　　How much does it cost to invest in biogas purification in modern pig farms? Cost breakdown here

　　現(xiàn)在越來(lái)越多現(xiàn)代化養(yǎng)豬場(chǎng)開(kāi)始搞沼氣資源化利用，其中沼氣提純（也就是生物天然氣提純）是提升沼氣價(jià)值的關(guān)鍵一步。但很多豬場(chǎng)經(jīng)營(yíng)者最關(guān)心的問(wèn)題是：搞一套沼氣提純系統(tǒng)到底要花多少錢？其實(shí)這個(gè)問(wèn)題沒(méi)有固定答案，投資成本受養(yǎng)殖規(guī)模、沼氣產(chǎn)量、提純工藝、設(shè)備選型等多種因素影響。今天就給大家詳細(xì)科普，按不同養(yǎng)殖規(guī)模拆解沼氣提純的投資范圍，再說(shuō)說(shuō)影響成本的關(guān)鍵因素，幫大家心里有個(gè)底。

　　More and more modern pig farms are now engaging in the resource utilization of biogas, among which biogas purification (i.e. bio natural gas purification) is a key step in enhancing the value of biogas. But the biggest concern for many pig farm operators is: how much does it cost to develop a biogas purification system? In fact, there is no fixed answer to this question, and investment costs are influenced by various factors such as breeding scale, biogas production, purification technology, and equipment selection. Today, we will give you a detailed explanation of the investment scope for biogas purification based on different breeding scales, as well as the key factors that affect costs, to help you have a clear understanding.

　　先看中小型現(xiàn)代化養(yǎng)豬場(chǎng)，這類豬場(chǎng)存欄規(guī)模大概在5000到10000頭。對(duì)應(yīng)到沼氣提純項(xiàng)目，投資成本大概在200萬(wàn)到500萬(wàn)元之間。這個(gè)區(qū)間是怎么來(lái)的呢？主要看沼氣產(chǎn)量——這類豬場(chǎng)年產(chǎn)沼氣通常在10萬(wàn)到30萬(wàn)立方米，經(jīng)過(guò)提純后能得到5萬(wàn)到15萬(wàn)立方米的生物天然氣。這里有個(gè)實(shí)用提醒：如果豬場(chǎng)搞沼氣提純只是為了自己發(fā)電用，或者作為場(chǎng)內(nèi)能源自用，不用達(dá)到商用天然氣標(biāo)準(zhǔn)，就可以簡(jiǎn)化提純工藝，相應(yīng)的投資成本也能降不少，不用非要按最高標(biāo)準(zhǔn)投入。

　　Firstly, focus on small-scale modern pig farms with a stock size of approximately 5000 to 10000 pigs. Corresponding to the biogas purification project, the investment cost is approximately between 2 million and 5 million yuan. How did this interval come about? Mainly based on biogas production - this type of pig farm usually produces 100000 to 300000 cubic meters of biogas annually, which can be purified to obtain 50000 to 150000 cubic meters of bio natural gas. Here is a practical reminder: if a pig farm engages in biogas purification only for its own power generation or for internal energy use, without meeting commercial natural gas standards, the purification process can be simplified and the corresponding investment costs can be reduced significantly, without having to invest according to the highest standards.

　　再來(lái)說(shuō)大型現(xiàn)代化養(yǎng)豬場(chǎng)，存欄規(guī)模在1萬(wàn)到5萬(wàn)頭以上的，沼氣提純項(xiàng)目投資就會(huì)高一些，大概在500萬(wàn)到1500萬(wàn)元。這類豬場(chǎng)養(yǎng)殖規(guī)模大，糞污產(chǎn)量多，年產(chǎn)沼氣能達(dá)到30萬(wàn)到100萬(wàn)立方米，提純后可產(chǎn)出15萬(wàn)到50萬(wàn)立方米的生物天然氣。之所以投資區(qū)間跨度大，主要是因?yàn)榇笮拓i場(chǎng)的沼氣產(chǎn)量波動(dòng)范圍廣，而且很多大型項(xiàng)目會(huì)追求更高的提純效率和生物天然氣純度，比如要接入城市燃?xì)夤芫W(wǎng)或者對(duì)外銷售，就需要更先進(jìn)的工藝和更大型的設(shè)備，成本自然會(huì)上升。

　　Speaking of large-scale modern pig farms with a stock size of over 10000 to 50000 heads, the investment in biogas purification projects will be higher, about 5 to 15 million yuan. This type of pig farm has a large scale of breeding and a high output of manure. The annual production of biogas can reach 300000 to 1 million cubic meters, and after purification, it can produce 150000 to 500000 cubic meters of bio natural gas. The reason for the wide investment range is mainly due to the wide fluctuation range of biogas production in large pig farms, and many large-scale projects pursue higher purification efficiency and biogas purity. For example, to connect to urban gas pipelines or sell to the outside world, more advanced processes and larger equipment are required, and the cost will naturally increase.

　　了解了大致投資范圍，再說(shuō)說(shuō)哪些因素會(huì)直接影響投資成本。第一個(gè)關(guān)鍵因素是養(yǎng)殖規(guī)模和沼氣產(chǎn)量，這是決定成本的基礎(chǔ)——規(guī)模越大、產(chǎn)氣越多，需要的提純?cè)O(shè)備規(guī)格就越大，工藝也越復(fù)雜，投資自然越高。第二個(gè)是提純工藝選擇，不同工藝的成本差異很大，比如之前提到的高壓水洗法、膜分離法、生物脫硫提純法等，膜分離法設(shè)備前期投入相對(duì)高一些，高壓水洗法后期運(yùn)行成本有優(yōu)勢(shì)，選擇不同工藝會(huì)直接改變總投資。

　　After understanding the approximate investment scope, let's talk about which factors will directly affect the investment cost. The first key factor is the scale of aquaculture and biogas production, which are the basis for determining costs - the larger the scale and the more gas produced, the larger the required purification equipment specifications, the more complex the process, and naturally the higher the investment. The second is the selection of purification processes, and the cost of different processes varies greatly. For example, the high-pressure water washing method, membrane separation method, biological desulfurization purification method, etc. mentioned earlier have relatively higher initial investment in membrane separation equipment, while high-pressure water washing method has advantages in later operating costs. Choosing different processes will directly change the total investment.

　　第三個(gè)因素是設(shè)備選型，是選國(guó)產(chǎn)設(shè)備還是進(jìn)口設(shè)備，選常規(guī)配置還是智能高配，成本差距明顯。現(xiàn)在國(guó)產(chǎn)沼氣提純?cè)O(shè)備技術(shù)已經(jīng)很成熟，性價(jià)比很高，大部分豬場(chǎng)選國(guó)產(chǎn)設(shè)備就能滿足需求；如果追求更高的穩(wěn)定性和自動(dòng)化程度，選進(jìn)口設(shè)備或智能高配，成本可能會(huì)增加30%以上。第四個(gè)因素是項(xiàng)目用途，前面也提到過(guò)，自用發(fā)電的簡(jiǎn)化工藝成本低，要對(duì)外銷售生物天然氣或接入管網(wǎng)，就需要達(dá)到更高的純度標(biāo)準(zhǔn)，必須配套更完善的提純和檢測(cè)設(shè)備，成本會(huì)相應(yīng)增加。

　　The third factor is equipment selection, whether to choose domestic or imported equipment, whether to choose conventional configuration or intelligent high-end configuration, the cost difference is obvious. Nowadays, the technology of domestic biogas purification equipment is very mature and cost-effective. Most pig farms can meet their needs by choosing domestic equipment; If pursuing higher stability and automation, choosing imported equipment or intelligent high-end configurations may increase costs by more than 30%. The fourth factor is the project purpose. As mentioned earlier, the simplified process cost for self use power generation is low. To sell bio natural gas or connect it to the pipeline network, higher purity standards need to be achieved, and more complete purification and testing equipment must be provided, which will increase the cost accordingly.

　　可能有豬場(chǎng)經(jīng)營(yíng)者會(huì)覺(jué)得，這個(gè)投資成本不低，到底值不值得？其實(shí)要算長(zhǎng)遠(yuǎn)賬，沼氣提純后的生物天然氣用途廣泛，能自用發(fā)電、供暖，也能對(duì)外銷售，還能享受國(guó)家可再生能源補(bǔ)貼政策。而且豬場(chǎng)糞污經(jīng)過(guò)厭氧發(fā)酵產(chǎn)生沼氣，再提純利用，既能解決糞污污染問(wèn)題，又能降低能源成本，形成“養(yǎng)殖-沼氣-能源”的循環(huán)模式，長(zhǎng)期來(lái)看經(jīng)濟(jì)效益和環(huán)保效益都很可觀。比如大型豬場(chǎng)如果把提純后的生物天然氣接入管網(wǎng)銷售，一般3到5年就能收回投資。

　　Some pig farm operators may think that this investment cost is not low, is it worth it or not? In fact, in terms of long-term accounting, the purified biogas from biogas has a wide range of uses, including self use for power generation and heating, as well as external sales, and can also enjoy national renewable energy subsidy policies. Moreover, pig farm manure undergoes anaerobic fermentation to produce biogas, which is then purified and utilized. This not only solves the problem of manure pollution, but also reduces energy costs, forming a "breeding biogas energy" cycle. In the long run, both economic and environmental benefits are considerable. For example, if a large pig farm connects purified biogas to the pipeline for sale, the investment can generally be recovered within 3 to 5 years.

　　總結(jié)下來(lái)，現(xiàn)代化養(yǎng)豬場(chǎng)沼氣提純投資，中小型（5000-10000頭存欄）大概200萬(wàn)-500萬(wàn)元，大型（1萬(wàn)-5萬(wàn)頭以上存欄）大概500萬(wàn)-1500萬(wàn)元，具體成本要根據(jù)養(yǎng)殖規(guī)模、沼氣產(chǎn)量、工藝選擇和項(xiàng)目用途來(lái)定。建議豬場(chǎng)在規(guī)劃項(xiàng)目時(shí)，先測(cè)算自身的糞污產(chǎn)量和沼氣潛力，再明確項(xiàng)目用途（自用還是外銷），然后找專業(yè)廠家定制方案，這樣才能精準(zhǔn)控制投資成本。如果只是想解決糞污問(wèn)題并自用能源，不用盲目追求高投入；如果有外銷生物天然氣的規(guī)劃，再針對(duì)性提升工藝和設(shè)備配置。總的來(lái)說(shuō)，沼氣提純投資是現(xiàn)代化養(yǎng)豬場(chǎng)綠色轉(zhuǎn)型的重要投入，選對(duì)方案就能實(shí)現(xiàn)環(huán)保和盈利的雙贏。

　　In summary, the investment in biogas purification in modern pig farms is approximately 2-5 million yuan for small and medium-sized (5000-10000 heads in stock) and 5-15 million yuan for large (10000-50000 heads or more in stock). The specific cost depends on the scale of breeding, biogas production, process selection, and project use. It is recommended that pig farms first calculate their own manure production and biogas potential when planning projects, then clarify the project purpose (self use or export), and then find professional manufacturers to customize solutions, so as to accurately control investment costs. If you only want to solve the problem of manure and use your own energy, there is no need to blindly pursue high investment; If there is a plan to export bio natural gas, then improve the process and equipment configuration accordingly. Overall, investment in biogas purification is an important investment for the green transformation of modern pig farms. Choosing the right solution can achieve a win-win situation of environmental protection and profitability.
