Study on the removal of toxic substance from river water using O3-GAC process

This paper studied on the removal of toxic substance from river water using O3-GAC process. The result of GC/MS analysis indicated that the number of organic compound species was decreased by 55. 1%. The species of toxic substance of raw water also dec reased from 16 to 5. The total removal rate of CODMn andUV254were 45% ～ 72% and 60% ～ 80% following O3-GAC treatment. It reflected that this process had a good effective on removing unsaturation organic which absorb UV and toxic organic containing nitrogen. The results of Ames test indicated that raw water had a relatively strong mutagicity on TA 98. The O3-GAC process had a good ability in removing mutagen in water. The effluent water' s mutagicity is minus. The results of the study indicated that the effluent of the O3-GAC process was meet the demand of drinking water.
