Background technology
Printing and dyeing, the waste water major part that the industries such as papermaking are discharged is all the high chroma organic wastewater with difficult degradation thereby, the organism that contains the large number of biological difficult degradation in this type of waste water and there is bio-toxicity, enter environment if do not have through effective processing and can cause serious destruction to ecotope, and the health of the further harm humans of meeting.Therefore, effective processing of this type of waste water, particularly important to the protection of ecotope and the mankind's health.
The high chroma organic wastewater with difficult degradation thereby has the characteristic of colourity height and bio-refractory, and therefore, removing colourity and hardly degraded organic substance is the outstanding problem of processing this type of waste water.Mainly adopt at present chemical method, as electrolytic process, Coagulation Method, photocatalytic method, oxidation style etc., Physical, as absorption method, membrane separation process etc., biochemical process, as the combined utilization of anaerobic-aerobic technique etc. is processed this type of waste water, general traditional method is, chemical method+biochemical process+Physical is processed, but along with industrial expansion, the hardly degraded organic substance complicated component contained in this waste water, and saltiness is high, for example, due to the development of chemical & blended fabric and the progress of finishing process in printing and dye-ing technology, make the PVA slurry, the organic macromolecule of the difficult for biological degradation such as New-type adjuvant enters in dyeing waste water, biochemical poor effect, apply traditional treatment process and be difficult to reach processing effectively, and floor space is large, construction investment is high.Select effectively method to process this type of waste water very important.In recent years there are some researches show, the application electrocoagulation is processed this type of waste water, have equipment little, take up an area less, operational management is simple, decolorizing effect is obvious, part macromolecular mass organic matter degradation becomes the advantages such as subset, but effluent quality does not still reach emission standard, can only be as pretreatment process; The application photocatalytic method is processed, and its decolorizing effect is remarkable, and the COD clearance is high, thereby but colourity can reduce the ultraviolet optical transmission when too high affects photocatalysis efficiency, and within a short period of time, photocatalysis effect was not clearly.
Summary of the invention
The objective of the invention is according to the deficiency of existing treatment process and the characteristics of each treatment process, developed the integrated device of associating electrocoagulation, photochemical catalysis and active carbon adsorption technology and processed the high chroma organic wastewater with difficult degradation thereby.
A kind of device of processing the high chroma organic wastewater with difficult degradation thereby, comprise the electrocoagulation district, settling region and photocatalytic region.Electrocoagulation and photocatalytic region be in reactor head, and photocatalytic region is in the middle of two identical electrocoagulation districts, and settling region is in the reactor middle and lower part; The electrocoagulation district, in the electrocoagulation reactive tank, of insulating material, make, negative plate and the positive plate that connects respectively the direct supply positive and negative electrode is equipped with at two ends, the metal polar plate that parallel placement Fe or Al make between positive plate and negative plate, each polar plate spacing 1～2cm, bottom land is provided with mud discharging mouth; Settling region, the water inlet pipe periphery is equipped with the cylindrical baffle of top seal bottom opening, and inclined tube honeycomb filler is equipped with at top, and discharger will be precipitated in the straight-through reaction unit of spoil disposal siphon pipe bottom; Photocatalytic region, the reaction zone shape becomes rectangular parallelepiped, and what ultraviolet lamp was vertical is arranged in the middle part of reaction zone, be evenly distributed, aerating apparatus is equipped with in bottom, and parallel several zonules that is divided into, nylon wire Jiang Ci district are housed from bottom to top at a certain distance, hole pattern diameter 1cm, be placed with load TiO in each zonule
2activated carbon granule, activated carbon particle size>1cm; Water inlet pipe is equipped with in described electrocoagulation district bottom, and the electrocoagulation rising pipe is equipped with at top, and waste water flows into from water inlet pipe, enters settling region through the electrocoagulation rising pipe from described settling region water-in and continues upwards outflow after photocatalytic region is processed again by described inclined tube sedimentation.
Utilize principle, process and the advantage of this device processing waste water as follows:
Waste water enters top from bottom, electrocoagulation district and flows out, and under the conductive characteristic of the voltage effect between negative plate and positive plate and waste water, the metal polar plate both sides of parallel placement can form negative electrode and anode and electrochemical reaction occurs, and its principal reaction is as follows:
Anode: Fe-2e-Fe
2+or Al-3e-Al
3+2Cl
--2e-Cl
2↑
Negative electrode: 2H
++ 2e-H
2↑
Wherein, metal ion is further hydrolysis oxidation generation precipitation of hydroxide in water, and its effect that can play flocculation is removed partial organic substances; Cl
2the H that while reacting the ClO that generates and electrolysis with water, oxygen generates at the cathodic electricity catalytic reduction
2o
2be all strong oxidizer, can the Oxidative demage chromophoric group, oxidation macromolecule organism becomes small molecules amount organism or generates CO
2.The high chroma organic wastewater with difficult degradation thereby can decrease colourity and COD by electrocoagulation.
Waste water is after electrocoagulation is processed, contain a large amount of oxyhydroxide flcos, the electrocoagulation water outlet that will contain flco enters from the bottom, settling region, water first stops sedimentation through inclined tube honeycomb filler again at flco in the rising process after the self gravitation sedimentation, settling of floccus is more complete, effectively reduces and water suspension and turbidity.
Continue upwards to flow into photocatalytic region, photocatalyst (TiO by waste water after the inclined tube sedimentation
2) can produce " hole " effect under the irradiation of UV-light, thus H produced
2o
2, hydroxyl radical free radical isoreactivity group, its organism in can oxidizing water.Under the state of aeration, the dissolved oxygen content abundance, strengthen photocatalysis efficiency, and the waste water after electrocoagulation is processed, colourity reduces in a large number, organic composition is generally small molecules amount organism, during through photocatalytic region, the colourity of waste water is less on the impact of photocatalysis efficiency, and the activated carbon granule of loaded optic catalyst can adsorb large amount of organic, organism can have the sufficient reaction times with oxide group like this, can obtain effectively degraded by the most of organism of this process and generate CO
2.
The present invention is effectively in conjunction with electrocoagulation, photocatalytic method and active carbon adsorption, there is the advantages such as processing efficiency is high, easy to operate, whole treating processes is carried out continuously in a reaction unit, it is reasonable that each processes zone position, effectively utilized space, reduced floor space and saved unnecessary connecting pipeline.
