在“”、“十一五”、“十二五”期間,預(yù)算內(nèi)投資先后安排超過(guò)300億元,支持農(nóng)村戶用沼氣發(fā)展。
During the period of "the Tenth Five Year Plan", "the Eleventh Five Year Plan" and "the Twelfth Five Year Plan", more than 30 billion yuan has been invested in the central budget to support the development of rural household biogas.
隨著城鎮(zhèn)化的快速推進(jìn)和農(nóng)業(yè)生產(chǎn)方式、農(nóng)村居住方式、農(nóng)民用能方式的變化,農(nóng)村戶用沼氣的正常使用和持續(xù)發(fā)展問(wèn)題日益突顯,缺少后續(xù)投入,沼氣技工加速流失,配套服務(wù)失去保障,眾多農(nóng)村戶用沼氣出現(xiàn)建而不用,閑置荒廢等諸多問(wèn)題,無(wú)法持續(xù)發(fā)揮效益,造成了財(cái)政資金浪費(fèi)。
With the rapid development of urbanization and the changes of agricultural production mode, rural residential mode and farmers' energy use mode, the problems of normal use and sustainable development of rural household biogas are increasingly prominent, such as the lack of follow-up investment, the accelerated loss of biogas technicians, the loss of supporting services, many rural household biogas problems such as construction without use, idle waste and so on, which cannot continue to play their benefits , causing a waste of financial funds.
從分散式家庭制沼氣到集約化處理畜禽糞污,規(guī)模化沼氣工程需求日益增長(zhǎng),尤其是以沼氣提純?yōu)榉较虻墓I(yè)化生物天然氣是未來(lái)發(fā)展的。沼氣經(jīng)提純后的生物天然氣與化石天然氣在燃料屬性上幾乎沒(méi)有差異,具有高價(jià)值、率、易接入的特點(diǎn),是對(duì)農(nóng)村戶用沼氣和傳統(tǒng)沼氣工程的優(yōu)化升級(jí)。此外,生物天然氣的沼液沼渣等副產(chǎn)物可用于生產(chǎn)有機(jī)肥,能夠改良土壤、培肥地力、增加農(nóng)作物產(chǎn)量與農(nóng)產(chǎn)品質(zhì)量,加快有機(jī)肥推廣應(yīng)用,替代化肥,是推動(dòng)農(nóng)業(yè)綠色發(fā)展的重要舉措。加快推進(jìn)生物天然氣產(chǎn)業(yè)化發(fā)展,對(duì)于實(shí)現(xiàn)循環(huán)農(nóng)業(yè)、促進(jìn)畜禽糞污資源化利用、治理農(nóng)村人居環(huán)境、增加可再生能源消費(fèi)、降低天然氣對(duì)外依存度、解決北方地區(qū)冬季清潔取暖等多個(gè)方面具有積極作用。
From decentralized household biogas to intensive treatment of livestock and poultry manure, the demand for large-scale biogas projects is growing day by day, especially the industrial bio natural gas with biogas purification as the direction is the focus of future development. There is almost no difference in fuel properties between the purified biogas and fossil natural gas, which has the characteristics of high value, high efficiency and easy access. It is the optimization and upgrading of rural household biogas and traditional biogas projects. In addition, biogas byproducts such as biogas slurry and biogas residue can be used to produce organic fertilizer, which can improve soil and fertility, increase crop yield and quality of agricultural products, accelerate the application of organic fertilizer, and replace chemical fertilizer, which is an important measure to promote the green development of agriculture. Accelerating the industrialization of biological natural gas will play a positive role in realizing circular agriculture, promoting the utilization of livestock and poultry manure resources, harnessing the rural living environment, increasing the consumption of renewable energy, reducing the dependence of natural gas on foreign countries, and solving the problem of clean heating in winter in northern China.
