沼氣作為可再生能源的重要組成部分,沼氣在我國廣大鄉村區域現已走過了數十年的發展歷程。數據顯現,目前全國沼氣用戶已達到上千萬戶,跟著近年來城鎮化的推動和鄉村出產、生活方式的改動,鄉村沼氣建造現已出現了新的改變。
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.
和傳統的戶用沼氣項目比較,新型沼氣提純項目在規模、技能等方面有很大優勢。在質料充足的情況下,既能夠出產沼氣以及提純之后的高純度生物天然氣,也能夠直接利用沼氣發電。
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.
和太陽能、風能、水能等其他可再生清潔動力比較,規?;託馓峒冺椖渴茏匀画h境影響更小,在大部分鄉村區域都能夠建造。多年來,在推動秸稈禁燒和鄉村面源污染管理方面下了很大力氣,但在一些區域,鄉村焚燒秸稈和畜禽糞便污染問題仍時有發生。究其原因,便是沒有很好的處理方式。而沼氣項目的質料主要便是秸稈和畜禽糞便,這關于秸稈禁燒、改進大氣環境以及削減鄉村面源污染都有促進作用。這一優勢,是其他清潔動力無法比較的。沼氣提純,讓沼氣更有“朝氣”。
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.
