OA show ('918 '); according to the report of "new trend" technology on November 26, the University of Florida in the United States sent good news After four years of intensive research, they finally successfully developed a set of new systems With the help of this technology, dairy farms will no longer emit unpleasant smell all day, but will be replaced by rose fragrance In the past, thousands of cows were raised in dairy farms, which inevitably gave off a bad smell In addition, with the continuous expansion of the city, the distance between residents and farms is getting closer and closer As a result, the contradiction between farms and ordinary residents' home life has erupted irresistibly Now, researchers from the University of Florida's dairy research department have finally developed an anaerobic digestion system that can eliminate the stench of farms, and the conflict between residents and farms is expected to be resolved According to the researchers, the anaerobic digestion system is jointly developed by the Department of soil hydrology, the Department of animal science, the Department of agricultural science and the Department of bioengineering, and is the product of cooperation among various disciplines In short, its working principle is to use the microorganism in the anaerobic digester to transform the odor causing components in the waste discharged from poultry into methane and carbon dioxide, so that the waste no longer emits the disgusting smell This principle has been applied in medicine, alcohol purification and other aspects for a long time, but it is the first time to use it in farms I hope this system can really help people get rid of the smell of the farm BP3 (author:)
