The pharmaceutical industry plays a crucial role in my country's economy. However, it is also recognized as a highly polluting sector, particularly due to its significant impact on water environments. Globally, concerns regarding the environmental consequences of pharmaceutical industry wastewater have gained attention. In fact, the pharmaceutical industry is among the ten key industries targeted for special rectification under the "Ten Water Regulations."
Pharmaceutical wastewater is classified as a challenging type of industrial wastewater. It exhibits varying compositions, complex components, substantial pollutant loads, high chemical oxygen demand (COD), numerous refractory substances, and strong toxicity due to different drugs and production processes.
In response to these concerns, the Ministry of Ecology and Environment and the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China released water pollutant discharge standards specifically for the pharmaceutical industry, focusing on mixed preparations.
Addressing wastewater discharge from pharmaceutical companies has become a priority in pollution prevention and control efforts. Environmental Impact Assessments (EIA) are conducted to determine appropriate and effective wastewater treatment processes based on factors such as production procedures, wastewater types, and the quality and quantity of wastewater.
Key Characteristics of Pharmaceutical Wastewater:
High pollutant load: Pharmaceutical wastewater primarily contains reactants, solvents, products, and by-products, resulting in a COD range of tens of thousands to hundreds of thousands. The biochemical properties of this wastewater are challenging, making conventional biochemical treatment methods difficult to implement.
High toxicity: Pharmaceutical wastewater contains pollutants such as antibiotics, DMF, THF, acetone, chloroform, and benzene, which inhibit the activity of microorganisms.
High salinity: The wastewater originates from raw materials and by-products of synthesis reactions, leading to elevated levels of Cl- and SO42-. This mixed salt composition poses challenges, including dehydration and inactivation, or even the death of microbial cells. It exceeds the limits of conventional biochemical treatment, increases wastewater density, accelerates sludge floating, and causes equipment corrosion.
Complexity: The diverse range of pharmaceutical products results in significant variations in the water quality of wastewater, further complicating treatment processes.
In the medical sector, aeration heads are available in two types
Tubular and spherical. The spherical type is constructed by welding porous titanium spherical surfaces and titanium plates. It can be directly connected to pipe threads, and various interface connection methods can be customized to meet specific customer requirements. Spherical aeration heads find wide applications in drinking water treatment, ozone sterilization, reclaimed water reuse, sewage treatment aeration tanks, and fermentation oxygenation.
