Abstract
The utility model belongs to the field of water treatment, and particularly relates to a biological reaction device for fluidifying biological filling materials under the action of directional air lift circulation. Flow guiding devices are arranged in the biological reaction device and divide the biological reaction device into a plurality of sub reaction zones; the upper parts as well as the lower parts of the sub reaction zones are communicated with one another; and the directional air lift circular flow of water to be treated is realized under the action of air lift by alternately aerating the sub reaction zones, that is, the water to be treated flows up in aerated sub reaction zones and flows down in non-aerated sub reaction zones. The flow rate of the air lift circular flow is generally much greater than that of the water to be treated, so that the water flow drives the filling materials of a fluid bed to circulate over and over again among the aerated and the non-aerated sub reaction zones; owing to the directional control of the air lift circular flow, the fluidification effect of the filling materials is better, and the filling materials with larger sizes are enabled to flow effectively; and as about half of the reaction zones are aerated, the aeration amount can be greatly saved.
Description
Technical field
The utility model belongs to water treatment field, particularly a kind ofly carries the biological reaction apparatus that Circulation makes the biologic packing material fluidization through directed gas.
Background technology
Along with Economic development, mankind's activity is more and more serious to the pollution of water, and water resources is more and more poorer, thereby human society is also increasingly high to the requirement of water purification, WWT and regeneration effluent technology.Putting before this, novel sewage disposal technology and method are also more and more important.
There are problems such as active sludge is prone to run off, sludge activity is low in anaerobism, anoxic and aerobe reactor in traditional sewage water treatment method.The biologic packing material technology can be fixed on filling surface with mikrobe, and the realization current separate with living microorganism on the spot, are most important methods that improves bio-reactor efficient.Yet brought between filler the space easily by sludge blockage when improving the efficient of bio-reactor, influence the technical problem such as even mobile of water and gas with biologic packing material.
Sludge of sewage treatment plant is handled has become thorny problem of environmental pollution gradually.Lowering the sludge of sewage treatment plant quantity discharged is the new problem that sewage disposal technology faces.In fact the overwhelming majority of WWT discharging mud is made up of mikrobe, mikrobe corpse or mikrobe corpse fragment.The overwhelming majority of these compositions can be by biochemical degradation.Yet WWT mud contains various bacteria, bacterium corpse or bacterium corpse fragment, and these mud of degrading need complicated biochemical system.
The characteristic of thermopnore biological reaction apparatus is that wherein biologic packing material is ciculation fluidized state, and the aged microbial film is prone to come off in this biological reaction apparatus, makes the microbial film on the biologic packing material keep higher activity; The mobile touch opportunity that has increased mikrobe and oxygen and pollutent of while filler, thereby higher biochemical efficiency is arranged.
Generally in aerobic biological reaction apparatus, add the thermopnore biologic packing material in the known technology, the thermopnore biologic packing material is carried at gas and is realized under the cycling stream effect circulating.The proportion of thermopnore biologic packing material in water should be as far as possible near 1.0g/cm
3, usually between 0.9-1.2g/cm
3Between.
Known technology floatation type composite gap biological filler (one Chinese patent application 201020610692.9) comprises a netted shell of hard and is filled at least a a plurality of medium blocks in the said shell, it is characterized in that proportion is between 0.8-1.0g/cm in the whole water of biologic packing material
3Between, use this kind biologic packing material not only to be applicable to the thermopnore bio-reactor, and can utilize the anoxic of existence in the filler and the performance realization sludge reduction that anaerobion is degraded to biological sludge.
Yet, because being provided with usually of aerating apparatus of Aerobic Pond bottom can't effectively be controlled the flow direction and the intensity that gas is carried cycling stream, therefore often produce problems such as biologic packing material fluidisation property difference and filler " block up ", influence the biochemical effect of thermopnore.
Summary of the invention
The utility model will solve the relatively poor technical problem of thermopnore filler fluidized state in the known technology; Through be provided with several up and down all the guiding device of UNICOM reactor drum is isolated into the experimental process reaction zone of intercommunication up and down; Each sub-reaction interval is proposed the orientation control of cycling stream at a distance from the technological method realization gas of aeration, thereby strengthen the fluid effect of mobile filler.
In order to address the above problem; The directed cycling stream movable bed of the utility model biological reaction apparatus comprises a biological reaction tank; At least one water-in, at least one water outlet is filled in the inner thermopnore biologic packing material of biological reaction apparatus; One is produced the water guiding device, and at least one that is installed on the said product water guiding device produced water grid and at least one mud valve; Said product water guiding device is divided into reaction tank and produces water precipitation district and biochemical reaction zone; Said product water grid flows into product water precipitation district in order to intercept filler; The settled mud in said product water precipitation district can be discharged through said mud valve.It is characterized in that; Also comprise at least one guiding device at this reactor drum; Be installed at least two group aerating apparatuss of reaction tank bottom and at least two the aeration valves corresponding respectively with said at least two group aerating apparatuss; Said at least one guiding device is isolated at least two sub-reaction zones with biochemical reaction zone, the equal up and down UNICOM of said each sub-reaction zone; Said at least two group aerating apparatuss are corresponding respectively with at least two sub-reaction zones; Realize the separated aeration of at least two sub-reaction intervals through the switch of said at least two aeration valves, can also realize the mutual switching of sub-reaction zone of aeration and the sub-reaction zone of non-aeration and keep the sub-reaction zone continuous aeration adjacent to block up at product water grid place to avoid filler with producing the water guiding device through the switch of said at least two aeration valves.
The directed cycling stream movable bed of the utility model biological reaction apparatus beneficial effect be through to each sub-reaction interval at a distance from aeration, make processed water gas carry effect down the directed gas of realization carry cycling stream, promptly at the sub-reaction zone of aeration to the upper reaches, in the non-aeration subarea to dirty.The flow that this gas is carried cycling stream is far longer than the flow of processed water usually, thereby realizes the repeatedly circulation of water flow drives current downflow bed fillers at aeration reaction zone and non-aeration reaction interval.Because gas is carried cycling stream and obtained directed control, thereby the fluid effect of filler is better, make that the bigger filler of volume is able to effectively flow; Because aeration in half the approximately reaction zone only, thereby aeration rate can significantly be saved.
