Pharmaceutical Antibiotics Wastewater Treatment

The pharmaceutical antibiotics wastewater treatment has the characteristics of complex composition, strong biological toxicity, and multiple difficult to degrade substances, and its treatment requires a multi-stage combination process.

In the wastewater treatment pharmaceutical industry, specialized pharmaceutical wastewater treatment systems are implemented to ensure compliance with strict environmental regulations. These systems integrate steps such as preliminary screening, biochemical treatment (including aerobic and anaerobic digestion), membrane filtration, advanced oxidation processes, and disinfection to reduce pollutant loads effectively.

Features of Pharmaceutical Antibiotics Wastewater

As a leading pharmaceutical wastewater treatment manufacturer in China, Molewater specializes in providing advanced and customized wastewater treatment solutions for the pharmaceutical industry.

Core processing flow

  • Physical interception: Grid filtration removes suspended solids (such as mycelium and medicinal residue).
  • Advanced oxidation
  • Fenton method: By decomposing antibiotics and recalcitrant organic compounds with hydroxyl radicals (OH), the biodegradability is improved (B/C value increases from 0.15 to 0.42).
  • Ozone oxidation: deep degradation of residual antibiotics.
  • Coagulation precipitation: Add PAC/PAM to remove colloids and some dissolved organic matter.
  • Evaporative crystallization (suitable for high salt wastewater): Desalination and recovery of solvents (such as when Cl >32000 mg/L).
  • Anaerobic stage
    UASB/EGSB reactor: efficiently degrades COD (removal rate>80%) and generates biogas for energy recovery.
  • Aerobic stage
    SBR/biological contact oxidation: enhances the removal of ammonia nitrogen and organic matter, adapting to water quality fluctuations.
    MBR membrane bioreactor: replaces traditional activated sludge process to achieve efficient solid-liquid separation (effluent COD<300 mg/L).
  • Membrane separation technology
    Nanofiltration (NF)/reverse osmosis (RO): deep desalination and removal of small molecule organic matter, with the resulting water reused for production (such as cooling water).
  • Adsorption and disinfection
    Activated carbon adsorption: removes trace residual antibiotics and chromaticity.
    UV disinfection: inactivate pathogens and drug-resistant bacteria to ensure sterile effluent
