    蜜桃视频中文字幕淨化與提純的方法

    一、蜜桃视频中文字幕淨化與提純的方法

    1、 Methods of biogas purification and purification
    1、蜜桃视频中文字幕脫硫法
    1. Biogas desulfurization
    脫硫催化劑
    Desulfurization catalyst
    蜜桃视频中文字幕中的硫主要以H2S形式存在，所含有機硫較少。脫除硫化氫的方法很多，一般可分為幹法脫硫、濕法脫硫和生物脫硫。
    The sulfur in biogas mainly exists in the form of H2S and contains less organic sulfur. There are many ways to remove hydrogen sulfide, which can be generally divided into dry desulfurization, wet desulfurization and biological desulfurization.
    （1）濕法脫硫
    (1) Wet desulfurization
    濕法脫硫是利用特定的溶劑與氣體逆流接觸而脫除其中的H2S，溶劑通過再生後重新進行吸收，根據吸收機理的不同，又分為化學吸收法、物理吸收法、物理化學吸收法以及濕式氧化法。濕式氧化法脫硫效率高，單質硫可回收，流程較簡單，大多數脫硫劑可以再生，運行成本低等；同時該法流程複雜、投資大、適用於氣體處理量大，H2S含量高的場合。
    Wet desulfurization uses a specific solvent to contact with the gas countercurrent to remove H2S. The solvent is re absorbed after regeneration. According to different absorption mechanisms, it is divided into chemical absorption method, physical absorption method, physical chemical absorption method and wet oxidation method. Wet oxidation method has high desulfurization efficiency, recyclable elemental sulfur, simple process, regeneration of most desulfurizers and low operation cost; At the same time, this method has complex process, large investment and is suitable for occasions with large gas treatment capacity and high H2S content.
    （2）幹法脫硫
    (2) Dry desulfurization
    幹法脫硫通常用於低含硫氣體處理，特別是用於氣體精細脫硫。大部分幹法脫硫工藝由於需要更換脫硫劑而不能繼續操作，還有一些幹法如錳礦法、氧化鋅法、氧化鐵、活性炭等，脫硫劑不能再生或再生次數很少，脫硫飽和後要廢棄，這樣一方麵會造成環境問題，另一方麵會增加脫硫成本。
    Dry desulfurization is usually used for low sulfur gas treatment, especially for fine gas desulfurization. Most dry desulfurization processes cannot continue to operate due to the need to replace the desulfurizer. There are some dry processes such as manganese ore process, zinc oxide process, iron oxide, activated carbon, etc. the desulfurizer cannot be regenerated or the regeneration times are few. After desulfurization is saturated, it will be discarded, which will cause environmental problems on the one hand and increase the desulfurization cost on the other hand.
    （3）生物脫硫
    (3) Biological desulfurization
    生物脫硫係統以各種微生物的容納力為基礎，利用微生物的生命活動將有機汙染轉化為對人體健康和生態環境無害的化合物、生物法常用於汙水處理工程中產生的硫化物。生物脫硫技術包括生物過濾法、生物吸附法和生物滴濾法，三種係統均屬開放係統，其微生物種群隨環境改變而變化。在生物脫硫過程中，氧化態的含硫汙染物需要先經生物還原作用生成硫化物或H2S，然後再經生物氧化過程生成單質硫，才能去除。
    Based on the capacity of various microorganisms, biological desulfurization system uses the life activities of microorganisms to convert organic pollution into compounds harmless to human health and ecological environment. Biological method is often used to produce sulfide in sewage treatment projects. Biological desulfurization technology includes biological filtration, biological adsorption and biological trickle filtration. The three systems are open systems, and their microbial populations change with the change of environment. In the process of biological desulfurization, the oxidized sulfur-containing pollutants need to be removed by first generating sulfide or H2S through biological reduction, and then generating elemental sulfur through biological oxidation.
