Device and method for increasing yield of gypsum in desulfurization wastewater
The invention relates to the technical field of sewage treatment, and discloses a device and a method for increasing the yield of gypsum in desulfurization wastewater. The device comprises a separation unit, a conditioning unit and a dehydration unit. The method comprises the following steps: (1) carrying out separation treatment on desulfurized thick slurry to obtain desulfurized wastewater and gypsum sludge I; (2) a conditioning agent, recovered gypsum and the desulfurization wastewater are subjected to a conditioning reaction, and gypsum sludge II is obtained; and (3) carrying out dehydration treatment on the gypsum sludge I and the gypsum sludge II to obtain recycled gypsum. The device and the method for increasing the yield of the gypsum in the desulfurization wastewater, provided by the invention, have the characteristics of high gypsum yield, simple process and low treatment cost.
本发明涉及污水处理技术领域，公开了一种提高脱硫废水中石膏产量的装置和方法。该装置包括分离单元、调质单元、脱水单元。该方法包括：(1)将脱硫浓浆进行分离处理，得到脱硫废水和石膏污泥I；(2)将调节剂、回收石膏、所述脱硫废水进行调质反应，得到石膏污泥II；(3)将所述石膏污泥I和所述石膏污泥II进行脱水处理，得到回收石膏。本发明提供的提高脱硫废水中石膏产量的装置和方法具有石膏产量高、工艺简单、处理成本低的特点。
