在綠色能源轉(zhuǎn)型的浪潮中，“變廢為寶”的循環(huán)模式越來越受關(guān)注。其中，厭氧發(fā)酵搭配膜法提純處理沼氣的技術(shù)，不僅能高效解決畜禽糞污、秸稈、餐廚垃圾等有機廢棄物的污染問題，還能將沼氣升級為高價值清潔能源，實現(xiàn)環(huán)保與經(jīng)濟的雙重收益。今天就給大家詳細科普，這套“厭氧發(fā)酵+膜法提純”的組合拳是如何去除沼氣雜質(zhì)、提升熱值的，以及它帶來的核心價值。

　　In the wave of green energy transformation, the circular model of "turning waste into treasure" is receiving increasing attention. Among them, the technology of anaerobic fermentation combined with membrane purification for biogas treatment can not only efficiently solve the pollution problems of organic waste such as livestock manure, straw, and kitchen waste, but also upgrade biogas into high-value clean energy, achieving dual benefits of environmental protection and economy. Today, we will give you a detailed explanation of how this combination of "anaerobic fermentation+membrane purification" can remove impurities from biogas, increase calorific value, and bring about its core value.

　　先說說整個流程的第一步——厭氧發(fā)酵，它就像一座“生物轉(zhuǎn)化工廠”。我們?nèi)粘．a(chǎn)生的畜禽糞污、農(nóng)田里的秸稈、餐館的餐廚垃圾等有機廢棄物，經(jīng)過厭氧發(fā)酵處理后，既能實現(xiàn)無害化降解，避免污染環(huán)境，還能同步產(chǎn)出沼氣和有機肥料。這種“取自自然、回歸自然”的循環(huán)理念，剛好契合綠色發(fā)展的需求。不過要注意，剛產(chǎn)出的原生沼氣并不是高品質(zhì)能源，里面含有35%-45%的二氧化碳，還有硫化氫等雜質(zhì)，不僅熱值低，應用場景也很受限，頂多只能就地用于簡單發(fā)電或燒鍋爐，很難實現(xiàn)高價值利用。

　　Let's talk about the first step of the entire process - anaerobic fermentation, which is like a "biotransformation factory". The organic waste generated in our daily lives, such as livestock manure, straw in farmland, and kitchen waste in restaurants, can be biodegraded harmlessly through anaerobic fermentation treatment, avoiding environmental pollution, and simultaneously producing biogas and organic fertilizers. This circular concept of "taking from nature and returning to nature" perfectly meets the needs of green development. However, it should be noted that the newly produced biogas is not a high-quality energy source, containing 35% -45% carbon dioxide and impurities such as hydrogen sulfide. It not only has a low calorific value, but also has limited application scenarios. At most, it can only be used locally for simple power generation or boiler burning, making it difficult to achieve high-value utilization.

　　而讓原生沼氣實現(xiàn)價值躍升的關(guān)鍵，就在于后續(xù)的膜法提純技術(shù)。膜法提純就像給沼氣做了一次“精細過濾”，通過特殊的分離膜，能精準脫除原生沼氣中的二氧化碳、硫化氫等雜質(zhì)，讓甲烷濃度提升至95%以上。升級后的沼氣，就變成了高價值的生物天然氣（BNG），熱值大幅提升，應用場景也徹底拓寬——既能并入城市燃氣管網(wǎng)供居民日常使用，也能作為車用燃料驅(qū)動汽車、船舶，還能作為工業(yè)清潔能源用于生產(chǎn)加工，真正實現(xiàn)了從“低價值沼氣”到“高價值能源”的蛻變。

　　The key to realizing the value leap of native biogas lies in the subsequent membrane purification technology. Membrane purification is like a "fine filtration" of biogas. Through a special separation membrane, impurities such as carbon dioxide and hydrogen sulfide in the original biogas can be accurately removed, increasing the methane concentration to over 95%. The upgraded biogas has become high-value bio natural gas (BNG), with significantly increased calorific value and completely expanded application scenarios - it can be integrated into urban gas pipelines for daily use by residents, used as vehicle fuel to drive cars and ships, and used as industrial clean energy for production and processing, truly achieving the transformation from "low value biogas" to "high-value energy".

　　之所以說膜法提純是優(yōu)選工藝，是因為它有著四大突出優(yōu)勢，這也是它能廣泛應用的核心原因。第一是高效節(jié)能，采用膜分離技術(shù)的沼氣提純設備，甲烷回收率能超過92%，產(chǎn)出的生物天然氣濃度穩(wěn)定在95%-99%，完全能滿足高品質(zhì)能源的需求，而且整個過程能耗相對較低；第二是操作便捷，設備采用全自動化運行模式，不用投入大量人力值守，維護成本也低，設備運行的可靠性還強，對企業(yè)來說很省心；第三是環(huán)境友好，整個提純過程不需要添加任何化學添加劑，不會產(chǎn)生二次污染，真正做到了清潔環(huán)保；第四是經(jīng)濟實用，膜法提純設備結(jié)構(gòu)緊湊，不管是投資成本還是后續(xù)的運營成本，都比其他提純工藝更有競爭力，適合不同規(guī)模的項目。

　　The reason why membrane purification is the preferred process is because it has four outstanding advantages, which are also the core reasons why it can be widely applied. The first is high efficiency and energy conservation. The biogas purification equipment using membrane separation technology can achieve a methane recovery rate of over 92%, and the concentration of produced biogas is stable at 95% -99%, fully meeting the demand for high-quality energy. Moreover, the energy consumption of the entire process is relatively low; The second is convenient operation. The equipment adopts a fully automated operation mode, which does not require a large amount of manpower to be on duty and has low maintenance costs. The reliability of equipment operation is also strong, which is very worry free for enterprises; The third is environmentally friendly, as the entire purification process does not require the addition of any chemical additives and does not produce secondary pollution, truly achieving cleanliness and environmental protection; The fourth is economic practicality. Membrane purification equipment has a compact structure, making it more competitive than other purification processes in terms of investment and subsequent operating costs, and suitable for projects of different scales.

　　這套“厭氧發(fā)酵+膜法提純”的組合，最大的價值就是構(gòu)建了完整的資源循環(huán)鏈條，實現(xiàn)了環(huán)境治理與綠色能源生產(chǎn)的統(tǒng)一。從環(huán)境層面來說，它解決了有機廢棄物的處理難題，減少了污染物排放，同時替代了傳統(tǒng)化石能源，降低了溫室氣體排放，為碳中和目標的實現(xiàn)助力；從經(jīng)濟層面來說，原本沒用的有機廢棄物變成了高價值的生物天然氣和有機肥料，企業(yè)既能通過銷售生物天然氣、有機肥料獲得收益，還能享受國家可再生能源相關(guān)補貼政策，一舉多得。

　　The greatest value of this combination of "anaerobic fermentation+membrane purification" is the construction of a complete resource cycle chain, achieving the unity of environmental governance and green energy production. From an environmental perspective, it solves the problem of organic waste disposal, reduces pollutant emissions, replaces traditional fossil fuels, reduces greenhouse gas emissions, and contributes to the achievement of carbon neutrality goals; From an economic perspective, organic waste that was originally useless has become high-value biogas and organic fertilizers. Enterprises can not only earn profits by selling biogas and organic fertilizers, but also enjoy national subsidies for renewable energy, achieving multiple benefits at once.

　　在實際應用中，這套技術(shù)的適配場景特別廣。不管是大型畜禽養(yǎng)殖場、規(guī)?；r(nóng)田秸稈處理項目，還是城市餐廚垃圾處理廠，都能用到。比如大型養(yǎng)豬場，每天會產(chǎn)生大量糞污，通過厭氧發(fā)酵處理產(chǎn)生沼氣，再經(jīng)膜法提純得到生物天然氣，既能解決糞污污染問題，又能產(chǎn)出清潔能源供場內(nèi)使用，多余的還能對外銷售，大大降低了養(yǎng)殖成本，提升了盈利空間。再比如城市餐廚垃圾處理項目，用這套技術(shù)處理垃圾的同時產(chǎn)出能源，既緩解了垃圾處理壓力，又補充了城市清潔能源供應。

　　In practical applications, this technology has a wide range of adaptation scenarios. It can be used in large-scale livestock and poultry farms, large-scale agricultural straw treatment projects, and urban kitchen waste treatment plants. For example, large-scale pig farms produce a large amount of manure every day. Anaerobic fermentation is used to produce biogas, which is then purified by membrane technology to obtain bio natural gas. This not only solves the problem of manure pollution, but also produces clean energy for on-site use. The excess can be sold externally, greatly reducing breeding costs and increasing profit margins. For example, the urban kitchen waste treatment project uses this technology to process waste while generating energy, which not only alleviates the pressure of waste treatment but also supplements the supply of clean energy in the city.

　　總結(jié)下來，厭氧發(fā)酵+膜法提純技術(shù)，通過“處理廢棄物產(chǎn)沼氣—提純沼氣升價值”的流程，真正實現(xiàn)了沼氣的變廢為寶。它不僅能高效去除沼氣雜質(zhì)、提升熱值，讓沼氣發(fā)揮更大的能源價值，還能兼顧綠色環(huán)保與經(jīng)濟獲益，是循環(huán)經(jīng)濟的典型典范。隨著這項技術(shù)的不斷普及應用，未來會有更多有機廢棄物被轉(zhuǎn)化為清潔可持續(xù)的能源，為構(gòu)建綠色能源體系、助力美麗中國建設注入源源不斷的動力。如果大家想了解更多這項技術(shù)的實際應用案例，也可以通過相關(guān)視頻鏈接進一步查看詳情。
