Description

Technical Field

[0001] This utility model relates to the technical field of ultraviolet light activation treatment of landfill leachate, and in particular to a high-efficiency ultraviolet light activation treatment device for landfill leachate. Background Technology

[0002] Filtrate is a liquid with a high concentration of organic or inorganic components that is produced during the dumping and landfilling of waste, under the combined effects of precipitation and groundwater seepage.

[0003] In existing waste-to-energy plants, the waste storage ponds are basically flat-bottomed deep pits with seepage trenches to collect leachate. However, the leachate collection effect is far from ideal. The leachate channels in the waste ponds contain substances such as acidic gases and explosive methane gases. Leachate is a special type of organic wastewater with complex water quality and a strong odor that can cause nausea, dizziness, and other symptoms. The method of manually clearing the leachate gratings poses a huge safety and health hazard to the personnel involved in the clearing process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 The present invention provides the following technical solution:

[0030] A high-efficiency ultraviolet light activation treatment device for landfill leachate includes a filter assembly 1, an activation assembly 2, a treatment tank 3, and an activation tank 4. The filter assembly 1 is disposed inside the treatment tank 3, the activation assembly 2 is disposed inside the activation tank 4, and the activation tank 4 is fixedly connected to the rear side of the treatment tank 3.

[0031] The filter assembly 1 includes a first lifting plate 101, a connecting plate 102, a filter box 103, a first filter plate 104, a second filter plate 105, a guide plate 106, and a flow guide box 107. The first lifting plate 101 is fixedly connected to the top of the connecting plate 102, and the connecting plate 102 is fixedly connected to the top of the second filter plate 105. The filter box 103 and the second filter plate 105 are both snapped into the inside of the processing box 3. The first filter plate 104 is fixedly connected to both sides inside the processing box 3. The guide plate 106 is fixedly connected to the bottom inside the flow guide box 107, and the flow guide box 107 is fixedly connected to the bottom of the processing box 3.

[0032] In this embodiment: The filter assembly 1 effectively filters impurities and floating matter in the landfill leachate. The activation assembly 2 agitates the leachate during ultraviolet light activation treatment, thus addressing the issue of the leachate's dark color hindering ultraviolet light penetration. The first lifting plate 101, used in conjunction with the connecting plate 102, allows the second filter plate 105 to be removed from the processing tank 3 for cleaning. With the filter box 103, which is made entirely of filter plates, the first filter plate 104, used in conjunction with the filter box 103, can filter impurities and floating matter in the landfill leachate. The second filter plate 105 can achieve secondary filtration. The guide plate 106, used in conjunction with the guide box 107, can transport the filtered landfill leachate into the activation box 4.

[0033] Specifically, such as Figure 4 As shown, the activation component 2 includes a support frame 201, which is fixedly connected to the top of the activation box 4. An electric telescopic plate 202 is fixedly connected to the rear side of the support frame 201, and a baffle 203 is fixedly connected to the bottom of the electric telescopic plate 202.

[0034] Specifically, such as Figure 4 As shown, the two sides inside the activation box 4 are fixedly connected to the connecting shell 204, and the inner wall of the connecting shell 204 is fixedly connected to the ultraviolet light emitter 205.

[0035] Specifically, such as Figure 4 As shown, a rotating rod 206 is rotatably connected inside the activation box 4. A transmission rod 207 is fixedly connected to the right side of the rotating rod 206. An agitator 208 is fixedly connected to the surface of the rotating rod 206. A motor 209 is fixedly connected to the right side of the transmission rod 207.

[0036] In this embodiment: the support frame 201 connects and fixes the electric telescopic plate 202, connects and adjusts the baffle 203, and prevents leachate from entering the activation tank 4. The connecting shell 204 connects and fixes the ultraviolet emitter 205, and emits ultraviolet light... The transmitter 205 is an existing ultraviolet light device that can emit ultraviolet light to activate landfill leachate. The rotating rod 206 is connected to the stirring plate 208, so that the rotating rod 206 can work with the stirring plate 208 to agitate the landfill leachate in the activation box 4. The transmission rod 207 is connected to the rotating rod 206. The motor 209 provides rotational power to the transmission rod 207.

[0037] Specifically, such as Figure 3 As shown, a second lifting plate 5 is fixedly connected to the top of the filter box 103, a guide plate 6 is fixedly connected to the bottom inside the filter box 103, and sliding grooves 7 are provided on the front and rear sides of the filter box 103.

[0038] Specifically, such as Figure 6 As shown, a discharge pipe 8 is fixedly connected to the bottom of the activation box 4, and a valve 9 is fixedly connected to the surface of the discharge pipe 8.

[0039] In this embodiment: the second lifting plate 5 facilitates the removal of the filter box 103 from the treatment box 3 for cleaning; the guide plate 6 guides the leachate; the chute 7 limits the position of the filter box 103; the discharge pipe 8 discharges the leachate after ultraviolet light activation treatment; and the valve 9 controls the opening and closing of the discharge pipe 8.

[0040] Specifically, such as Figure 6 As shown, a rotating hole 10 is provided on the right side of the activation box 4, and the inner wall of the rotating hole 10 is rotatably connected to the surface of the transmission rod 207.

[0041] Specifically, such as Figure 6 As shown, transparent protective glass 11 is fixedly connected to both sides inside the activation box 4, and the top of the transparent protective glass 11 is fixedly connected to the bottom of the connecting shell 204.

[0042] In this embodiment: by setting the rotating hole 10, the rotating hole 10 can achieve the effect of limiting the rotational connection of the transmission rod 207. By setting the transparent protective glass 11, the transparent protective glass 11 is an existing glass that will not block ultraviolet light, and at the same time, it can also prevent the leachate from falling onto the ultraviolet emitter 205 when the leachate is turned over.

[0043] Specifically, such as Figure 5 As shown, a slide plate 12 is fixedly connected to both the left side of the first filter plate 104 and the left side inside the processing box 3, and the surface of the slide plate 12 is slidably connected to the inner wall of the slide groove 7.

[0044] Specifically, such as Figure 5 As shown, the top of the processing box 3 is provided with a slot 13, and the inner wall of the slot 13 is engaged with the bottom of the first lifting plate 101.

[0045] In this embodiment: the sliding plate 12 allows for sliding connection with the slide groove 7, and the locking slot 13 allows for locking and positioning of the first lifting plate 101.

[0046] Working principle: First, the leachate is introduced into the filter box 103. Then, the filter box 103 filters out impurities and floating matter in the leachate. After filtration, the leachate flows through the filter box 103 and the first filter plate 104 into the rear of the filter box 103, and then through the second filter plate 105 for secondary filtration. After further filtration, the leachate flows through the second filter plate 105 into the guide box 107. Guided by the guide plate 106 inside the guide box 107, it enters the activation box 4 through the slot on the rear side of the guide box 107 and the slot on the front side of the activation box 4. Then, when the leachate in the activation box 4 accumulates to a certain amount... Then, the electric telescopic plate 202 is opened to adjust the baffle 203, thereby sealing the slot on the front side of the activation box 4. Then, the motor 209 is turned on, causing the transmission rod 207 and the rotating rod 206 to rotate. This causes the rotating rod 206 to rotate the stirring plate 208, thereby agitating the leachate inside the activation box 4. Then, the ultraviolet light emitter 205 is turned on, causing the ultraviolet light emitter to emit ultraviolet light that can activate the leachate. Combined with the agitation of the leachate inside the activation box 4, this solves the problem that the ultraviolet light cannot penetrate the leachate to activate it due to its dark color.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
