Description

Efficient micro-electrolysis polyphasic flow air supporting reactor
Technical field
The utility model belongs to field of waste water treatment, particularly a kind of efficient micro-electrolysis polyphasic flow air supporting reactor for poor Wastewater Pretreatment of biodegradability such as chemical industry, pharmaceutical industries.
Background technology
Chemical industry, it is high that the waste water such as pharmacy have pollutant concentration conventionally, complicated component, waste water has certain toxicity, contain the features such as component that multiple-microorganism is difficult to degraded, therefore, adopt not only difficulty up to standard of single treatment process, and investment and running cost can be very high, waste water just must be carried out to the shunting of removing contamination according to concentration, collect respectively and select physicochemical techniques targetedly to carry out pre-treatment to high-concentration waste water, reduce its toxicity and concentration and improve its biodegradability, then mix with low concentration wastewater and carry out biochemical treatment, after biochemical treatment, water outlet can reach takes over or emission standard.For high density, the waste water that poisonous, biochemical is poor, conventionally adopt chemical method to carry out pre-treatment.The effect of electroplating effluent recycling and using is the organic concentration that reduces the waste water that enters biochemical system; Decompose the hardly-biodegradable materials such as macromole aromatic hydrocarbon, improve biodegradability; Decomposition, modification hazardous and noxious substances, reduce its concentration to the biochemical scope allowing.Waste water method of chemical treatment is compared with biological treatment, can more rapidly, effectively remove more pollutent, can be used as the pre-treatment measure before biological treatment, also can be used as the tertiary treatment measure after biological treatment.This method also has equipment and easily operates, easily realizes and automatically detect and control, be convenient to the advantages such as recycling.Method of chemical treatment can be removed multiple severe toxicity and high malicious pollutent in waste water effectively.Chemical method is to utilize the work of chemical reaction in order to remove organism, the inorganics impurity in water.Mainly contain chemical coagulation process, chemical oxidization method, electrochemical oxidation process etc.Chemical coagulation process effective object is mainly small suspended substance and colloidalmaterial in water, and the cohesion and the throwing out that by adding chemical agent, produce make elimination of colloid stability form precipitation or scum silica frost and remove.Coagulation Method not only can be removed the tiny suspended particle that the particle diameter in waste water is 1O~10mm, and can also remove colourity, microorganism and organism etc., the method is subject to the variable effects such as pH value, water temperature, water quality, the water yield large, and the organic and inorganic material clearance good to some solubility is low; Chemical oxidization method normally carries out the method for oxidation removal to the organic pollutant in wastewater from chemical industry with oxygenant.Waste water, through chemistry redox, can make organic and inorganic toxic substance contained in waste water be transformed into material nontoxic or that toxicity is less, thereby reach the object of purification of waste water.Conventional have atmospheric oxidation, oxychlorination, ozonization method, micro-electrolysis method and a Fenton oxidation method.Atmospheric oxidation because of its oxidation capacity a little less than, be mainly used in the wastewater treatment containing the stronger material of reductibility, Cl is the oxygenant of common use, is mainly used in containing in phenol, processing containing organic waste waters such as cyanogen, uses ozonize waste water, oxidation capacity is strong, non-secondary pollution.Ozonation, oxychlorination method, its water treatment is effective, but energy consumption is large, and cost is high, is not suitable for processing wastewater of chemical industry with high concentration.
Micro electrolysis tech is a kind of ideal technology of processing at present high concentrated organic wastewater, claims again internal electrolysis.It is in cold situation, utilizes the iron carbon filler self being filled in waste water to produce 1.2V potential difference waste water is carried out to electrolysis treatment, to reach the object of degradable organic pollutant.
The reaction of iron carbon galvanic cell:
Anode: Fe-2e → Fe 2+e(Fe/Fe 2+)=0.44V
Negative electrode: 2H ++ 2e → H 2e(H +/ H 2)=0.00V
When aerobic exists, cathodic reaction is as follows:
O 2+ 4H ++ 4e → 2H 2O E (O 2)=1.23V
O 2+ 2H 2O + 4e → 4OH -E(O 2/OH -)=0.41V  
After system water flowing, in equipment, can form countless microbattery systems, at its action space, form an electric field.The nascent state producing in treating processes [H], Fe 2+deng can with waste water in many component generation redox reactions, such as can damaged colored chromophoric group or the auxochrome group of coloring matter in waste water, even chain rupture, reaches the effect of degradation and decolorization; The Fe generating 2+further be oxidized to Fe 3+, their hydrate has stronger absorption-flocculation activity, the molecule, metallics and the organic macromolecule that in planar water, disperse in a large number.The acting in conjunction of its principle of work based on electrochemistry, oxidation-reduction, physical adsorption and flocculation sediment processed waste water.That this method has is applied widely, treatment effect good, with low cost, convenient operating maintenance, do not need the advantages such as power consumption resource.This technique can reduce COD and colourity significantly for the pre-treatment of hard-degrading high concentrated waste water, improves the biodegradability of waste water, can have good effect to removing of ammonia nitrogen simultaneously.
The micro-electrolysis process of tradition is in the process of using, reaction product forms sealing coat can not proceed and ineffective micro-electrolysis, iron carbon filler is easy to passivation and hardens, form short circuit and channel, cause treatment effect to decline, effluent quality worsens, and for maintaining treatment effect, must change continually micro-electrolysis material, and not only working cost is high but also bring very big inconvenience to operational management.In addition, existing micro-electrolysis reactor can only be realized single micro-electrolysis reaction conventionally, cannot synchronously remove the suspended substance generating in reaction, can only remove the suspended substance in water outlet by the settler or the air-floating apparatus that arrange in addition, increased water treatment system overall cost of ownership, this has all had a strong impact on utilization and the popularization of micro-electrolysis process.
