Pharmaceutical wastewater treatment system and process

Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to a pharmaceutical wastewater treatment system and a pharmaceutical wastewater treatment process. The pharmaceutical wastewater treatment system comprises a wastewater regulating tank, a primary flocculation tank, a primary sedimentation tank, a lifting tank, an anaerobic tank, an aerobic tank, a secondary flocculation tank and a final sedimentation tank which are connected in sequence; and the lifting tank is connected with double-electrode-layer equipment. The pharmaceutical wastewater is sequentially subjected to pH value regulation by the wastewater regulating tank, flocculation by the primary flocculation tank and solid-liquid separation by the primary sedimentation tank, the separated waste liquid is introduced into the lifting tank, the waste liquid stored in the lifting tank is subjected to high-voltage pulse electro-catalysis treatment by the double-electrode-layer equipment, the treated waste liquid is sequentially subjected to biochemical treatment by the anaerobic tank and the aerobic tank, and flocculent precipitation and solid-liquid separation are conducted through the secondary flocculation tank and the final sedimentation tank to complete treatment of the pharmaceutical wastewater. The pharmaceutical wastewater can meet the discharge requirement after being treated, and the treatment system and process have good stability on pharmaceutical wastewater treatment.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a pharmaceutical wastewater treatment system and process. Background technique [0002] Mixed preparation pharmacy refers to the process of forming various dosage forms of drugs through mixing, processing and preparation of active ingredients and excipients.

AI Technical Summary

Problems solved by technology

The drug varieties produced by the pharmaceutical company where the inventor works include anti-bacteria, anti-virus, analgesic and anti-inflammatory, anti-fungal, skin medicine, blood lipid and blood sugar lowering, cardiovascular system, digestive system, anti-mental disorder, anti-allergic, nutritional There are hundreds of raw and auxiliary materials and finished products, and the waste water has the characteristics of high concentration of organic matter, high chroma, substances that are difficult to degrade and toxic to microorganisms, complex water components, and poor biodegradability.

There are antibiotics and high-concentration organic matter left in the wastewater. Due to the strong inhibitory effect of residual antibiotics on microorganisms, aerobic bacteria are poisoned, and aerobic treatment is difficult, while anaerobic treatment of high-concentration organic matter is difficult to meet the effluent standard. Therefore, traditional biological treatment methods are very difficult. It is difficult to achieve the expected processing effect

Conventional physical and chemical methods + traditional biochemical methods alone cannot meet the discharge standards. Effective pretreatment of residual antibiotics and high-concentration organic matter is required to improve the biodegradability of wastewater, thereby reducing the difficulty of subsequent biochemical treatment.
