Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment, and in particular to a flow self-regulating sedimentation tank based on high-concentration organic wastewater treatment. Background Art

[0002] In recent years, with the rapid development of industry, sewage pollution has become increasingly serious; the country has continuously improved wastewater treatment standards, and wastewater discharge has become more stringent; the A-stage treatment process based on the AB method is used to treat high-concentration organic wastewater, which mainly includes biological carbon removal aeration tanks and sedimentation tanks; due to the high organic content of the treated wastewater, microorganisms quickly utilize part of the organic matter while adsorbing a large amount of large-molecule organic matter, and the microorganisms grow and multiply rapidly; the high-concentration sludge formed needs to be precipitated and separated in the sedimentation tank, and the separated supernatant is discharged from the system through the overflow weir, and the sludge that is further concentrated and precipitated in the mud hopper is returned to the front end of the system through the sludge reflux, and part of it is discharged from the system to remove organic pollutants.

[0003] Sedimentation tanks with sludge concentrations as high as 10,000 mg / L or more need to consider the height limit of the entire equipment in integrated treatment equipment, and generally use a multi-sludge hopper design; during actual operation, due to the differences in the concentration of sludge settled in each hopper, the distance from the sludge return pump, the length of the sludge discharge pipeline and other factors, it is impossible to ensure that each hopper can discharge sludge evenly. In some hoppers, the sludge concentration of concentrated sludge is even very high, and the fluidity is extremely poor, resulting in blockage and sludge discharge. Sludge hoppers that do not discharge sludge for a long time will cause uneven sludge levels in the sedimentation tank. At the same time, the anaerobic gas production causes the precipitated sludge to float, affecting the effluent water quality and ultimately affecting the operation of the entire biochemical system.

[0004] Therefore, the stable operation of the inlet and outlet water of the sedimentation tank as well as the sludge return and discharge is particularly important. In the actual operation process, in order to ensure the stable operation of the system, the operator needs to frequently pay attention to the sedimentation water inlet, sludge return volume, and the operation of each hopper of the multiple hoppers, which greatly increases the burden on the operator.

[0006] As an improvement of the above scheme, the sedimentation tank body is provided with four mud buckets, which are arranged in an array and are arranged in close contact with each other at the bottom of the sedimentation tank body. The upper edges of two adjacent mud buckets are in close contact with each other, and the upper edge width of the mud bucket is greater than the lower edge width of the mud bucket.

[0007] As an improvement of the above solution, the mud bucket is in the shape of an inverted four-pole cone, which is formed by four slopes, and the position near the bottom of the slope is connected to the mud outlet pipe.

[0009] As an improvement of the above scheme, one end of the regulating pipe extends horizontally toward the sedimentation tank body and is connected to the first water inlet pipe, and the other end extends downward along the inner wall of the aeration tank. The regulating pipe is provided with a regulating branch pipe extending downward along the inner wall of the sedimentation tank body.

[0010] As an improvement of the above scheme, the regulating control device includes a bidirectional impeller water pump arranged on the side of the regulating pipeline close to the aeration tank, a first regulating electric valve arranged on the side of the regulating pipeline close to the first water inlet pipeline, and a second regulating electric valve arranged on the regulating branch pipeline.

[0011] As an improvement of the above scheme, the second electric control device includes a mud discharge branch pipe and a mud discharge electric valve arranged on the mud discharge branch pipe. The mud discharge branch pipe and the mud discharge electric valve match the number of the mud buckets.

[0021] like Figures 1 to 3 As shown, a flow self-regulating sedimentation tank based on high-concentration organic wastewater treatment includes a sedimentation tank body 1 and an aeration tank 3. The aeration tank 3 is provided on one side adjacent to the sedimentation tank body 1, and a regulating pipe 4 connected to the aeration tank 3 is provided on the other side close to the top of the sedimentation tank body 1. The regulating pipe 4 is provided with a regulating control device, and an aeration device 6 is provided at the bottom of the aeration tank 3; A water inlet pipe 7 is provided on one side near the top of the sedimentation tank body 1, and a first electric control device is provided between the water inlet pipe 7 and the sedimentation tank body 1, wherein the first electric control device includes a water inlet pump 11, a water inlet flow meter 12 and a water inlet electric valve 13; A plurality of mud hoppers 2 are provided near the bottom of the sedimentation tank body 1, and a mud discharge pipe 8 is provided at the bottom of the mud hopper 2. The mud discharge pipe 8 is respectively connected to a sludge return pipe 9 and a sludge discharge pipe 10. A second electric control device is provided at one end of the mud discharge pipe 8 connected to the mud hopper 2, and a third electric control device is provided between the mud discharge pipe 8 and the sludge return pipe 9 and the sludge discharge pipe 10.

[0022] In the structure of the sedimentation tank body 1 of the present invention, a water inlet pipe 7 is provided on the top of the sedimentation tank body 1, and the water inlet pipe 7 is used to connect to the carbon removal aeration tank in the upper station. A regulating pipe 4 is provided between the sedimentation tank body 1 and the aeration tank 3. A mud hopper 2 is provided at the bottom of the sedimentation tank body 1, and a mud outlet pipe 8 is connected to the bottom of the mud hopper 2. The water inlet pipe 7 is connected with a first electric control device, which includes a water inlet pump 11, a water inlet flowmeter 12 and a water inlet electric valve 13. The water inlet amount of the sedimentation tank body 1 is controlled by controlling the opening of the water inlet electric valve 13, and the total water inlet amount of the sedimentation tank body 1 is calculated by the opening time of the water inlet electric valve 13 and the flow rate of the water inlet flowmeter 12; The mud hopper 2 is provided with a mud discharge pipe 8, and the mud discharge pipe 8 is connected to a third electric control device. The weight of mud and water flowing out of the sedimentation tank main body 1 is recorded by the water outlet flow meter 17, and the sludge return amount and sludge discharge amount of the sedimentation tank main body 1 are controlled by staggered opening and closing of the return electric valve 18 and the mud discharge electric valve 19.

[0023] When the liquid level in the sedimentation tank body 1 is too high, the regulating pipe 4 participates in the flow control of the sedimentation tank body 1, and pumps the water in the sedimentation tank into the aeration tank 3, thereby relieving the pressure of the sedimentation tank; In the structure of the water inlet pipe 7 of the present invention, the water inlet pipe 7 includes a first water inlet pipe 701 vertically arranged in the middle of the sedimentation tank body 1 and a second water inlet pipe 702 connected to the previous process, the second water inlet pipe 702 horizontally extends toward the sedimentation tank body 1 and is connected to the first water inlet pipe 701, the first water inlet pipe 701 is vertically arranged above the middle of the sedimentation tank body 1, and the water inlet pump 11, the water inlet flow meter 12 and the water inlet electric valve 13 are sequentially arranged along the water flow direction of the second water inlet pipe 702; Specifically, the muddy water treated in the carbon removal aeration tank enters the second water inlet pipe 702 and the first water inlet pipe 701 through the water inlet meter and the water inlet electric valve 13 in sequence under the suction action of the water inlet pump 11, and the water inlet meter only records the water inlet flow of the second water inlet pipe 702; In the structure of the regulating pipe 4 of the present invention, the aeration tank 3 is provided on the side adjacent to the sedimentation tank body 1, and the regulating pipe 4 connected to the aeration tank 3 is provided on the other side close to the top of the sedimentation tank body 1, and a regulating control device is provided on the regulating pipe 4, and an aeration device 6 is provided at the bottom of the aeration tank 3. The aeration tank 3 and the regulating pipe 4 are used to divert excessive flow in the sedimentation tank. When the sedimentation tank body 1 is in a high-load working state and sludge blockage occurs, the sedimentation tank body 1 will be in an overloaded operation state for a certain reaction time. The regulating pipe 4 diverts muddy water in the sedimentation tank in the overloaded operation state to prevent the water volume in the sedimentation tank body 1 from being in an overloaded state for a long time, thereby causing damage to the equipment; Further, in the above scheme, one end of the regulating pipe 4 extends horizontally toward the sedimentation tank body 1 and is connected to the first water inlet pipe 701, and the other end extends downward along the inner wall of the aeration tank 3, and the regulating pipe 4 is provided with a regulating branch pipe 405 extending downward along the inner wall of the sedimentation tank body 1, and the bottom end level of the regulating branch pipe 405 is flush with the liquid level of the sedimentation tank body 1 under the high-load working state; Further, in the above scheme, the regulating control device includes a bidirectional impeller water pump 401 arranged on the side of the regulating pipeline 4 close to the aeration tank 3, a first regulating electric valve 402 arranged on the side of the regulating pipeline 4 close to the first water inlet pipeline 701, and a second regulating electric valve 403 arranged on the regulating branch pipeline 405; In the first embodiment of the present invention, it should be noted that when the sedimentation tank body 1 is in a high-load working state, the water inlet flow rate of the sedimentation tank body 1 is the same as the water outlet flow rate. When sludge blockage occurs, the water inlet flow rate of the sedimentation tank body 1 is greater than the water outlet flow rate, and the sedimentation tank body 1 is in an overload operation state. When the liquid level rises to the position of the water level sensor, the first regulating electric valve 402 is closed, the second regulating electric valve 403 is closed, and the two-way impeller water pump 401 pumps the mud-water mixture in the sedimentation tank body 1 into the aeration tank 3, so that the liquid level in the sedimentation tank body 1 is in a safe position, which protects the sedimentation tank body 1. Further, after relieving the flow pressure of the sedimentation tank body 1, when the water outflow of the sedimentation tank body 1 is greater than the water inflow, the liquid level in the sedimentation tank body 1 will drop, the first regulating electric valve 402 will be opened, the second regulating electric valve 403 will be closed, and the two-way impeller water pump 401 will pump the mud-water mixture in the aeration tank 3 into the sedimentation tank body 1, thereby relieving the pressure of the sedimentation tank; In this embodiment, the aeration tank 3 is connected to the sedimentation tank body 1 only through the regulating pipe 4, the end of the regulating pipe 4 is connected to the first water inlet pipe 701, the second water inlet pipe 702 and the regulating pipe 4 are both one-way pipes, and the water volume transported by the first water inlet pipe 701 includes the water inlet flow of the second water inlet pipe 702 and the reflux flow of the regulating pipe 4; It should be noted that the water inlet electric valve 13 controls the opening and closing of the water inlet pipe 7, the water inlet flow meter 12 records the flow of the second water inlet pipe 702, and calculates the muddy water flow entering the sedimentation tank body 1 according to the opening time of the water inlet electric valve 13; The sludge return pump 16 is used to extract the sludge deposited at the bottom of the sludge hopper 2, and to pump the mixture of the settled sludge and a small amount of water into the sludge discharge pipe 8. The return electric valve 18 and the sludge discharge electric valve 19 control the return or discharge of the extracted sludge. The water outlet flow meter 17 records the flow of the sludge discharge pipe 8, and calculates the sludge and water flow discharged from the sedimentation tank body 1 according to the opening time of the return electric valve 18 and the sludge discharge electric valve 19. Furthermore, the muddy water flow rate entering the sedimentation tank body 1 is equal to the muddy water flow rate discharged from the sedimentation tank body 1. When the sedimentation tank body 1 is operated at high load, the opening of the electric valve is adjusted by the difference between the two flow meters to realize flow control of the sedimentation tank body 1, so as to achieve the purpose of automatic water discharge and adjustment of water discharge and mud discharge; The flow rate diverted from the aeration tank 3 is equal to the difference flow rate of the two flow meters in the sedimentation tank main body 1. After overload operation, the water inlet electric valve 13 on the second water inlet pipe 702 is in a closed state, and the regulating pipe 4 transports the water in the aeration tank 3 back to the sedimentation tank main body 1. After the liquid level in the sedimentation tank main body 1 is at a safe position, the water inlet electric valve 13 is reopened.

[0024] like Figure 2 and Figure 4 As shown, in the second embodiment of the present invention, the sludge return pipe 9 is connected to the aeration tank 3, and a regulating pipe 4 is connected between the aeration tank 3 and the sedimentation tank body 1. The regulating pipe 4 is also provided with a shunt meter. The aeration tank 3 has a shunt function consistent with the first embodiment, which relieves the pressure of the sedimentation tank body 1. When the aeration tank 3 does not perform a shunt operation, the first regulating electric valve 402 and the second regulating valve are both in a closed state, and the sludge return pipe 9 discharges the return sludge of the sedimentation tank body 1 into the aeration tank 3. The inspector can detect the particles, concentration, biological activity and sanitary safety of the return sludge in the aeration tank 3 to ensure that the return sludge maintains a certain biological activity and does not contain harmful pathogens or pollutants. It should be noted that, when the sedimentation tank body 1 is in a stable working state, the return electric valve 18 and the mud discharge electric valve 19 are in a staggered opening state or a simultaneous opening state, the regulating pipe 4 is in a closed state, and the aeration tank 3 is used to detect the return sludge; when the sedimentation tank body 1 is in an overload operation state, the return electric valve 18 is in a closed state, the mud discharge electric valve 19 is in a continuously open state, the regulating pipe 4 is in an open state, and the aeration tank 3 is used to divert the flow of the sedimentation tank body 1; Furthermore, the diversion meter records the flow of the aeration tank 3 in the diversion state, and obtains the diversion flow in combination with the diversion time of the aeration tank 3. When the sedimentation tank main body 1 is in normal working condition, the aeration tank 3 re-inputs the diversion flow into the sedimentation tank main body 1 through the regulating pipe 4 to maintain the balance between the water inlet and water outlet of the sedimentation tank main body 1.

[0025] It should be noted that an aeration device 6 is provided at the bottom of the aeration tank 3 . When the aeration tank 3 is in a diversion working state or a sludge return transfer state, the aeration device 6 can continuously aerate to prevent sludge from being deposited at the bottom of the aeration tank 3 .

[0026] In the structure of the mud hopper 2 of the present invention, there are four mud hoppers 2, which are arranged in an array and fit each other at the bottom of the sedimentation tank body 1. The water outlet of the first water inlet pipe 701 is aligned with the intersection of the mud hoppers 2 arranged in the array, so as to reduce the excessive accumulation of sludge in one of the mud hoppers 2. The upper edges of two adjacent mud hoppers 2 fit each other, and the width of the upper edge of the mud hopper 2 is greater than the width of the lower edge of the mud hopper 2. The mud hopper 2 is in the shape of an inverted four-pole cone, which is formed by four slopes 201. The position near the bottom of the slope 201 is connected to the mud discharge pipe 8. When the sludge is precipitated, it slides along the slope 201 and is deposited at the bottom of the mud hopper 2, so as to avoid local accumulation of soil. The position near the bottom of the slope 201 is connected to the mud discharge pipe 8.

[0027] Furthermore, in the above scheme, the second electric control device includes a mud discharge branch pipe 15 and a mud discharge electric valve 19 arranged on the mud discharge branch pipe 15. The mud discharge branch pipe 15 and the mud discharge electric valve 14 match the number of the mud bucket 2. One end of the mud discharge branch pipe 15 is connected to the bottom of the mud bucket 2, and the other end is connected to the mud discharge pipe 8.

[0028] It should be noted that a mud discharge branch pipe 15 is connected to the bottom of each mud hopper 2, and the opening and closing of the mud discharge branch pipe 15 is controlled by the mud discharge electric valve 14. The mud discharge is cyclically controlled by the second electric control device to control the mud discharge of the mud discharge electric valve 14 corresponding to each mud hopper 2 to prevent the situation in which the sludge concentration concentrated and precipitated in individual mud hoppers 2 is extremely high, affecting the sedimentation effect and the water quality of the effluent, so as to achieve the goal of uniform mud discharge.

[0029] Furthermore, in the above scheme, the third electric control device includes a sludge return pump 16, an outlet flow meter 17, a return electric valve 18 and a sludge discharge electric valve 19, the sludge return pump 16 and the outlet flow meter 17 are arranged in sequence along the mud and water flow direction of the mud outlet pipe 8, the return electric valve 18 is arranged on the sludge return pipe 9 connected to the mud outlet pipe 8, and the mud discharge electric valve 19 is arranged on the sludge discharge pipe 10 connected to the mud outlet pipe 8.

[0030] Furthermore, in the above solution, a water level sensor is provided on the inner wall of the sedimentation tank body 1 , and the level of the water level sensor is higher than the level of the end of the regulating branch pipe 405 .

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
