養(yǎng)殖場業(yè)可以利用沼氣發(fā)電嗎？

沼氣能源建設（沼氣提純），一方面可以補充農(nóng)村生產(chǎn)生活的能源需求;另一方面，可以減少工業(yè)生產(chǎn)中有機廢水和生活垃圾對環(huán)境造成的危害。沼氣發(fā)電綜合利用環(huán)境保護與節(jié)能相結(jié)合的新技術。它利用工業(yè)、農(nóng)業(yè)和城市生活中大量的有機廢用物，以及氧氣發(fā)酵產(chǎn)生的沼氣來驅(qū)動沼氣發(fā)電機組。同時，充分利用發(fā)電機組的余熱生產(chǎn)沼氣。綜合熱效率在80%以上，高于一般發(fā)電效率的30%-40%。經(jīng)濟效益顯著。直接的優(yōu)點是解決了用電問題，節(jié)約了用電成本。例如，一個一年飼養(yǎng)2000頭以上種豬的養(yǎng)豬場，需要使用飼料粉碎機、攪拌機、冬季對仔豬的保溫以及培養(yǎng)箱。過去一年里，平均每月的電力支出超過5000元。使用沼氣發(fā)電意味著它可以節(jié)省大量的電力成本。

Biogas energy construction can supplement the energy demand of rural production and life on the one hand; On the other hand, it can reduce the harm to the environment caused by organic wastewater and domestic waste in industrial production. Comprehensive utilization of biogas power generation is a new technology combining environmental protection and energy saving. It uses a large number of organic wastes in industry, agriculture and urban life, as well as biogas produced by oxygen fermentation to drive biogas generator sets. At the same time, make full use of the waste heat of the generator set to produce biogas. The comprehensive thermal efficiency is more than 80%, which is higher than 30% - 40% of the general power generation efficiency. Remarkable economic benefits. The most direct advantage is that it solves the problem of power consumption and saves the cost of power consumption. For example, a pig farm that raises more than 2000 breeding pigs a year needs to use feed crushers, mixers, heat preservation of piglets in winter and incubators. In the past year, the average monthly electricity expenditure exceeded 5000 yuan. Using biogas to generate electricity means that it can save a lot of power costs.

其次，它有助于減少農(nóng)場污染。對于養(yǎng)豬場來說，麻煩的問題是豬糞和污水處理。然而，沼氣發(fā)電可以很好地解決這些污染物。來自養(yǎng)豬場的糞便和污水可以進入沼氣池，由一根管道輸入。沼氣池排出的沼氣液可用于清潔豬圈，實現(xiàn)循環(huán)養(yǎng)殖模式，降低污染風險。沼氣發(fā)電還可以產(chǎn)生額外的經(jīng)濟效益。例如，投資30萬元，容量500立方米的沼氣池和50千瓦發(fā)電機，一年可生產(chǎn)沼氣5.2萬立方米，發(fā)電7.5萬度，年產(chǎn)沼氣渣和沼氣漿4000噸，經(jīng)濟效益15萬元。

Second, it helps reduce farm pollution. For pig farms, the most troublesome problems are pig manure and sewage treatment. However, biogas power generation can solve these pollutants well. Feces and sewage from pig farms can enter the biogas digester and be input by a pipe. The biogas liquid discharged from the biogas digester can be used to clean the pigsty, realize the circular breeding mode and reduce the pollution risk. Biogas power generation can also produce additional economic benefits. For example, with an investment of 300000 yuan, a biogas digester with a capacity of 500 cubic meters and a 50 kW generator can produce 52000 cubic meters of biogas a year, generate 75000 kwh of power, produce 4000 tons of biogas residue and biogas slurry a year, and achieve an economic benefit of 150000 yuan.
沼氣提純

沼液和沼渣中含有多種氨基酸、生長素、抗生素和多種微量元素，可作肥料利用、飼養(yǎng)利用、生物農(nóng)藥、培養(yǎng)料液等。沼液可作為有機肥料灌溉到農(nóng)田中或者直接噴灑到植物葉面作葉面肥，既能增加作物產(chǎn)量、提高產(chǎn)品品質(zhì)，又能增強作物的抗逆性;可用作飼料添加劑，使豬提前出欄、肉質(zhì)提高，雞產(chǎn)蛋率提高;可進入魚塘促進浮游生物的生長，是魚的良好餌料，使魚的產(chǎn)量提高、抗病性增強;可用于浸種，提高種子的出芽率和以后的生長能力;可作為無毒、無殘留的農(nóng)藥來防治農(nóng)業(yè)病蟲害。

Biogas slurry and biogas residue contain a variety of amino acids, auxin, antibiotics and trace elements, which can be used as fertilizer, feeding, biological pesticide, culture material, etc. Biogas slurry can be used as organic fertilizer to irrigate farmland or directly sprayed on plant leaves as leaf fertilizer, which can not only increase crop yield and improve product quality, but also enhance crop stress resistance; It can be used as feed additive to make pigs go out of the market in advance, improve meat quality and improve chicken egg laying rate; It can enter the fish pond to promote the growth of plankton. It is a good bait for fish, which improves the yield and disease resistance of fish; It can be used for soaking seeds to improve the germination rate and future growth ability of seeds; It can be used as a non-toxic and residue free pesticide to control agricultural diseases and pests.
