Description
Technical field
The utility model relates to a kind of micro-electrolytic water treatment unit.
Background technology
Micro-electrolysis method is to utilize Principles of Metal Erosion, forms the good process that galvanic cell is handled waste water, claims internal electrolysis, iron dust filtration method etc. again.Because applied widely, advantages such as treatment effect good, long service life, with low cost and convenient operating maintenance that this method has, and can use waste iron filing etc. to be raw material, also need not consume electric power resource, have the meaning of " treatment of wastes with processes of wastes against one another ".Micro-electrolysis method successfully is applied to the processing of waste water such as dyestuff, printing and dyeing, heavy metal, agricultural chemicals, pharmacy, oil content at present.Existing little electrolytic processing apparatus exposes some problems in operational process, fixedly the little electrolytic processing apparatus of filler is after the operation of for some time, and filler easily lumps, and phenomenons such as channel occur, reduces treatment effect greatly.Though fluidized-bed has solved agglomeration problems, for guaranteeing fluidized, filler needs constantly circulation, and power consumption is bigger, and filler runs off easily.
Summary of the invention
It is little that technical problem to be solved in the utility model provides a kind of filler consumption, follow-up in and the few and packing layer prevented from caking of throw out that produces of coagulative precipitation stage, the fluidized-bed micro-electrolysis device that power consumption is little.
The technical solution of the utility model is: micro-electrolysis device for aeration fluidized bed, comprise that a body, bed body are near the water inlet pipe of upper end one side, the rising pipe of the relative side with water inlet pipe in the close upper end of bed body, the porous support plate of an intravital filler bottom, bed body top is near the effluent weir of rising pipe, the dividing plate that is provided with a bottom perforate in the middle of the bed body is divided into two chambeies with bed body inside, the bottom in two chambeies is set to the bucket shape structure respectively in the bed body, two high-pressure air pipes is arranged respectively from the external bottom that feeds two chambeies in the bed body of bed.
The top of filler is provided with grid in the bed body, and grid is provided with mesh, and the mesh that is provided with on the grid is a circular hole, also can be rectangular opening.Filler is an iron-carbon filling material in the bed body, also can be the alferric carbon filling material.The material of bed body is rubber-plastics materials such as PVC, PP, or is Reinforced Concrete Structure, steel construction, inner lining glass fiber reinforced plastic and rubber-plastics material.The mouth down that goes out of two high-pressure air pipes bends towards a body bottom.Several these devices can use or be combined into the device that is fit to handle the different water yields, water quality by series, parallel.
Beneficial effect: the utility model is by being the bucket shape structure in bottom design, the long-time back of reaction filler particles diminishes gradually, mesh through back up pad enters the bucket end, adopt tracheae to impact the bucket end downwards, make the fine particle that falls to the bucket end be in fluidized state, unlikely hardening, and can micro-electrolysis reaction further take place with waste water, consume until total overall reaction, make the upper strata filler under the air-flow buoyancy function, produce the fluidisation friction simultaneously, fully contact, remove simultaneously attached to the solids on the filler with waste water.Improve oxygen in water concentration on the one hand, help the generation of free radical and the generation of redox reaction; Avoid filler to harden on the other hand and improve the flux of waste water.When the air that enters floats filler, can make filler produce tangible layering, particle increases successively from top to bottom, and can make to be subjected to impacting attached to the passive film on the filler, poly-shape thing, particle etc. and removed.Adopt the aeration fluidisation to compare with the rotating cylinder fluidisation simultaneously, reduced power consumption, greatly reduce running cost with mechanical stirring.This device water inlet and water outlet adopt grid, intercept impurity accesss to plant such as fiber, and avoid filler to run off.Because make the little filler particles that falls to the bucket end be in fluidized state at the bottom of the air blast bucket, the single step reaction of going forward side by side consumes, so this device need not deslagging basically.
