Description

A kind of novel anaerobic reactor
Technical field
The utility model patent relates to a kind of novel anaerobic reactor.
Background technology
Anaerobic reactor of the prior art adopts following methods more:
The airtight cylindrical pond of the normal employing of common anaerobic digester, waste water directly enters in digester, through the mud of digestion, by digester bottom, is discharged, and waste water is discharged by top overflow.Muddy water mix and blend mode has three kinds: mechanical stirring in pond, and biogas stirs, and circulation Digestive system stirs.Feature is directly to process the feed liquid that suspended substance constant concentration is higher or particle is larger, but it is simple in structure, and organic loading is low, and the residence time is long, bulky, and lacks and to hold the special device that stays anaerobic sludge, can cause to run mud and cause outlet effect variation.
UASB upflow anaerobic sludge blanket reactor is comprised of reaction zone, settling region and air chamber three parts, waste water enters from reactor bottom, mix and contacted organic degraded with the anaerobic sludge of reaction zone, and produce biogas, the mixed solution of gas, water, mud rises to triphase separator, settling region in triphase separator unit completes mud-water separation, completes the separation of air water in air chamber.Its feature is that the volumetric loading of reactor is relatively high, without mixed stirring device.Shortcoming is that Flow Velocity is low, and bottom water distribution system is easily stopped up, and operation is long start time, to water quality and load, changes suddenly more responsive.
EGSB expanded granular sludge bed reactor reactor develops on UASB basis, and height and upflow velocity are higher than UASB, and are provided with a recycle pump by part effluent recycling, with the flow velocity in lift bed.Shortcoming is there is no independent degas module, and along with the rising of height, the kinetic energy of methane accumulation is more and more higher, causes the kinetic energy of exhalant region the highest, causes anaerobic sludge to be easily with gas floating.
IC inner circulation reactor is not the stack of simple two UASB reactors.Waste water is used efficient water distribution system to pump into reactor by reactor bottom, is blended in the main treatment zone of reactor lower part with the anaerobic grain sludge in reactor, and most organic matter is converted into methane and carbon dioxide.Biogas is collected by the triphase separator of bottom." air lift " producing drives current by upcast, to enter the gas-liquid separator of reactor head.Biogas overflows reactor from this separator, and current are got back to the bottom of reactor through downtake.In the precision processing district on top, waste water is further processed.Biogas spins off in the liquid phase in precision processing stage, then by the triphase separator on top, is collected, and treated water is discharged from reactor head.Its shortcoming is to adopt anaerobic grain sludge to start, and sludge seeding expense is expensive, and the waste water high for calcium contents, specific conductivity is high, solid content is large is not suitable for adopting.
Utility model content
The utility model patent discloses a kind of novel anaerobic reactor, it is in conjunction with the advantage of EGSB and IC anaerobic reactor, applied range, can adopt anaerobic grain sludge or floc sludge operation, degassed precipitation module based on particular design, this precipitation module can be by gas in the situation that of current turbulence, and water is separated with mud, hydraulic system guarantees that muddy water fully mixes, thereby guarantees efficient.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
A novel anaerobic reactor, is characterized in that, comprises, and an efficient water distribution system, waste water enters anaerobic reactor from bottom by water distribution system, evenly mixes with the anaerobic grain sludge in anaerobic reactor.Upwards, by mud bed and anaerobic bacterium generation biological respinse, organic matter degradation is produced to methane and carbonic acid gas, after degassed module is removed biogas, precipitation module solid-liquid separation, flow to outlet pipeline water outlet.The biogas that anaerobic treatment produces enters marsh gas treating system through the biogas mouth of pipe, the methane pipeline of reactor head.In order to reach sufficient mixed effect and anti-load impact, be provided with recycle pump, part waste water is back to water into the female pipe of water, after evenly mixing with former water through recycle pump from reactor top circulating line, by water distribution system, evenly enter reactor again, to regulate the upflow velocity of reactor.
A novel anaerobic reactor, is characterized in that, comprising: an anaerobic reactor, and described anaerobic reactor bottom is provided with a water distribution system, in order to distribute water; In described anaerobic reactor, being provided with successively from top to bottom a solid-liquid separation module, a degassed module, a collecting methane system, outer setting has water circulation system, utilizes recycle pump that treated water is returned to anaerobic reactor again.
Anaerobic reactor as above, is characterized in that, described solid-liquid separation module, degassed module are made by PP material.
Anaerobic reactor as above, is characterized in that, the described recycle system is utilized the external circulation line of recycle pump, and treated water is returned to anaerobic reactor again.
In sum, owing to having adopted technique scheme, the utility model anaerobic reactor applied range, the degassed settling system of relatively low volumetric loading and optimization, guarantees that stable and anaerobic sludge increases; Inner nothing running loses, without maintenance; Start time is short, and operation is controlled simple; Can meet the stricter requirement to smell, sludge yield and clean level.
