reporter today from the Ji'nan Municipal Finance Bureau was informed that, since 11th Five-Year, Ji'nan has invested 230 million 470 thousand yuan in financial funds to help promote the construction of new rural ecological energy. Up to now, the number of rural household biogas digesters in rural areas has been covered by 190 thousand households, and 414 large-scale livestock farm biogas projects have been built, more than 60 "three marsh" comprehensive utilization demonstration bases or ecological recycling agricultural demonstration parks and more than 400 high standard ecological civilization demonstration villages have been built.
190 thousand biogas pool annual expenditure increased by 600 million yuan
in recent years, Ji'nan city through the project led new households to use 160 thousand households with biogas digesters, rural household biogas digesters have exceeded 190 thousand households, accounting for 38% of the number of farmers in the city. It is estimated that the annual coal consumption of a methane user is about 1500 kg, and the electricity saving is 600 degrees. The 190 thousand household biogas digesters in the city can reduce the amount of coal consumption by 285 thousand tons and reduce the electricity consumption by more than 100 million degrees each year. Each "one pool three changes" (the construction of the biogas pool as the core to implement the modification, the kitchen change and the toilet) saves about 1500 yuan of energy expenditure and uses the biogas per year. The farmers' income in the production of organic agricultural products by slag and biogas liquid is nearly 2000 yuan per year. If the city's household biogas can be fully exploited and utilized, the annual expenditure is more than 600 million yuan.
the development of rural biogas can significantly reduce carbon dioxide emissions in rural areas, reduce the amount of chemical fertilizers and pesticides in agricultural production, and effectively control the pollution of the manure of livestock and poultry farms to the underground water and the surrounding environment. At present, 414 kinds of biogas projects in large-scale livestock and poultry farms have been built in the city, and more than 330 tons of feces are treated annually, which effectively promotes the pollution control of agricultural non-point sources, and has realized the resource utilization of waste of livestock and poultry excrement in some farms.
220 thousand mu
how to extend the industrial chain of biogas development to achieve the best use of biogas, biogas slurry and biogas residue? Our city combines the comprehensive utilization of "three marsh" with the construction of agricultural characteristic brand base to produce biogas and marsh by fermenting the excrement of livestock in the biogas pool. Liquid and biogas residue are used to meet the common needs of farm day, and biogas slurry and biogas residue are used as high quality fertilizer for fruit and vegetable bases, and a virtuous cycle of "aquaculture - biogas - planting" is formed to promote the development of circular agriculture with biogas as the link.
at present, the city has built the Zhangqiu city of embroidery Hui town Organic Onion base, Changqing Wan Sheng Yuan ecological recycling agricultural demonstration base, and other "three marsh" comprehensive utilization demonstration base or ecological recycling agricultural demonstration park more than 60 places, to promote "one shed one pool", "Trinity", "animal - Marsh - fruit (vegetable)" and other ecological agriculture The production area is 220 thousand mu.
the construction of more than 400
rural household biogas digesters in the city of ecological civilization is built to liberate farmers from the messy environment, such as "haystack, dung heap, garbage pile", smoked fire, and mosquitoes and flies. The sanitary and clean biogas has changed the environment of smoking and burning in the countryside. To change the toilet and change the circle, the farmers can also use the water to wash the toilet and take a hot bath like the city dwellers. Up to now, the city has built more than 400 high standard ecological civilization demonstration villages, such as Le Jia Village in Zhangqiu, Zhao he village in the calendar district and Shi Wo Village in Changqing District, to promote the promotion and installation of more than 5.6 million solar water heaters.
in order to improve the development and utilization of biogas, 451 rural biogas service organizations were built in the city, and 310 biogas fertilizer production trucks and 100 straw shredders were equipped, with more than 150 thousand users of Biogas Service, and the coverage rate of Biogas Service reached 79%. At present, our city has carried out the pilot work of regional service organization, exploring the operation mode of regionalized biogas service, promoting the operation mechanism of Biogas Service Organization in the whole city, and consolidating the achievements of biogas construction.
