Description
Technical field
The utility model relates to a kind of biogas production device, is particularly useful for the large-sized biogas producer of industry, life treatment of Organic Wastewater.
Background technology
Municipal effluent mainly is to utilize sewage work to handle, according to international way, and the severe situation that faces of China's water surrounding, it is trend of the times that sewage enters factory.But it is also very little that present China sewage advances the ratio of factory, because sewage disposal expense height is wanted round Realization sewage to enter factory and is still waiting time.
Sewage work's treatment process is a lot, and biochemical treatment process is commonplace at present.Biochemical process belongs to second-stage treatment in sewage disposal, be main purpose to remove suspended substance and the biodegradable organism of solvability, divides aerobic biochemical processing, anaerobic biological to handle.Biochemical treatment process can be divided into four big classes such as activated sludge process, biomembrance process, Biostatic pool method and soil facture.Most of a few days ago municipal sewage plants all adopt activated sludge process.
Mostly municipal wastewater treatment plant biochemical treatment process is to utilize aerobic biochemical process, in particular cases is aided with anaerobic biochemical.The aerobic biochemical facture refers under aerobic conditions, by the metabolism of aerobic bacteria, the capable machine thing in the sewage as nutrition source (food), is changed into inorganics, thereby removes the degradation water body pollution, does not generally produce biogas.The aerobe facture is equivalent to the enhanced versions of natural river natural degradation.In the aerobic biochemical facture, about 1/3 organism decomposes and biological physiology active energy is provided, and 2/3 is used for self growth, i.e. the part of activated sludge (claiming biological mud again) growth.Biological mud needs further to handle, otherwise easily becomes the secondary pollution source.Introduce the anaerobism operation, mainly contain following purpose: the one, dephosphorization, biological dephosphorization needs anaerobic environment, often increases this link before aerobic operation, does not generally collect biogas, but directly emptying, as anaerobic-aerobic (A1-O) technology.The 2nd, remove the nitrogen in the waste water, strictly say it is under anaerobic conditions, as anoxic one aerobic (A2-O) technology.Other has aerobic and anaerobism combination process such as A1-A2-O (or claiming A2/O) technology, and can will take off N and remove P and organism and handle and combine, but the cost height.The 3rd, as the pre-treatment of high-concentration waste water, because of aerobic bacteria can not be survived, aerobic method can not directly be handled high concentrated organic wastewater, as all collect biogas specially.The main technique shortcoming of sewage work is that energy consumption is big; the working cost height; the sludge treatment difficulty; the mishandling secondary pollution source that then becomes; therefore suitable treatment organic wastewater with medium-low concentration only; can not directly handle high concentrated organic wastewater, as scale animal and poultry cultivation sewage, slaughterhouse sewage, organic industrial sewage etc.
Summary of the invention
The utility model provides a kind of large-sized biogas producer that is applicable to that a large amount of industrial organic waste waters are handled, and can solve effectively that present sewage disposal energy consumption is big, working cost is high, sludge treatment is difficult, can not directly handle the problem of high concentrated organic wastewater.
To achieve these goals, the utility model comprises fermentation vat, thionizer and airway, waste and waste water are at first lost and are put into fermentation vat and carry out initial fermentation, fermentation vat is communicated to the fermentor tank top by pipeline, be extracted into big volumetrical fermentor tank by lift pump behind the certain hour and carry out Secondary Fermentation, the fermentor tank top cover adopts transparent material, the preferred glass material that adopts, sunlight can shine directly into fermentor tank and heat, the fermentation of acceleration fermented liquid, submersible pump is laid in the fermentor tank bottom simultaneously, regularly stirs fermented liquid according to pressure condition, the fermentor tank bottom is provided with sewage draining valve, can discharge from sewage draining valve through the mud after repeatedly fermenting; Fermentor tank top airway is communicated to thionizer, between fermentor tank and the thionizer air compressor is installed, and enters steam line after a large amount of biogas are desulfurized compression, directly uses for the biogas burner.
Handle industry and life organic sewage with the utility model, few characteristics of mud that have that treatment capacity is big, less energy consumption, working cost are low, produce, and can produce a large amount of biogas, not only environmental protection but also energy-conservation, have and clean easy, blowdown convenience, and the high advantage of methane gas producing efficient.
