Chemical Wastewater Treatment
Technical Advantages:

Stabilized Wastewater Quality: To address the complexity and variability of chemical wastewater, the collection tank employs a partitioned distribution system to stabilize water quality and quantity.

Targeted Pre-treatment: Different types of chemical wastewater are treated using targeted and efficient physicochemical pre-treatment methods to remove or reduce specific pollutants, thereby decreasing the toxicity that could impact downstream systems and enhancing overall stability.

Effective Particle Removal: High-efficiency flotation equipment is utilized to further remove suspended particles and colloidal pollutants.

Homogenization for Stability: Homogenization ensures the stability of wastewater and replenishes essential elements for the biological treatment system.

Uniform Inlet Distribution: The inlet distributor at the bottom of the high-efficiency anaerobic tower achieves uniform water distribution, with a reasonable upward flow rate that effectively suspends granular sludge and efficiently removes COD from the wastewater.

Salt Tolerance Enhancement: Given the high salt content of chemical wastewater, salt-tolerant bacteria are added to the activated sludge in the aerobic tank to enhance the system's salt tolerance.

Integration of Membrane Technology: The combination of activated sludge and membrane treatment processes enables wastewater reuse.
