What are the principles and characteristics of micro-electrolysis iron-carbon filler?

Micro-electrolysis technology is an ideal process for treating high concentration organic wastewater at present, also known as internal electrolysis. In the absence of power supply, it electrolyzes wastewater by using the potential difference of 1.2V generated by micro-electrolysis materials filled in wastewater, thus achieving the purpose of degrading organic pollutants.

Principle of micro-electrolysis: When the filler is immersed in the electrolyte solution, numerous micro-battery systems will be formed due to the electrode potential difference of 1.2V between Fe and C, and an electric field will be formed in its action space, and a large amount of Fe2 will be generated through anode reaction.

Enters the wastewater, and then is oxidized into Fe3.

Forming a flocculant with high adsorption and flocculation activity. Cathode reaction produces a lot of new ecology [H] and [O]. Under acidic conditions, these active components can undergo redox reaction with various components in wastewater, leading to chain-breaking degradation of organic macromolecules, thus eliminating the chromaticity of organic substances, especially printing and dyeing wastewater, and improving the biodegradability of wastewater. Its working principle is based on the interaction of electrochemistry, redox, physical adsorption and flocculation precipitation to treat wastewater.

Advantages: wide application range, good treatment effect, low cost, convenient operation and maintenance, no need to consume power resources, fast reaction speed, stable treatment effect, no secondary pollution, improved biodegradability of wastewater, chemical precipitation to remove phosphorus, reduction to remove heavy metals, pretreatment of biological treatment, which is beneficial to sludge precipitation and biological biofilm formation.

Pingxiang Bhutto environmental protection reminds you that the problems that need to be paid attention to in the use of TPFC micro-electrolysis filler are as follows:

1, micro-electrolysis water treatment filler should be waterproof and anticorrosive before use. Once in operation, it should be protected from water at all times, and it should not be exposed to the air for a long time, so as not to be oxidized in the air and affect its use.

2. Proper aeration should be paid attention to during the operation of micro-electrolysis system, and repeated aeration for a long time is not allowed.

3. Micro-electrolysis system should not run under alkaline conditions for a long time;

4. The suitable PH range for micro-electrolysis operation is about 2-4.

I hope I can help you!
