Description
Technical field
The invention belongs to renewable energy source development and use and field of environment protection, be specifically related to the anaerobic ferment process of a kind of combined treatment of dejection and stalk.
Background technology
The waste of agriculture production and life in the countryside discharging has become one of primary pollution source that causes China's body eutrophication.The data that " the TAIHU LAKE prevention and cure of pollution Tenth Five-year plan " provides show that agricultural pollution surpasses 50% to the contribution rate of Taihu Lake basin principal pollutant ammonia nitrogen; According to the data in " Dianchi Lake Basin widespread pollution from the overuse of fertilizers and pesticides in rural area control special investigations report ", Dianchi Lake Basin has 320,000 tons of solid waste to flow into the Dian Chi every year, and wherein people's domestic animals manure is 240,000 tons.These wastes contain 426.6 tons of total phosphorus, 1167 tons of total nitrogens.For another example, main now the vast rural area of the pollution of Hangzhou Wan from the Yangtze valley.In total pollution, the proportion that agricultural pollution source accounts for is very big, is example with the inorganic nitrogen, and feces of livestock and poultry accounts for 35%.
At present, in many agriculturals that cause water pollution and rural area source of pollution, culture ight soil and agricultural run-off contribution rate maximum, become the important factor that the puzzlement water surrounding is improved the water pollution load.Improvement to these two classes source of pollution has become the important topic that improves quality of water environment.But present many control measures are not owing to have and will pollute relevant agricultural with water and rural problem is on the whole treated as one, and bias toward improvement more, have ignored recycling, make that some treatment facilities are for want of economical to support and have to out of service.
Agricultural and development of countryside be unable to do without " three material ", i.e. fuel, fertilizer and feed.And this " three material " exists direct or indirect relation with water pollution problems, agricultural run-off pollutes and comes down to fertilizer pollution, and improving constantly along with the life in the countryside level, fuel utilizes mode that big change is also taking place thereupon, be that main to change commercial energy resources such as using coal, liquefied gas into be main promptly by biomass such as original burning straws, the feed function of stalk desalination in addition, thereby discarded and waste burning that causes stalk.The random stacking of stalk on field and irrigation canals and ditches and other places certainly will cause a large amount of losses of N, P.If by rational technological approaches these wastes are carried out the resource utilization development and use, in " three material " problem of solution, water pollution problems also can obtain basic solution.
At first, with regard to the feces of livestock and poultry that aquaculture produces, annual more than the 2500000000 ton of feces of livestock and poultry contained energy that produces of China approximately can be converted into 300,000,000 tons of mark coals.Secondly, the year output of China's agricultural crop straw is about 700,000,000 tons, is equivalent to 3.5 hundred million tons of mark coals.And China's coal consumption total amount in 2005 is 2,100,000,000 tons of raw coal.Therefore, they are carried out trans-utilization on the spot in the rural area, when solving the water pollution problems that causes by them, can also produce the fine clean energy.As the mode by the anaerobe fermentation stalk and feces of livestock and poultry are converted into biogas, not only can solve the needs of problems of rural area to the high-grade energy product, the by product that fermentation produces also can be used as fertilizer and is used.That is to say the recycle that has realized material by such mode, will solve by its discharging or the discarded water pollution problems that causes thereupon, thereby play the effect that when the water comes, a channel is formed.
Ight soil and stalk all are biomass resources, it is carried out the energy development and use meet the strategic demand that present China greatly develops bioenergy.The valuable source of human future development as an influence, the development and use of biomass energy are in many countries, and especially state such as America and Europe is subjected to unprecedented attention.
The U.S. has proposed the year two thousand twenty makes bioenergy reach 25% of its energy aggregate consumption, annual reduces 100,000,000 tons of carbon emission amounts and 20,000,000,000 dollars the grand target of increasing farmers' income.European Union also is to pay much attention to the development of renewable energy source, issued " European Union's strategy and action white paper " in 1997, propose 2010, the consumption of renewable energy sources in EU will by 1997 about 6% bring up to 12%, the utilization of bioenergy will reach 200,000,000 tons of mark coals.The bulletin of the France Ministry of Agriculture shows that by 2010, France can realize that renewable energy source consumption increases by 50%, and the electric power of production of renewable energy resources reaches 21%.United Kingdom Government just expands a fighting force, and increases investment, the development and utilization of the stimulating organism energy, the target that is provided by renewable energy source with the energy consumption that is implemented to 2010 10%.
Along with Chinese national economy development continuously and healthily, some energy consumption industries present the fast-developing impetus, make that energy aggregate demand obviously increases, price constantly rises, and the situation of power supply anxiety is continuing to increase in the frequency that some developed areas occur.The development of pushing forward renewable energy sources such as biomass energy comprehensively has been subjected to national great attention as an important behave alleviating China's energy availability and demand contradiction." the medium-term and long-term development program of renewable energy source " according to National Development and Reform Committee in 2006 issue will account for 10% of total energy consumption to China's renewable energy source in 2010, biogas year utilization to reach 19,000,000,000 m
3To account for 16% of total energy consumption to the year two thousand twenty China renewable energy source, biogas year utilization to reach 44,300,000,000 m
3" planning " proposes simultaneously will be with the development and use of the countryside biomass energy source important measures as developing modern agriculture, building a New Socialist Countryside.
Under the support of national policy, the household biogas technology has obtained fast development in China, but with regard to present development, a main problem of existence be the raw material that uses too single, promptly mainly adopting feces of livestock and poultry is fermentation raw material.Stalk raw materials is considered to be not suitable for use in the fermentation raw material of domestic methane tank owing to problems such as having raw material layering, crust and discharging difficulty in anaerobic fermentation process.And in China relatively advanced Rural areas of many economy, because traditional aquaculture model, be that the mode that single household raises livestock scattered is eliminated substantially, this has limited this technology to a great extent in these geographic application, on the other hand, because the continuous increase to the clean fuel demand makes the pressure of these regional commercial energy resource supplies also be continuous increase trend, and the constantly soaring peasant's burden in this respect that also increased the weight of of commercial energy resource price.Meanwhile, these areas are annual all to have a large amount of stalk resources to be discarded in vain, has not only polluted environment, has also caused the very big wasting of resources.
