Description
Technical field
The present invention relates to a kind of Industrial Wastewater Treatment equipment, relate in particular to the equipment that a kind of assembled unit formula catalysis ozone method is handled trade effluent.
Background technology
Along with the high speed development of China's economic situation and the raising day by day of living standards of the people, the generation of trade effluent and intractability also increase thereupon.Industries such as especially pharmacy, chemical industry, coking, oil refining, plastics, printing and dyeing, the organic pollutant that contains a large amount of poisonous and harmfuls and be difficult to degrade in its waste water, as phenols, polycyclic aromatic hydrocarbons, organic nitrogen compound, organic chloride, heterogeneous ring compound etc., its value volume and range of product sharply increases, the waste water that contains these pollutents has color, stink or easily gives birth to foam, the concentration height, variation water quality is bigger, is difficult to stably reaching standard through general traditional biochemical process.Therefore, must cooperate just with other treatment technologies and can reach processing requirements.
At present, advanced oxidation processes is research and the application focus of handling at Persistent organic pollutants.By used oxygenant and the difference of catalytic condition, high-level oxidation technology generally includes Fenton reagent method, conductor photocatalysis oxidation style, sonochemistry oxidation style, wet oxidation process, supercritical oxidation process, ozone method etc.Wherein, the ozone method is to be applied to one of engineering practical methods the earliest.
Ozone not only can be sterilized, and also can reduce COD, BOD, also has effects such as decolouring, deodorizing, taste removal, sterilization, sterilization; The reaction conditions gentleness can be reacted at normal temperatures and pressures; Ozone has extremely strong oxidation capacity as strong oxidizer simultaneously, becomes oxygen after the decomposition, be difficult for producing secondary pollution, and be safer wastewater processing technology.
In the aqueous solution, the oxygenizement of ozone realizes by two kinds of reaction mechanisms, first kind is direct reaction, ozone utilizes its strong oxidizing property directly and the organic pollutant contact reacts, position of double bond generation selectivity addition reaction at organic molecule changes organic chemical structure, and unsaturated hydrocarbons is converted into stable hydrocarbon, the material of macromolecule is converted into the material of small molecular weight, makes the organic matter degradation in the waste water.This chemical reaction has selectivity, and the order of oxidation is: alkene＞amine＞phenol＞polynuclear aromatics＞alcohol＞aldehyde＞paraffinic hydrocarbons.Second kind is indirect reaction, and at normal temperatures and pressures, ozone when adding catalyzer, can produce more hydroxyl radical free radical OH in the short period of time by producing the reaction of hydroxyl radical free radical OH and organic pollutant, improves speed of reaction.Hydroxyl radical free radical OH chemical property is very active; has higher redox potential and electron affinity energy power; it is the very strong group of a kind of oxidisability; in wastewater treatment process; it can react by mode and the organic pollutant of electrophilic addition, dehydrogenation, transfer transport; reaction rate constant is 108～1010molL-1s-1, and level of response is more thorough.After hydroxyl radical free radical OH reacted as secondary oxidation agent and organic pollutant, the organic free radical of generation can continue to participate in the chain reaction of hydroxyl radical free radical OH, perhaps by the organo-peroxide free radical that generates oxidative decomposition took place further.By the means of O3 catalytic oxidation, can directly make the organic pollutant mineralising, make the water outlet water quality reaching standard, also can reduce its toxic, thereby improve biodegradability, in order to be for further processing.
Organism in the metal oxide oxidation catalyst ozone oxidation method degradation water has dropped into practice, difference according to catalytic way, O3 catalytic oxidation can be divided into dual mode: a kind of is to utilize GOLD FROM PLATING SOLUTION to belong to the homogeneous catalysis ozone oxidation of ion, the intervention of metal ion can accelerate ozone decomposition, strengthen and produce free radical isoreactivity intermediate to improve the oxidation capacity of ozone, also strengthened the utilization ratio of ozone greatly, defective is to have the stripping problem that the back underwater gold belongs to ion of handling, especially cobalt-containing catalyst, this can reduce the work-ing life of catalyzer, its utilization ratio is reduced, also may cause secondary pollution, operation and maintenance cost is higher.Another kind is solid metal, metal oxide and loads on metal on the carrier or the heterogeneous catalysis ozonize of metal oxide, on profile, can be divided into ball-type, column type or spongiform etc., this method good stability is not easy to run off, do not introduce secondary pollution, need not subsequent disposal, the renewable repeated use of catalyzer etc. reduce but contact area is corresponding, internal diffusion speed is slower, and speed of reaction descends thereupon.
When using, common ozone method engineering in the time of short term contact, only can remove the aromatics that part contains unsaturated double-bond, though the oxidation capacity of ozone is strong, but can not carry out oxide treatment fast and effectively when handling the complicated and stable Persistent organic pollutants of chemical structure, efficient and effect are not very desirable.
Therefore compare with common ozone oxidation method, the O3 catalytic oxidation technology combines the strong oxidizing property of ozone and characterization of adsorption, the catalysis characteristics of catalyzer, can solve the common process organic pollutant than the problem of difficult degradation, speed and efficient are higher, can obviously strengthen the removal ability that aromatics, nitrogenous compound and heterocyclic compound etc. is had the organic pollutant of potential toxic, strengthen the ozone oxidation method to organic destructive force and inorganicization degree, also can reduce the content of disinfection byproduct (DBP) that follow-up cholorination technology forms such as trichloromethane etc.
The O3 catalytic oxidation method can have boundless application prospect for the treatment of various industrial sewage.The part but it also still comes with some shortcomings at present.
The one, the catalyst utilization problem, existing solid ozone oxidation decomposition catalyst mainly contains elemental metals (Mn, Zn, Fe, Cu, Ni etc.), metal oxide (MnO
2, ZnO, TiO
2Deng) or the mixture (Al of metal oxide and other materials
2O
3/ TiO
2, C/TiO
2Deng).Precious metal since expensive price limit its application, the elemental metals solid catalyst is decomposed by ozone oxidation easily, catalyst utilization is low; The composite strength of metal oxide or metal oxide and other materials is low, easily broken, cause the life cycle of catalyzer short, and the strong adsorption in target contaminant and metal oxide catalyst surface causes the catalyst activity reduction in the water body, scrubbing efficient only is 70～80%.
The 2nd, the reaction efficiency problem, can the ozone that ozonizer provides fully be used under the effect of catalyzer, mainly determined by the ozone oxidation reaction device, O3 catalytic oxidation method wastewater processing technology, relate to the solid, liquid, gas three-phase, reaction environment is comparatively complicated, and the many influence factors such as adsorption in the reaction process between the pH of water, temperature, catalyzer, material are wayward, can have influence on reaction efficiency.
The 3rd, ozone reactor equipment cost problem, most of reactor all need carry out particular design at different engineerings, and volume is bigger, and rather heavy, the internal structure complexity is difficult to extensive mass and puts into production, thereby equipment cost is higher relatively.
In sum, the effect of O3 catalytic oxidation is no doubt excellent, but still it is low to exist ozone utilization rate, catalyzer easily runs off, and speed of reaction is not high, and power consumption is big, investment cost and capital construction cost are higher, process matched therewith and technology are improved and the Waste Water Treatment security problems inadequately, and therefore, how effectively to address the above problem is the key that catalysis ozone technology is further applied.
