<p>PURPOSE:To obtain the desulfurizer for a waste water treating acid forming tank having a high desulfurizing capacity by providing a waste water circulating passage, an exhaust passage and a return gas passage. CONSTITUTION:Waste water 1 is sprinkled from the top of the acid forming tank 3 used for decomposing the org. acid in the waste water and circulated through a waste water circulating passage 25, and the desulfurized gas at the outlet of the desulfurizer 30 is simultaneously introduced into the top of the tank 3 through a return gas passage 34. Consequently, the droplets 36 of the sprinkled waste water 1 are continuously brought into contact with a large amt. of the desulfurized gas C, gas-liq. contact is drastically improved, and the desulfurization efficiency is improved.</p> |
