Description
Technical field
The utility model belongs to Anaerobic wastewater treatment equipment, relates to a kind of novel anaerobic baffled reactor.
Background technology
The anaerobic biological treatment of waste water refers under the condition without the need to providing external source energy, using organism as hydrogen acceptor, the organism of the various complexity in waste water is changed into the compound of simple and stable under the effect of microorganism, and produce the energy-biogas having utility value simultaneously.Along with the development of anaerobic technology, wherein upflow anaerobic sludge blanket reactor (Up-flowAnaerobicSludgeBlanketReactor, be called for short UASB) be most effective at present, most widely used a kind of anaerobic biological treatment reactor, but because upflow anaerobic sludge blanket reactor is by the restriction of suspended substance, once water inlet in suspension content more than 4000mg/L, whole treatment process just can not normally run, therefore a kind of anaerobic reactor (ABR of new high-efficiency is proposed the people such as McCarty of early 1980s U.S. Stanford university, AnaerobicBaffledReactor).
The built-in some vertical flow deflectors of ABR reactor, the waste water be processed is entered after reactor along current downflow on traverse baffle, each Sludge Bed successively in reactor, the gas produced by means of process waste water and the flowing of sewage, perturbation action is played to Sludge Bed, due to the settlement performance of mud and the barrier effect of traverse baffle, most of anaerobic sludge can be made to be trapped in reactor within.ABR reactor has the following advantages: 1, waste water is complete mixed state in each independent compartment, plug-flow state is presented in whole reactor, the compound fluidised form that this plug-flow combines with complete mixed flow is extremely conducive to the capacity utilization ensureing reactor, the stability that accelerating system runs.
2, in ABR reactor, flow deflector is set, reactor is divided into much independent reaction chamber, these reaction chamber series operations, each reaction chamber can regard an independent upflow sludge blanket as, these relatively independent compartments, can realize microbial population and grow under the environment be applicable to separately, achieve being separated of acid-producing bacteria and methanogen, thus improve anaerobism removal efficiency, be conducive to the stability ensureing anaerobic system.
At present in anaerobic baffled reaction device, a kind of baffled reactor first compartment that Chinese patent CN201704128U announces is identical with the volume of follow-up several compartment, in actual moving process, load suffered by first compartment is far above the mean load suffered by system, the first compartment is easily caused to go out the phenomenon of water-band mud, the stability of influential system.A kind of novel baffled reactor that Chinese patent CN201433133Y announces mainly replaces deflected current wall with thrust-augmenting nozzle, the problem that the difficulty of construction that solution apart too closely causes due to division plate and flow deflector is larger, but this device easily forms dead band in actual moving process near division plate, decrease the useful volume of reactor, affect the removal efficiency of reactor.
Summary of the invention
The purpose of this utility model is to provide a kind of novel anaerobic baffled reactor, solution baffled reactor easy sludge loading of the first compartment in operational process too high causing runs mud, easily occurs the problem of dead band and anaerobic baffled reactor final outflow water band mud below division plate.
The technical scheme that the utility model adopts is: a kind of novel anaerobic baffled reactor, reactor is encloses container, by dividing plate, reactor is divided into different compartments, each compartment comprises a upstream room and downstream room, from the first compartment bottom water inlet, from last upper compartment water outlet, this reactor comprise distribution reservoir, cutoff board, traverse baffle, collection and confinement of gases mouth, distribution reservoir, flow-stopping plate 1. number, flow-stopping plate 2. number, recycle pump, water distributor, swash plate.It is characterized in that the volume of the first compartment is 2-3 times of all the other compartment volumes, and be furnished with recycle pump, distribution reservoir and water distributor.The flow of recycle pump is 2-3 times of flooding velocity, the phenomenon that the first compartment caused because sludge loading is too high runs mud can be alleviated like this, external recycle pump and 5-10 root water distributor is set can solves problem due to larger the brought water distribution inequality of the first compartment volumes, and the lower end of traverse baffle is positioned at the 1/2-2/3 place of upstream room, with the angle of horizontal plane at 30 ° ~ 50 °, flow-stopping plate 1. number with the angle of horizontal plane at 30 ° ~ 50 °, flow-stopping plate 2. number with the angle of horizontal plane at 50 ° ~ 80 °, dead zone area can be reduced like this, increase the useful volume of reactor.Last compartment is by the control to swash plate angle, surface load can be reduced, for floc sludge, the angle of swash plate and horizontal plane controls at 10 ° ~ 50 °, for granule sludge, the angle of swash plate and horizontal plane controls at 40 ° ~ 90 °, can prevent the race mud phenomenon because the water yield causes too greatly, be conducive to the stability of system, improve the anaerobism effect of baffled reactor.
