DETAILED DESCRIPTION

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a denitration catalyst cleaning wastewater treatment device, such as Figure 1-5 As shown, the denitration catalyst cleaning wastewater treatment device comprises: a base frame 1, on which a first filter box 2, a second filter box 3 and a disinfection box 4 for treating denitration catalyst cleaning wastewater are arranged, the first filter box 2 is connected to the second filter box 3 and the disinfection box 4 in sequence through corresponding water pipes 5, and the corresponding water pipes 5 are all provided with solenoid valves, and a wastewater injection port is arranged on the top of the first filter box 2; a grid plate 6, which is fixed in the first filter box 2 and is used for preliminary filtering of wastewater impurities; a removable filter basket 7 and a plurality of filter plates 8 The filter basket 7 and multiple filter plates 8 are all arranged in the second filter box 3, which are used to further filter wastewater impurities; a box cover 9, which is arranged on the top of the disinfection box 4, and a number of sterilization lamps 10 are fixedly installed on the box cover 9, which are used to sterilize the water in the disinfection box 4; a stirring mechanism for stirring the water in the disinfection box 4, and the stirring mechanism is arranged on the box cover 9; a cleaning mechanism for cleaning the grid plate 6, and the cleaning mechanism is arranged on the first filter box 2; a debris discharge mechanism for discharging impurities, and the debris discharge mechanism is arranged on the first filter box 2.

[0023] It should be noted that physical precipitation is usually used to remove suspended matter and large particles in wastewater. However, for denitrification catalyst cleaning wastewater, this method has limited effect. Because these wastewaters contain not only suspended matter, but also a large amount of soluble heavy metal ions and difficult-to-degrade organic matter. Physical precipitation cannot effectively remove these soluble pollutants; chemical precipitation removes the pollutants in the wastewater by adding chemical agents to the wastewater, so that the pollutants react with the agents to form precipitates. Chemical precipitation is a commonly used treatment method for heavy metal ions in denitrification catalyst cleaning wastewater. However, this method has some limitations: in order to achieve the ideal removal effect, a large amount of chemical agents are often required, resulting in increased treatment costs; the generated precipitates will form sludge, which requires further treatment or disposal, increasing the difficulty and cost of treatment; chemical precipitation has a poor removal effect on difficult-to-degrade organic matter and needs to be combined with other treatment methods; biological treatment removes organic pollutants in wastewater by utilizing the metabolism of microorganisms. However, the difficult-to-degrade organic matter in denitrification catalyst cleaning wastewater poses a challenge to the degradation ability of microorganisms. These refractory organic substances have complex structures and are difficult to be degraded by microorganisms, so the effect of biological treatment is limited.

[0030] In this embodiment, the introduction of the impurity discharge mechanism significantly improves the discharge efficiency of impurities in the first filter box 2. The slag discharge channel 22 is arranged on the first filter box 2, and is used to collect and temporarily store the larger particle impurities intercepted by the grid plate 6. This design ensures that the impurities can be effectively collected and discharged without affecting the normal filtering operation. The auger 23 is rotatably installed in the slag discharge channel 22, and one end of its shaft extends out of the slag discharge channel 22. The auger is a screw conveyor, and when it rotates, it can push the impurities in the slag discharge channel 22 outward along the spiral path.
