Electrocatalytic equipment for COD removal supports customized wastewater treatment

Electrocatalytic oxidation equipment is an efficient and practical treatment device developed for the current problems of high concentration, difficult to degrade wastewater and biochemical non-compliance. It is mainly used for the treatment of high concentration, high salt, high COD wastewater and the deep treatment of biochemical wastewater. The device utilizes an external power source to conduct an electrochemical reaction between the composite electrode plate and the wastewater in the reactor.

Under the action of an external electric field, the device introduces the treated sewage or liquid into the electrolytic cell. Under the action of current, active groups such as hydroxyl radicals are generated on the surface of the electrode material to oxidize organic matter in the water, decomposing it into carbon dioxide, water, small molecule organic matter, etc., which can reduce COD, ammonia nitrogen, chromaticity, and improve biodegradability in water.

Electrocatalytic oxidation can be applied to the modification and advanced treatment of recalcitrant organic wastewater, and is suitable for advanced treatment of petrochemicals, organic fine chemicals, chemical synthesis pharmaceuticals, pesticides, and intermediates.

Product advantages:

1. Using catalytic anode, it has strong ability to oxidize organic compounds and fast reaction rate;

2. Electrocatalytic oxidation can not only remove COD and chromaticity, but also efficiently remove ammonia nitrogen from wastewater.

3. Adding catalysts to special wastewater can improve conductivity, enhance electrolysis efficiency, and improve treatment efficiency;

4. The equipment adopts an integrated design, which is easy to install, simple to operate, and flexible;

5. The electrocatalytic oxidation electrode is a non soluble coated electrode with minimal electrode loss during use and a long service life;

6. The equipment greatly improves the current efficiency, unit time and space efficiency, sewage treatment efficiency, and organic matter degradation effect, and also has good adaptability to wastewater with low conductivity.

Technical features:

1. No secondary pollution;

2. The current and voltage of the power supply can be adjusted at any time according to the incoming water quality, with strong controllability;

3. It has the functions of air flotation, sterilization, and disinfection;

4. It can be treated as a standalone process or combined with other processes.
