Ammonia nitrogen wastewater mainly comes from fertilizers, coking, petrochemicals, pharmaceuticals, food, landfills, etc. A large amount of ammonia nitrogen wastewater discharged into the water body will not only cause eutrophication of the water body, cause black odor, but also increase the difficulty and cost of water treatment. People and organisms produce toxic effects. The treatment processes for ammonia nitrogen wastewater include various treatment processes such as biological methods and physical and chemical methods.
At present, with the rapid development and growth of fertilizers, petrochemicals and other industries, the high ammonia nitrogen wastewater generated therefrom has also become one of the limiting factors for the development of the industry; it is reported that red tides have occurred in China’s seas many times, and ammonia nitrogen is one of the important reasons for pollution. Especially the pollution caused by high concentration ammonia nitrogen wastewater. Therefore, the cost-effective control of high-concentration pollution has also become an important subject of environmental protection workers’ research, which has received great attention from the industry. The general formation of ammonia nitrogen wastewater is caused by the coexistence of ammonia water and inorganic ammonia. Generally, the main source of ammonia nitrogen in wastewater with a pH above neutral is the combined action of inorganic ammonia and ammonia water. Mainly due to inorganic ammonia. There are two main types of ammonia nitrogen in wastewater, one is ammonia nitrogen formed by ammonia water, and the other is ammonia nitrogen formed by inorganic ammonia.
At present, domestic and foreign high-concentration ammonia nitrogen wastewater treatment methods mainly include the stripping method, the turning point chlorine method, the biological denitrification method, etc., but these methods have different degrees of limitation in terms of treatment effect, economy and field application. Ammonia nitrogen wastewater treatment is an ammonia nitrogen treatment method that can take into account simple processes, small investment, mature technology, convenient control, and no secondary pollution. The electrolytic method has attracted more and more attention. Its advantages include no secondary pollutants, easy operation, remote control, and wide adaptability.
Electrolytic ammonia nitrogen wastewater treatment can effectively remove ammonia nitrogen and other pollutants in wastewater. Has been used by researchers at home and abroad for the treatment of complex high-concentration ammonia nitrogen wastewater.
The main components of electrolytic ammonia nitrogen wastewater treatment include:
Power supply: DC power supply with constant voltage and current;
Electrolysis cell: Ammonia nitrogen wastewater treatment titanium anode plate and cathode plate.
The titanium anode plate material for ammonia nitrogen wastewater treatment produced by our company is selected according to the characteristics of high ammonia nitrogen wastewater. The insoluble anode coated with precious metal oxide on the titanium substrate provides new ideas for the electrolytic treatment technology of ammonia nitrogen wastewater. In addition to having excellent electrocatalytic activity, the electrode can also maintain high stability in the electrolytic system, and the electrode itself will not cause secondary pollution.
