[0027] The treatment agent supply tank 1 and the top end cover 3 can be fixed by snap-fit, bolt, or fastener to achieve a detachable connection between the treatment agent supply tank 1 and the top end cover 3.

[0028] According to the different treatment needs of pharmaceutical wastewater, treatment agent supply tanks 1 with different quantities of treatment agent holding chambers 2 are selected respectively, and different pharmaceutical wastewater treatment agents are stored in the treatment agent holding chambers 2.

[0029] The treatment agent supply tank 1 is fixed to an external drive device, which is existing technology and can drive the treatment agent supply tank 1 to move back and forth on the wastewater pool, so as to put the wastewater treatment agent into different positions in the wastewater pool.

[0030] like Figure 3 , Figure 4 and Figure 5 The top of the top end cap 3 has an annular cavity, and the bottom of the inner wall of the annular cavity has at least three feed holes 4. A rotating ring 5 is rotatably connected inside the annular cavity. A connecting hole 6 is provided on the rotating ring 5. The connecting hole 6 can rotate above different feed holes 4 as the rotating ring 5 rotates. A feed pipe 7 that can move up and down and rotates together with the rotating ring 5 is provided above the connecting hole 6. A feed hopper 8 is fixedly connected to the top of the feed pipe 7. The feed hopper 8 can guide the input pharmaceutical wastewater treatment agent, making it easier for the pharmaceutical wastewater treatment agent to enter the feed pipe 7.

[0031] like Figure 1 , Figure 4 and Figure 5 The number of feed holes 4 and the number of treatment agent storage chambers 2 are the same, and they are set one-to-one. Each treatment agent storage chamber 2 has a corresponding feed hole 4 above it.

[0032] like Figure 1 and Figure 2 The bottom of the treatment agent supply tank 1 is fixedly connected to a supply port 9, and the bottom of the treatment agent receiving chamber 2 is fixedly connected to a discharge pipe 10. A solenoid valve 11 is installed on the discharge pipe 10. The solenoid valve 11 is connected to an external power supply and is controlled by a switch located outside the treatment agent supply tank 1. Each solenoid valve 11 can be controlled independently.

[0033] like Figure 3 , Figure 4 and Figure 6 A vertical sleeve 12 is rotatably connected to the center of the top end cap 3. A rectangular cavity is opened inside the vertical sleeve 12. A return spring 13 is fixedly connected to the bottom of the inner wall of the rectangular cavity. A rectangular block 14 is fixedly connected to the top of the return spring 13. The rectangular block 14 fits against the inner wall of the rectangular cavity. A control lever 15 is fixedly connected to the top of the rectangular block 14. The top of the control lever 15 passes through the vertical sleeve 12 and is fixedly connected to a control handle 16, which can manually pull the control lever 15 and the rectangular block 14 upwards.

[0034] like Figure 3 , Figure 4 and Figure 6 A movable slot 17 is provided on one side of the vertical sleeve 12, and a movable connecting rod 18 is fixedly connected to one side of the rectangular block 14. One end of the movable connecting rod 18 passes through the movable slot 17 and is fixedly connected to the feed pipe 7, which is used to drive the feed pipe 7 to move up and down. The bottom of the feed pipe 7 can pass through the feed hole 4 and the connecting hole 6, and the movable connecting rod 18 can move up and down along the movable slot 17.

[0035] like Figure 1 and Figure 3Both sides of the vertical sleeve 12 are fixedly connected with drive rods 19. One end of the drive rod 19 is bent downward and fixedly connected to the rotating ring 5. It is used to drive the rotating ring 5 and the feed pipe 7 to rotate together. The drive rod 19 is used to fix the rotating ring 5 and the vertical sleeve 12. When the vertical sleeve 12 rotates, it can drive the rotating ring 5 and the feed pipe 7 to rotate together.

[0036] The working principle of the pharmaceutical wastewater treatment agent supply device provided by this utility model is as follows:

[0037] Taking the treatment of pharmaceutical wastewater with a slightly acidic pH (5–6) and containing a large amount of colloidal mycelium, dissolved organic matter (COD 8000–15000 mg / L), and phosphate (TP 50–100 mg / L) as an example:

[0038] First, lime, polyalumina and anionic PAM are stored in the three treatment agent storage chambers 2 respectively. By opening the corresponding solenoid valves 11, the different pharmaceutical wastewater treatment agents can be fed into the wastewater tank through the supply pipe 9.

[0039] First, add lime to react, mix, and let stand for 12 minutes: to ensure that the mycelium is completely broken down and phosphorus is completely precipitated (if less than 8 minutes, the phosphorus removal rate will be <70%).

[0040] Add polymerized alumina, mix, and let stand for 6 minutes; this quickly neutralizes the charge and prevents the flocs from breaking down due to prolonged stirring.

[0041] Add anionic PAM, mix, and let stand for 18 minutes to settle: high specific gravity flocs (containing Ca5(PO4)3OH precipitate) require sufficient settling time;

[0042] When it is necessary to add pharmaceutical wastewater treatment agent into the treatment agent container 2, pull the control handle 16 upward to move the rectangular block 14 upward. The rectangular block 14 moves the feed pipe 7 upward through the movable connecting rod 18. The bottom of the feed pipe 7 is disengaged from the feed hole 4. At this time, the control handle 16 can be rotated to rotate the vertical sleeve 12. The vertical sleeve 12 drives the rotating ring 5 to rotate through the drive connecting rod 19. At the same time, the vertical sleeve 12 drives the rectangular block 14 to rotate. The rectangular block 14 drives the feed pipe 7 to rotate around the vertical sleeve 12 through the movable connecting rod 18. When the feed pipe 7 rotates, it remains above the connecting hole 6.

[0043] Rotating ring 5 causes connecting hole 6 to align with different feed holes 4. Control handle 16 can be released. At this time, reset spring 13 retracts, rectangular block 14 moves down, and feed pipe 7 moves down accordingly. Different pharmaceutical wastewater treatment agents are added at feed hopper 8 and fed into different treatment agent holding chambers 2.

[0044] Compared with related technologies, the pharmaceutical wastewater treatment agent supply equipment provided by this utility model has the following beneficial effects:

[0045] This invention features multiple treatment agent storage chambers 2 inside the treatment agent supply tank 1. Different treatment agent storage chambers 2 are used to hold different pharmaceutical wastewater treatment agents, which allows for the supply of different pharmaceutical wastewater treatment agents to the wastewater at different times according to the treatment needs of the pharmaceutical wastewater. This avoids the conflict between the agents when they are added at the same time, thus preventing the wastewater treatment from being affected. At the same time, pulling up the control handle 16 can rotate the vertical sleeve 12, which drives the rotating ring 5 and the feed pipe 7 to rotate together. This aligns the feed pipe 7 with and passes through different feed holes 4, making it convenient to quickly replenish the pharmaceutical wastewater treatment agent into the different treatment agent storage chambers 2.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
