中文摘要	采用umu遗传毒性测试方法考察了二氧化氯和氯消毒对几种城市污水生物处理出水遗传毒性的影响,发现当二氧化氯消毒剂从0mg/L增加到30mg/L时,几种污水的遗传毒性均先迅速降低后趋于稳定,而当氯消毒剂从0mg/L增加到30mg/L时,几种污水的遗传毒性的变化规律不同.进一步研究氨氮对污水消毒过程中遗传毒性变化的影响,发现氨氮对污水二氧化氯消毒过程中遗传毒性的变化规律没有显著影响,但是对污水氯消毒过程中遗传毒性的变化规律却起着至关重要的作用.当氨氮含量较小(<10～20mg/L)时,污水氯消毒后的遗传毒性小于消毒前;当氨氮含量较大时(>10～20mg/L),污水氯消毒后的遗传毒性大于消毒前.; The effects of chlorine dioxide and chlorine disinfections on genotoxicity of different biologically treated sewage wastewater samples were studied by umu-test. The experiment results showed that when chlorine dioxide dosage increased from 0 mg/L to 30 mg/L , the genotoxicity of wastewater first decreased rapidly and then tended to be stable, while when the chlorine dosage increased from 0 mg/L to 30 mg/L , the genotoxicity of wastewater changed diversely for different samples. It was then found that ammonia nitrogen did not affect the change of genotoxicity during chlorine dioxide disinfection of wastewater, while it greatly affected the change of genotoxicity during chlorine disinfection of wastewater. When the concentration of ammonia nitrogen was low (<10～20 mg/L ), the genotoxicity of wastewater decreased after chlorine disinfection, and when the concentration of ammonia nitrogen was high (>10～20 mg/L ), the genotoxicity of wastewater increased after chlorine disinfection.; NFSC-JST重大国际合作项目(20510076); 国家自然科学基金项目(20277025)
