The Metallurgical Industry Wastewater Treatment System is a comprehensive solution designed for steel, copper, aluminum, and other metal processing industries. It integrates physical, chemical, and biological treatment technologies to efficiently treat complex wastewater containing oil, copper, cyanide, and other contaminants. With its compact and integrated design, the system ensures effluent meets national Class I discharge standards, reduces environmental pollution, saves space, and can be customized to handle specific wastewater compositions.
The system employs targeted treatment processes depending on wastewater type:
·
Oil-Containing Wastewater:
Floating oil is removed via an oil separation process, followed by micro-electrolysis and flocculation-sedimentation pre-treatment to break down organic pollutants and remove suspended solids. Anaerobic biochemical treatment then reduces COD and BOD, and a membrane bioreactor (MBR) combines membrane filtration with biological degradation to achieve high-quality effluent meeting Class I discharge standards.
·
·
Cyanide-Containing Wastewater:
Cyanide is removed through acidification and stripping, then oxidized to non-toxic cyanate precipitates. Residual pollutants are further removed by filtration and adsorption processes.
·
·
Copper-Containing Wastewater:
Copper and other heavy metals are precipitated via chemical precipitation and subsequently filtered to remove suspended solids, ensuring clean discharge.
·
The system can flexibly combine physical, chemical, and biological processes, adopting optimal treatment paths for different pollutants to achieve efficient and reliable wastewater purification.
