Description

technical field [0001] The invention relates to the technical field of iron-carbon micro-electrolysis packing, in particular to a high-efficiency heterogeneous catalytic iron-carbon micro-electrolysis packing and a preparation method thereof. Background technique [0002] Micro-electrolysis technology, also known as internal electrolysis, iron reduction, iron-carbon method, zero-valent iron method, etc., is an ideal process for treating high-concentration organic wastewater. It does not need to be powered on. It uses the wastewater itself as the electrolyte, the iron filled in the acidic wastewater as the anode, and the carbon as the cathode. It generates a 1.2V potential difference by itself, forming tens of thousands of tiny batteries to electrolyze the wastewater to achieve the degradation of wastewater. The purpose of organic pollutants. [0003] The materials used in the existing iron-carbon bed micro-electrolytic packing are iron shavings (with a carbon content of 8-1...
