Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to an intelligent zoning sewage treatment pool. Background Art

[0002] The SBR sewage treatment process is a commonly used sewage treatment process. By continuously aerating the sewage, the growth environment of microorganisms in the sewage is changed, thereby accelerating the decomposition of organic matter, ammonia, nitrogen and other pollutants in the sewage by microorganisms. However, when the sewage in the sewage treatment pool meets the discharge requirements, the aeration pipe stops aeration and stands for a period of time. The sludge gradually settles to the bottom. At this time, the clear liquid on the upper layer needs to be discharged. Currently, water is taken from the surface of the water using a decanter to avoid disturbing the sludge in the lower layer.

[0003] However, in the process of aerating sewage, a large number of bubbles generated by aeration will carry some impurities such as oil and fiber and float on the water surface, gradually forming a layer of scum on the sewage surface, and some old sludge broken and deflocculated biological flocs are suspended in the water and are not easy to sink. When using a decanter to drain water, suspended impurities and some scum will be discharged with the water and affect the water quality of the effluent. If a filter is set at the water inlet of the decanter, the impurities will continue to adhere to the surface of the filter under the influence of the water flow, so that more impurities will accumulate on the surface of the filter after a period of filtration, which will seriously affect the smoothness of the clear liquid passing through the filter, resulting in a decrease in drainage speed and even possible clogging of the filter. Summary of the invention

[0004] In order to overcome the disadvantage that when the decanter of the existing sewage treatment pool is drained, suspended impurities and some scum will be discharged with the water and affect the water quality of the effluent; if a filter is set at the water inlet, the impurities will continue to adhere to the surface of the filter under the drive of the water flow, seriously affecting the smoothness of the clear liquid passing through the filter, the present invention provides an intelligent zoning treatment sewage pool.

[0005] The technical implementation scheme of the present invention is: an intelligent partitioned sewage treatment pool, including a sewage treatment pool, an electric guide rail, a connecting frame and a shell; a pre-storage area is set in the sewage treatment pool; a reaction zone is set in the sewage treatment pool, and an aeration pipeline is set at the bottom of the reaction zone; two electric guide rails are fixedly connected to the reaction zone; a connecting frame is slidably connected between the electric guide rails; a shell is fixedly connected to the connecting frame; a baffle, a second filter screen, a drainage branch pipe, a drainage pipe and a slag discharge pipe are also included; a water inlet is opened on the right side of the shell; a partition is fixedly connected in the shell; the right side of the shell A baffle is connected via an electric slider, and the baffle is sealed and slidably connected to the inner wall of the shell; a through opening is opened on the baffle, and a first filter is arranged on the lower side of the through opening; a second filter is rotatably connected to the left side of the baffle; the other side of the second filter is rotatably connected to the shell; a number of drainage branch pipes for drainage are connected to the shell, and the drainage branch pipes are made of deformable materials; all drainage branch pipes are commonly connected to a drainage pipe; a slag discharge pipe for discharging impurities is connected to the shell; the drainage branch pipe opening is located on the right side of the slag discharge pipe opening, and the partition is located between the drainage branch pipe opening and the slag discharge pipe opening.

[0006] In addition, it is particularly preferred that a capacitive liquid level sensor is provided on the right side of the baffle, the capacitive liquid level sensor is located on the upper side of the through opening, and a vertical groove for avoiding the up and down movement of the capacitive liquid level sensor is opened at a corresponding position on the shell.

[0007] In addition, it is particularly preferred that a scraper is further included; the scraper is fixedly connected to the right side of the shell, the scraper is located at the lower side of the water inlet, and the scraper is tightly attached to the first filter screen.

[0008] In addition, it is particularly preferred that two slide rails are arranged on the second filter screen; a scraper is slidably connected between the slide rails.

[0009] Furthermore, it is particularly preferred that the scraper is L-shaped.

[0010] In addition, it is particularly preferred that the scraper is made of high-density metal material.

[0011] In addition, it is particularly preferred that a first guiding slope is provided on the lower side of the interior of the shell and is inclined downward toward the slag discharge pipe opening; the first guiding slope is located on the left side of the partition.

[0012] Furthermore, it is particularly preferred that the housing bottom is provided with a second guide slope inclined from the lower left side toward the upper right side.

[0013] In addition, it is particularly preferred that the drainage branch pipe and the slag discharge pipe are both arranged to be inclined from the upper left side to the lower right side.

[0014] In addition, it is particularly preferred that it also includes an electric rotating shaft; the electric rotating shaft is connected to the shell through a fixed plate, the electric rotating shaft is located on the upper side of the slag discharge pipe mouth, and a plurality of cutting blades are fixedly connected to the lower side of the electric rotating shaft.

[0015] Beneficial effects: The present invention realizes that the water inlet is immersed in water, the clear liquid passes through the water inlet, the through port and the second filter screen in sequence, and is finally discharged through the drainage branch pipe and the drainage pipe. The second filter screen intercepts suspended impurities to ensure the quality of the clear liquid. The connecting frame and the shell move downward at a uniform speed to continuously take water from the surface layer of the water surface to avoid disturbing the lower layer of sludge. The suspended impurities in the clear liquid can be intercepted by the second filter screen to avoid the suspended impurities from mixing into the clear liquid and being discharged together, thereby affecting the water quality of the clear liquid. When the second filter is blocked and the drainage speed decreases, the downward movement speed of the shell remains unchanged, causing the water surface to move upward relative to the shell. When the water surface moves up to the point where the capacitive liquid level sensor is detected, it can be known that the port is completely submerged in water. When the second filter is blocked and the drainage speed decreases, the capacitive liquid level sensor detects the water level rise, controls the electric slider to drive the baffle to move up, aligns the first filter with the water inlet, tilts the second filter, and the scraper made of high-density material slides along the slide rail to scrape off suspended impurities to the first guide slope, and intercepts impurities through the first filter to ensure smooth drainage. Before draining, the baffle is first moved up to block the water inlet, the second filter screen is rotated to tilt toward the lower left side, the housing and its connected parts are moved down, the baffle is completely immersed in water, the water flow carries the scum over the baffle and falls onto the second filter screen, and then the scum is intercepted by the second filter screen, most of the clear liquid passes through the second filter screen and is discharged from the drainage branch pipe and the drainage pipe, while a small part of the clear liquid fails to pass through the second filter screen in time, and flows along the second filter screen tilted toward the lower left side onto the first guide slope, so that the scum on the second filter screen can be driven to flow to the first guide slope in time by this part of the water flow, thereby achieving the pre-draining of the scum on the water surface, effectively reducing the subsequent filtering burden of the second filter screen; When the shell moves down to the point where its bottom is lower than the drain pipe, the clear liquid flowing into the shell cannot be discharged from the drain pipe through the drain branch pipe, so that the clear liquid continues to accumulate in the shell until it flows over the partition to the first guide slope, thereby carrying the scum and suspended impurities on the first guide slope into the slag discharge pipe through the water flow, thereby preventing the scum and suspended impurities from continuing to accumulate on the first guide slope, and flushing the shell with the clear liquid, thereby eliminating the need to set up an additional cleaning pipeline in the shell.

DETAILED DESCRIPTION

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0019] Example 1 An intelligent partition treatment sewage pool, such as Figure 1-Figure 9 As shown, it includes a sewage treatment tank 1, an electric guide rail 2, a connecting frame 3 and a shell 4; a pre-storage area 1001 is arranged on the right side of the sewage treatment tank 1; a reaction area 1002 is arranged on the left side of the sewage treatment tank 1, and an aeration pipeline is arranged at the bottom of the reaction area 1002; a water inlet pipe is connected to the side wall of the pre-storage area 1001, and a connecting pipeline is arranged between the pre-storage area 1001 and the reaction area 1002; two electric guide rails 2 are fixedly connected to the left side of the reaction area 1002 and are symmetrically arranged in front and back; all the electric guide rails 2 are slidably connected to a connecting frame 3; a shell 4 is fixedly connected to the lower side of the connecting frame 3; It also includes a baffle 5, a second filter screen 6, a drainage branch pipe 101, a drainage pipe 102 and a slag discharge pipe 201; a water inlet 4001 is opened on the right side of the shell 4; a partition plate 4002 is fixedly connected in the shell 4; a baffle 5 that moves up and down is connected to the right side of the shell 4 through an electric slider, and the baffle 5 is sealed and slidably connected to the inner wall of the shell 4 to prevent sewage from directly penetrating into the shell 4 from between the baffle 5 and the shell 4; a through opening 5001 is opened on the baffle 5, and a first filter screen 5002 is arranged on the lower side of the through opening 5001, and the initial through opening 5001 is aligned with the water inlet 4001; the baffle 5 A second filter screen 6 is rotatably connected to the left side, and the connection between the baffle 5 and the second filter screen 6 is located between the through port 5001 and the first filter screen 5002; the other side of the second filter screen 6 is rotatably connected to the shell body 4; three drainage branch pipes 101 are connected to the lower side of the shell body 4, and the drainage branch pipes 101 are made of deformable material; all the drainage branch pipes 101 are commonly connected to the drainage pipe 102; the lower side of the shell body 4 is connected to the slag discharge pipe 201; the pipe mouth of the drainage branch pipe 101 is located on the right side of the pipe mouth of the slag discharge pipe 201, and the partition 4002 is located between the pipe mouth of the drainage branch pipe 101 and the pipe mouth of the slag discharge pipe 201.

[0020] A capacitive liquid level sensor 5003 is disposed on the right side of the baffle 5 , and the capacitive liquid level sensor 5003 is located on the upper side of the through opening 5001 . A vertical groove is provided at a corresponding position on the housing 4 to prevent the capacitive liquid level sensor 5003 from moving up and down.

[0021] The scraper 301 is also included; the scraper 301 is fixedly connected to the right side of the housing 4, the scraper 301 is located at the lower side of the water inlet 4001, and the scraper 301 is in close contact with the first filter screen 5002.

[0022] The second filter screen 6 is provided with two slide rails 6001 which are symmetrically arranged front and back; all the slide rails 6001 are slidably connected to a scraper 6002 .

[0023] The scraper 6002 is L-shaped to prevent the impurities from passing over the scraper 6002 when scraping the impurities.

[0024] Scraper 6002 is made of high-density metal.

[0025] A first guiding slope 4003 is provided on the lower inner side of the shell 4 and is inclined downward toward the pipe opening of the slag discharge pipe 201 ; the first guiding slope 4003 is located on the left side of the partition 4002 .

[0026] A second guide slope 4004 is provided at the bottom of the housing 4 and is inclined from the lower left side to the upper right side.

[0027] The drainage branch pipe 101 and the slag discharge pipe 201 are both inclined from the upper left side to the lower right side to avoid the drainage branch pipe 101 and the slag discharge pipe 201 from being accumulated at the side wall of the reaction zone 1002 and affecting the sludge flow.

[0028] During operation, the sewage is first gradually injected into the pre-storage area 1001 through the water inlet pipe. After the pre-storage area 1001 is filled with sewage, a reagent is added to pre-treat the sewage. Then, the sewage pre-treated in the pre-storage area 1001 is discharged into the reaction area 1002 through the connecting pipe between the pre-storage area 1001 and the reaction area 1002. Then, the aeration pipe in the reaction area 1002 is started to aerate the sewage, so as to promote the rapid reproduction of activated sludge microorganisms in the sewage and decompose the pollutants in the sewage. By zoning the sewage, large particles of suspended solids are first precipitated in the pre-storage area 1001, and heavy metals and toxic substances in the sewage are diluted or neutralized by adding reagents, so as to effectively reduce the sludge load of the subsequent reaction area 1002 and protect the activity of microorganisms. The reaction area 1002 is dedicated to aeration, which promotes the rapid proliferation of activated sludge microorganisms and ensures the degradation rate of pollutants, thereby effectively ensuring the treatment effect of sewage. Then, in the reaction area 1002, the activated sludge microorganisms are degraded, and the degradation rate of pollutants is ensured, thereby effectively ensuring the treatment effect of sewage. When the sewage in the reaction zone 1002 meets the discharge requirements, the aeration pipe stops aeration and stands for a period of time. The sludge gradually settles at the bottom of the reaction zone 1002. In order to process the next batch of sewage, the clear liquid on the upper layer needs to be discharged. The electric guide rail 2 is controlled to drive the connecting frame 3, the shell 4 and the parts connected thereto to move downward, so that the water inlet 4001 is immersed in water. Then the clear liquid can pass through the water inlet 4001 and the through port 5001 in turn, and then pass through the second filter screen 6. After falling below the second filter screen 6, it flows through the drainage branch pipe 101 and the drainage pipe 102 and is discharged outward. As the electric guide rail 2 drives the connecting frame 3, the shell 4 and the parts connected thereto to move downward at a uniform speed, the upper clear liquid is gradually discharged. At the same time, water is always taken from the surface of the water surface, which will not disturb the sludge in the lower layer. In addition, the suspended impurities in the clear liquid can be intercepted by the second filter screen 6 to prevent the suspended impurities from mixing into the clear liquid and being discharged together, thereby affecting the water quality of the clear liquid.

[0029] Driven by the water flow, the suspended impurities continue to adhere to the surface of the second filter screen 6. After a period of filtration, more suspended impurities accumulate on the surface of the second filter screen 6, which seriously affects the smoothness of the clear liquid passing through the second filter screen 6, causing the drainage speed to decrease, while the downward movement speed of the shell 4 remains unchanged, causing the water surface to move upward relative to the shell 4. When the water level rises and triggers the capacitive liquid level sensor 5003, it can be known that the port 5001 has been completely submerged in water. Fig. 9As shown, the electric slider is controlled to drive the baffle plate 5 to slide upward, so that the first filter screen 5002 is aligned with the water inlet 4001, and the baffle plate 5 drives the second filter screen 6 to rotate to tilt toward the lower left side. Since the scraper plate 6002 is made of high-density metal material, under the action of gravity, the scraper plate 6002 slides to the lower left side along the slide rail 6001, and the suspended impurities on the second filter screen 6 are scraped off by the scraper plate 6002, so that the suspended impurities fall onto the first guide slope 4003, and the scraper plate 6002 is L-shaped, so as to avoid impurities from being scraped. It passes over the scraper 6002 and separates impurities from the clear liquid through the partition 4002. The clear liquid in this state passes through the water inlet 4001 and the first filter screen 5002, and is discharged from the drainage branch pipe 101 and the drainage pipe 102, so that the suspended impurities can be intercepted by the unblocked first filter screen 5002, thereby ensuring normal drainage while quickly transferring the suspended impurities on the second filter screen 6. When all the suspended impurities on the second filter screen 6 are scraped off onto the first guide slope 4003, the electric slider can be controlled to drive the baffle 5 to reset downward.

[0030] It should be noted that when the baffle 5 is reset downward, the scraper 301 can scrape away the suspended impurities on the first filter screen 5002 to ensure that the subsequent clear liquid passes through the first filter screen 5002 normally.

[0031] However, in the process of aerating the sewage, a large number of bubbles generated by aeration will carry some impurities such as grease and fiber and float on the water surface, gradually forming a layer of scum on the surface of the sewage, so that when draining, part of the scum will flow into the water inlet 4001 together with the clear liquid. At this time, if it is intercepted by the second filter 6, since the scum contains more impurities such as grease and fiber, the scum is very easy to adhere to the second filter 6, causing the second filter 6 to be blocked, which leads to a heavy filtering burden on the second filter 6. Before the drainage operation is performed, the electric slider is first controlled to drive the baffle 5 to slide upward, so that the baffle 5 moves up to block the water inlet 4001. At this time, the baffle 5 drives the second filter screen 6 to rotate to tilt toward the lower left side, and then the electric guide rail 2 drives the connecting frame 3 and the shell 4 and the connected parts to move downward, so that the baffle 5 is completely immersed in the water, and the water flow carries the scum over the baffle 5 and falls onto the second filter screen 6, and then the scum is intercepted by the second filter screen 6, and most of the clear liquid passes through the second filter screen 6 and is discharged from the drainage branch pipe 101 and the drainage branch pipe 101. The first filter screen 6 is inclined toward the left lower side, and the second filter screen 6 is inclined toward the left lower side. Therefore, the scum on the second filter screen 6 can be driven to flow to the first guide slope 4003 in time by this part of water flow, and then flow to the outlet of the slag discharge pipe 201 along the first guide slope 4003, and then be discharged outward through the slag discharge pipe 201, thereby achieving the discharge of scum on the water surface in advance, effectively reducing the subsequent filtering burden of the second filter screen 6. After the scum on the water surface is discharged, the electric guide rail 2 can be controlled to drive the shell 4 to move up to the water inlet 4001 and be flush with the water surface, and the electric slider can be controlled to drive the baffle 5 to reset downward so that the opening 5001 is aligned with the water inlet 4001 to perform conventional drainage operations. The suspended impurities in the clear liquid are intercepted by the second filter screen 6 inclined toward the lower right side. At this time, the clear liquid can all pass through the second filter screen 6 and be discharged from the drainage branch pipe 101, thereby avoiding partial clear liquid from being discharged from the slag discharge pipe 201, thereby reducing the loss of clear liquid.

[0032] It should be noted that when the shell 4 moves downward and is immersed in water, the second guiding slope 4004 inclined from the lower left side to the upper right side can push the scum on its lower side to move rightward to avoid that the scum is pressed into the water by the shell 4 and cannot be discharged.

[0033] like Fig.10As shown, when the shell 4 moves down to its bottom below the drain pipe 102, the clear liquid flowing into the shell 4 cannot be discharged from the drain pipe 102 through the drain branch pipe 101, so that the clear liquid continues to accumulate in the shell 4 until it flows over the partition 4002 to the first guide slope 4003, thereby carrying the scum and suspended impurities on the first guide slope 4003 through the water flow into the slag discharge pipe 201, avoiding the continuous accumulation of scum and suspended impurities on the first guide slope 4003, and flushing and cleaning the shell 4 with the clear liquid, so there is no need to set up an additional cleaning pipeline in the shell 4, and then control the electric guide rail 2 to drive the shell 4 to reset upward. During this process, the clear liquid in the shell 4 is discharged from the slag discharge pipe 201 and the drain branch pipe 101 respectively.

[0034] Example 2 On the basis of Example 1, Figure 4-Figure 8 As shown, it also includes an electric shaft 202; the electric shaft 202 is connected to the housing 4 through a fixed plate, the electric shaft 202 is located on the upper side of the slag discharge pipe 201, and four cutting blades 20201 are fixedly connected to the lower side of the electric shaft 202.

[0035] When the clear liquid accumulates continuously in the shell 4 and flows over the partition 4002 to the first guide slope 4003, and carries the scum and suspended impurities on the first guide slope 4003 through the water flow into the slag discharge pipe 201, since the scum contains fiber impurities, in order to prevent the fiber impurities from clogging the slag discharge pipe 201, the cutting blade 20201 is driven to rotate by the electric shaft 202 to cut the fiber impurities in the scum into pieces by the cutting blade 20201, thereby preventing the fiber impurities from clogging the slag discharge pipe 201.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
