(shù)就是利用微生物或酶催化沼氣中所含的硫化合物(H2S、有機硫),將其所含硫有機物轉(zhuǎn)化成可回收利用的單質(zhì)硫,提高沼氣的濃度,減少沼氣燃燒給大氣帶來的污染。隨著國家環(huán)保政策和人們環(huán)保意識的增強,沼氣脫硫成為了現(xiàn)代沼氣應(yīng)用的趨勢,而生物脫硫技術(shù)與傳統(tǒng)脫硫方式相比,生物脫硫技術(shù)更具有其他脫硫工藝無法比擬的優(yōu)勢:
Biological desulfurization technology is to use microorganisms or enzymes to catalyze sulfur compounds (H2S, organic sulfur) contained in biogas to convert sulfur-containing organic matter into recoverable elemental sulfur, improve the concentration of biogas, and reduce the pollution of the atmosphere caused by biogas combustion. With the enhancement of national environmental protection policy and people's awareness of environmental protection, biogas desulfurization has become the trend of modern biogas application. Compared with traditional desulfurization methods, biodesulfurization technology has more advantages than other desulfurization processes.
1.脫硫效率高。生物脫硫技術(shù)運行中硫化氫(H2S)去除率可高達(dá)到99.5%以上,并可去除其它有機硫化物,如(COS)氧硫化碳。
1. High desulfurization efficiency. The removal rate of hydrogen sulfide (H2S) can reach over 99.5% in the operation of biological desulfurization technology, and other organic sulfides, such as carbon oxysulfide (COS), can be removed.
2.運行成本低。生物脫硫運行不需要添加昂貴的化學(xué)試劑,運行成本是傳統(tǒng)脫硫工藝的十分之一,乃至幾十分之一。
2. Low operating cost. Biological desulfurization operation does not need to add expensive chemical reagents, and the operation cost is one tenth or even one tenth of the traditional desulfurization process.
3.運行非常穩(wěn)定。生物脫硫生產(chǎn)的單質(zhì)硫水溶性非常好,不會堵塞管道,而傳統(tǒng)的干法脫硫工藝大的弊端是經(jīng)常性堵塞。
3. The operation is very stable. The water solubility of sulfur in biological desulfurization production is very good, and the pipeline will not be blocked. The biggest disadvantage of traditional dry desulfurization process is frequent blockage.
4.無二次污染。傳統(tǒng)的濕法脫硫會產(chǎn)生大量的洗滌液廢水,傳統(tǒng)干法脫硫工藝會產(chǎn)生大量的固體廢棄物,都容易產(chǎn)生二次污染,而生物脫硫產(chǎn)生的單質(zhì)硫通過沉淀的方式直接可回收利用,無二次污染。
4. No secondary pollution. Traditional wet desulfurization will produce a large amount of washing liquid wastewater. Traditional dry desulfurization process will produce a large number of solid wastes, which are prone to secondary pollution. The elemental sulfur produced by biological desulfurization can be directly recycled by precipitation without secondary pollution.
5.勞動強度低。傳統(tǒng)干法脫硫工藝需要經(jīng)常更換脫硫劑,勞動強度大,而生物脫硫工藝運行穩(wěn)定,基本不需要設(shè)備維護(hù)。
5. Low labor intensity. The traditional dry desulfurization process needs to replace desulfurizer frequently, which has high labor intensity, while the biological desulfurization process runs steadily and basically does not need equipment maintenance.
生物脫硫技術(shù)運行效率高,廣泛應(yīng)用于各行各業(yè),越來越成為眾多用戶的脫硫方式。
Biological desulfurization technology has high operational efficiency and is widely used in all walks of life. It has become the preferred desulfurization method for many users.
