Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater filtration and treatment device for desulfurization of industrial boilers. Background Technology

[0002] Wastewater generated during the desulfurization process of industrial boilers contains large amounts of acidic substances (such as sulfuric acid and sulfurous acid), suspended solids, heavy metal ions (such as mercury and lead), and other corrosive components. Direct discharge of this type of wastewater will not only cause serious environmental pollution but also significantly damage the filter materials in traditional filtration devices, thereby affecting the filtration effect and the service life of the equipment.

[0003] Currently, common filter materials such as quartz sand, activated carbon, and polymer membrane materials are in long-term contact with desulfurization wastewater. Existing filtration devices are often not specially designed for the strong corrosiveness and high pollution characteristics of desulfurization wastewater. The corrosion resistance of the filter materials is insufficient, and they are prone to damage and failure, which in turn affects the stability and compliance rate of wastewater treatment. Utility Model Content

[0006] Preferably, both of the support components include a support member, a threaded member, and a perforated sliding member. The perforated sliding member passes through the top of the support member and can slide on the support member. Both the support member and the perforated sliding member have multiple threaded holes, and the threaded member is threadedly connected to the support member and the perforated sliding member, respectively.

[0007] Preferably, the acid-base balance mechanism further includes a first connecting pipe, a first water pump, a second water pump, and a second connecting pipe. The first water pump is disposed between the first connecting pipes, and the first connecting pipe is detachably connected to and communicates with the first water pump. The second water pump is disposed between the second connecting pipes, and the second connecting pipe is detachably connected to and communicates with the second water pump.

[0008] Preferably, the filtration mechanism includes a filter box, a water outlet pipe, and four filter media. All four filter media are disposed inside the filter box. The water outlet pipe passes through the right side of the filter box and is detachably connected to and communicates with the filter box.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, after treatment by the acid-base balance mechanism, the strong acid, high concentration of sulfides and heavy metal ions in the sewage have been greatly reduced. The filter in the filter box does not need to directly contact the highly corrosive components, and only needs to treat trace amounts of residual pollutants, thereby reducing the rate of chemical corrosion and mechanical wear of the material.

[0014] 2. In this utility model, the second detection sensor in the detection tank performs a second detection on the wastewater after the initial treatment. If the sulfide residue exceeds the standard, a high-molecular sulfide capture agent is added through the second feed pipe to further reduce the sulfide concentration, ensuring that the corrosiveness of the wastewater entering the filtration mechanism is significantly reduced, and preventing the filter agent from failing due to long-term contact with high concentrations of sulfides.
