最近,本刊就我国小型沼气池技术发展动向问题走访了农业部成都沼科所副所长、副研究员熊承永同志。现将谈话整理发表如下(未经本人审阅)。记者:突然来打搅您,请原谅。我们希望知道我国农村小型沼气池技术的发展情况,可以简单介绍一下吗?熊承永:我国农村小型沼气池的发展,在70年代有过大起大落。到80年代初期,主要抓了三项技术,即发酵工艺、建池技术和与之配套的装置,如管道、阀门等等。在此基础上发展起来的小型沼气池,就是以《中国水压式沼气池标准图集》为代表的池型,比较规范化。虽然当时沼气池的经济效益还不是很合算,但技术上没什么问题,是技术进步的标帜。所谓 Recently, this magazine visited China’s small biogas technology development trends to visit the Ministry of Agriculture Chengdu Bike Institute deputy director, associate researcher Comrade Xiong Chengyong. The following is a summary of the conversation (without my review). Reporter: Suddenly to disturb you, please forgive me. We would like to know about the development of small-scale biogas digesters in rural areas in China. Can we briefly introduce Xiong Chengyong: The development of small-scale biogas digesters in rural areas in our country was greatly ups and downs in the 1970s. By the early 1980s, three major technologies were grasped, namely, fermentation technology, pool-building technology and associated facilities such as pipes, valves and the like. On this basis, the development of small-scale biogas digesters is based on the “China Hydrological Digester Standard Atlases” as the representative of the pool, more standardized. Although the economic benefits of digesters were not yet very cost-effective at the time, they were technically sound and were the flags of technological progress. So-called
