沼气作为可再生能源的重要组成部分,沼气在我国广大乡村区域现已走过了数十年的发展历程。数据显现,目前全国沼气用户已达到上千万户,跟着近年来城镇化的推动和乡村出产、生活方式的改动,乡村沼气建造现已出现了新的改变。
As an important part of renewable energy, biogas has gone through decades of development in the vast rural areas of China. Data show that the number of biogas users in China has reached tens of millions. With the promotion of urbanization and changes in rural production and lifestyle in recent years, new changes have taken place in rural biogas construction.
和传统的户用沼气项目比较,新型沼气提纯项目在规模、技能等方面有很大优势。在质料充足的情况下,既能够出产沼气以及提纯之后的高纯度生物天然气,也能够直接利用沼气发电。
Compared with the traditional household biogas project, the new biogas purification project has great advantages in scale and skills. In the case of sufficient materials, it can not only produce biogas and purified high-purity biogas, but also directly use biogas to generate electricity.
和太阳能、风能、水能等其他可再生清洁动力比较,规模化沼气提纯项目受自然环境影响更小,在大部分乡村区域都能够建造。多年来,在推动秸秆禁烧和乡村面源污染管理方面下了很大力气,但在一些区域,乡村焚烧秸秆和畜禽粪便污染问题仍时有发生。究其原因,便是没有很好的处理方式。而沼气项目的质料主要便是秸秆和畜禽粪便,这关于秸秆禁烧、改进大气环境以及削减乡村面源污染都有促进作用。这一优势,是其他清洁动力无法比较的。沼气提纯,让沼气更有“朝气”。
Compared with solar energy, wind energy, water energy and other renewable clean power, large-scale biogas purification projects are less affected by the natural environment and can be built in most rural areas. Over the years, great efforts have been made to promote the prohibition of straw burning and the management of rural non-point source pollution, but in some areas, the pollution problems of straw burning and livestock manure still occur from time to time. The reason is that there is no good way to deal with it. The main materials of biogas project are straw and livestock manure, which can promote the prohibition of straw burning, improvement of atmospheric environment and reduction of rural non-point source pollution. This advantage can not be compared with other cleaning power. Biogas purification makes biogas more vigorous.
