Abstract Summary
The treatment of high-concentration organic wastewater is currently a world problem, such as landfill leachate and digested sludge liquor, in which the concentration of organic matter and ammonia and nitrogen is dozens or even hundreds of times that of municipal wastewater. At present, the dual-membrane process is used to remove organic matter and add a large number of chemicals such as methanol as denitrification carbon source denitrification, which greatly increases the cost of treatment. Anaerobic ammonia oxidation (anammox) greatly saves aeration and carbon source and reduces the treatment cost compared with the traditional nitrogen removal process. Aiming at the bottlenecks of high concentration organic wastewater, such as the high cost of “dual-membrane process” and the production of “thick water” and the need to add a large amount of carbon source for biological nitrogen removal, we take the actual high concentration organic wastewater such as landfill leachate and digested sludge liquor as the research object. Using various types of anaerobic ammonia oxidation coupled with electro-oxidation and other technologies to achieve its depth of decarbonization and denitrogenation, improve the treatment efficiency, reduce the cost of treatment of tonnes of water by more than 95% and there is no secondary pollution, to achieve the dual objectives of environmental protection and economic benefits.
