Abstract

The invention discloses a biomembrane electrode coupled artificial wetland reactor and a sewage treatment method thereof. The biomembrane electrode coupled artificial wetland reactor adopts the upper layer of the artificial wetland with graphite as the anode, and the lower anaerobic environment with steel mesh and activated carbon as the composite cathode. For sewage treatment, the denitrification and microcystin removal efficiency of the reactor can be enhanced by introducing a certain microcurrent. The invention has the advantages of simple device, convenient operation and management, good treatment effect and small occupied area, and can remarkably improve the treatment effect of sewage containing nitrogen and microcystin.

Description

technical field

[0001] The invention relates to the technical field of water treatment, in particular to a biological membrane electrode coupled artificial wetland reactor and a sewage treatment method thereof. Background technique

[0002] In recent years, with the widespread use of various chemical substances such as fertilizers, detergents, and pesticides, and the discharge of a large amount of domestic sewage, some unreduced nitrogen enters the water environment in the form of nitrate, and the concentration of nitrate in groundwater has gradually increased. In some areas, it has reached 40mg / L. However, the limit value of nitrate in my country's "Drinking Water Quality Standard" is less than 20mg / L. From this point of view, the traditional biological treatment process can no longer satisfy the removal of nitrogen. At the same time, in recent years, as a tertiary treatment project for advanced wastewater treatment, constructed wetlands can further reduce the discharge o...
