Disinfection of microorganisms by high-concentration disinfectants
SARS-CoV could be completely inactivated with 20 mg/L chlorine in 1 min or more, while E. coli could be inactivated by 99% in more than 5 min. However, it is so less effective in inactivation of f2 phage that could not be inactivated completely with 30 min of disinfection. SARS-CoV in wastewater could be totally inactivated for 5 min with 40 mg/L chlorine dioxide, E. coli was also inactivated up to 99.99%. However, chlorine dioxide was also less effective on inactivating f2 phage

Simple, Waste water are full of heavy metals and CL02 will react with them. So if not going to attach bacteria if is already gone.
