Introduction to Wastewater

        Pharmaceutical intermediate wastewater is organic wastewater with complex water quality, high concentration, high chroma, and difficult to degrade. For pharmaceutical intermediate wastewater, it has the characteristics of high COD, high salinity, high chroma, complex composition, and poor biodegradability. It is currently used The treatment method is generally a combination of physical and chemical pretreatment + biochemical treatment. Through the physical and chemical process of pretreatment, the concentration of pollutants is greatly reduced, and the burden of subsequent biological treatment is reduced.

Source of wastewater

1、Biopharmaceuticals mainly refer to the production of antibiotic drugs. Wastewater mainly comes from processes such as filtration, fermentation, biological reactions, and extraction. The main components of wastewater are fermented mycelium, microbial metabolites, addition of some organic solvents, residual nutrients and residual antibiotics. Biopharmaceutical wastewater has the characteristics of high concentration of organic pollutants, high content of toxic and harmful substances, and poor biodegradability.

2、Chemical pharmacy mainly refers to the process of using chemical reactions to produce drugs or intermediates. Wastewater contains high organic matter content, many types of toxic substances, many intermediate residues, and high concentration of inorganic salts. Traditional Chinese medicine production wastewater mainly comes from processes such as washing, cooking and various preparations of medicinal materials.

3、The concentration of suspended solids in the production wastewater of traditional Chinese medicine is high, contains a lot of medicine residue, alkaloids, lignin and sugars, the color is generally relatively high, the concentration of organic matter is high and the changes are large, and there are many types of pollutants.

Wastewater hazards

        Difficult to degrade organic pollutants such as organic chlorides, high molecular polymers and polycyclic organic compounds. These non-degradable pollutants can remain in the water body for a long time after entering the water body, and most of them have strong toxicity, carcinogenic, teratogenic, and mutagenic effects. They are continuously accumulated and enriched through the food chain, and finally enter the animal or human body. Toxic or other hazards.

Wastewater characteristics

    1. High concentration of organic pollutants.

    2. There are many non-biodegradable substances, toxic and harmful substances.

    3. Large impact load. It is usually intermittently discharged, and temperature, pollutant concentration, and pH change greatly over time.

    4. High chroma and heavy peculiar smell.

    5. High concentration of suspended solids.
