The electrolysis method is to remove harmful impurities in wastewater in the form of transformation by generating a series of chemical reactions with the help of external electric current. It purifies pollutants in wastewater through the new ecological oxygen and new ecological hydrogen generated by the two electrodes.
The new ecological oxygen oxidizes organic and inorganic compounds in the water, and the new ecological hydrogen reduces certain pigments in the oxidized state into colorless substances, achieving a good decolorization effect.
Wastewater electrolysis treatment includes processes such as electrode surface electrochemical action, indirect oxidation, indirect reduction, electroflotation and electroflocculation, which remove pollutants in wastewater in different ways.
Biological treatment method
(1) Biosorption method
Biosorption method refers to the biochemical reaction of pollutants adsorbed by biological cells and cell membranes. Its main biosorbents are mainly crops, algae, etc.
The adsorbent of this method can also take some methods to appropriately increase its adsorption capacity like physical adsorption method. Changing the adsorption capacity can be achieved by adjusting the temperature, pH value, etc.
(2) Microbial flocculation method
The microbial flocculation method is mainly based on the flocculation of microorganisms, pollutants and their metabolites (proteins, polysaccharides, etc.), so as to achieve the purpose of removing pollutants.
