What are the advanced sewage treatment technologies today?

The iron-carbon microelectrolysis method is a comprehensive effect of electrochemical REDOX, electrochemical electroconcentration of floc, condensation of electrochemical reaction products, adsorption of new floc and bed filtration, among which REDOX, electric adhesion and condensation are the main effects. When the iron filings are immersed in the wastewater containing a large number of electrolytes, countless tiny galvanic cells are formed. After the coke is added to the iron filings, the iron filings contact with the coke particles to further form large galvanic cells, so that the iron filings are corroded on the basis of micro galvanic cells and corroded by large galvanic cells, thus speeding up the electrochemical reaction. This method has many advantages, such as wide application range, good treatment effect, long service life, low cost and easy operation and maintenance, and uses waste iron filings as raw materials, and does not need to consume power resources, and has the significance of "treating waste with waste". At present, iron-carbon micro-electrolysis technology has been widely used in dyeing, pesticide/pharmaceutical, heavy metal, petrochemical and oil waste water and landfill leachate treatment, and has achieved good results. All kinds of industrial sewage treatment equipment.
