Industrial wastewater treatment--titanium dioxide wastewater Industrial wastewater treatment--pharmaceutical and food wastewater

The production process of titanium dioxide can be divided into sulfuric acid method and The characteristics of pharmaceutical and food industry wastewater are complex composition,
chlorination method. The sulfuric acid method produces a huge amount of wastewater, and the high organic content, high toxicity, deep color, high salt content, and poor biochemical properties.
chlorination method wastewater contains difficult to treat components such as ferric chloride, The water quality and quantity fluctuate greatly, making it difficult to treat industrial wastewater.
resulting in high treatment costs. Traditional lime neutralization and other technologies cannot The main application points include: meeting discharge standards, upgrading standards, reclaimed
achieve the recovery of valuable substances such as water resources, sulfuric acid, titanium dioxide, water reuse, zero discharge, and resource utilization.

Technical advantages Technical advantages

· To achieve stable and standardized treatment of high salt and high COD wastewater;
· Inorganic ceramic materials: Long service life, and not affected by high acid and alkali, high
· The water quality of the produced water is stable, achieving wastewater reuse.
temperature, high pressure and other working conditions;
· High water quality: SS ≤ lppm, turbidity ≤ 0.5NTU, stable water quality;
· Save occupation: Replaced the sedimentation tank, high integration, small construction area;
· Simple operation: Short technical process, few control points, and can achieve DCS automatic control;
· Circular economy: Titanium dioxide powder is fully recovered, and the produced water is recycled,
especially by combining the chlorination titanium dioxide process with the caustic soda process to form
a circular environmental protection and energy-saving industrial chain.
