Abstract

The invention relates to the technical field of desulfurization wastewater treatment, in particular to a desulfurization wastewater pretreatment reaction device which comprises an adjusting tank, a sludge mixing tank and a reaction sedimentation tank, the reaction sedimentation tank is provided with a mixed reaction tank, a flocculation tank, inclined tube areas, a sedimentation area and a clear water area, the mixed reaction tank and the flocculation tank are suspended in the reaction sedimentation tank through a fixing bracket, wastewater in the mixed reaction tank can overflow into the flocculation tank through a flow guide region, inclined tube areas are symmetrically arranged on the inner wall of the reaction sedimentation tank in a suspended manner along the flowing direction of wastewater, a space between the bottom of the inclined tube area and the bottom wall of the reaction sedimentation tank and a space between an extension surface parallel to the flowing direction of the wastewater and the bottom wall of the reaction sedimentation tank are the sedimentation area, the clear water area is arranged on the outer side wall of the reaction sedimentation tank, the adjusting tank, the sludge mixing tank and the mixed reaction tank are sequentially communicated, and the sedimentation area is communicated with the sludge mixing tank.

Description

Technical field [0001] The invention relates to the technical field of desulfurization wastewater treatment, in particular to a desulfurization wastewater pretreatment reaction device. Background technique [0002] my country is the world’s largest producer and consumer of coal. The proportion of coal in China’s energy structure is as high as 76.2%. 2 90% comes from coal. In recent years, although my country has adopted a pollutant discharge fee policy, the annual SO 2 The amount of emissions is still very large, causing huge damage to my country’s crops, forests, and human health. It has also become an important factor restricting the sustainable development of the economy and society. 2 Emission control is imperative. [0003] The limestone-gypsum wet desulfurization process is currently the only large-scale commercial application of desulfurization, and it is also the control of SO 2 The main technical means of pollution. However, during the operation of the desulfurization sys...
