Working principle: When in use, the pharmaceutical wastewater is injected into the water inlet frame 11. After preliminary filtration through the secondary filter 20, the pharmaceutical wastewater enters the water inlet conduit 13 through the water outlet 19, and enters the purification tank 1 along the water inlet conduit 13. After being filtered again by the primary filter 9, it reaches the position of the mixing drum 17. The mesh diameter of the primary filter 9 is smaller than the mesh diameter of the secondary filter 20. Then, activated carbon adsorbent is added to the purification tank 1, and the mixing drum 17 is driven by the driving motor 2 to rotate, so that the pollutants are fully mixed with the adsorbent. The pollutants adhere to the adsorbent and sink to form precipitation due to gravity, thereby achieving the purpose of purifying the wastewater. After the purified pharmaceutical wastewater is pumped by the water supply pump 3, it enters the interior of the discharge temporary storage box 5 through the guide pipe 4. The staff uses a water quality detector to detect whether the water quality inside the discharge temporary storage box 5 meets the discharge standard. If it does not meet the standard, the water is discharged to the interior of the purification tank 1 through the circulation discharge pipe 7 and the adsorbent is continued to be added for secondary purification to achieve the purpose of circulation purification until the water quality in the discharge temporary storage box 5 is qualified. The pharmaceutical wastewater is discharged through the discharge pipe 10.
