Advantages and Technical Features of Micro-Electrolysis ...

(2) It has a wide range of organic pollutants, such as difficult-to-degrade organic substances containing fluorine, carbon double bonds, nitro, and halogenated structures, and boasts an excellent degradation effect.

(3) The process is simple and user-friendly. The service life is long, the investment cost is low, and operation and maintenance are convenient. The operating cost is minimal, and the treatment effect remains stable. During the treatment process, only a small amount of micro-electrolysis reagent is consumed. The micro-electrolyzer only requires regular additions without the need for replacement, and it can be directly added without prior activation.

(4) Following micro-electrolysis treatment, ferrous or ferric ions are formed in the water, providing a coagulation effect superior to ordinary coagulants. There is no need to introduce coagulants, such as iron salts. The COD removal rate is high, preventing secondary pollution in the water.

(5) This method yields a good coagulation effect, achieving high chroma and COD removal rates, significantly enhancing the biodegradability of the wastewater.

(6) The technique facilitates chemical precipitation and phosphorus removal, in addition to heavy metal reduction.

(7) For high-concentration organic wastewater treatment projects that are already constructed but do not meet standards, this technology can serve as a pretreatment to ensure stable discharge post-treatment. It is also feasible to isolate high-concentration wastewater from production wastewater for micro-electrolysis treatment.

(8) Each unit employing this technology can function as a standalone treatment method and can serve as a pretreatment step for biological treatment, which supports sludge sedimentation and biofilm formation.
