Description

Technical Field

[0001] This utility model relates to the technical field of electroplating wastewater treatment, and in particular to a wastewater electrocoagulation device. Background Technology

[0002] Electrocoagulation is a water treatment process that uses metal hydroxides generated during electrolysis by a soluble metal anode to flocculate and remove pollutants from water. This technology can effectively remove colloidal and suspended pollutants from water.

[0003] In the current process of electrocoagulation treatment of wastewater, regular cleaning of the filter components is an essential step. However, in existing filtration structures, multiple filter plates need to be disassembled and cleaned individually, making the process extremely cumbersome. Therefore, in-situ rinsing has become a common cleaning method. However, for filtration structures integrating multiple densely arranged filter plates, it is difficult to thoroughly clean the inner filter plates during rinsing, resulting in poor cleaning effects and residual impurities on the filter plates, which in turn adversely affects the efficiency of subsequent wastewater treatment. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a wastewater electrocoagulation device, which is equipped with a secondary filter element that has a wastewater filtration function. Furthermore, through the coordinated action of a cleaning channel and multiple one-way valves, it can accurately rinse and clean a single filter plate unit, achieving thorough cleaning with high cleaning efficiency.

[0006] To achieve the above objectives, this utility model proposes a wastewater electrocoagulation device, comprising a first reaction chamber, a second reaction chamber, and a third reaction chamber.

A cleaning channel is provided through the barrier element; the mounting base communicates with the cleaning channel; multiple filter plate units are circumferentially distributed on the mounting base, with two filter plate units on each side abutting against the inner wall of the third reaction chamber; multiple one-way valves and multiple filter plate units are staggered on the mounting base; sedimentation chambers are respectively provided at the bottom of the first, second, and third reaction chambers, with discharge valves located on the lower side of each sedimentation chamber.

[0007] In addition, the wastewater electrocoagulation device proposed in the application may also have the following additional technical features:

[0008] Specifically, it also includes a collection channel, with the three discharge valves connected in sequence to the collection channel. The collection channel is inclined, with its high end located below the third reaction chamber and its low end located below the first reaction chamber.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] The wastewater electrocoagulation device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0023] like Figures 1-2 As shown, the wastewater electrocoagulation device of this utility model embodiment may include a first reaction chamber 101, a second reaction chamber 102 and a third reaction chamber 103.

[0024] The first reaction chamber 101 is equipped with a primary filter element 20. It should be noted that the primary filter element 20 described in this embodiment can be a filter screen or the like. The primary filter element 20 has the function of performing initial filtration of wastewater, which can effectively intercept large particulate impurities such as metal fragments and ore particles in the wastewater, preventing these impurities from adversely affecting the subsequent wastewater electrocoagulation and electrolysis treatment, and laying the foundation for the stable operation of the entire wastewater treatment process.

[0025] The second reaction chamber 102 is equipped with an electrocoagulation element 30. The two sides of the second reaction chamber 102 are connected to the first reaction chamber 101 and the third reaction chamber 103, respectively. The first reaction chamber 101 is provided with a first output pipe 1011 and a first input pipe 1012 on its upper and lower sides, respectively. The second reaction chamber 102 is provided with a second output pipe 1021 and a second input pipe 1022 on its upper and lower sides, respectively. The first output pipe 1011 is connected to the second input pipe 1022.

[0026] It should be noted that the electrocoagulation element 30 described in this embodiment has the function of electrocoagulating and electrolyzing the wastewater entering the second reaction chamber 102, which is existing technology and will not be described in detail here.

[0027] A secondary filter element 40 is installed in the third reaction chamber 103. The secondary filter element 40 may include a barrier element 401, a mounting base 402, multiple one-way valves 403, and filter plate units 404. The barrier element 401 is mounted on the top of the third reaction chamber 103, with its lower end inserted into the interior of the third reaction chamber 103 and connected to the arc-shaped mounting base 402. A cleaning channel 4011 is provided through the barrier element 401, and the mounting base 402 is connected to the cleaning channel 4011. Multiple filter plate units 404 are circumferentially distributed on the mounting base 402, and two filter plate units 404 located on both sides abut against the inner wall of the third reaction chamber 103. Multiple one-way valves 403 and multiple filter plate units 404 are staggered on the mounting base 402.

[0028] The plurality of filter plate units 404 described in this embodiment can sequentially perform secondary filtration treatment on the wastewater entering the discharge zone 1032 from the feed zone 1031.

[0029] The barrier 401 divides the third chamber into a feeding area 1031 and a discharging area 1032. A notch 1033 is provided on one side of the discharging area 1032. The left and right sides of the barrier 401 abut against the inner wall of the third reaction chamber 103. One end of the second output pipe 1021 extends into the feeding area 1031.

[0030] The bottom of the first reaction chamber 101, the second reaction chamber 102 and the third reaction chamber 103 are respectively provided with a settling chamber 50. A discharge valve 501 is provided on the lower side of the settling chamber 50. The three discharge valves 501 are connected to the collection channel 104 in sequence. The collection channel 104 is inclined, with its high end located below the third reaction chamber 103 and its low end located below the first reaction chamber 101.

[0031] Specifically, in the actual process of electrocoagulation treatment of wastewater (domestic sewage, industrial wastewater, agricultural wastewater, etc.), relevant personnel will first close three discharge valves, and then pressurize the wastewater, causing it to flow into the first reaction chamber 101 through the first output pipe 1011. As the wastewater level in the first reaction chamber 101 gradually rises, when it reaches a certain height, the wastewater will smoothly enter the second input pipe 1022 from the first output pipe 1011, and then flow into the second reaction chamber 102. In the first reaction chamber 101, the primary filter element 20 will perform its preliminary filtration function, intercepting some large particulate impurities in the wastewater, such as metal fragments and ore particles, thus achieving preliminary purification of the wastewater.

[0032] After entering the second reaction chamber 102, the electrocoagulation element 30 begins electrolytic treatment of the wastewater. The electrolyzed wastewater then enters the feed zone 1031 through the second output pipe 1021, flows sequentially through multiple filtration units, reaches the discharge zone 1032, and is finally discharged from the top of the discharge zone 1032. During this process, multiple filtration units perform deep filtration and impurity removal on the wastewater, improving its treatment quality.

[0033] During wastewater treatment, flocculated impurities generated inside the first, second, and third reaction chambers naturally enter their corresponding settling chambers. These impurities are then discharged through bottom discharge valves into collection channels for centralized collection and treatment, facilitating further disposal and preventing secondary pollution.

[0034] When multiple filter units need cleaning, staff first thoroughly drain the wastewater from the first, second, and third reaction chambers. Next, an external water source is connected to the cleaning channel, and cleaning water is injected into the channel. The cleaning water then flows precisely through multiple one-way valves, thoroughly rinsing the filter units. The rinse water then flows through a discharge valve at the bottom into a collection channel, where it is collected along with any flocculated impurities already present, ensuring the cleanliness and normal operation of the entire wastewater treatment system.

[0035] In summary, the wastewater electrocoagulation device of this utility model has a secondary filter element with wastewater filtration function. Furthermore, through the coordinated action of the cleaning channel and multiple one-way valves, it can accurately rinse and clean a single filter plate unit, achieving thorough cleaning with high cleaning efficiency.
