Industrial Wastewater Pretreatment
The sewage treatment plant in the chemical industrial park receives wastewater from various upstream chemical enterprises. The wastewater has a complex composition and high color levels, with poor biodegradability, making biological treatment difficult. Additionally, the wastewater has already undergone primary pretreatment and secondary biological treatment at the upstream chemical enterprises, leaving behind mostly stubborn pollutants that are difficult to biodegrade, further complicating the biological degradation process. The diverse water quality poses a significant impact on the sewage plant's treatment system, and the capacity of the plant's biological treatment unit is limited, making it challenging to meet discharge standards using biological methods alone.
