On February 9th, with the buzz of a bang, the gas stove of Li Guowen, a villager in Dali Village, Pu'an Township, Yibin County, picked up a fiery blue flame. Li Guowen told reporters unhappily: "We used to burn firewood, and cooking and boiling water had been suffocated with a tearful nose. Especially in the summer, nobody wanted to work in the kitchen. Now we use methane to cook. When it is time to save money and save money, the benefits are very much."
Li Guowen used straw and bran to feed six pigs, then used pig manure and domestic wastewater as raw materials to produce biogas, provided fuel and lighting for the home, and finally poured the biogas liquid residue into the field as fertilizer.
Like Li Guowen, there are still many farmers in Yibin County who realize the benefits of using biogas. In recent years, Yibin County has taken the biogas digester project as an important measure to improve the production and living conditions of rural households and the rural ecological environment. It is relying on rural biogas debt projects and provincial biogas projects to vigorously popularize rural biogas. As of the end of 2010, the county built a total of 51032 pools, accounting for 36.1% of the construction users.
The benefits of biogas are endless. "In the past, using fireweed to cook smoked food, people were uncomfortable and uncomfortable. Now that they have used biogas, they can turn on the switch, saving time, convenience, and saving money. Comfortable, the home is more tidy and clean than before.†Liao Xintian, villager of Yijie County, Yijie County, said with joy.
In Liao Xintian’s kitchen, the reporter saw that the white tiles were clean and the pots and pans were neatly arranged; the pigs and chickens were all in the circle, the pig manure all flowed into the digester, and the toilets were changed. Into the water, "I used to see people in the city using natural gas, flush toilets, and water heaters. I'm very envious of them. Now we use them as well. The yards are clean and the pigs don't smell bad again. Taste. This day, ah, nourishing!" Speaking of the benefits of biogas, Liao Xintian is a few treasures.
Saving energy and low-carbon “A biogas digester is a 'money pot'.†Zhang Yong, a farmer in Yibin County, calculated the account: A household biogas digester produces 380 cubic meters of gas each year. Provide 80% of household energy for farmers, reduce fuel costs 500-1200 yuan, biogas slurry, biogas residue can meet the fertilizer needs of 3 acres of land, but also can save more than 1200 yuan of fertilizers, pesticides, agricultural resources, inside and outside One year can save more than 2,000 yuan, plus the benefits of raising pigs, biogas digesters became the people's money cans.
"Using biogas not only conforms to the current concept of energy saving and recycling, 'low-carbon' development, making the environment cleaner, but also has the effect of preventing and controlling schistosomiasis and soot-type fluorosis after the establishment of a biogas digester." Biogas digesters can replace 2,500 kilograms of diesel fuel each year to reduce soil loss by 1.19 tons, equivalent to a biomass reserve of 3.5 acres of charcoal forest.
Promoting the industrialization of biogas projects has not only brought convenience and benefits to the villagers, but has also given a new look to the village. It has also promoted the adjustment of agricultural structure, prolonged the biological chain, increased the utilization of resources, and became a new growth point for the rural economy.
“Manure produced biogas, biogas is used for cooking, biogas digesters are used as fertilizer, and various ecological models such as 'pig-mung-food', 'pig-marsh-fruit' and 'rabbit-marsh-mulberry' are created. The circular economy with biogas as the link has stimulated the aquaculture industry, adjusted the planting structure, and realized the chain effect of farmers' homes.†Li Yunhe, the new branch of the village party secretary, told reporters that the biogas was linked to the aquaculture industry and the joint planting industry promoted The development of the ecological aquaculture industry and the highly efficient planting industry has fundamentally changed the traditional way of manure usage and the agricultural development mode of excessive application of pesticides and fertilizers.
Supervise and re-energize "Enthusiasm"
"Three points to build, seven points." With the continuous expansion of the construction scale, the problem of “heavy construction and light management†in the construction of rural biogas has become increasingly apparent, which has greatly affected the full play of the comprehensive benefits of biogas digesters, and to a certain extent hinders the popularization and utilization of biogas digesters in rural areas. In order to establish an effective management and long-term operation mechanism, and to take advantage of the comprehensive benefits of biogas, the county regularly organizes technical personnel to conduct large-scale return visits. It does not carry out normal gas production, does not normally import and export materials, and does not carry out comprehensive utilization or utilization of “three marshes†or technology. Not in place, on-site technical guidance; the establishment of Yibin County biogas property service station, in the county township of 26 sets up township biogas property service sub-station, in the administrative village of biogas users set up village-level service outlets, improve the county, township, village The third-tier rural biogas service system; in May 2010, the county farm energy office actively sought more than 1.1 million yuan of special funds to purchase 33 biogas service vehicles and distribute it to 26 township biogas service stations.
“In the past, pig manure and chicken excrement were everywhere on the small road. After the biogas was used, these excrements became 'baby' and the villagers stayed in their own homes.†Chen Jiang, University Student Village Officer, Xinlian Village, Xijie Town, Xinlian Village A total of 481 households have built 261 biogas tanks. Now that the environment in the village is much better, it is really 'the scenery in front of the house, the biogas reservoir next to the toilet, and the clean room in the courtyard is bright, but the smell of rice is not seen. '"
The small biogas digesters not only solved the problem of cooking energy, improved the home environment in rural areas, eliminated the breeding grounds for mosquitoes and flies, but also stimulated the breeding industry, promoted the pollution-free production of planting and agricultural products, and realized the recycling of livestock and poultry manures. , Home warming and cleanliness, harmlessness of agricultural production, efficient courtyard economy, effective prevention and control of schistosomiasis and other diseases and diseases, raising rural health and health standards, and bringing new life to the majority of farmers.
