我們常??梢钥吹?,在沼澤地里或者污水池里經(jīng)常會有氣體產(chǎn)生,如果這時劃著火柴,可把它點著,這就是自然界天然發(fā)生的沼氣。從科學(xué)界說角度看,沼氣是各種有機物質(zhì),在阻隔空氣(還原條件),并在適合的溫度、PH值下,經(jīng)過微生物的發(fā)酵效果發(fā)生的一種可焚燒氣體。沼氣歸于二次能源,并且是可再生能源。沼氣提純變廢為寶,完成多業(yè)態(tài)循環(huán)工業(yè)發(fā)展新格局。
We can often see that gas is often produced in swamps or sewage pools. If a match is struck at this time, it can be lit. This is the natural biogas in nature. From a scientific point of view, biogas is an incinerable gas produced by various organic substances through microbial fermentation at suitable temperature and pH value under the condition of blocking air (reduction conditions). Biogas belongs to secondary energy, and is renewable energy. Biogas purification turns waste into treasure, and completes a new pattern of multi format circular industry development.
沼氣提純是有機物質(zhì)在厭氧條件下,經(jīng)過微生物的發(fā)酵效果而生成的一種混合氣體。人畜糞便、秸稈、污水等各種有機物在密閉的沼氣池內(nèi),在厭氧(沒有氧氣)條件下發(fā)酵,被品種繁復(fù)的沼氣發(fā)酵微生物分化轉(zhuǎn)化,然后發(fā)生沼氣。
Biogas purification is a kind of mixed gas produced by the fermentation effect of microorganism under anaerobic conditions. Human and animal feces, straw, sewage and other organic substances are fermented in a closed biogas digester under anaerobic (no oxygen) conditions, and are differentiated and transformed by a variety of complex biogas fermentation microorganisms, and then biogas is produced.
沼氣是多種氣體的混合物,其特性與天然氣相似。沼氣除直接焚燒用于炊事、烘干農(nóng)副產(chǎn)品、供暖、照明和氣焊等外,還可作內(nèi)燃機的燃料以及生產(chǎn)甲醇、福爾馬林、四氯化碳等化工原料。經(jīng)沼氣提純設(shè)備發(fā)酵后排出的料液和沉渣,含有較豐富的營養(yǎng)物質(zhì),可用作肥料和飼料。
Biogas is a mixture of many gases, and its characteristics are similar to natural gas. In addition to being directly burned for cooking, drying agricultural and sideline products, heating, lighting and gas welding, biogas can also be used as fuel for internal combustion engines and to produce chemical raw materials such as methanol, formalin and carbon tetrachloride. The material liquid and sediment discharged after fermentation by biogas purification equipment are rich in nutrients and can be used as fertilizer and feed.
為了節(jié)約建設(shè)成本可以建造城市小區(qū)居民衛(wèi)生間下水道發(fā)生糞便的沼氣處理站,一方面制造成鋼瓶方式,另一方面建造沼氣輸送管道。在周圍建造綠色農(nóng)業(yè)發(fā)生基地,發(fā)生沼液能夠做成無土栽培農(nóng)業(yè)栽培質(zhì)料,沼渣直接加工成有機化肥。
In order to save the construction cost, we can build a biogas treatment station for the feces in the toilet sewers of urban residential quarters. On the one hand, it can be made into a steel cylinder, on the other hand, it can build a biogas pipeline. The biogas slurry can be made into soilless cultivation materials, and the biogas residue can be directly processed into organic fertilizer.
