自2011年以来,山东省狠抓沼气为主的农村能源建设项目配套实施,对大中型规模化畜禽养殖场,将沼气生产、有机肥料生产和养殖污染物处理有机结合在一起,推行养殖区集中治污;在农村小规模养殖场建设生态型沼气工程,解决燃料、肥料、饲养矛盾。建设各类沼气池容积达2万立方米,新建的规模化养殖场全部配套建设粪便处理区,实现养殖污染物处理后还田,无直接排放现象发生,大大保护了周边环境,养殖沼气脱硫后综合利用,可取暧、照明、发电、做饭等,每年可节约6000吨标准煤。
Since 2011, Shandong Province has paid close attention to the implementation of biogas based rural energy construction projects. For large and medium-sized livestock and poultry farms, biogas production, organic fertilizer production and breeding pollutant treatment are organically combined, and centralized pollution control in breeding areas is implemented; Ecological biogas project should be built in small-scale farms in rural areas to solve the contradiction of fuel, fertilizer and feeding. The capacity of all kinds of biogas digesters is up to 20000 cubic meters, and the newly-built large-scale breeding farms are all equipped with manure treatment areas, so as to realize the return of breeding pollutants to the field after treatment, without direct emission, which greatly protects the surrounding environment. After desulfurization, the breeding biogas can be comprehensively utilized, such as heating, lighting, power generation, cooking, etc., saving 6000 tons of standard coal per year.
养殖畜禽粪便转化产沼气是目前比较成熟的畜禽粪便能源化技术,改善原料可利用性,提高微生物的数量和活性,是提高沼气发酵效率的有效措施,大型沼气工程不在示范探索期,全产业链各环节所存在的诸多问题仍待解决。
Biogas production from livestock manure is a relatively mature energy technology at present. Improving the availability of raw materials and increasing the number and activity of microorganisms are effective measures to improve the efficiency of biogas fermentation. Large scale biogas project is not in the demonstration period, and many problems in the whole industrial chain still need to be solved.
大力发展农业循环经济,加大沼气转换技术是解决农村污染的重要手段。沼气提天然气作为一种清洁的分布式能源,可替代石化天然气,用于车用燃料、居民燃气,是沼气高值化、能源化利用的重要方式,发展农村沼气,实现养殖畜禽粪便的资源化利用对开发农村清洁能源、防治农村大气污染、促进生态循环农业发展、改善农村人居环境、巩固生态环境建设成果都有十分重大的意义。
It is an important way to solve rural pollution to develop agricultural circular economy and increase biogas conversion technology. As a kind of clean distributed energy, biogas extracted natural gas can replace petrochemical natural gas and be used as vehicle fuel and residential gas, which is an important way of high value and energy utilization of biogas. The development of rural biogas and the realization of resource utilization of livestock manure are of great significance to the development of rural clean energy, the prevention and control of rural air pollution, and the promotion of the development of ecological circular agriculture It is of great significance to improve the rural living environment and consolidate the achievements of ecological environment construction.
开发利用农村养殖沼气完全符合产业兴旺、生态宜居、乡风文明、治理有效、生活富裕的总体要求,具有广阔的发展空间。
The development and utilization of biogas in rural areas is fully in line with the overall requirements of industrial prosperity, ecological livability, rural civilization, effective governance and affluent life, and has broad development space.
