The utility model comprises four sludge intakes, four downlink flow chambers, four baffle plates, four uplink flow chambers, a sludge discharge outlet, four sludge discharge pipes( empty discharging pipes), four air-outlet channels, four sludge stirring pumps and an inner cylinder. The inner cylinder and the four baffle plates are made of the materials having good heat conduction effect. The utility model has the advantages of simple design, low investment and operation cost, and needs not to take the sludge precipitation and gas-liquid separation measures and needs to specially separate the gas from the liquid; the utility model can operate intermittently with low HRT, can not generate a plurality of sludge in long-term operation, can take the function of two phase anaerobic digestion system; and the bacteria rises and decreases slowly in the reactor; the device is less heat loss and high heat transferring efficiency.
Description
Technical field the utility model belongs to sewage sludge treatment technology and field of environment protection, is specifically related to a kind of sewage sludge anaerobic processing device.
The sewage sludge of background technology municipal sewage plant is the by product that the sewage treatment process system produces.Along with improving constantly of the increasing and wastewater treatment rate of the generation of municipal effluent, consequent sewage sludge output is more and more.Sewage sludge is a kind of water ratio height, contain the semi-drying solid waste of large amount of organic and hazardous and noxious substances (comprising microorganism, heavy metal and toxic organic compound etc.), big, easy corrupt, unstable, the foul smelling of its capacity, as not safe handling and disposal in addition, serious secondary pollution problem will be caused.
People just begin to adopt the anaerobic technique sewage sludge before more than 100 years.Between 1910～nineteen fifty, efficiently, can add the gentle sludge digestion tank that stirs and obtained further development, as the anaerobism contact process, these reactors are called as first-generation anaerobic reactor.Because first-generation anaerobic reactor can't separate sludge retention time and hydraulic detention time, the residence time in mud mesophilic digestion pond reaches 20～30d, and volume and floor space that this has just increased digester have greatly improved construction cost.
In order to improve the processing efficiency of anaerobic reaction system, people have have successfully researched and developed s-generation anaerobic reactor, for example anaerobic filter (AF), up flow anaerobic sludge blanket reactor (UASB), anaerobic fluidized bed (AFB) and anaerobism contact membranes expanded bed reactor (AAFEB) etc.Their common characteristic can be separated solid retention time and hydraulic detention time exactly, and this makes the interior solid retention time of reactor can reach up to a hundred days, and hydraulic detention time can shorten to several days from tens days of past, even several hours.In these efficient anaerobic treatment systems of having developed, UASB extensively is used in the actual production.
Though s-generation anaerobic treatment process is obtained very ten-strike in application, but when further enlarging its range of application, still run into many problems, forced people to proceed research and development on this basis, developed the third generation and novel anaerobic reactor so in succession.Mainly comprise expanded granular sludge bed (EGSB), anaerobism inner circulation reactor (IC), anaerobic baffled reactor (ABR) etc.
But also there is the shortcoming of self in above-mentioned reactor.As baffled reactor, one-sided water inlet has caused the uneven distribution of matrix, and then to cause the inhomogeneous of microbial profile, net result be that reactor efficiency is not high.Simultaneously, when being used for sludge high temperature or mesophilic digestion, thermo-efficiency is lower.The art of this patent can address these problems well.
Summary of the invention the utility model provides a kind of subregion to advance mud circulation deflector type sewage sludge anaerobic processing device, to solve the problems such as matrix skewness that present anaerobic reactor exists.
Subregion of the present utility model advances mud circulation deflector type sewage sludge anaerobic processing device by mud inlet 1, mud inlet 5, mud inlet 9, mud inlet 13, downstream chamber 2, downstream chamber 6, downstream chamber 10, downstream chamber 14, traverse baffle 3, traverse baffle 7, traverse baffle 11, traverse baffle 15, up stream chamber 4, up stream chamber 8, up stream chamber 12, up stream chamber 16, mud discharging mouth 17, shore pipe (blow-down pipe) 22, shore pipe (blow-down pipe) 23, exhaust-duct 24, exhaust-duct 25, exhaust-duct 26, exhaust-duct 27 and inner cylinder 28 are formed.In order to improve heat transfer efficiency, inner cylinder 28, traverse baffle 3, traverse baffle 7, traverse baffle 11, traverse baffle 15 are made by the material of good heat conduction effect.For mud evenly being suspended in device and improving mass-transfer efficiency and establish mud in bottom, four up stream chambers and stir that pump 18, mud stir pump 19, mud stirs pump 20, mud stirring pump 21.
Advantage of the present utility model is:
1. simplicity of design, no moving-member, it is few just to build cost, and high gap volume reduces and stops up, and investment and working cost are low.
2. need not add the sludge settling measure, sludge yield is low, and the SRT height need not special gas-liquid separation.
When operation low HRT, can intermittent operation, anti-hydraulic load and organic loading surging force are strong, anti-Toxic ability is strong, the long-time running sludge yield is low.
4. separate acid-producing bacteria and methanogen along the reactor flow process, play biphasic system, but do not have a biphasic system jointly control problem and high cost.Because the acidifying bacterium accumulates in the front compartment, two-phase operation can improve acidifying bacterium and methanogen activity, and different bacterial classifications can be survived in different control environments.
5. because the flowing and the generation of gas of water, the slow lifting of bacterium in the reactor, but under less liquid speed, be sunken to lower curtate.
6. employing center and compartment blade heating, temperature or hot environment in the formation reduce thermosteresis, and the outer surface area of unit volume are little.
Appended drawings is the utility model structural representation.
The embodiment sewage sludge enters downstream chamber 2, downstream chamber 6, downstream chamber 10, downstream chamber 14 respectively through mud inlet 1, mud inlet 5, mud inlet 9, mud inlet 13 respectively in proportion.Sewage sludge enters up stream chamber 4 by downstream chamber 2 through traverse baffle 3, the 4 top bafflings in the up stream chamber, and it is descending to enter downstream chamber 6, enters up stream chamber 8 through traverse baffle 7 again.The 8 top bafflings in the up stream chamber, it is descending to enter downstream chamber 10, enters up stream chamber 12 through traverse baffle 11 again.The 12 top bafflings in the up stream chamber, it is descending to enter downstream chamber 14, enters up stream chamber 16 through traverse baffle 15 again, discharges by mud discharging mouth 17 at last.The effect that mud in bottom, four up stream chambers stirs pump 18, mud stirring pump 19, mud stirring pump 20 and mud stirring pump 21 is to make mud be in suspended state to prevent the blocking device passage, also plays the effect that improves mass-transfer efficiency simultaneously.Shore pipe (blow-down pipe) 22 and the shore pipe (blow-down pipe) 23 of regularly opening the bottom carry out spoil disposal.Open shore pipe (blow-down pipe) 22 and shore pipe (blow-down pipe) the 23 emptying sewage sludges of bottom when washing unit is inner.The effect of the exhaust-duct 24 of reactor head, exhaust-duct 25, exhaust-duct 26, exhaust-duct 27 is the gas that produces in the sewage sludge process in the discharger.Outside heat heats by inner cylinder 28, traverse baffle 3, traverse baffle 7, traverse baffle 11,15 pairs of sewage sludges of traverse baffle.
