Abstract

The invention discloses a method for producing an iron carbon micro-electrolysis filler from nonferrous metal waste ore slag, which comprises the following steps: grinding copper ore slag and lignite, and passing through a 100-120-mesh sieve; carrying out magnetic separation to remove impurity silicon dioxide powder; adding assistants; injecting into a squeeze film to obtain strips, and cutting into cylindrical blanks; drying; heating the blanks; and carrying out compression molding. The product disclosed by the invention has the characteristics of integrated iron carbon, large specific area, light specific gravity, strong activity, high current density, high efficiency for treating various types of sewage, and the like, and has the catalyst / micropore-fused alloy structure. The high-activity nonferrous metals, such as Cu and the like, contained in the novel product change the phenomena of filler passivation, hardening and the like in the old product operational process, and ensure the long sustained action period of the micro-electrolysis reaction process.

Description

technical field [0001] The invention mainly relates to a method for iron-carbon micro-electrolysis packing, in particular to a method for producing iron-carbon micro-electrolysis packing by using nonferrous metal waste slag. Background technique [0002] Low-cost and high-efficiency implementation of high-concentration and difficult wastewater treatment processes and technologies is not only an urgent need for environmental protection engineering applications, but also an urgent need for the entire society to solve water environmental pollution. In recent years, studies have found that using iron and carbon as the main raw materials of primary batteries has excellent effects on the reduction and decolorization of organic pollutants, such as heavy metals and printing and dyeing wastewater. Especially the divalent iron ions in the water after the iron-carbon micro-electrolysis treatment and the cheap oxidant H on the market 2 o 2 The combined FENTON reagent has oxidation cha...
