API pharmaceuticals

Active Pharmaceutical Ingredients (APIs) are the basis of the active ingredients of pharmaceuticals. Their production process often involves complex chemical reactions and separation and purification steps, generating large amounts of wastewater. These wastewaters typically have high concentrations of organic matter (measured by chemical oxygen demand (COD) and total organic carbon (TOC), contain structurally stable and difficult-to-biodegrade API molecules themselves and their production intermediates, and have high chroma, high salt content, and exhibit significant biological toxicity, resulting in generally poor biodegradability (BOD5/CODcr ratio).

Ultraviolet light/hydrogen peroxide (UV/H₂O₂) combined technology utilizes ultraviolet light of a specific wavelength to irradiate hydrogen peroxide (H₂O₂), triggering the decomposition of H₂O₂ molecules to produce highly reactive hydroxyl radicals (OH). The strong oxidizing properties and non-selectivity of OH radicals enable them to effectively destroy the chemical structure of API molecules and their complex intermediates, gradually breaking them down into small molecules and eventually mineralizing them into CO2, H₂O, and inorganic salts, thereby degrading pollutants.

UV/H2O2 technology demonstrates excellent degradation of a variety of typical APIs, including antibiotics, hormones, phenolic compounds, nitrogen-containing heterocyclic compounds, and some organic solvents (such as dichloromethane (DCM)).

The process flow for UV/H₂O₂ treatment of API pharmaceutical wastewater is as follows:

UV Hydrogen Peroxide Advanced Oxidation Process: Pretreatment, UV/H₂O₂ Reaction, and Post-treatment

· Pretreatment Stage

    Grids and Screens: Remove large suspended and floating solids.

    Equalization Tank: Evenly distributes water volume and quality, and buffers pH fluctuations.

    Coagulation/Sedimentation/Flotation: Removes fine particles and improves UV transmittance.

· UV/H₂O₂ Reaction Unit

    Reactor: Typically constructed of stainless steel or other materials with good UV and H₂O₂ resistance, the reactor is equipped with a UV lamp (either a low-pressure, high-intensity mercury lamp or a medium-pressure mercury lamp).

    H₂O₂ Dosing and Control: Hydrogen peroxide solution is precisely dosed to the reactor inlet or reaction zone via a metering pump.

·Subsequent Treatment Stages

    H₂O₂ Removal

    pH Neutralization and Biological Treatment

    Advanced Treatment

 光解

光解

紫外光解通常是指利用紫外线（UV）照射来分解物质（尤其是污染物）的技术。

某些物质（特别是有机污染物）的分子键能被特定波长的紫外线（通常是短波长的 UV-C，如 254 nm）直接打断，发生裂解反应，分解成更小的分子、自由基或最终矿化为 CO₂ 和 H₂O，这被称为直接光解。主要可用于超纯水去除TOC、纯化水RO膜前余氯脱除及消毒、游泳池与水景中氯铵分解及消毒。
