煤化工废水处理工艺的参数优化

Key Points

• The aim is to optimize key parameters in the combined wastewater treatment processes for coal chemical industry.
• Utilized single-factor optimization for initial parameter screening.
• Employed multi-factor orthogonal experiments to assess interactions among parameters.
• Applied response surface methodology to describe non-linear relationships in complex processes.
• Identified optimal pH values and reaction times for pre-treatment stage.
• Determined ideal sludge concentrations and dissolved oxygen levels for biological treatment.
• Optimized operating pressures and pH for advanced oxidation processes.
