Iron-carbon micro-electrolysis method for treating wastewater containing inorganic and organic matter

The invention belongs to the technical field of wastewater treatment, and discloses an iron-carbon micro-electrolysis method for treating wastewater containing inorganic and organic matter. The problem that in the prior art, inorganic and organic mercury removal and organic matter degradation cannot be achieved at the same time is solved. The method includes the following steps of 1 pretreatment, wherein oil in the organic wastewater is removed to be lower than 70 mg/L through the unoiling and dewaxing pretreatment process, and the pH value is adjusted to be 3-5; 2 iron-carbon micro-electrolysis treatment process, wherein the pretreated wastewater enters the upper portion of an iron-carbon micro-electrolysis device, and heavy metal in the wastewater is removed through an iron-carbon filler layer in the iron-carbon micro-electrolysis device; organic matter and metal ions are adsorbed through the adsorption action of the iron-carbon filler layer; organic mercury is degraded into inorganic mercury through microe
