Iron-carbon micro-electrolysis filler and preparation method thereof

Abstract

The invention relates to an iron-carbon micro-electrolysis filler; the iron-carbon micro-electrolysis filler takes activated sludge as an adhesive, and is prepared by the following steps: 1) manuallycracking whole section of jujube charcoal into small particles, putting the small particles into a powder mill, grinding into powder, and sieving the powder with a 30-mesh sieve to obtain carbon powder; 2) taking waste iron scraps generated in an iron product machining process as iron powder; 3) taking residual sludge as an adhesive; 4) putting the charcoal powder and the iron powder into a container according to a ratio, and fully and uniformly mixing; 5), adding activated sludge into the mixed charcoal powder and iron powder according to a certain ratio and uniformly stirring; 6), putting the mixed material into a mold, beating for several times, and demolding; and 7), drying after standing in a natural state for 24 h, and thus obtaining the iron-carbon filler. The iron-carbon filler hasthe advantages of simple process, convenient preparation, low cost, energy saving and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of water treatment fillers, and in particular relates to an iron-carbon micro-electrolytic filler and a preparation method thereof. Background technique [0002] Iron-carbon filler, also known as micro-electrolytic filler, iron-carbon micro-electrolytic filler, and internal electrolytic filler, is one of the important conditions for micro-electrolysis technology to treat wastewater. Electrochemical catalytic oxidation of iron-carbon internal electrolytic filler is used to remove phosphorus from wastewater. At present, the requirements for micro-electrolysis electrode materials are getting higher and higher in the process of water treatment, and the fillers such as iron carbon on the market can no longer meet people's requirements for micro-electrolysis fillers. The iron carbon made of iron filings and iron shavings is called the first generation of iron carbon, which is prone to problems such as agglomeratio...

AI Technical Summary

Problems solved by technology

At present, the requirements for micro-electrolysis electrode materials are getting higher and higher in the water treatment process, and the fillers such as iron carbon on the market can no longer meet people's requirements for micro-electrolysis fillers.

The iron carbon made of iron filings and iron shavings is called the first generation of iron carbon, which is prone to problems such as agglomeration of iron filings and clogging of the reaction bed during the water treatment process of this iron carbon.

Iron-carbon fixed bed and fluidized bed are called the second-generation iron-carbon. The iron-carbon water treatment process occupies a large area, high maintenance costs, and iron is easy to corrode and passivate.

The iron-carbon sintered with clay at high temperature is called the third-generation iron-carbon. Although it solves the problems of iron filings agglomeration and passivation, the reflection effect is reduced.
