Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a desulfurization wastewater treatment device for a thermal power plant. Background Art

[0002] Desulfurization wastewater is mainly the discharge water from the absorption tower during the wet desulfurization of boiler flue gas (limestone and gypsum methods). The impurities contained in the wastewater mainly include suspended solids, supersaturated sulfites, sulfates and heavy metals. Direct discharge will cause serious pollution to the environment. Therefore, it needs to be treated to meet the standards before discharge. The main treatment goal of desulfurization wastewater is to remove sulfides in the water. The most commonly used method is chemical precipitation. By adding an appropriate amount of precipitant to the wastewater, the sulfide is converted into a water-insoluble sulfide precipitate, and the sulfide removal is completed by solid-liquid separation.

[0003] In the prior art, during the desulfurization process, sediment adheres to the inside of the box. After the supernatant is extracted, the staff needs to manually scrape off the sediment attached to the inner wall of the treatment device. During this process, the device cannot perform wastewater treatment work again, which not only requires a lot of labor but also has low work efficiency. In the prior art, the precipitant is not evenly added, and the contact between the desulfurization wastewater and the precipitant in various parts of the device is not uniform, resulting in uneven sulfide precipitation in the desulfurization wastewater in various parts and incomplete treatment of the desulfurization wastewater.
