Abstract

The invention discloses a method for processing organic contaminated waste water. The method is characterized by comprising the following steps: under effect of microwave radiation and supersonic wave, under existence of a photocatalyst, processing the organic contaminated waste water through ultraviolet irradiation, wherein, the microwave frequency of microwave radiation is 900-2500 MHz; the supersonic wave frequency is 20-60 kHz; and the ultraviolet light wavelength is 250-370 nm. In the method for processing the organic contaminated waste water, through combination of the microwave radiation, the supersonic wave and photocatalysis, the synergism is obvious, photocatalysis oxidation treatment is carried out on organic pollutants of the organic contaminated waste water can be better carried out, so that COD and BOD5 of the organic contaminated waste water are reduced to low values, and the processing time is short.

Description

technical field [0001] The invention relates to a method for treating organic polluted wastewater. Background technique [0002] With the rapid development of cities and modern industries, the types and amounts of artificially synthesized organic substances are increasing day by day, which also brings serious environmental pollution problems. The traditional biodegradation method is usually used to degrade the organic pollutants in organic polluted wastewater. However, for the degradation of highly toxic organic pollutants, the traditional biodegradation method has poor performance and needs to be carried out at a suitable ambient temperature. , making it difficult to completely convert organic pollutants into CO 2 And water, and its treatment time is relatively long; especially for saline wastewater with high salt content, it is not suitable for the survival of microorganisms, so it is difficult to use biodegradation to treat organic pollutants in saline wastewater. In ad...
