Background of the Project:
Vanden (Changzhou) New Metal Material Technology Co., Ltd. specializes in the production of steel cords for the tires, precision chemicals, precision machinery and photovoltaic industry. The wastewater produced is mainly pickling and degreasing wastewater.
Jintan, Changzhou, Jiangsu Province.
Wastewater composition is complicated. Including waste acid, spent degreasing solution, process flushing water, Zn, Cu waste water.
1. cleaning and diverting, multi-stage micro-flocculation and sedimentation technology, the effluent metal ion content is less than 0.5mg/L;
2. Heterogeneous catalytic oxidation treatment of degreased waste liquid, and the effluent reaches the discharge level of Taihu Lake Basin;
3. system automation, intelligent big data management.
