- Abstract:
- Taking the comprehensive wastewater treatment and upgrading project of a steelworks in Hubei Province as an example, the reasons for the wastewater discharge exceeding the standard are analyzed. According to the water quality characteristics, the upgrading process of grid, oil-isolation grit chamber, horizontal sedimentation tank, contact oxidation tank, high efficiency sedimentation tank, V-type filter, ultrafiltration, and two-stage reverse osmosis is selected. After the advanced treatment of wastewater, the consumption of new water is significantly reduced, the effluent quality meets the requirements of reclaimed water in the Code for Design of Industrial Recirculating Cooling Water Treatment (GB 50050-2017), and desalted water can be provided. Practice shows that the selection of process route is reasonable and the operation is stable and reliable, which can provide reference for upgrading and reconstruction of comprehensive wastewater in similar steelworks.
