Description
Technical field
The present invention relates to the processing method of a kind of brine waste.
Background technology
At present, many areas, particularly some arid areas and coastal area, shortage of water resources problem grows in intensity, the situation the most in short supply in order to alleviate freshwater resources, water for industrial use and domestic water have been carried out being directly used in sea water in some coastal areas, and this but causes the generation of waste water of substantial amounts of high salinity.The brine waste of industrial discharge is possibly together with substantial amounts of poisonous persistent organic pollutants, if directly discharged by this brine waste, environment will bring extremely serious impact.
Electrochemical oxidation decontamination is the method utilizing electrolysis to realize oxidative degradation organic pollution, and the equipment of electrochemical oxidation is simple, controls flexibly, such as two dimension electrolysis unit.
But the organic pollution in waste water is processed by the two-dimentional electrolysis unit generally used, preferable treatment effect can not be obtained, and there is time-consuming long defect.
Summary of the invention
It is an object of the invention to provide and overcome organic pollution present in the processing method of existing brine waste to be difficult to remove and the time-consuming defect such as long, it is provided that a kind of processing method that can remove the organic pollution in brine waste and process time shorter brine waste efficiently.
The present inventor finds through further investigation, compared with traditional heating means, uses microwave heating technique to process Organic Pollutants in Wastewater and has the advantages such as quick, efficient, free from environmental pollution.At present, microwave technique application mainly has three kinds in the mode that waste water processes: the first is first to be adsorbed onto on absorbing material by the pollutant in waste water, is then taken out by absorbing material and is placed in microwave field radiation, makes the contaminant degradation of absorption；The second is that the waste water that direct microwave radiation contains absorbing material is degraded；The third is and being used in combination of other technologies, including with the combining of NaClO, Fenton, photocatalysis etc..Said method all there are organic pollutants for the process of brine waste to be difficult to remove and the time-consuming defect such as long.
