Abstract:

After analyzing the status of emulsion wastewater and disposal of emulsion wastewater in cold rolling millsof iron and steel industry in China，an advanced constructed wetland process for the treatment of the cold rolling emulsion wastewater is put forward. Based on the analysis of the technical and economic feasibility of this process，the results show that this process is characterized by low investment， low operating costs and low management requirements. Moreover， using this process for treating cold rolling emulsion wastewater is feasible economically and technologically.

Key words: cold rolling emulsion wastewater, constructed wetland, advanced treatment
