Description

Technical field [0001] The invention belongs to the field of water treatment, and relates to an organic wastewater treatment device, in particular to an iron-carbon micro-electrolysis coupled electrochemical water treatment device and a treatment method. Background technique [0002] At present, iron-carbon micro-electrolysis is widely used in the field of organic wastewater treatment. Iron-carbon micro-electrolysis uses the potential difference between iron and carbon to degrade organic matter, so as to achieve the effect of water treatment. [0003] However, most of the existing methods directly pass the organic wastewater into the iron-carbon micro-electrolysis cell. Since the potential difference of the iron-carbon micro-electrolysis is small, the degradation of the organic wastewater is relatively slow. In addition, iron-carbon micro-electrolytic fillers are easy to precipitate iron and carbon, mainly with Fe 3+ The ionic form and C elemental form exist in wastewater, which w...

[0003] However, most of the existing methods directly pass the organic wastewater into the iron-carbon micro-electrolysis cell. Since the potential difference of the iron-carbon micro-electrolysis is small, the degradation of the organic wastewater is relatively slow.

In addition, iron-carbon micro-electrolytic fillers are easy to precipitate iron and carbon, mainly Fe 3+ The ionic form and C elemental form exist in wastewater, which will cause secondary pollution of water quality, which is not conducive to environmental protection requirements
