Description
Technical field
The sewage treatment equipment that the present invention relates to be used for the catalyzer of wastewater treatment and use this catalyzer, light auxiliary catalysis mineralizing and degrading organic pollutant.
Background technology
The organic waste water contaminate environment, the existence of the influence mankind and other biological also hinders Economic development; The control pollutant emission is the guarantee of sustainable economic development.Organic waste water brings serious harm for our living environment, and wastewater toxicity height, difficult degradation, the residence time of especially containing aromatic nitro compound and phenolic compound are long, and be dark to natural harm; Therefore, the America and Europe has stopped producing TNT.Method of wastewater treatment has biological treatment, burn processing and electrooxidation method etc. usually.Biological treatment comprises aerobic treatment method and anaerobic treatment method, or both junction logos.Usually use activated sludge that microorganism is provided, biological treatment can be handled some organic waste waters; But, can not handle the organic waste water of high density, can not handle and contain nitro-compound and contain waste water with certain toxic chemical.In addition, microorganism treatment need be appropriate to the temperature of biological existence, and for China's southern area, the temperature in summer is higher, and the temperature in winter is lower, and the effect of microbiological treatment is undesirable; For the most of northern area of China, the temperature in winter and spring is lower, and microorganism almost can not survive, and can't handle waste water; If give processed waste water heating, increased the expense of handling waste water so undoubtedly.In addition, microbiological treatment waste water produces mud, regularly removes mud and makes troubles for a large amount of organic waste waters of handling.Generally, the complicated component of organic waste water not only contains different types of organism, may contain the deleterious compound of microorganism, and, may also contain the inorganic salt of higher concentration; These factors all are unfavorable for using the biological process degradation of organic waste water.
The method of burn processing waste water uses heavy oil to act as a fuel usually.But oil price goes up exponentially in recent years, and the cost that makes original expense handle waste water with regard to the method for very high burn processing waste water rises violently, and enterprise can't accept.And, when burning, nitrogenous organic waste water generates nitrous oxides exhaust gas, cause secondary pollution.
In recent years, anodizing method, High Temperature High Pressure oxidation style, membrane permeation method and supercritical oxidation process etc. have been reported in research.At present, all there are some limitation in these methods, especially are not suitable for handling on a large scale trade effluent.
Discharging again after the treatment of Organic Wastewater recycles after perhaps handling, and is the assurance that social development continues, and is the assurance of human society existence.Generally, the complicated component of organic waste water not only contains different types of organism, and, may also contain the inorganic salt of higher concentration, make the unusual difficulty of processing of waste water, even some method is invalid.
It is the method for oxidation processing waste water of catalyzer with cupric oxide or nickel oxide that JP-A-4994157 proposes a kind of.JP-A-4944556 proposes a kind of palladium and platinum even load used on carriers such as activated carbon, silica gel, aluminum oxide, catalyzed oxidation organic waste water.The efficient that these methods are handled waste water is not high, and the poor durability of catalyzer, has bigger limitation aspect practical.The patent CN101045204A wet oxidation that proposed a kind of High Temperature High Pressure handle the method for organic waste water, some metals or its compound are as catalyzer, under High Temperature High Pressure, make the organic matter degradation in the waste water, the remarkable shortcoming of the wet oxidation process of High Temperature High Pressure is that the expense of the processing waste water that High Temperature High Pressure is brought is higher, also be not easy to enlarge wastewater treatment capacity, these two shortcomings make that this technology is impracticable.CN1994546A proposes catalyst cupport on macroporous silica gel, activated alumina or permutite, uses three-phase circulating fluidized bed photocatalytic degradation organic waste water method.Preparation of catalysts is comparatively complicated, has bigger limitation aspect practical.Patent 200610007233 proposes the electrochemical oxidation facture, at first uses solids and inorganic salt in the apparatus for electrochemical treatment filtering waste water, again the organism in High Temperature High Pressure lower electrode oxidized waste water.This method process for the treatment of waste water complexity, the cost height, efficient is low, and equipment also is difficult for amplifying, and wastewater treatment capacity is restricted.Patent CN1528513A and CN1508073A propose the fixed bed photocatalytic reaction device, and it is high and be difficult to handle in a large number the problem of waste water that this technology exists the processing efficiency of waste water.
The organic waste water contaminate environment, the existence of the influence mankind and other biological also hinders Economic development; The control pollutant emission is the guarantee of sustainable economic development." Eleventh Five-Year Plan principal pollutant total amount reduces discharging evaluation method " write instructions and transfer by State Council.Therefore solve deleterious waste water, useless quarrel, off gas treatment problem and become one of extremely urgent task of country.
