Abstract
The invention discloses a waste gas treatment system which comprises a spray tower, an activated carbon adsorption box connected with the output end of the top of the spray tower and a catalytic oxidation tower connected with the output end of the activated carbon adsorption box. The waste gas treatment system comprises the following steps that (A) waste gas is pumped into a spray tower through a fan, a PH regulator is added into the spray tower to keep a PH valve in the spray tower to be 6-9; (B) the waste gas subjected to the step (A) flows into an activated carbon adsorption box from the top of the spray tower to adsorb peculiar smell in the waste gas; (C) the waste gas subjected to the step (B) flows into a catalytic oxidation tower to remove OH free radicals through reaction and enables clean air to be discharged out of the catalytic oxidation tower and discharge clean water from the bottom of the catalytic oxidation tower, and waste gas treatment is completed. When the waste gas treatment system is used, the dosage is greatly decreased, accordingly secondary pollution is reduced, the energy consumption and cost are effectively reduced, meanwhile absolutely clean air and clean water are discharged out of the system, and the waste gas treatment system is good in applicability and practicability.
