Abstract
The invention provides a simple effective method for processing rubber promoter production wastewater, comprising the following steps of: a) putting the rubber promoter wastewater into a quartz glass apparatus with a tubular condenser tube at the center, weighing a catalyst titanium oxide, and putting into a reactor, wherein the addition of the catalyst is 0.1-0.5g/L of the amount of the rubber promoter wastewater; b) turning on a light source of an ultraviolet lamp, stirring with a magnetic stirrer, turning on condensed water, ensuring normal temperature during the reaction process; followed by illumination for 100-150 min, sampling, centrifuging, and taking a supernatant for the determination COD. The method provided by the invention has a simple technology, is easy to operate, and can be used to effectively and thoroughly decompose organic pollutants into inorganic substances CO2 and H2O small molecules with no secondary pollution; in addition, the adsorbed catalyst is immersed in acid at a certain concentration for a certain time, and can be regenerated and reused.
Description
Technical field
The present invention relates to a kind of titanium oxide that utilizes and do catalyzer is handled rubber accelerator waste water under UV-irradiation method, belong to the rubber accelerator technical field of waste water processing.
Background technology
Produce the organism of the heterocyclic of a large amount of difficult degradations in the rubber accelerator production process, belong to the organic waste water of high-concentration hardly-degradable, molecular weight is big; Toxicity is big, and the mankind are had very big injury, therefore must just can discharge through handling; About promotor rubber industry wastewater treatment method, a lot of relevant reports has been arranged both at home and abroad, at present representative treatment process is a lot; Mainly contain physisorphtion and biochemical treatment process, these methods have played very big effect to the protection environment, but there is certain defective in these technology; Can not be completely degradable organic pollutant fully, be prone to produce secondary pollution, energy consumption is high.Document (Treatment of Industrial Water; 2007,27 (2): 30) reported that charcoal absorption handles the method for rubber accelerator waste water, this method can only simply be adsorbed onto organic pollutant in the hole of gac from liquid phase; Not degraded completely is prone to produce secondary pollution.Document (environment and health magazine; 2005; 22 (1): 28) reported efficient dominant bacteria processing rubber industry waste water; The screening of the efficient dominant bacteria of this method is more loaded down with trivial details, and mikrobe has certain requirement to nutritive substance, pH value, temperature condition, and simple to administer wastewater from chemical industry work difficulty up to standard with biochemical process big.
Through the understanding of rubber accelerator waste water that physisorphtion and biochemical process are handled, the method for physical adsorption in the industry can not be degraded organism completely; But be organic pollutant that the form of another kind of phase exists from a kind of phase transition, therefore environment still there is certain pollution, and biochemical treatment process; Must from occurring in nature through domestication, enrichment, screen, cultivating one's ability filters out dominant bacteria; Perhaps produce bacterial classification efficiently through assortment of genes technology, biological process processing efficiency in the ability raising system, the screening of dominant bacteria is cumbersome a kind of process; Biochemical treatment process is comparatively complicated; Operation is stable inadequately, and therefore, exploitation is efficient, less energy-consumption, the technology that can thoroughly degrade organic pollutant fully are the targets that green technology is pursued always.
Summary of the invention
The object of the present invention is to provide a kind of method of simple and effective processing rubber accelerator factory effluent, can overcome the shortcoming of prior art.Present device technology is simple, and is easy to operate, and condition is loose, non-secondary pollution, and catalyzer can be reused, and is a kind of organic method in the waste water of removing effectively.
In order to achieve the above object, it is ultraviolet source that the present invention adopts the 365nm uv lamp, and catalyzer is the meso-porous titanium oxide nano particle; The aperture is at 5～10nm particle, and the mensuration of COD adopts potassium dichromate process, and section steps the rubber accelerator waste water that chemical industry ltd produces to wastewater source in Tianjin; The addition of catalyzer is for measuring at 0.1～0.5g/L; Behind reaction times 100～150min, COD tends to be steady, and basically no longer changes; The operating process of this invention comprises following scheme:
A) rubber accelerator waste water is put into the middle silica glass instrument that has the tubulose prolong, take by weighing the catalyst oxidation titanium, put into reactor drum, the addition of catalyzer is 0.1～0.5g/L of rubber accelerator wastewater flow rate;
B) open ultraviolet light source, under magnetic stirring apparatus, stir, open water of condensation, guarantee that temperature is a normal temperature in the reaction process.
C) behind illumination 100～150min min, it is centrifugal to take a sample, and gets supernatant liquid and measures COD.
The invention has the advantages that: technology is simple, and is easy to operate, can effectively thoroughly decompose organic pollutant, and organic pollutant degradation is inorganics CO
2And H
2The O small molecules, non-secondary pollution, the catalyzer of absorption soaks the regular hour in certain density acid, and catalyzer just can obtain regeneration, and catalyzer can be reused.
The method that we adopt; Can effectively degrade organism in the rubber accelerator waste water; The irradiation of UV-light has certain promoter action to handling rubber accelerator waste water; Under the effect of catalyzer, organic pollutant materials such as MBT, benzothiazole, aniline can obtain oxygenolysis completely.With the uv lamp is light source, under the effect of catalyst oxidation titanium, can decompose organism completely, and we had both overcome the transfer of organism phase in the physisorphtion process, has avoided the process of the loaded down with trivial details strain screening of microorganism treatment again.Compare with traditional treatment process, advantage such as that photocatalysis degradation organic contaminant has is easy, easy to operate, non-secondary pollution, catalyzer can be reused is an organic method in a kind of effective removal waste water.
