在“”、“十一五”、“十二五”期間,預算內投資先后安排超過300億元,支持農村戶用沼氣發展。
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.
隨著城鎮化的快速推進和農業生產方式、農村居住方式、農民用能方式的變化,農村戶用沼氣的正常使用和持續發展問題日益突顯,缺少后續投入,沼氣技工加速流失,配套服務失去保障,眾多農村戶用沼氣出現建而不用,閑置荒廢等諸多問題,無法持續發揮效益,造成了財政資金浪費。
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,規模化沼氣工程需求日益增長,尤其是以沼氣提純為方向的工業化生物天然氣是未來發展的。沼氣經提純后的生物天然氣與化石天然氣在燃料屬性上幾乎沒有差異,具有高價值、率、易接入的特點,是對農村戶用沼氣和傳統沼氣工程的優化升級。此外,生物天然氣的沼液沼渣等副產物可用于生產有機肥,能夠改良土壤、培肥地力、增加農作物產量與農產品質量,加快有機肥推廣應用,替代化肥,是推動農業綠色發展的重要舉措。加快推進生物天然氣產業化發展,對于實現循環農業、促進畜禽糞污資源化利用、治理農村人居環境、增加可再生能源消費、降低天然氣對外依存度、解決北方地區冬季清潔取暖等多個方面具有積極作用。
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.
