Twenty years，Professor Liu Kefeng leads the research team to work with feces all day long，Combined with pig breeding in Beijing、Cow、Chicken、Characteristics of more ducks，Conquered the pigs one after another、Cow、Sheep、Chicken、Difficulties in technical treatment of duck and other livestock and poultry manure，Pig manure processed、Cow dung、Sheep dung、Chicken manure and duck manure solid、Contamination caused by large-scale accumulation of liquid feces，Effectively improve the rural environment and soil、Water system pollution，Produces high-quality organic fertilizer and cultivation substrate，Promotes the development of circular agriculture。Shunyi in Beijing、Tongzhou、Yanqing、Mentougou、Inner Mongolia、The research results of Liu Kefeng’s team are applied in many large-scale breeding communities in Yunnan and other places，Effectively improve the local ecological environment。
The deeds of Professor Liu Kefeng and his research team have attracted the attention of many media。Recently，Guangming Daily、China Educational Television、People's Daily Online、Chinese Science Journal、Modern Education News、Beijing Times、Sina、Tencent and other media have concentrated reports on Professor Liu Kefeng,At the same time，Reprinted by many online media。China Education News、Science and Technology Daily、Farmers Daily will also report on it in the near future。This article is excerpted from reports by Guangming Daily and China Educational Television。
“A good university professor，Why do you dig into the excrement pile all day long！”
Faced with such a problem，Liu Kefeng, a professor at Beijing Agricultural College, always smiles lightly: "Just get used to it！”From research on waste classification，To study livestock and poultry manure treatment，Liu Kefeng has been working for 20 years。
Speaking of the "affiliation" with feces，58 years old this year、Wearing high bet365 online sports betting livemyopia glasses、The elegant and restrained Liu Kefeng confessed: “I originally studied soil fertilizers。”1993，Beijing Chaoyang District Environmental Sanitation Bureau found him，I hope Liu Kefeng can help them solve the problem of garbage classification and processing。No one wanted to engage in this field at that time，Tired and smelly。Liu Kefeng brought Wang Hongli、Two young teachers Shi Aiping，Take samples for testing in the garbage dump，One squat is a day。“My wife won’t let me into the house once I get home，Stinky all over，Cannot be washed off。”However，It is the research result of Liu Kefeng’s team for many years，Provided scientific support for Beijing to formulate garbage classification standards。
Beilangzhong Village in Shunyi District is known as the “No. 1 pig-raising village in the suburbs of Beijing”。Recently，Reporters visit here，Fragrance of flowers and grass，Little bridge and flowing water，Pleasant environment。Who would have thought，more than ten years ago，There are piles of pig manure everywhere，Flies everywhere，Sewage flows everywhere。1997，Find Liu Kefeng in Beilang Zhongcun，I hope he can solve the problem of pig manure pollution and utilization。Liu Kefeng and his team live and eat in the village，Sometimes to measure a parameter，He and his colleagues squatted in the pig manure pile for several hours，Stinky when I came out。He recalled: “Every time I take the bus back to school from the village，The driver will tell me when he sees him，Come up once，My car will stink for several days！”
It is accompanied by a dung pile half as tall as a man，Liu Kefeng and his team have overcome every problem in converting pig manure into organic fertilizer，Not only dealt with all the feces in Beilangzhong Village，Also helped build a fertilizer plant，Fertilizer is applied to farmland again，Effective loop implemented。Today，Beilangzhong Village has become “the most beautiful village in Beijing”。
The same thing happened in Dabai Village, Yanqing County.
2008，Ma Yongcun, the old village party secretary of Dabai who just took office, pondered: There are more than 10,000 cows in the village，Although the villagers’ income has increased，But how to deal with the cow dung all over the village？What’s even more worrying is，The accumulated cow dung has begun to affect the local water quality and bet365 online sports betting appsoil。Yanqing County is located in a favorable location，If the water quality、The air is polluted by cow dung，Beijing’s drinking water and environment will also be seriously affected。
At that time, Beijing Agricultural College and Yanqing County cooperated to launch the “1+1+X” science and technology training project，Ma Yongcun found Liu Kefeng。Talk about the feeling of coming to Dabai Old Village for the first time，Liu Kefeng was still deeply impressed: “It was winter when I went there，It was windy that day。As soon as you enter the village，I saw yellow powder flying all over the sky，From a distance, I thought it was dust and yellow sand，When I walked in, I realized it was powdered cow dung。”
However，The composition of pig manure and cow manure is very different，Bacteria added when producing organic fertilizer、The temperature parameters during fermentation need to be re-explored and tested。Recalling the process of studying cow dung，Teacher Wang Hongli laughed loudly: “There is no fresh cow dung in the village，Let’s just take the big shovel，Squatting behind the cow’s butt and waiting，Waiting eagerly for the steak to be eaten，Finally caught a shovelful of steaming cow dung，You have to hurry up and do the experiment。”
Livestock and poultry feces pollution is a problem that plagues the world's environment，Beijing and surrounding areas alone produce more than 1 billion tons of livestock and poultry manure every year。What Liu Kefeng’s team is proud of，20 years，They combine the characteristics of breeding in Beijing，Conquered the pigs one after another、Cow、Sheep、Chicken、Difficulties in technical treatment of duck and other livestock and poultry manure，Established with independent intellectual property rights、Collect livestock and poultry manure、A process technology system that integrates wastewater treatment and in-depth development and utilization of fecal resources，Effectively improve the rural environment、Soil and water pollution，Let the livestock and poultry breeding industry embark on the development path of circular agriculture。
Liu Kefeng said frankly: “Some foreign technologies are really good，We also introduced it，But it’s not acclimatized in China，The price is too expensive，Energy consumption is too high。Technology and equipment developed by bet365 online casinous，Low cost，Low energy consumption，More suitable for localized breeding industry needs。”Currently，The research results of Liu Kefeng’s team have been in Shunyi, Beijing、Tongzhou、Yanqing、Large-scale applications and demonstrations in Mentougou and other places，and promoted to Inner Mongolia、Dozens of large-scale breeding communities in Yunnan and other areas，Produced more than 1 million tons of high-quality organic fertilizer，The total economic benefit reaches 2 billion yuan。(our reporter Zhang Jinghua)
