Description
Technical field
The invention belongs to microbial technology field, be specifically related to a kind of preparation for the treatment of sulfuration class material in transformer oil.
Background technology
Transformer (Transformer) utilizes the principle of electromagnetic induction to change the device of voltage of alternating current, along with the generally application of transformer, the a large amount of electroplating wastewaters producing the generation of this transformer must arouse enough attention, the waste water etc. that electroplating wastewater main source has the rinse water of plating piece, useless electroplate liquid, plating shop ground flushing water and plating piece surface treatment to produce, its complicated component, general containing heavy metal ion and prussiates such as chromium, nickel, copper, zinc, gold and silver, toxicity is very strong, huge to the destruction of environment.
The treatment process of prior art to electroplating wastewater is generally following several:
1, solvent extration
Solvent extration be utilize heavy metal ion organic phase and in water the difference of solubleness, make heavy metal concentrate in the separation method of organic phase.Organic phase also claims extraction agent, common are tributyl phosphate, trioctylphosphine oxide, diformazan heptyl ethanamide, trioctylamine, primary amine, oleic acid and linolic acid etc.In addition, in metal form analysis, organic extractant is also widely used, as acetone, ethanol etc.Solvent extration process heavy metal wastewater thereby equipment is simple, easy and simple to handle, and it is little to add extraction dosage, and the recyclable recycling of extraction agent, secondary pollution is little, is a kind for the treatment of process having very much development potentiality.
2, chemical precipitation method
Chemical precipitation method is the principle according to solubility product, adds oxyhydroxide, sulfide, carbonated etc., heavy metal ion and hydroxide ion, sulfonium ion, carbanion etc. is combined and forms insoluble compound.Although technique is comparatively simple, operation is also than being easier to, and this method is subject to the impact of precipitation agent and envrionment conditions, makes aqueous concentration not reach emission standard.In addition, if a large amount of waste residues that reaction produces well are not processed, easily produce secondary pollution, do not meet the principle of environmental protection.
3, ion exchange method
Ion exchange method is the process of heavy metal ion and ion exchange resin generation ion-exchange, and resin property heavy metal is removed considerable influence.Conventional ion exchange resin has Zeo-karb, anionite-exchange resin, resin and Humic Acid Resin etc.Ion exchange method is optionally heavy-metal ion removal, and technique is simple, easy and simple to handle, and removal effect is fine.Compare with electrolytic process with the precipitator method, ion exchange method has certain advantage in the wastewater treatment of lower concentration, but this method is by the loading capacity of resin, the useless impact of impurities in water and the restriction of exchanger kind, output and cost, and higher to the pre-processing requirements of waste water, the process of regeneration of ion-exchange resin and regenerated liquid is also an insoluble problem.
4, absorption method
Absorption method is in fact the attraction of adsorbent activity surface heavy metal ion, is the adsorption utilizing porous solid material, makes the heavy metal ion adsorbed a kind of method removed at solid adsorbent surfaces in waste water.The most frequently used sorbent material is gac, but it is expensive, and work-ing life is short, and need regeneration, process cost is high.In addition, absorption method process heavy metal-containing waste water is applied widely, can not cause secondary pollution, but the adsorption selectivity of sorbent material often heavy metal ion is not high, can not well be promoted.
National environmental protection portion requires that electroplating industry need discharge according to GB21900-2008 " plating pollutant emission standard ", use the electroplating wastewater of conventional disposal methods complicated component, be difficult to shunting thoroughly, be difficult to process up to standard, biochemical difficulty, or need by transformation of facility or multiple-stage treatment etc., such medicine dosage is large, technique repeat produce mud also many, cost is high, be also difficult to guarantee sewage qualified discharge.Therefore, develop that a kind of construction investment is few, running cost is low, the method for the place to go transformer electroplating wastewater of good treatment efficiency is extremely urgent.
