Abstract

The invention discloses composite micro-electrolysis filler as well as a preparation method and application thereof, and belongs to the field of wastewater treatment. The micro-electrolysis filler is prepared from the raw materials such as iron powder, charcoal active powder, a dispersing agent, a binding agent, a catalyst and the like. By applying the micro-electrolysis filler into the wastewater treatment, the problem that traditional micro-electrolysis filler is likely to harden and passivate can be solved, the biodegradability of wastewater can be obviously improved, and the wastewater processing efficiency is improved.

Description

Technical field: [0001] The invention relates to a micro-electrolytic filler and its preparation method and application, in particular to a composite micro-electrolytic filler and its preparation method and application, belonging to the field of wastewater treatment. Background technique: [0002] Micro-electrolysis technology is mainly used in pretreatment and advanced treatment of industrial wastewater and domestic sewage. It has fast reaction rate, simple operation and management, and low operating cost. It is the first choice for many sewage treatment plants. Its main working principle is to use the micro-electrolytic material filled in the wastewater to generate a potential difference, and to electrolyze the wastewater to decompose the complex macromolecular substances into small molecular substances, improve the biodegradability of the wastewater, and achieve the purpose of degrading pollutants. Purpose. [0003] Micro-electrolysis can significantly reduce the chroma ...
