Want to know the advantages and disadvantages of commonly used energy now, only poor methane, and hope to get the answer, thank you
Save rural energyBiogas can be used for heating, cooking, lighting, heating, bathing. A family of five, built a 8 cubic meters of methane pool, can cook for the whole family for 8 months and a year of illumination, plus auxiliary heating, can also take a bath, the annual coal saving 4000 kg, saving 350-400, two value of 550 yuan or so, no electricity in mountainous areas where can save 10 to 15 kilograms of kerosene
Improve fertilizer efficiencyHuman and animal feces, miscellaneous apples, organic waste, in ordinary pit retting, due to open pit, wind, sun and rain, the most volatile nutrient loss, and not easy to be absorbed by crops, if after digesters sealed after fermentation, most nutrients preserved, and became soluble nutrients, easy by using the history of crop uptake of JI. People said: biogas slurry looks like water, like ammonia, but also to increase the soil humus, play a role in improving the soil.
Promote aquaculture developmentThe construction of biogas digesters can not only effectively solve the sewage problem of livestock and livestock manure into the pond after fermentation produces biogas slurry and a small amount of Potassium Permanganate, is the finest pig fodder. Because the biogas slurry contains a variety of trace elements, especially the amino acid content is very rich, and are soluble nutrients, easy digestion and absorption. Using biogas slurry to raise pigs, each year can save 40 kg of refined shaking, but also shorten the feeding period of 15 - 25 days, thereby reducing costs.
Improve rural health conditionsWith the development of animal husbandry to intensive breeding, waste matter, livestock and poultry carcasses, feather and slaughter water increased year by year, plus home toilet stool, crop to skewer, organic wastes, traditional composting, landfill, incineration, washing and other measures are not effective, especially in pigs and chickens, the mosquitoes a large number of flies, one summer, not only caused serious pollution of groundwater, soil, rivers, and with a large number of pathogens, endanger human and animal disease and animal health and quality. If they are closed through the biogas digesters, can effectively kill a variety of egg germs, so as to effectively deal with these waste, to maintain clean rural environment, reduce air pollution and disease.
