厭氧反應(yīng)通常會產(chǎn)生含有一定量硫化氫的沼氣。不同工業(yè)廢水沼氣中硫化氫的含量也不同。如果硫化氫含量過高，為避免管道和鍋爐腐蝕，必須在進(jìn)入鍋爐之前從沼氣中除去硫化氫。關(guān)于生物脫硫的這些特性是否足夠清楚？
Anaerobic reaction usually produces biogas containing a certain amount of hydrogen sulfide. The content of hydrogen sulfide in Biogas of different industrial wastewater is also different. If the content of hydrogen sulfide is too high, hydrogen sulfide must be removed from biogas before entering the boiler to avoid corrosion of pipes and boilers. Are these characteristics of biological desulfurization clear enough?
一種使用生物菌株從沼氣中去除高腐蝕性和高毒性硫化氫氣體的方法。該工藝具有自動化程度高，工藝簡單和運行成本低的優(yōu)點。通過厭氧發(fā)酵產(chǎn)生的沼氣進(jìn)入洗滌器，并與堿性循環(huán)霧化器反應(yīng)，以從沼氣中去除硫化氫。吸收豐富液體的硫化氫返回生物反應(yīng)器，通過生物轉(zhuǎn)化將硫化氫轉(zhuǎn)化為固體元素硫，溶液可以再生為堿性吸收劑并用于沼氣清潔，之后吸收劑被重新吸收和吸收。循環(huán)完成。硫磺固體的分離通過硫磺集塵器進(jìn)行。
A method for removing highly corrosive and highly toxic hydrogen sulfide gas from biogas by using biological strains. The process has the advantages of high automation, simple process and low operation cost. The biogas produced by anaerobic fermentation enters the scrubber and reacts with the basic circulating atomizer to remove hydrogen sulfide from the biogas. The hydrogen sulfide absorbed by rich liquid is returned to the bioreactor, and the hydrogen sulfide is converted into solid sulfur by biotransformation. The solution can be regenerated into alkaline absorbent and used for biogas cleaning, and then the absorbent is reabsorbed and absorbed. The cycle is complete. Sulfur solid is separated by sulfur dust collector.
沼氣脫硫結(jié)合了弱堿性條件下硫化氫的物理和化學(xué)吸收以及空氣中堿性溶液的生物再生。不含硫化氫的沼氣從洗滌塔頂部排出，含有硫化氫的溶液進(jìn)入生物反應(yīng)器，并在有限的氧氣供應(yīng)條件下被氧化成元素硫和堿。一些廢水和副產(chǎn)品硫不包含硫化物，可以直接排放。
Biogas desulfurization combines physical and chemical absorption of hydrogen sulfide under weak alkaline conditions and biological regeneration of alkaline solution in air. The biogas without hydrogen sulfide is discharged from the top of the scrubber. The solution containing hydrogen sulfide enters the bioreactor and is oxidized to elemental sulfur and alkali under the limited oxygen supply. Some wastewater and by-product sulfur does not contain sulfide and can be directly discharged.
