Abstract:
UV inducing mutation technology has been used for transforming microorganism characteristic in the biologic construction,and cultivating excellent strains,which have high poison-resistance,high degradation activity and are specific and compatible in the degradation of pollutants. Since this technology can greatly reduce the time of sludge domestication and effectively improve the treatment efficiency of biological construction,it has attracted extensive interest in wastewater bio treatment. The mechanism of UV inducing mutation is introduced,and the research status of this technology in wastewater treatment,including papermaking,printing and dyeing,chemical industry,agriculture,heavy metal,etc.,is summarized. The development trend in the application of UV inducing mutation technology to wastewater treatment is pointed out.
