Treatment of Pharmaceutical Wastewater

1. Characteristics:

The composition is complex, with a high content of organic substances, high toxicity, deep chroma, high salinity, and poor biodegradability.

2. Treatment Difficulties:

It contains antibiotics, making biochemical treatment rather difficult. The composition is complex, the quantity and quality of water are unstable, and the COD (Chemical Oxygen Demand) concentration is high.

3. Treatment Process:

Advanced oxidation + multi-stage biochemical treatment, anaerobic + aerobic treatment.

4. Solutions:

After applying air flotation for pretreatment to remove animal and vegetable oils in the wastewater, the combined anaerobic + aerobic treatment process is then applied to further remove pollutants in the wastewater so that it can be discharged up to the standards.

5. Discharge Standards:

The discharge standards in Table 2 of the Discharge Standard of Water Pollutants for Fermentation Pharmaceutical Industry (GB21903-2008).

The discharge standards in Table 2 of the Discharge Standard of Water Pollutants for Chemical Synthesis Pharmaceutical Industry (GB21904-2008).

The discharge standards in Table 2 of the Discharge Standard of Water Pollutants for Extraction Pharmaceutical Industry (GB21905-2008).

The discharge standards in Table 2 of the Discharge Standard of Water Pollutants for Traditional Chinese Medicine Pharmaceutical Industry (GB21906-2008).

The discharge standards in Table 2 of the Discharge Standard of Water Pollutants for Bioengineering Pharmaceutical Industry (GB21907-2008).

The discharge standards in Table 2 of the Discharge Standard of Water Pollutants for Mixed Preparation Pharmaceutical Industry (GB21908-2008).
