Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, and more specifically, to a desulfurization wastewater pre-sedimentation device. Background Art

[0002] Desulfurization is a critical environmental step in industrial production processes such as coal, petroleum, steel, and cement, effectively reducing atmospheric sulfur compound emissions. However, this process generates large quantities of sulfur-containing wastewater, which contains high concentrations of heavy metals, suspended solids, and hazardous substances. Direct discharge would have serious environmental and ecological impacts. Therefore, desulfurization wastewater must be effectively treated to ensure compliance with relevant environmental standards before it can be discharged. Currently, there are a large number of desulfurization wastewater treatment plants on the market. Despite their diverse variety and large number, these plants still face challenges and problems in their actual operation. One prominent issue is the generation of sludge in the treated wastewater. This sludge, formed when the sulfur wastewater is mixed with the flocculant, adheres to the surface of the filter plates and is difficult to remove. Over time, this sludge accumulates and clogs the filter plates, resulting in reduced desulfurization efficiency or even complete failure. Filter plate clogging not only affects desulfurization performance but also increases equipment maintenance costs, as the filter plates require regular cleaning and replacement. In addition, filter plate blockage may also cause a series of other problems, such as equipment failure, operation interruption, etc., which will adversely affect the production process.
