Secondary characteristics of biogas desulfurization
安全；脱硫塔和硫反响器的别离，防止了沼气与空气的间接接触，消弭了平安隐患。
Safety; The separation of desulfurization tower and sulfur reactor prevents indirect contact between methane and air and eliminates potential safety hazards.
本钱低；碱液耗费量的大大增加、硫单质的回收以及沼气脱硫技术设备的国产化，使得投资和运转本钱大大降低。
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.
碱液的生物循环应用；用碱性溶液吸取H2S，然后在自然界中挑选的微生物和空气的作用下将所吸取的硫化物氧化成单质硫，生化反响会重重生成碱，使碱失掉再生，重新回到洗濯塔，实际上不耗费碱。
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；被碱液吸取后的硫化氢在生化反响器中被氧化爲单质硫，单质硫经当时续的硫沉淀器及别离器后被别离出来，使废气硫化氢失掉回收，添加收益，降低脱硫本钱。在去除硫化氢的同时，回收单质硫。
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.
沼气生物脱硫
Biological Desulfurization of Biogas
零碎劣势；硫化氢去除效率高沼气生物脱硫，生物活性高，抗冲击才能强，零碎启动工夫快，工艺波动，操作复杂，可以在常温常压下运转，运转费用低（同碱洗塔相比，能浪费超越90％），不需求用铁螯合物，无后续有毒产物发生，生化复原而成的单质硫可再应用。
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.
