Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated sewage treatment device. Background Art

[0002] The electro-flocculation process is an efficient and clean sewage treatment technology. It mainly uses soluble anodes to release a large number of cations under the action of an external electric field. The cations are hydrolyzed to generate hydroxides and polynuclear hydroxyl complexes with strong adsorption effects, which flocculate the impurity ions in the wastewater and remove pollutants. As an efficient and clean sewage treatment technology, the electro-flocculation method combines the advantages of chemical flocculation and electrochemical methods for sewage treatment. It removes pollutants more thoroughly and can remove inorganic pollutants that cannot be treated by ordinary methods and difficult-to-degrade organic pollutants.

[0003] However, the density and structure of the flocs generated in the integrated equipment are usually uneven, resulting in different sedimentation rates. Some flocs are difficult to settle effectively because they are light or loose, and some of the generated flocs may have strong adhesion and are easy to adhere to the surface of the equipment or agglomerate into larger pieces. Therefore, the solid-liquid separation of flocs and water is a difficult problem in the electro-flocculation process.

[0004] The solid-liquid separation method of the integrated electro-flocculation equipment is usually to attach bubbles (mainly hydrogen) generated during the electrolysis process to the flocs to form a flotation effect, carry the pollutants to the water surface, and then scrape the floating flocs with a scraper or a tipping bucket; some flocs formed during the flocculation process can settle to the bottom of the pool under the action of gravity due to their high density, and then be pumped out by a pump. However, the natural sedimentation separation method takes a long time, has a low floc removal efficiency, and will carry a large amount of clean water in the process of removing the flocs, which is not conducive to further separation of the flocs in the later stage. Summary of the invention

[0005] The purpose of the present invention is to provide an integrated sewage treatment device to solve the problems raised in the above-mentioned prior art.

[0006] Provided is an integrated sewage treatment device, comprising:

[0007] a water inlet area, which includes a water inlet pipe;

[0008] A treatment area, comprising a floating pond at the bottom and a gas collecting chamber at the top, wherein one end of the treatment area is connected to the water inlet area through a water inlet pipe and the other end is provided with a water outlet, and a plurality of electrode assemblies are arranged in the floating pond along the length direction;

[0009] A filter plate assembly, comprising a filter plate, a first guide vane and a second guide vane, wherein the filter plate is arranged at one end of the floating pond close to the water outlet, the filter plate is an arc-shaped plate with a concave portion facing the water inlet area and the top of the plate body extending out of the liquid surface of the floating pond, the first guide vane is arranged at the concave portion of the filter plate and close to the top of the floating pond, and the second guide vane is arranged at the convex portion of the filter plate and close to the bottom of the floating pond;

[0010] The slag removal area is arranged between the water inlet area and the treatment area.

[0011] As a further embodiment of the present invention: the slag removal area includes a first baffle, which is arranged vertically between the slag removal area and the floating pond, the water inlet pipe passes through the first baffle and is connected to the floating pond, and a through groove for connecting the floating pond and the slag removal area is provided at the bottom of the first baffle. After the sewage enters the floating pond through the water inlet pipe, the first baffle can prevent the untreated sewage from directly entering the slag removal area, but needs to be processed by the electrode assembly and the filter plate in sequence before entering the slag removal area from the through groove for slag discharge.

[0012] As a further embodiment of the present invention: the deslagging area further comprises a second partition fixedly connected to the first partition, the second partition extending horizontally in the direction of the filter plate and being located between the plurality of electrode assemblies and the through slots. The second partition enhances the isolation effect between the processing area and the deslagging area and enhances the path shaping effect of the water flow.

[0013] As a further embodiment of the present invention: the slag removal area further includes a conveying guide rail, a plurality of slag removal plates and a material receiving trough, wherein the plurality of slag removal plates are driven to circulate through the conveying guide rail, and the slag removal plates are used to dump the slag material into the material receiving trough. The plurality of slag removal plates travel along a predetermined route of the conveying guide rail, and in the process of being lifted from the sewage, they take away the scum on the surface of the pool water, and dump the scum into the material receiving trough when passing through the material receiving trough, thereby removing the scum.

[0014] As a further embodiment of the present invention: the conveying guide rail includes a material receiving guide rail and a turning guide rail, and the turning guide rail is used to tilt the posture of the slag removal plate so that the slag material is dumped into the material receiving trough. When the slag removal plate passes through the turning guide rail, it tilts under the restriction of the guide rail, and the receiving surface of the slag removal plate faces the material receiving trough, so that the floating slag automatically slides into the material receiving trough by overcoming the friction force through its own gravity.

[0015] As a further embodiment of the present invention: the flip guide includes two arc-shaped extension sections and a straight transition section, the two arc-shaped extension sections are respectively connected to the two ends of the material receiving guide, and the two ends of the straight transition section are respectively connected to the two arc-shaped extension sections. The arc-shaped extension section is used to make the slag removal plate leave the range of the slag removal area, enter the area range of the material receiving trough, and adjust the posture of the slag removal plate so that the receiving surface is inclined toward the material receiving trough. The straight transition section is used to increase the maintenance time of the slag removal plate in the inclined posture, giving the floating slag enough time to leave the slag removal plate.

[0016] As a further embodiment of the present invention: when the slag removal plate moves on the conveying guide rail, a filter screen is provided on the side of the slag removal plate away from the receiving trough, and the receiving surface of the slag removal plate forms a slope that gradually decreases toward the filter screen. When the slag removal plate rises and takes away the floating scum, the water flow will flow toward the filter screen and filter out under the action of the slope, thereby enhancing the effect of solid-liquid separation. The filter screen can prevent the floating scum from being brought back into the sewage by the water flow.

[0017] As a further embodiment of the present invention: the end of the first guide vane is provided with a brush body capable of contacting the filter plate. When the brush bodies rotate, they continuously contact the filter plate and sweep away the flocs adhering to the surface of the filter plate to prevent the flocs from clogging the filter holes of the filter plate.

[0018] As a further embodiment of the present invention: the portion of the filter plate extending out of the liquid surface extends outward to form a vibrating plate, and a vibration module is abutted on the vibrating plate. The vibration template can generate kinetic energy to vibrate the vibrating plate, and the vibrating plate then transmits the vibration to the filter plate, so that the flocs on the surface of the filter plate that are difficult to remove are separated.

[0019] As a further embodiment of the present invention: an exhaust system is provided on the top of the gas collecting chamber. Hydrogen is generated after the electrode assembly interacts with the floating pond. The hydrogen is separated from the floating pond and gathered in the gas collecting chamber, and the hydrogen can be extracted by the exhaust system.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] When the first guide vane and the second guide vane rotate, flowing water can be formed in the floating pool. Part of the water flows through the filter plate to filter the flocs and form clear water to be discharged from the outlet. Part of the water flows, driven by the first guide vane and the second guide vane, carries the flocs into the slag removal area for slag removal to achieve solid-liquid separation. While the first guide vane rotates, it can also scrape off the flocs adhering to the surface of the filter plate to prevent the filter plate from being blocked and affecting the filtering effect.

DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. Based on the embodiments provided in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0030] Obviously, the drawings described below are only some examples or embodiments of the present application. For ordinary technicians in this field, the present application can also be applied to other similar scenarios based on these drawings without creative work. In addition, it can also be understood that although the efforts made in this development process may be complicated and lengthy, for ordinary technicians in this field related to the content disclosed in this application, some changes in design, manufacturing or production based on the technical content disclosed in this application are just conventional technical means, and should not be understood as insufficient content disclosed in this application.

[0031] However, unnecessary detailed descriptions may be omitted. For example, detailed descriptions of well-known matters and repeated descriptions of substantially the same structures may be omitted. This is to avoid the following description from becoming unnecessarily lengthy and to facilitate understanding by those skilled in the art. In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present application and are not intended to limit the subject matter described in the claims.

[0032] See also Figure 1-2 As shown, the integrated sewage treatment equipment in the embodiment of the present invention includes an inlet area 1, a treatment area 2, a filter plate assembly 3 and a slag removal area 4. The inlet area 1 includes an inlet pipe 11. The treatment area 2 includes a floating pond 21 at the bottom and a gas collecting chamber 22 at the top. One end of the treatment area 2 is connected to the inlet area 1 through the inlet pipe 11 and the other end is provided with an outlet 23. A plurality of electrode assemblies 24 are provided in the floating pond 21 along the length direction. The filter plate assembly 3 includes a filter plate 31, a first guide vane 32 and a second guide vane 33. The filter plate 31 is arranged at one end of the floating pond 21 near the outlet 23. The filter plate 31 is an arc-shaped plate with a concave portion facing the inlet area 1 and the top of the plate body extends out of the liquid surface of the floating pond 21. The first guide vane 32 is arranged at the concave portion of the filter plate 31 and near the top of the floating pond 21. The second guide vane 33 is arranged at the convex portion of the filter plate 31 and near the bottom of the floating pond 21. The slag removal area 4 is arranged between the water inlet area 1 and the treatment area 2 .

[0033] After the sewage enters the water inlet area 1, it enters the floating pond 21 of the treatment area 2 through the water inlet pipe 11. The impurities in the sewage are processed by a number of electrode assemblies 24 to form a flocculent state. The first guide vane 32 rotates to drive the sewage with flocs to move toward the filter plate 31, and separates the clean water from the flocs under the filtration of the filter plate 31, and the filtered clean water is discharged from the water outlet 23. The first guide vane 32 also guides the water flow to the lower part of the filter plate 31. The second guide vane 33 is used to change the direction of the water flow flowing to the bottom of the floating pond after rotation, and guides the water flow along the bottom of the floating pond toward the slag removal area 4, and the flocs are finally discharged in the slag removal area 4. The integrated equipment of the present application can automatically discharge the flocs while continuously outputting the filtered clean water. The flocs will not accumulate in the treatment area 2, but will be adsorbed on the motor assembly 24 and the surface of the filter plate 31, thereby realizing automatic treatment of sewage and solid-liquid separation.

[0034] The slag removal area 4 is isolated from the floating pond 21 by the first partition 41, which prevents the sewage from being directly introduced into the slag removal area 4 after being connected to the water inlet pipe 11 without being treated by the electrode assembly 24, thereby occupying the space of the sewage that has been treated by the electrode assembly 24, causing chaotic turbulence in the floating pond, and reducing the efficiency of the integrated equipment in treating sewage. Under the guidance of the first guide vane 32 and the second guide vane 33, the water flows from the bottom of the floating pond to the through groove 411, and enters the slag removal area 4 from the through groove 411.

[0035] In one embodiment, the top of the first baffle 41 extends out of the liquid surface of the floating pool 21, and a reflux port is provided at a position of the first baffle 41 above the through groove 411, so that the sewage after slag discharge can be returned to the treatment area 2 through the reflux port for secondary treatment, thereby forming a circulating flow in the entire water pool.

[0036] In one embodiment, the top of the first baffle 41 is lower than the liquid level of the floating pool 21. The sewage after slag removal returns to the treatment area 2 through the top of the first baffle 41 for secondary treatment, and the entire pool forms a circulating flow. Since the water level in this part of the return area is relatively high, driven by the overall circulating water flow, the sewage entering the floating pool from the water inlet pipe 11 will not enter the slag removal area 4 from the top.

[0037] Furthermore, the slag removal area 4 also includes a second baffle 42 fixedly connected to the first baffle 41. The fixed end fixed node of the second baffle 42 is located between the motor assembly 24 and the through slot 411. When the second baffle 42 extends toward the filter plate 31, the floating pond 21 is divided into two parts, an upper and a lower part, as a whole. The water flow in the upper part passes through a number of electrode assemblies 24 in sequence and flows toward the filter plate 31. The water flow in the lower part moves toward the through slot 411 as a whole under the drive of the second guide vane 33. Therefore, the second baffle 42 eliminates the interaction between the upper and lower water flows, thereby enhancing the laminar flow effect of the upper and lower parts of the floating pond 21. A third guide vane can also be provided in the lower water flow part of the second baffle 42 near one end of the through slot. The third guide vane can further enhance the driving force of the lower water flow and improve the layered forming effect of the floating pond.

[0038] The slag removal area 4 is used to discharge the flocs and scum entering from the through slot 411. The slag removal components of the slag removal area 4 specifically include a conveying guide rail 43, a plurality of slag removal plates 44 and a material receiving trough 45. The conveying guide rail 43 drives a plurality of slag removal plates 44 to move along a predetermined track through a sprocket mechanism on both sides or in the middle. The slag removal plates 44 collect and scoop up the scum during movement in the water pool, and dump the scum into the material receiving trough 45 outside the water pool. After completing a slag removal task, the slag removal plates 44 return to the water pool under the drive of the conveying guide rail 43 to perform the next round of slag removal operation, forming a cycle of work.

[0039] See also Figure 1 , Figure 3 and Figure 4 As shown, specifically, the conveying guide rail 43 includes a material receiving guide rail 431 and a flip guide rail 432. The material receiving guide rail 431 is mainly located inside the water pool. The slag removal plate 44 on this part of the guide rail collects scum during the travel and separates the scum from the water pool. The flip guide rail 432 changes the travel direction of the slag removal plate 44 by changing the extension direction of the track, so that the slag removal plate 44 is separated from the distribution range of the water pool and enters the distribution range of the material receiving trough 45. The flip guide rail 432 also changes the posture of the slag removal plate 44 by twisting the track. When the slag removal plate 44 is below the liquid level of the water pool, the receiving surface of the slag removal plate 44 is facing the opposite direction of the travel to collect the scum in the water pool. When the slag removal plate 44 is separated from the water pool, the receiving surface is turned to the direction of the material receiving trough 45 under the action of the flip guide rail 432, and a certain inclination angle is made so that the slag can overcome the friction between the receiving surface and the receiving surface through its own gravity and fall into the material receiving trough 45.

[0040] Further, the flip guide rail 432 includes two arc-shaped extension sections 4321 and a straight transition section 4322. The arc-shaped extension section 4321 starts from the pool area of ​​the slag removal area 4, extends to the outer area of ​​the pool through the arc-shaped guide rail, and enters the area range of the material receiving trough 45. The guide rail of the arc-shaped extension section 4321 changes the travel direction and posture of the slag removal plate 44 through structural turning and structural twisting. In the embodiment of the present application, the material receiving trough 45 is arranged at the end of the slag removal area 4 away from the floating pond 21. When the slag removal plate 44 enters the arc-shaped extension section 4321, the receiving surface faces upward, and when leaving the arc-shaped extension section 4321, the receiving surface rotates 90° and faces the side different from the floating pond 21, and the slag can automatically slide into the material receiving trough 45. After leaving the arc-shaped extension section 4321, the straight transition section 4322 can keep the posture of the slag removal plate 44 unchanged for a period of time, giving the floating slag sufficient time to escape. The arc-shaped extension section 4321 at the other end returns the slag removal plate 44 from the material receiving trough 45 area to the water pool area.

[0041] For further information, see Figure 4 and Figure 5 As shown, when the slag removal plate 44 moves on the conveying pipe guide rail 43, a filter screen 441 is provided on the side of the slag removal plate 44 away from the material receiving trough 45, and the receiving surface of the slag removal plate 44 forms a slope that gradually decreases toward the side of the filter screen 441. The slope of the slope is determined by the slag material being able to remain stationary by friction, and the water mixed with the slag material being able to flow from the slope to the filter screen 441 and be discharged through the filter screen 441. The slope of the slope may specifically be 5° to 15°. The slope of the slope should not be too large to prevent the slag material from being difficult to slide off the surface of the slag removal plate 44 due to the slope after the slag removal plate 44 is tilted by the arc-shaped extension section 4321. The slope of the slope should not be too small, as a too small slope makes it difficult for water to flow out of the slope surface.

[0042] See also Figure 1 and Figure 2 As shown, the end of the first guide vane 32 is provided with a brush body 321 that can contact the filter plate 31. When the brush body 321 rotates, it continuously contacts the filter plate 31 and sweeps away the flocs adhered to the surface of the filter plate 31 to prevent the flocs from clogging the filter holes of the filter plate 31. The brush body 321 can be a brush or rubber, so that it will not cause interference and excessive obstruction when contacting the filter plate 31.

[0043] See also Figure 1 and Figure 2As shown, the portion of the filter plate 31 extending out of the liquid surface extends outward to form a vibrating plate 311, and a vibration module 312 is abutted on the vibrating plate 311. The vibration module 312 can be a vibration motor, which makes the vibrating plate 311 produce a vibration effect. The vibration motor can be connected to the vibrating plate 311 through a flexible shaft, so that the vibration motor is away from the floating pond to prevent sewage from splashing onto the vibration motor. The vibration module 312 can also be composed of an eccentrically rotating protrusion, which is eccentrically connected to the output shaft of the actuator to produce eccentric rotation, and continuously hits the vibrating plate 311 to make the vibrating plate 311 produce a vibration effect.

[0044] See also Figure 1 As shown, an exhaust system 5 is provided at the top of the gas collecting chamber 22. The exhaust system may specifically consist of a ventilation pipe and an exhaust fan blade, which is driven to rotate by an actuator to fan out the hydrogen in the gas collecting chamber 22 from the ventilation pipe. The exhaust system may also consist of a ventilation pipe and an exhaust fan, which directly extracts the hydrogen in the ventilation pipe.

[0045] It should be noted that the present application is not limited to the above-mentioned embodiments. The above-mentioned embodiments are only examples, and the embodiments having the same structure as the technical idea and exerting the same effect within the scope of the technical solution of the present application are all included in the technical scope of the present application. In addition, without departing from the scope of the main purpose of the present application, various modifications that can be thought of by those skilled in the art to the embodiments and other methods of combining some of the constituent elements in the embodiments are also included in the scope of the present application.
