Description

Technical Field

[0003] In the prior art, microbial decomposition and purification are often used in the treatment process of wastewater generated by meat processing to achieve the purpose of removing organic pollutants. However, in this solution, the sewage injected into the treatment tank will be stratified, and the activated sludge will accumulate at the bottom. Even through aeration, the decomposition effect of the sewage on the top layer and the sewage on the bottom layer cannot be kept consistent, resulting in differences in sewage purification effects in different areas. On the other hand, the sedimentation purification process needs to be left to stand for a period of time, and after the sedimentation is completed, the sewage needs to be discharged and then injected into the subsequent sewage, resulting in the injection and discharge processes being independent of each other, which prolongs the treatment cycle.

This treatment equipment is used to purify the wastewater generated during the halal meat processing process through microbial decomposition. Figure 1 As shown, the sewage is directly injected from the injection port 4 at the left end into the leftmost microbial decomposition pool 2. As the injected sewage increases, the liquid level exceeds the overflow port 17 and enters another microbial decomposition pool 2. The process is repeated until it enters the microbial decomposition pool 2 at the edge. At this time, the sewage in the microbial decomposition pool 2 is pumped out by the pressure pump 11 and transported to the sedimentation tank 3 for sedimentation treatment. The injection position is the left side of the partition component 6. After the filling is completed, it is allowed to stand. Finally, the sewage after sedimentation treatment can be pumped out through external drainage equipment. At the same time, the outlet position of the diversion pipe 13 is controlled to inject the subsequent sewage into the right side of the partition component 6. At the same time, the motor 26 is started to control the partition component 6 to move toward the left end. At this time, the sewage discharge and injection process can be realized simultaneously.

[0029] In this embodiment, the overflow mechanism 5 includes a clamp 16 and an overflow pipe 18, a first gap 20 is provided between the bottom of the clamp 16 and the bottom of the treatment tank 1, a second gap 21 is provided between the bottom of the partition 8 and the bottom of the treatment tank 1, and the height of the second gap 21 is less than the height of the first gap 20, an overflow port 17 is provided on the top of the surface of each clamp 16, the overflow pipe 18 is connected to one side of the overflow port 17, and a guide port 19 is connected to the bottom of the overflow pipe 18, the first gap 20 and the second gap 21 are used to guide the flow of the activated sludge at the bottom, and both ends of each clamp 16 and the partition 8 are welded to the inner wall of the treatment tank 1 as a whole. A plurality of microbial decomposition tanks 2 are arranged in the treatment tank 1, and each microbial decomposition tank 2 is separated by an overflow mechanism 5, so when the injected sewage is purified, the sewage at any position can be fully contacted and mixed with the microorganisms in the activated sludge during the flow process, thereby improving the uniformity of sewage purification.

[0030] Specifically, after the sewage is accumulated inside the microbial decomposition tank 2, the organic pollutants are decomposed with the help of the activated sludge at the bottom. The bottom of each microbial decomposition tank 2 is blocked by the accumulated activated sludge to block the first gap 20 at the bottom, so that the injected sewage cannot flow from the first gap 20 toward the inside of the microbial decomposition tank 2 on the other side, until the liquid level inside the microbial decomposition tank 2 exceeds the overflow port 17, and then it can flow toward the microbial decomposition tank 2 at the rear end, and lift the sewage from the bottom layer to the top layer during the flow process, so that all the sewage can realize the flow process from the bottom layer to the top layer, and fully contact with the microorganisms in the water during the flow process to achieve the purpose of decomposing organic pollutants.

[0031] In this embodiment, the partition assembly 6 includes a baffle 22 and a screw rod 25, the top of the baffle 22 is integrally formed with a second convex plate 23, one side of the bottom of the baffle 22 is provided with a first mud discharge port 29, and a bottom plate 31 is welded to the other side of the bottom of the baffle 22, a second mud discharge port 30 is provided at the top of one end of the bottom plate 31, and a third mud discharge port 32 is provided at the other end of the bottom plate 31, and hanging plates 27 are integrally formed on both sides of the top of the baffle 22, and a guide rod 28 is passed through the inside of the hanging plate 27, a base 14 is welded to the top of the treatment pool 1, and both ends of the guide rod 28 are plugged into the inside of the base 14, a threaded sleeve 24 is provided in the middle of the second convex plate 23, and the screw rod 25 passes through the inside of the threaded sleeve 24, and a motor 26 is installed at one end of the screw rod 25, and the outer shell of the motor 26 is fixed to the surface of the first convex plate 15 with screws, and both sides of the baffle 22 are in contact with the inner wall of the treatment pool 1.

[0032] Specifically, the partition assembly 6 divides the sedimentation tank 3 into two areas, and the entire baffle 22 can move horizontally. During this process, the motor 26 is started to drive the screw rod 25 to rotate. The screw rod 25 cooperates with the threaded sleeve 24 to directly control the entire baffle 22 to slide along the inner wall of the sedimentation tank 3, and the guide rods 28 at both ends are used to provide a guiding and limiting effect on the baffle 22.

[0033] In this embodiment, the mud discharge assembly 7 includes a collecting pipe 34 and an independent mud discharge pipe 35, one end of the collecting pipe 34 is plugged into the surface of the sludge pump 33, the number of the independent mud discharge pipes 35 is three, and the top of each independent mud discharge pipe 35 is connected to the inside of the collecting pipe 34, and the surface of each independent mud discharge pipe 35 is installed with a valve 36, and the inside of the three independent mud discharge pipes 35 is respectively connected to the first mud discharge port 29, the second mud discharge port 30, and the third mud discharge port 32. The first mud discharge port 29 and the bottom plate 31 are pressed at the bottom of the treatment tank 1, and the height of the bottom plate 31 is the same as the height of the second gap 21. The equipment is connected between each microbial decomposition tank 2 through the gap at the bottom, so it can ensure that there is enough activated sludge accumulated at the bottom of each microbial decomposition tank 2, and by regularly starting the mud discharge assembly 7 and cooperating with the movable partition assembly 6, the activated sludge and sedimentation part accumulated at the bottom of each microbial decomposition tank 2 and the sedimentation tank 3 can be directly discharged quickly during the movement of the partition assembly 6.

[0034] Specifically, when it is necessary to discharge the sludge inside the treatment tank 1, the sludge pump 33 is directly started, and only the independent sludge discharge pipe 35 and the corresponding valve 36 connected to the top of the first sludge discharge port 29 are opened. At the same time, the motor 26 is controlled to rotate to drive the entire baffle 22 to move toward the right end. During the movement, the sediment accumulated at the bottom can be drawn in from the first sludge discharge port 29, and finally extracted through the sludge pump 33 along the independent sludge discharge pipe 35 and the collecting pipe 34. When the baffle 22 moves to the rightmost end, the valve 36 is closed, and the other two valves 36 are opened at the same time. At this time, the sediment accumulated on the other side of the baffle 22 can be discharged upward from the second sludge discharge port 30 at the same time, and the sludge part at the bottom of each microbial decomposition tank 2 passes through the first gap 20 and the second gap 21 along the third sludge discharge port 32 and it in turn, so as to achieve the purpose of extracting and discharging the sludge from each microbial decomposition tank 2.

[0035] This embodiment also provides a processing method using the above processing device, comprising the following steps:

[0036] S1, injecting the meat processing wastewater into the microbial decomposition pool 2 in the treatment pool 1, directly transporting the wastewater to the inner part of the microbial decomposition pool 2 at the outermost edge during the injection, and the thickness of the activated sludge at the bottom of the treatment pool 1 always exceeds the height position of the first gap 20;

[0037] S2, the sewage passes through each overflow mechanism 5 in turn through the overflow mechanism 5, and the organic pollutants are decomposed by the activated sludge at the bottom. The bottom of each microbial decomposition tank 2 is blocked by the accumulated activated sludge to make the injected sewage flow toward the rear microbial decomposition tank 2 after the liquid level exceeds the overflow port 17, and the sewage is lifted from the bottom to the top during the flow;

[0038] S3, the sewage is introduced into the sedimentation tank 3 by the pressure pump 11, and concentrated on one side of the partition component 6 for sedimentation treatment. During the sedimentation process, the sewage inside each microbial decomposition tank 2 no longer flows, and only continues to flow after the sedimentation is completed, and the microbial decomposition process is continuously realized in a static state;

[0039] S4, after the sedimentation is completed, the sewage is directly extracted through the external drainage equipment, and the subsequent sewage introduction position is changed to the other side of the partition component 6. The sewage that has flowed to the last microbial decomposition tank 2 is transported to the sedimentation tank 3 through the pressure pump 11. The process is controlled by controlling the two diversion pipes 13 to be opened in sequence to control the specific position of the sewage introduction into the sedimentation tank 3, and the sewage on both sides of the partition component 6 is always controlled to be extracted and injected respectively in the process;

[0040] S5, repeating steps 3 and 4 to continuously purify the sewage, and discharging the precipitated sewage intermittently;

[0041] S6. Regularly start the mud discharge component 7, control the valve 36 to open in sequence, and extract the sludge on both sides of the partition component 6 and inside the microbial decomposition tank 2 in sequence. In this process, the motor 26 is also controlled to rotate to drive the entire baffle 22 to move toward the right end, and the sediment accumulated at the bottom of the sedimentation tank 3 is discharged upward from the first mud discharge port 29 and the second mud discharge port 30, while the sludge part at the bottom of each microbial decomposition tank 2 passes through the first gap 20 and the second gap 21 along the third mud discharge port 32 and in sequence, thereby achieving the purpose of extracting and discharging the sludge from each microbial decomposition tank 2.

[0042] During the sedimentation process of this treatment method, the sedimentation tank 3 is separated into two areas by the partition component 6, and the translational movement of the partition component 6 can synchronize the discharge process of the precipitated sewage with the subsequent sewage injection process, thereby improving the sewage treatment efficiency.
