Description

Novel high density anaerobic waste water fermentation unit
Technical field
The utility model relates to the fermentation unit in the field of waste water treatment, especially a kind of novel high density anaerobic waste water fermentation unit.
Background technology
In the production process of much brewageing with the bio-pharmaceuticals industry, all can produce a large amount of high concentrated organic wastewaters; Like industries such as alcohol, drinks, Hydrocerol A, monosodium glutamate, starch and sauce vinegar; These high concentrated organic wastewaters are not if effectively utilize; Directly adopt routine biochemistry treatment process qualified discharge, need to consume a large amount of energy and process cost.In order to address the above problem; At present high-concentration waste water is adopted resource treatment technique usually earlier; Promptly adopting fermentation reactor that waste water is carried out anaerobically fermenting handles; The methane gas that the production added value is very high reduces the concentration of COD and BOD in the high-concentration waste water simultaneously, alleviates follow-up biochemical qualified discharge load of processing.
Existing fermentation reactor mainly is made up of housing, water-in, water outlet and near be installed in the liquid level of reactor drum top triphase separator, fills the anaerobic grain sludge bed in the housing of reactor drum.Behind the water-in entering reactor drum of waste water by reactor bottom, under the effect of anaerobion, react, can generate methane gas, the methane gas that is produced is gathered into the bubbles of different sizes in reactor drum, rise to reactor drum top gradually and discharge.Because methane gas is in uphill process; Can and carry secretly the generation disturbance of the anaerobic sludge in the reactor drum, therefore when the methane gas of high concentrated organic wastewater generation was too much, methane gas cognition formed bigger bubble; Even form zooming air-flow; The mud that this zooming bubble is carried secretly can make the triphase separator separation efficiency on reactor drum top descend, and mud granule is difficult to be deposited on the Sludge Bed, causes the loss of anaerobion; Influence the concentration of anaerobion in the reactor drum, finally cause the anaerobically fermenting water treatment effect poor.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of simple in structure, reasonable in design, can avoid a large amount of methane gass to assemble, reduce and carry the mud granule phenomenon secretly, improve reaction efficiency and alleviate the novel high density anaerobic waste water fermentation unit of triphase separator WP.
The utility model solves its technical problem and realizes through following technical scheme:
A kind of novel high density anaerobic waste water fermentation unit; Comprise a reactor drum that mainly constitutes by housing and triphase separator; Triphase separator is installed in the upper end of enclosure interior, and lower housing portion is provided with water-in, and housing top sets out the mouth of a river; It is characterized in that: comprise that also is arranged on the outside bypass gas riser tube of reactor drum, this bypass gas riser tube is connected with the enclosure interior of reactor drum.
And, put the anaerobic sludge that contains anaerobion in the described reactor shell, this anaerobic sludge forms the granule sludge layer in the intravital bottom of shell, forms the floc sludge layer at the intravital middle part of shell.
And the staggered installation of the inner wall even distribution of said reactor shell middle and lower part is tilted to down the oblique cutting plate that is provided with for one group.
And, filling liq water in the described bypass gas riser tube, the top of bypass gas riser tube is shaped on pneumatic outlet.
And described bypass gas riser tube is communicated with through a plurality of drainage tubes with reactor shell.
And the collection chamber of said reactor drum triphase separator is connected with the bypass gas riser tube through last drainage tube, and the tie point of bypass gas riser tube one end is positioned at the top of bypass gas riser tube liquid level.
And a horizontal drainage tube that is connected with the bypass gas riser tube is all installed in the below of said each oblique cutting plate.
And the bottom of said reactor drum is connected with the bottom of bypass gas riser tube through following drainage tube.
Advantage of the utility model and beneficial effect are:
1, the reactor shell in this reaction unit is communicated with a bypass gas riser tube; In reaction process, utilize the principle of equal height with pressure, a large amount of methane gass that produce in the reactor drum can be got in the bypass gas riser tube in segmentation; Reduce the gas vol in the reactor drum; Slow down the riser speed of methane gas in the reactor drum, help the sedimentation of top mud granule, and do not influence the fermenting process of inside reactor.
2, a plurality of oblique cutting plates that are provided with that are tilted to have down been installed in the middle and lower part of reactor wall; And a horizontal drainage tube is all installed in the below of each oblique cutting plate; This zone is the quick gas-producing area of methane; The oblique cutting plate has played the effect that stops that methane gas rises continuously, and the methane blended gas segmentation of quick generation is separated, and gas is temporarily concentrated on oblique cutting plate below; And draw by horizontal drainage tube, therefore reduce air-flow and gathered the too fierce turbulence of generation and the phenomenon of carrying mud granule secretly in a large number.
3, owing to can prevent that granule sludge from flowing out after using this device; Especially reduced carrying secretly and impact to the top floc sludge; Therefore help keeping mud in the housing layered arrangement, keep the intravital mud granule concentration of shell, thereby guaranteed the carrying out smoothly of fermentation reaction, improved reaction efficiency, improved reaction effect, alleviated the load of triphase separator.
4, this device also helps the further generation of methane gas owing to can in time draw methane blended gas, promotes methanation.
5, this apparatus processes ability is big, can greatly reduce wastewater treatment space and working cost, reduce the enterprise production cost.
6, the utility model is a kind of design science, simple in structure, easy to use and practical novel high density anaerobic waste water fermentation unit; Because the bottom of bypass gas riser tube is connected with reactor drum; The pressure drop of whole riser tube and reactor drum keep balance, and liquid does not flow, and only plays the effect of a fluid-tight; The gas at oblique cutting plate place all can get into the bypass gas riser tube naturally; The gas that can significantly reduce inside reactor gathers in a large number, and the stable particle layer promotes aerogenesis; Solved well that granule sludge is gathered the back fast rise by gas and the problem of carrying secretly, reduced the top triphase separator load, improved fermentation efficiency, avoided a large amount of losses of mud.
