    生物脫硫技術對大型91无码麻豆视频工程有多重要?

    目前91无码麻豆视频脫硫的方法有兩大類，即物理化學法和生物法。物理化學法包括幹法脫硫和濕法脫硫，已被廣泛地應用且積累了豐富的經驗，但該方法存在運行費用高、投資大、產生二次汙染等缺點；而生物法以不需催化劑和氧化劑、不需處理化學汙泥、少汙染、低能耗、高 效 率、可回收單質硫等優點，引起了人們的廣泛關注。為此，筆者以某有限公司熱電聯產91无码麻豆视频工程為例，介紹了該91无码麻豆视频工程調試與運行時生物脫硫技術的具體運用。

    At present, there are two kinds of biogas desulfurization methods, namely physical-chemical method and biological method. Physicochemical methods, including dry desulfurization and wet desulfurization, have been widely used and accumulated rich experience, but this method has the disadvantages of high operation cost, large investment and secondary pollution; Biological process has attracted extensive attention because of its advantages such as no catalyst and oxidant, no treatment of chemical sludge, less pollution, low energy consumption, high efficiency and recyclable elemental sulfur. Therefore, taking the cogeneration biogas project of a limited company as an example, the author introduces the specific application of biological desulfurization technology during the commissioning and operation of the biogas project.
    生物脫硫的裝置主要由生物脫硫塔和曝氣水箱構成，從厭氧罐內導出的91无码麻豆视频由脫硫塔底部進入，脫硫循環水由泵打入脫硫塔頂，兩者在塔內逆向接觸反應，且塔內充有填料以供脫硫菌附著生長，同時也利於氣水均勻分布以充分接觸。生物脫硫塔及曝氣水箱都采用耐酸玻璃鋼製作，循環泵也使用耐酸性泵。脫硫塔的負荷為8m3(91无码麻豆视频)/（m3·h）左右。
    生物脫硫
    The biological desulfurization device is mainly composed of biological desulfurization tower and aeration water tank. The biogas derived from the anaerobic tank enters from the bottom of the desulfurization tower, and the desulfurization circulating water is pumped into the top of the desulfurization tower. The two react in reverse contact in the tower, and the tower is filled with filler for the attachment and growth of desulfurization bacteria. At the same time, it is also conducive to the uniform distribution of gas and water for full contact. The biological desulfurization tower and aeration water tank are made of acid resistant FRP, and the circulating pump also uses acid resistant pump. The load of desulfurization tower is about 8m3 (biogas) / (M3 · h).
    本工程采用生物脫硫的方法對91无码麻豆视频進行脫硫處理，主要利用無色硫細 菌在適宜的溫度、濕度和微氧條件下的代謝作用將H2S氧化成單質硫或亞硫酸。生物脫硫分為3個階段:
    In this project, biological desulfurization method is adopted for desulfurization of biogas, which mainly uses the metabolism of colorless sulfur bacteria under appropriate temperature, humidity and micro oxygen conditions to oxidize H2S into elemental sulfur or sulfite. Biological desulfurization is divided into three stages:
    1.H2S氣體的溶解過程，即由氣相轉化為液相；
    1. Dissolution process of H2S gas, i.e. conversion from gas phase to liquid phase;
    2.溶解後的H2S被微生物吸收，轉移至微生物的體內；
    2. The dissolved H2S is absorbed by microorganisms and transferred to microorganisms;
    3.進入微生物細胞內的H2S作為營養物被微生物分 解、轉化和利用，從而達到去除H2S的目的。
    3. H2S entering microbial cells is decomposed, transformed and utilized by microorganisms as nutrients, so as to achieve the purpose of removing H2S.
    雖然生物脫硫具有能耗少、去除率高等特點，但必 須給硫細 菌營造一個適宜的環境，才能確保其具有較高的生物活 性，以達到好的脫硫效果
    Although biological desulfurization has the characteristics of low energy consumption and high removal rate, it is necessary to create a suitable environment for sulfur bacteria in order to ensure its high biological activity and achieve good desulfurization effect
