Description
Technical field
The present invention relates to utilization and the organic waste biologic treating technique of organic waste class renewable energy source.
Background technology
The burning of conventional fossil fuel can produce a large amount of greenhouse gases and SO
2the pollutents such as flue dust, simultaneously along with the development of human society comprises the Nonrenewable energy resources worsening shortages of coal, oil, Sweet natural gas, the exploitation of novel renewable energy worldwide cause concern.
Due to society and industrial expansion, excessive nitrogen phosphorus is discharged among water body, and body eutrophication becomes normality, causes poisons in freshwater explosive blue-green alga bloom.The topmost counter-measure of current China's reply blue algae bloom is collection, salvages blue-green algae, and the blue-green algae after salvaging is not if being further processed, and not only can take tract to stack, and the blue-green algae of simultaneously piling up for a long time can cause secondary pollution again to the environment of periphery.Maize straw is stem, leaf part after corn maturation, and current Rural areas also exists the phenomenon of many crop straw burnings, and often causes a series of environmental problem thus.Analytical study shows all containing abundant carbohydrate and protein in blue-green algae and maize straw, therefore can as biomass energy in order to produce ethanol, biogas etc.
Biogas be organism under anaerobic through fermentable effect generate a kind of mixed gas, belong to renewable energy source, its main component is CH
4and CO
2, research shows 1m
3cH
4the biogas that content accounts for 65% is equivalent to 0.6m
3sweet natural gas, l.375m
3town gas, the raw coal of 0.76kg and the electricity of 6.4kwh.So the utilization and extention of biogas has good economic benefit, organism changing waste into resources is converted into biogas then also with ecological benefits and environmental benefit simultaneously.
Burn and energy deficiency for solving straw from village, China just widelys popularize Gas application in rural area as far back as the initial stage seventies, such as, but still there are some problems for anaerobic fermentation of organisms at present, the fermentation starting time is long, the slow and methane output capacity of fermentation rate is lower.Anaerobic fermentation process affects by substrate component, temperature of reaction, pH, nutritive element and trace element, how optimization of fermentation conditions, improves fermentation efficiency and has become in biogas career development process the major issue needing solution badly.
Propose for the domestic and international experts and scholars of the problems referred to above the method that some improve methane phase efficiency, such as, by mixed fermentation balance substrate C/N, the biodegradability that pre-treatment improves substrate is carried out to substrate, adds trace element and improve microorganism active etc.
Patent publication No. is that blue-green algae mixes with feces of livestock and poultry and carries out wet fermentation by the patent of invention of 104120151A, then uses reed and rice straw and wet fermentation biogas residue mixed fermentation, achieves the comprehensive utilization of agricultural waste.Patent publication No. is that the patent of invention of 102140001A is passed through to add ferriferous oxide in anaerobic reaction system, improves the reproducible utilization efficiency of organic waste.Patent publication No. be the patent of invention of 103773807A using short chain fatty acid as electron donor, using nano magnetite as electron carrier, facilitate the degraded of short chain fatty acid, improve the operational efficiency of methane-producing reactor.It is expensive and improve the defect of the technical difficulty of natural pond Slag treatment to there is complex steps, complicated operation or additive in aforesaid method.
