Description
Technical field
This utility model relates to the device of a kind of fermentation process, especially discharge waste liquid, discarded biogas slurry and sanitary wastewater by the feces/flushing of livestock and poultry cultivation and straw carries out device and the application thereof of fermentation process.
Background technology
Along with livestock and poultry breeding industry develops, animal excrements quantity gets more and more, and feces of livestock and poultry has become important polluter, drastically influence ecological environment security；Feces of livestock and poultry, aquaculture wastewater harmless treatment are carried out farmland reuse is one of effective way, particularly animal waste is carried out producing methane through anaerobic fermentation, the reuse of biogas slurry and biogas residue farmland, dispose realizing breeding waste and while utilization, biomass energy can be obtained again.Thus, the coordination of farming and animal husbandry type technology with biogas engineering as tie, having obtained the whole society pays close attention to and payes attention to, and has obtained wideling popularize application.
Ending 2014, at national all kinds of biogas engineerings 100,000, biogas annual production reaches 180 billion cubic meters, nearly 600,000,000 tons/year of biogas slurry, biogas residue generation amount.In cultivation-plantation practical engineering application, owing to biogas slurry discharge has the features such as a large amount of property, seriality, routine utilizes the method for biogas slurry generally as fertilizer also field, and farmland planting water fertilizer is seasonal and quantitative；Therefore substantial amounts of biogas slurry every day can not be used for farmland in time；So that more outlet utilizes biogas slurry.
On the other hand, along with economy and the development of intensive agriculture in rural area, straw starts to become the another big garbage source in rural area.Annual " crop straw burning " problem annoyings a lot of area of China.The annual summer harvest and when the autumn and winter, always has the straws such as substantial amounts of Semen Tritici aestivi, Semen Maydis to burn in field, creates a large amount of heavy smog, not only become the bottleneck problem of rural environmental protection, even become the arch-criminal bringing disaster to urban environment.Crop straw burning, is not because straw is too many, and is because not being fully utilized.According to the relevent statistics, China, as large agricultural country, can generate more than 700,000,000 ton of straw every year, becomes " use is little " but " garbage " that must dispose.In the case, processed by peasant completely, occurred as soon as the phenomenon of a large amount of burning.Therefore, utilize straw to absorb biogas slurry, be converted into fertilizer, be a kind of effective method.
Such as: utility model patent, the dry-type anaerobic fermentation device (CN104328041A) of a kind of biogas slurry spray straw utilizing recovery.Its principle is identical with the design, but equipment form differs greatly, this utility model devise a kind of in have the anaerobic fermentation tank of spray head, discharging tube and gas outlet, built with straw, utilize biogas slurry reflux pump biogas slurry to be sprayed straw above fermentation tank.Straw and biogas slurry is utilized under anaerobic to produce biogas.This utility model is to reclaim biogas slurry by traditional anaerobic fermentation method, and advantage is that speed is fast, Automated condtrol；The restriction treating capacity that shortcoming is affected by tank body is limited, and involves great expense, and the suitability is poor, additionally, this device is the application for the purpose of producing biogas slurry, for cultivation waste liquid or sanitary sewage, the most helpless.
The most such as, for the secondary pollution preventing biogas slurry from utilizing, environment being produced, utility model patent, a kind of method (CN102775026A) utilizing modified coal ash to process biogas slurry, changing utility model utilizes modified coal ash to process biogas slurry, first biogas slurry and biogas residue is separated, then will add a certain amount of modified coal ash in biogas slurry, fully again through SBR aeration after reflection, reduce in biogas slurry pollution factor to qualified discharge.The method belongs to biogas slurry and purifies utility model, differs greatly with the ultimate principle of the design.Utility model patent, straw also field operational method and facility (CN104255202A) Tong Bu with biogas slurry, complete to crush and shed on field by crop material and root stubble in field, the biogas slurry produced after biomass anaerobic fermentation is sprayed on broken straw and root stubble, mouldboard plow is utilized to carry out the flat work of turning in soil, broken straw, root stubble are buried in the lump with biogas slurry and covers in soil, finally surface, soil, field is carried out suppression compacting leveling operation.This utility model belongs to field and utilizes, and recycles with biogas slurry and differs greatly.
The most such as, for the secondary pollution utility model patent preventing the kitchen waste water in sanitary sewage from environment being produced, a kind of straw processing method (CN104445513A) adsorbing oils and fats in kitchen waste water, crushed stalk is formed granule, add flocculant and mix thoroughly, making straw coagulated particles；Straw coagulated particles is put in kitchen waste water, makes Adsorption of Organic in sewage form attached oil particles on straw coagulated particles；Separate and collect attached oil particles, carrying out subsequent bio fermentation process.This utility model solves that high concentration kitchen waste water intractability is big, cost is high, and the problem of property balanced in nutrition difference when kitchen waste water and straw individually ferment.
Visible by above-mentioned patent, in the face of a large amount of straws, aquaculture wastewater, the sanitary sewage pollution to environment, although people take many methods and measure, not fully up to expectations, really need to research and develop a kind of can be for the comprehensive treatment device of above-mentioned polluter.
Utility model content
