Reverse electrodialysis of nitrogen compounds - electrochemical wastewater treatment process

摘要

[MEANS FOR SOLVING PROBLEMS] The steps of separated into a concentrated water and produced water through a reverse electrodialysis apparatus inflow water containing nitrogen compounds, and reverse electrical, including the decomposing stage the removal target substance of wastewater in an electrochemical wastewater treatment equipment concentrated water to provide a wastewater treatment method using a mixing step of electrochemical wastewater treatment - dialysis. It also provides a wastewater treatment method decomposing the removal target substance in wastewater in electrochemical wastewater treatment system alone inflow water containing nitrogen compounds. As a result, the produced water is discharged from the reverse electrodialysis device is reusable as industrial water, concentrated water, simultaneous processing and T-N and non-biodegradable COD through an electrochemical wastewater treatment equipment then, to ensure the reliability and stability of wastewater treatment equipment. In particular, from the waste water that occur in industrial facilities and power plants to use as a pH adjusting agent ethanol amine, can be removed efficiently and T-N and non-biodegradable COD induced by ETA. The reverse electrodialysis - connection not only is easy to waste water treatment process of an existing, electrochemical wastewater treatment process, can be stable processing an efficient T-N-containing wastewater and non-biodegradable COD Yes, it is possible to respond actively to environmental standards in the future, such as total volume control is strengthened.
