Problems solved by technology

[0007] d. The filler of iron-carbon micro-electrolysis needs to replenish the iron consumed by the reaction in time, which further increases the operating cost and labor cost
[0008] e. The irrationality of the structure of the micro-electrolysis device. When the traditional micro-electrolysis filler reaction device treats wastewater, it is a sequential batch treatment. After the wastewater enters the micro-electrolysis device, it reacts. After the reaction time is over, the wastewater is discharged, and then the next step is carried out. Batch inflow and outflow reactions, unable to continuously treat wastewater
In engineering applications, multiple separate micro-electrolysis reaction devices need to be installed, which increases investment and troublesome operation and management

Abstract

The invention discloses a processing production and use method of a microelectrolysis filler for wastewater treatment. The prepared microelectrolysis filler consists of the following raw materials: iron powder, inert carbon powder, a binding agent, a surfactant A10, and trace amounts of molybdenum powder and chromium powder. The microelectrolysis filler disclosed by the invention can solve the problems of hardening, passivation, activation and difficulty in replacement of the filler adopted by the conventional microelectrolysis sewage treatment process.

Description

technical field [0001] The invention relates to a method for processing, producing and using micro-electrolytic fillers for waste water treatment, which belongs to the field of environmental protection, and in particular relates to the treatment of industrially polluted waste water. Background technique [0002] Iron-carbon micro-electrolysis technology is a new technology that has been widely studied and applied in the past ten years. It has a wide range of applications, has no selectivity for pollutants, and has a good removal effect. It can be applied to the treatment of various wastewater. [0003] Micro-electrolysis technology has carried out a large number of experimental studies on printing and dyeing wastewater, papermaking wastewater, coking wastewater, explosives wastewater, pharmaceutical wastewater, oily wastewater, landfill leachate, high-salinity wastewater, etc. Micro-electrolysis technology has a certain degree of COD removal , while greatly improving the bio...
