Description

TECHNICAL FIELD

[0001] The utility model relates to wastewater treatment technical field, concretely is a pharmaceutical wastewater treatment device. BACKGROUND

[0002] Pharmaceutical wastewater refers to the wastewater generated in the production process of pharmaceutical industry, which has the characteristics of high concentration of organic matter, complex composition and biologically refractory substances, and direct discharge of pharmaceutical wastewater will cause serious pollution to the environment, so it is of great significance to treat pharmaceutical wastewater. The pharmaceutical wastewater treatment generally uses a filter screen to filter out the solid residues in the wastewater, then uses activated carbon to remove pollutants in the wastewater, and then adjusts the pH value of the wastewater by adding chemical reagents.

[0003] The Chinese patent with publication number CN208617527U discloses a pharmaceutical wastewater treatment device, which comprises a first treatment tank and a second treatment tank, a water inlet pipe is connected to the first treatment tank, hooks are arranged on the inner wall of the first treatment tank, a first filter screen is connected to the hooks through a steel wire rope, an activated carbon layer is arranged below the first filter screen, a feeding chute is arranged on the side wall of the first treatment tank, a pH detector is arranged in the first treatment tank, a water pump is arranged in the first treatment tank, the water pump is connected to the second treatment tank through a connecting pipe, a motor is arranged on the top of the second treatment tank, a rotating shaft is connected to the motor, a stirring rod is connected to the rotating shaft, a drain is arranged on the inner wall of the middle part of the second treatment tank, an electromagnetic control valve is arranged on the drain, a second filter screen is arranged below the drain, and a drain pipe is arranged at the bottom of the second treatment tank.

[0004] The above-mentioned wastewater treatment device can adjust the pH value of the wastewater by adding acidic or alkaline adjusting agents through the feeding chute, but the adjusting agents are added concentratedly, which makes it difficult for the adjusting agents to mix uniformly with the wastewater, affecting the treatment effect. Although the first filter screen is arranged to filter the waste residues, the first filter screen needs to be taken out through the steel wire rope and the hooks for cleaning, which is troublesome. Although the activated carbon layer is arranged to adsorb some harmful substances in the wastewater, the activated carbon layer is single and has a short contact time with the wastewater, so the adsorption is not complete, and therefore improvement is needed.
