摘要

Inactivation of Giardia and Cryptosporidium parvum oocysts by ozone was performed in ozone demand-free 0.05 M phosphate buffer (pH 6.9) in bench-scale batch reactors at 22 deg C . Crytposporidium was also investigated at 7 deg C . Ozone was added to each trial from a concentrated stock solution for contact times ranging fron 5 to 15 min. Viability of the control and ozone-treated parasites was determined using naimal infectivity. The mongolian Gerbil model was used for Giardia lamblia and the neonatal CD-1 mouse model was used for Cryptosporidium parvum.
