Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a device for treating wastewater containing raw materials of heterocyclic compounds. Background Art

[0002] API wastewater is wastewater generated during the production process of APIs. The production of APIs usually includes multiple links such as chemical synthesis, fermentation, and extraction. A large amount of water is used in these links for reaction, washing, and separation operations, thereby generating wastewater. Among them is a kind of wastewater containing heterocyclic compound APIs. This API wastewater containing heterocyclic compounds is a kind of wastewater generated in the production process of APIs containing heterocyclic structures. Heterocyclic compounds have the characteristics of long chemical synthesis steps and stable molecular structures. Heterocyclic pharmaceutical wastewater generally has high salt content, high COD, and high total nitrogen. It usually has strong biological toxicity and poses a serious threat to the ecosystem. It is one of the difficulties in the current treatment of pharmaceutical API water.

[0003] For pharmaceutical wastewater containing heterocyclic compounds that are difficult to degrade, the current mainstream method is a combination of physicochemical pretreatment, biochemical treatment, and terminal oxidation treatment. It uses Fendon oxidation to perform physicochemical pretreatment on pesticide wastewater and then biochemical treatment, so that the COD value of pharmaceutical wastewater containing heterocyclic compounds can meet the requirements for wastewater discharge.

[0004] In the existing procedures for treating pharmaceutical wastewater containing heterocyclic compounds, during biochemical treatment, due to changes in wastewater quality and water volume, in order to fully decompose the heterocyclic compounds contained in the bulk drug wastewater, a large number of bacterial strains need to be added to ensure that the organic pollutants in the pharmaceutical wastewater can be degraded more thoroughly. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a device for treating wastewater containing heterocyclic compound raw materials, so as to solve the technical problem that a large number of bacterial strains need to be added to degrade organic pollutants in the traditional process of treating pharmaceutical wastewater containing heterocyclic compounds.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a wastewater treatment device containing heterocyclic compound raw materials, comprising a main pool and a sub-pool, wherein a motor is installed at the bottom of the main pool, a rotating rod is provided at the output end of the motor, and the rotating rod passes through the bottom of the main pool, one end of the rotating rod is connected to a turntable, a fixed column is fixed at the top of the turntable, and a plurality of groups of stirring blades are provided on the outer wall of the fixed column, a connecting pipe is installed at the top of the fixed column, a support plate is fixed at the top of the main pool, and a first blower is installed at the bottom of the support plate, a first ventilation pipe is provided at the bottom end of the first blower, and the first ventilation pipe is movably connected to the connecting pipe.

[0007] By adopting the above technical solution, the problem of the traditional process of treating pharmaceutical wastewater containing heterocyclic compounds, which requires the addition of a large number of bacterial strains to degrade organic pollutants in the pharmaceutical wastewater, is solved. A stirring blade is installed inside the main tank, and the stirring blade stirs the raw material pharmaceutical wastewater poured into the main tank. Since different batches of raw material pharmaceutical wastewater may differ in the type and concentration of heterocyclic compounds and the content of other pollutants, the stirring blade can stir and mix the raw material pharmaceutical wastewater from different periods or different sources, so that the water quality of the raw material pharmaceutical wastewater is more uniform, reducing the impact on the subsequent biochemical treatment system. In addition, the auxiliary tank can share and store excess wastewater poured into the main tank, thereby ensuring that the subsequent biochemical treatment system can operate continuously and stably.

[0008] The present invention is further configured such that the stirring blade is arranged obliquely, and the middle portion of the stirring blade bulges outwards.

[0009] By adopting the above technical solution, the stirring blades are arranged at an angle, so that when the stirring blades stir the raw wastewater in the main pool, the resistance of the raw wastewater to the stirring blades can be reduced.

[0010] The present invention is further configured such that a ventilation duct and a ventilation hole are provided inside the fixing column, and the ventilation duct is connected to the inside of the connecting pipe.

[0011] By adopting the above technical solution, the gas transmitted by the blower is transmitted into the ventilation duct inside the fixed column through the ventilation pipe, and then the ventilation duct transmits the gas to multiple groups of ventilation holes, so that the gas can be discharged from the air outlet on one side of the stirring blade.

[0012] The present invention is further configured such that a plurality of air outlet holes are provided on one side of the stirring blade, and the air outlet holes are located on the back of the stirring blade.

[0013] By adopting the above technical solution, when the stirring blade is stirring, the water pressure on the back of the stirring blade is less than the water pressure on the front of the stirring blade. The air outlet holes arranged on the back of the stirring blade discharge sufficient air, thereby increasing the oxygen content in the raw wastewater, which facilitates the next process to accelerate the degradation of compounds in the wastewater by microorganisms.

[0014] The present invention is further configured such that a first water inlet pipe and a first water outlet pipe are provided on the outer wall of the main pool, and the diameter of the first water inlet pipe is greater than the diameter of the first water outlet pipe.

[0015] By adopting the above technical solution, the raw wastewater generated by the production of medicines enters the main pool through the first water inlet pipe. The diameter of the first water outlet pipe is smaller than that of the first water inlet pipe, so that the water discharge from the first water outlet pipe is relatively stable, allowing subsequent programs to run slowly.

[0016] The present invention is further configured such that a secondary pool is provided on one side of the main pool, and the bottom end of the secondary pool is higher than the bottom end of the main pool.

[0017] By adopting the above technical solution, when a large amount of raw wastewater is poured into the main pool, the excess raw wastewater can flow into the auxiliary pool through the second water inlet pipe. The auxiliary pool shares the excess raw wastewater with the main pool. When the raw wastewater in the main pool is less, the wastewater in the auxiliary pool is discharged into the main pool to ensure that the main pool can continuously discharge raw wastewater.

[0018] The present invention is further configured such that a second water inlet pipe is provided on one side of the main pool, and the second water inlet pipe is connected to the interior of the main pool and the auxiliary pool, and the second water inlet pipe is higher than the first water inlet pipe.

[0019] By adopting the above technical solution, when the wastewater in the main pool overflows the top of the first water inlet pipe, the wastewater flows into the auxiliary pool through the second water inlet pipe, sharing the water volume for the main pool.

[0020] The present invention is further configured such that a second water outlet pipe is provided on one side of the main pool, and the second water outlet pipe is higher than the first water outlet pipe.

[0021] By adopting the above technical solution, when there is less wastewater in the main pool, the personnel opens the valve of the second outlet pipe, and the wastewater in the auxiliary pool flows into the main pool through the second outlet pipe. The second outlet pipe is higher than the first outlet pipe, so that all the wastewater in the auxiliary pool can flow into the main pool and provide wastewater for the main pool.

[0022] The present invention is further configured such that a valve is installed in the middle of the second water outlet pipe, and the second water outlet pipe is controlled by the valve to drain water.

[0023] By adopting the above technical solution, when it is necessary to replenish wastewater from the auxiliary pool to the main pool, personnel can control the valve on the second outlet pipe to discharge the wastewater in the auxiliary pool into the main pool.

[0024] The present invention is further configured such that the flux of the air outlet is smaller than the flux of the ventilation hole, and the wind pressure of the gas discharged from the air outlet is greater than the water pressure inside the main pool.

[0025] By adopting the above technical solution, the amount of air transmitted by the ventilation holes is greater than the amount of air discharged by the air outlets, so that the air outlets on the stirring blades can all discharge air. At the same time, the wind pressure of the gas discharged by the air outlets is greater than the water pressure inside the main pool, preventing the raw wastewater in the main pool from flowing back into the air outlets.

[0026] In summary, the present invention has the following beneficial effects:

[0027] 1. The utility model solves the problem of the need to add a large number of bacterial strains to degrade organic pollutants in the traditional process of treating pharmaceutical wastewater containing heterocyclic compounds by providing a main tank, a secondary tank and a stirring blade. The stirring blade is installed inside the main tank to stir the API wastewater poured into the main tank. Since different batches of API wastewater may have differences in the types and concentrations of heterocyclic compounds and other pollutant contents, the stirring blade can stir and mix API wastewater from different periods or different sources, making the water quality of the API wastewater more uniform and reducing the impact on the subsequent biochemical treatment system. In addition, the secondary tank can share and store excess wastewater poured into the main tank, thereby ensuring that the subsequent biochemical treatment system can operate continuously and stably.

[0028] 2. The utility model uses a blower, a ventilation pipe and an air outlet. The blower supplies air to the stirring blade installed inside the main pool through the ventilation pipe. The supplied gas is discharged from the air outlet on the outer wall of the stirring blade and dissolved and mixed with the wastewater in the main pool, thereby increasing the dissolved oxygen content in the raw material wastewater, providing sufficient oxygen for aerobic microorganisms in the subsequent biochemical treatment process, and accelerating the degradation rate of pollutants such as heterocyclic compounds.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The following describes an embodiment of the present invention based on its overall structure.

[0036] A device for treating wastewater containing raw materials of heterocyclic compounds, such as Figure 1 - Figure 4 As shown, it includes a main pool 1 and a sub-pool 2. A motor 3 is installed at the bottom of the main pool 1. A rotating rod 31 is provided at the output end of the motor 3, and the rotating rod 31 passes through the bottom of the main pool 1. One end of the rotating rod 31 is connected to a turntable 51. A fixed column 5 is fixed on the top of the turntable 51, and a plurality of groups of stirring blades 52 are provided on the outer wall of the fixed column 5. A connecting pipe 42 is installed on the top of the fixed column 5. A support plate 11 is fixed on the top of the main pool 1, and a first blower 4 is installed at the bottom of the support plate 11. A first ventilation pipe 41 is provided at the bottom end of the first blower 4, and the first ventilation pipe 41 is movably connected to the connecting pipe 42, which solves the problem of the traditional process for treating pharmaceutical wastewater containing heterocyclic compounds. In order to solve the problem of needing to add a large number of bacterial strains to degrade organic pollutants in pharmaceutical wastewater, a stirring blade 52 is installed inside the main pool 1. The stirring blade 52 stirs the raw material pharmaceutical wastewater poured into the main pool 1. Since different batches of raw material pharmaceutical wastewater may differ in the type and concentration of heterocyclic compounds and other pollutant contents, the stirring blade 52 can stir and mix the raw material pharmaceutical wastewater from different periods or different sources to make the water quality of the raw material pharmaceutical wastewater more uniform and reduce the impact on the subsequent biochemical treatment system. In addition, the auxiliary pool 2 can share and store excess wastewater poured into the main pool 1, thereby ensuring that the subsequent biochemical treatment system can operate continuously and stably.

[0037] See also Figure 2 and Figure 4 The stirring blade 52 is tilted, and the middle part of the stirring blade 52 bulges outward. The stirring blade 52 is tilted, so that when the stirring blade 52 stirs the raw wastewater in the main pool 1, the resistance of the raw wastewater to the stirring blade 52 can be reduced.

[0038] See also Figure 4 A ventilation duct 43 and ventilation holes 44 are provided inside the fixed column 5, and the ventilation duct 43 is connected to the inside of the connecting pipe 42. The gas transmitted by the blower 4 is transmitted into the ventilation duct 43 inside the fixed column 5 through the ventilation duct 41, and then the ventilation duct 43 transmits the gas to multiple groups of ventilation holes 44, so that the gas can be discharged from the outlet hole 45 on the side of the stirring blade 52.

[0039] See also Figure 4 A plurality of air outlet holes 45 are provided on one side of the stirring blade 52, and the air outlet holes 45 are located on the back of the stirring blade 52. When the stirring blade 52 is stirring, the water pressure on the back of the stirring blade 52 is less than the water pressure on the front of the stirring blade 52. The air outlet holes 45 on the back of the stirring blade 52 discharge sufficient air, thereby increasing the oxygen content in the raw wastewater, which facilitates the degradation of compounds in the wastewater by microorganisms in the next process.

[0040] See also Figure 2 The outer wall of the main pool 1 is provided with a first water inlet pipe 12 and a first water outlet pipe 13, and the diameter of the first water inlet pipe 12 is larger than the diameter of the first water outlet pipe 13. The raw wastewater generated by the production of medicines enters the main pool 1 through the first water inlet pipe 12. The diameter of the first water outlet pipe 13 is smaller than the first water inlet pipe 12, so that the water discharge from the first water outlet pipe 13 is relatively stable, so that the subsequent programs can run slowly.

[0041] See also Figure 1 A sub-tank 2 is provided on one side of the main tank 1, and the bottom of the sub-tank 2 is higher than the bottom of the main tank 1. When a large amount of raw wastewater is poured into the main tank 1, the excess raw wastewater can flow into the sub-tank 2 through the second water inlet pipe 21. The sub-tank 2 shares the excess raw wastewater with the main tank 1. When there is less raw wastewater in the main tank 1, the wastewater in the sub-tank 2 is discharged into the main tank 1 to ensure that the main tank 1 can continuously discharge raw wastewater.

[0042] See also Figure 1 and Figure 3 A second water inlet pipe 21 is provided on one side of the main pool 1, and the second water inlet pipe 21 connects the interior of the main pool 1 and the auxiliary pool 2, and the second water inlet pipe 21 is higher than the first water inlet pipe 12. When the wastewater in the main pool 1 overflows the top of the first water inlet pipe 12, the wastewater flows into the auxiliary pool 2 through the second water inlet pipe 21, sharing the water volume for the main pool 1.

[0043] See also Figure 3 A second outlet pipe 22 is provided on one side of the main pool 1, and the second outlet pipe 22 is higher than the first outlet pipe 13. When there is less wastewater in the main pool 1, personnel open the valve 23 of the second outlet pipe 22, and the wastewater in the auxiliary pool 2 flows into the main pool 1 through the second outlet pipe 22. The second outlet pipe 22 is higher than the first outlet pipe 13, so that all the wastewater in the auxiliary pool 2 can flow into the main pool 1, providing wastewater for the main pool.

[0044] See also Figure 1 A valve 23 is installed in the middle of the second water outlet pipe 22, and the second water outlet pipe 22 is controlled by the valve 23 to drain water. When it is necessary to replenish wastewater from the auxiliary pool 2 to the main pool 1, personnel can control the valve 23 on the second water outlet pipe 22 to discharge the wastewater in the auxiliary pool 2 into the main pool 1.

[0045] See also Figure 4 The flux of the air outlet 45 is smaller than the flux of the ventilation hole 44, the wind pressure of the gas discharged from the air outlet 45 is greater than the water pressure inside the main pool 1, the amount of air transmitted by the ventilation hole 44 is greater than the amount of air discharged from the air outlet 45, so that the air outlet 45 on the stirring blade 52 can discharge air, and at the same time, the wind pressure of the gas discharged from the air outlet 45 is greater than the water pressure inside the main pool 1, preventing the raw material wastewater in the main pool 1 from flowing back into the air outlet 45.

[0046] The working principle of the utility model is as follows: first, the motor 3 and the blower 4 are turned on to operate, the motor 3 drives the stirring blade 52 to rotate and stir through the rotating rod 31, the blower 4 sends air to the inside of the main pool 1 through the ventilation pipe 41, and then the raw material drug wastewater is discharged into the main pool 1 from the first water inlet pipe 12, the stirring blade 52 stirs the various raw material drug wastewaters containing heterocyclic compounds poured into the main pool 1, so that the various raw material drug wastewaters containing heterocyclic compounds are mixed evenly, and at the same time, the blower sends air to the ventilation pipe 43 inside the stirring blade 52 through the ventilation pipe 41 and the connecting pipe 42, and the air then flows through the ventilation hole 44 It is discharged from the air outlet 45 on one side of the stirring blade 52. A part of the air discharged from the air outlet 45 dissolves in the raw material drug wastewater, thereby increasing the dissolved oxygen content in the raw material drug wastewater. The raw material drug wastewater inside the main pool 1 is discharged from the first outlet pipe, and then the next procedure is carried out. In addition, when there is too much raw material drug wastewater entering the main pool 1, the raw material drug wastewater will enter the auxiliary pool 2 from the second water inlet pipe 22. The excess raw material drug wastewater is stored in the auxiliary pool 2. When there is too little raw material drug wastewater in the main pool 1, the valve 24 is opened again, and the raw material wastewater in the auxiliary pool 2 enters the main pool 1 again through the second outlet pipe 23.
