    Abstract: This desulfurization device is for desulfurizing a discharge gas which contains sulfur oxides and which was discharged from a device for sulfuric acid production that includes a concentrated-sulfuric-acid production step in which sulfur trioxide gas obtained by oxidizing sulfur dioxide gas is absorbed in an aqueous sulfuric acid solution while supplying water thereto to thereby produce sulfuric acid having a concentration as high as 90 wt % or more but less than 99 wt %, the desulfurization device comprising: a desulfurization tower in which the sulfur oxides are removed from the discharge gas and, simultaneously therewith, dilute sulfuric acid is formed from the sulfur oxides; and a dilute sulfuric acid mixer which, in the concentrated-sulfuric-acid production step, mixes the dilute sulfuric acid with the aqueous sulfuric acid solution.

    Abstract: Disclosed herein is a water treatment process for efficiently removing oils from oil-containing water.The water treatment process is a method for treating oil-containing water, comprising the steps of: preparing an oil-adsorbing material that is made of a lipophilic resin such as a pyridine resin and that has many pores in its surface and bears hydrophilic groups on an inner surface of the pores; and bringing oil-containing water into contact with the surface of the oil-adsorbing material. The step of preparing an oil-adsorbing material includes the step of converting some of hydrophobic groups, such as nitrogen-containing aromatic rings, on the inner surface of the pores to hydrophilic groups such as quaternized amine or sulfonic acid.

    Abstract translation: 本文公开了一种用于从含油水中有效地除去油的水处理方法。 水处理方法是一种处理含油水的方法，其特征在于，包括以下步骤：制备由亲水性树脂如吡啶树脂制成的油吸附材料，并且在其表面具有许多孔并且具有亲水基团 孔的内表面; 并使含油水与吸油材料的表面接触。 制备油吸附材料的步骤包括将孔内表面上的一些疏水基团如含氮芳环转化为亲水基团如季胺或磺酸的步骤。
