Description
Technical field
The electricity that the utility model relates to a kind of firer's of processing medicament factory effluent causes three-dimensional three-phase fluidization oxidation bed, particularly a kind of crucial treatment unit of firer's medicament factory effluent, a kind of especially environment-protection wastewater treatment unit.
Background technology
Can produce a large amount of waste water in the production processes such as firer's medicament dinitrodiazophenol, trinitro-resorcinol; This type waste water principal pollutant are COD (COD), colourity, dinitrophenols etc.; And nitropheneol contains benzene ring structure; Chemicalstability is high and have toxicity, is different from general organic waste water fully.Many firer's medicaments enterprise can not be perplexed by qualified discharge for COD and nitropheneol for a long time.
Firer's medicament factory effluent is the difficult problem that domestic and international WWT is faced always, thereby also is the heat subject of domestic and international Recent study.Up to the present, the treatment process of this type factory effluent roughly has following several kinds:
● absorption method
Absorption method is to utilize the adsorption of porous masses such as gac, coal to remove pollution.But the regeneration of sorbing material is a problem; Regeneration waste liquid needs to handle if the employing medicament is regenerated; If the employing thermal regeneration need be heated to more than 600 degree and could thoroughly remove adsorbed contaminants, therefore adsorb complicacy and the running cost that the regeneration of adopting material increases technology undoubtedly.But sorbing material is not regenerated, and new sorbing material price is expensive again.
● method of evaporation
Method of evaporation is to send factory effluent to boiler to carry out evaporation concentration, and residue is mixed coal and burned.This method processing power is little, long processing period, and energy consumption is high, the basic suitability for industrialized production needs that adapted to not.
● the ozone oxidation method
The ozone oxidation method is the nitrophenol that utilizes in the ozone oxidation waste water.But because the existence of phenyl ring and nitro makes that these material chemicalstabilities are high, be difficult to thoroughly, ozonize current consumption is big, cost is high, and ozone is toxic, and solubleness is low in water, and utilization ratio is not high.
● biochemical process
Biochemical process is to utilize the metabolism of mikrobe that the organism in the waste water is decomposed; But because this waste strength is high; And the ratio of BOD/COD belongs to the organic waste water of bio-refractory less than 10%, therefore directly adopts biochemical process to handle this waste water and has little effect.
● electrolytic process
The electrolysis ratio juris is with the cathodic area of waste water as for electrolyzer, makes nitrophenol be reduced into aminocompound, is carrying out oxidation through the positive column then; Make it resolve into simple and stable inorganic salt; The shortcoming of this method is that energy consumption is high, and intermittent type is handled, and is not suitable for the suitability for industrialized production needs.
● Fenton reagent method
Fenton reagent method is a kind of advanced oxidation processes to the hardly degraded organic substance treating processes; To handling ability organic wastewater with difficult degradation thereby such as phenols, arylamine class certain effect is arranged; But the characteristic of firer's medicament factory effluent is high density, high suspended matter, organism nearly all is nitropheneol, is very considerable if adopt Fenton reagent method medicament expense therefore.
● iron charcoal micro-electrolysis method
Iron charcoal micro-electrolysis method be waste water under acidic conditions, with iron do anode, charcoal is done negative electrode and in water, is formed numerous small galvanic cell, these batteries have electrolytic action, can oxidizing water in part inorganics and organism.But these galvanic cells are very faint, thus nearly all be that firer's medicament factory effluent effect of nitropheneol is very little to high density, high suspended matter, organism, and also the reaction times is extremely long, more than 24 hours.
Summary of the invention

The principle of the utility model is: under the tart condition, the gac and the cast iron that are filled between the battery lead plate form a large amount of galvanic cells, have little electrolytic action; Between battery lead plate, add a low-voltage dc voltage; Strength of electric field between the battery lead plate is increased, and electric energy increases, the O that the outside provides
2Capture the electronics that extra electric field provides, form the oxyradical ion, this ion generates H through after a series of chain reaction
2O
2, H
2O
2Add outside under the effect of electronics and metals ion, only this is in the hydroxyl radical free radical of fluorion to excite the generation oxidisability, and hydroxyl radical free radical makes organism decomposition, mineralising.Be arranged on a gas distribution system of body bottom except providing oxidation required O
2, also for three-phase fluidization provides power, waste water and Air mixing liquid from bottom to top make the filler fluidisation with certain speed during through packing layer, realize that gas-liquid-solid three-phase fully contacts, and has improved processing efficiency.
Electricity causes three-dimensional three-phase fluidization oxidation bed in entire reaction course; Extra electric field is the effect of " safety fuse ", is different from electrolytic process fully, and electrolytic process is that pollutent is in anode and negative electrode generation redox reaction; Be converted into innoxious substance and separated, so the electrolytic process energy consumption is very high.
