1. Electrocatalytic oxidation ammonia nitrogen removal equipment
The ammonia nitrogen wastewater first enters the regulating tank to adjust the water quality, and then enters the electrocatalytic oxidation system for catalytic oxidation. Under the action of the external electric field, the intermediate with high oxidation activity is generated near the plate with catalytic function, which can convert ammonia nitrogen into nitrogen and water, thereby achieving the purpose of removing ammonia nitrogen from the wastewater. The positive and negative electrodes of the electrocatalytic system are arranged at intervals, and the distance between the plates can be flexibly changed to adjust the catalytic reaction area of the system. The system can provide a large current intensity to produce strong oxidizing substances such as OH, H2O2, [O], O3, etc., to oxidize ammonia nitrogen and organic matter; at the same time, it can oxidize chloride ions in the wastewater into hypochlorite and chlorine, and indirectly oxidize pollutants to improve the system's processing capacity.
Electrocatalytic reduction total nitrogen removal process and products
Technical advantages
(1) No chemical agents need to be added, and the electrons generated by the electric field on the cathode surface are directly used as electron donors for NO3 reduction, which will not cause secondary pollution and reprocessing costs.
(2) The electrochemical nitrate reduction process has high treatment efficiency, fast reaction rate, and controllable products. By optimizing electrode materials, reactors, and operating parameters, the generation of N2 can be effectively regulated.
(3) The process is driven by electricity, which can be provided by renewable energy sources such as solar energy and wind energy;
(4) The electrochemical reactor occupies a small area, can be assembled in a modular manner, and is easy to control automatically. It has been widely used in the field of deep wastewater treatment. Therefore, electrochemical reduction to remove NO3- from water is a feasible technology with application prospects.

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.
