沼氣脫硫次要特性
Secondary characteristics of biogas desulfurization
安全；脫硫塔和硫反響器的別離，防止了沼氣與空氣的間接接觸，消弭了平安隱患。
Safety; The separation of desulfurization tower and sulfur reactor prevents indirect contact between methane and air and eliminates potential safety hazards.
本錢低；堿液耗費量的大大增加、硫單質(zhì)的回收以及沼氣脫硫技術(shù)設(shè)備的國產(chǎn)化，使得投資和運轉(zhuǎn)本錢大大降低。
The cost is low; the cost of investment and operation is greatly reduced due to the increase of alkali consumption, the recovery of sulfur and the localization of biogas desulfurization technology and equipment.
堿液的生物循環(huán)應(yīng)用；用堿性溶液吸收H2S，然后在自然界中挑選的微生物和空氣的作用下將所吸收的硫化物氧化成單質(zhì)硫，生化反響會重重生成堿，使堿失掉再生，重新回到洗濯塔，實際上不耗費堿。
Biological recycling application of alkaline solution; absorbing H2S with alkaline solution, then oxidizing the absorbed sulfide into elemental sulfur under the action of selected microorganisms and air in nature, the biochemical reaction will regenerate alkali, make alkali lose and regenerate, and return to the wash tower, which in fact does not consume alkali.
硫回收；被堿液吸收后的硫化氫在生化反響器中被氧化爲單質(zhì)硫，單質(zhì)硫經(jīng)當時續(xù)的硫沉淀器及別離器后被別離出來，使廢氣硫化氫失掉回收，添加收益，降低脫硫本錢。在去除硫化氫的同時，回收單質(zhì)硫。
Sulphur recovery; hydrogen sulfide absorbed by alkali liquor is oxidized to elemental sulfur in biochemical reactor, elemental sulfur is separated after successive sulfur precipitator and separator, so that waste gas hydrogen sulfide is lost and recovered, added revenue and reduced desulfurization cost. While removing hydrogen sulfide, the elemental sulfur is recovered.

Biological Desulfurization of Biogas
零碎劣勢；硫化氫去除效率高沼氣生物脫硫，生物活性高，抗沖擊才能強，零碎啟動工夫快，工藝波動，操作復雜，可以在常溫常壓下運轉(zhuǎn)，運轉(zhuǎn)費用低（同堿洗塔相比，能浪費超越90％），不需求用鐵螯合物，無后續(xù)有毒產(chǎn)物發(fā)生，生化復原而成的單質(zhì)硫可再應(yīng)用。
Fragmentation disadvantage; high removal efficiency of hydrogen sulfide, high biological activity, strong impact resistance, quick start-up time, process fluctuation, complex operation, can operate at room temperature and pressure, low operating costs (compared with alkali scrubber, can waste more than 90%), no need for iron chelates, no subsequent toxic products, biochemical recovery of elemental sulfur can be reacted. Use.
In summary, all the above-mentioned Shandong Heneng Environmental Protection Energy Equipment Co., Ltd. provides, want to know more about biogas desulfurization knowledge, welcome to pay attention to our website: http://www.twld888.cn Thank you for your support!
