It should be noted that in order to prevent current from directly impacting bell jar, making bell jar surrounding water level more stable, described pulse cloth
Hydrophone is additionally provided with baffle plate, and described baffle plate setting is at the water outlet of described water inlet pipe.
Need it is further noted that being additionally provided with blast pipe 3 in described intake chamber 2, one end of described blast pipe 3 with described
Overboard well 9 connects, and the other end stretches out in described intake chamber 2 and is in communication with the outside.
Embodiment
Waste water enters intake chamber from water inlet pipe, installs baffle plate in water inlet pipe exit, to prevent water stream from directly impacting bell jar,
Make bell jar surrounding water level more stable.Indoor water level is gradually increasing, and in bell jar, air is escaped by gas outlet.When water level exceedes central authorities
During the pipe top of pipe (high water level in Fig. 1), in partial raw water flooding process, the air in bell jar is gradually taken away, form rainbow
Inhale.At this moment, indoor water of intaking runs through bell jar, mesotube enters overboard well to depositing reservoir water distribution system.It is brought into overboard
The air of well leans on blast pipe to discharge.When the middle water level decreasing that enters to enter the room is to the siphon destructive mouth of pipe (i.e. low water level in Fig. 1), because of sky
Gas enters bell jar and makes siphon destructive, enters the water level entered the room and rises again again.So circulate endlessly.
1st, pulse water distributing device and granule sludge
The utility model is to be taken away the air in main pipeline using the current of flowing quick in siphon pipe, makes in main pipeline
Form certain vacuum, the water in pond in the presence of atmospheric pressure inside and outside pipeline enters in pond after entering main pipeline.Due to water
Flow velocity degree is fast, and cloth water energy completes at short notice, reaches the effect of pulse, stirs the mud of the high concentration of at the bottom of pond, makes mud in pond
Water is in the state of being sufficiently mixed, and solves the short flow phenomenon in system, and anaerobic bacteria is sufficiently connect with the organic matter in waste water
Touch.
The utility model solves the muddy water mixed problem in anaerobic device very well.And save the stirring under water of costliness
System and solve the problems, such as sludge loss.Provide applicable water distribution means for anaerobic device.
The utility model pulse in averagely every 2～3 minutes once, is impacted when each pulse persistance 15～20 seconds, therefore pulse
Speed is very big, up to 3m/s, forms huge turbulation, bottom mud is taken to the top of reactor.After pulse, particle
Sludge density is big, and the momentum losing rising quickly starts to settle, and forms obvious layering.According to the observation to existing engineering,
Three layers can be roughly divided in pond：Lower floor (from the bottom of pond high about 1/3 to whole pond at) sludge concentration is high, up to 10～20g/L.Middle
Layer (at pond high about 1/3～2/3) sludge concentration be general, is 1～10g/L.It is then separating layer more upwards, only minimal amount of
Suspended sludge (predominantly active low granule sludge fragment).In anaerobic reactor startup stage, it is seeded in anaerobic reactor
Common floc sludge, continuous rising-decline process is formed by percussion of the present utility model, mud is constantly mutually collided
Hit, rub, easily form the granular sledge of compact texture.
2nd, volumetric loading rate is moderate, pollutants removal rate is high
In anaerobic reactor, accumulation has highly active anaerobic sludge to be in a large number the master that this equipment has huge disposal ability
Want reason. according to practical situations, the COD volumetric loading rate of anaerobic reactor is in 2～5kg/m3.d in the range of, average out to
3kg/m3.d., generally between 40%～55%, papermaking class waste water is often higher for soluble COD clearance.
Applying anaerobic technique of the present utility model is not simple removal pollutant, also improves wastewater biodegradability
Effect.Macromolecule organic because molecular weight huge it is impossible to through microorganism cell membrane, therefore directly can not possibly inhale for bacterium
Receive and utilize.And macromolecules degradation is small molecule by anaerobic reactor, can significantly improve the B/C ratio of waste water.
3rd, water quality wide adaptability
Apply anaerobic reactor of the present utility model does not have strict requirements to flow condition, therefore can accomplish to adapt to respectively
Plant waste water.Water inlet condition be：Temperature is 25～38 DEG C；COD and pH then has a relatively large allowed band.
4th, simple and convenient operation and maintenance
Apply anaerobic system of the present utility model no running device, the no three phase separator of complexity, segment pulse is complete
Automatic operation, can accomplish unmanned.
5th, delay fouling, increase the service life
In biological wastewater treatment, calcium carbonate, the fouling of magnesium are universal and troublesome phenomenons.Fouling can block anaerobism
Pond outlet pipe and Aerobic Pond gas distribution pipe, lead to water outlet freely not increase, dissolve hypoxgia etc. with aeration overpressure, have a strong impact on place
Reason efficiency.It has been investigated that, due to pulse water distribution, granule sludge is mixed in pond with waste water, according to two-phase mass transfer theory,
There is hierarchy in granule sludge, based on the outside hydrolysis acidification bacterium to process waste water molecule, inside is to process hydrolysis acidification bacterium
Based on the methanogen of product.The domestic pH value of micro-loop is led to rise because methanogen degrades volatile fatty acid (VFA), interior
Outside have a pH difference, and therefore calcium and magnesium plasma is in granule sludge internal precipitate.So it is not only advantageous to increase products dirty
The density of mud and particle diameter, preferably possess mud, and can delay the deposition of calcium ions and magnesium ions Aerobic Pond aeration tube etc..
6th, start soon, spoil disposal is few
Although applying anaerobic reactor of the present utility model is a granular sludge reactor, only need using common
Floc sludge is started.The utility model, under debugging, normally only takes 3～6 months systems and just can reach optimum state, shape
Ripe granule sludge system.Anaerobic sludge increasess slowly, and major part is possessed in system, and the first two years typically do not need to arrange
Mud.And most unnecessary aerobic biochemical mud can be digested, thus a large sum of Treatment of Sludge expense can be saved.Significantly reduce
The pressure of sludge treating system, reduces operating cost.
For a person skilled in the art, can technical scheme as described above and design, make other each
Plant corresponding change and deform, and all these changes and deforms the protection model that all should belong to the claims in the present invention
Within enclosing.
