%X The effects of chlorine dioxide dosage and reaction time on the acute toxicity and genotoxicity of wastewater after chlorine dioxide disinfection were studied using photobacterium bioassay and umu test. The experiment results showed that with the increase in chlorine dioxide dosage, the acute toxicity increased, but the genotoxicity decreased and then became stable. With the increase in reaction time, the acute toxicity increased to a peak and then decreased, but the genotoxicity decreased and then tended to be stable. Because the effects of disinfection conditions on wastewater acute toxicity and genotoxicity are quite different, it was considered that the substance contained in the wastewater with acute toxicity and the substance with genotoxicity were different, and there was a range of disinfection conditions to make both the acute toxicity and the genotoxicity low.
