Problems solved by technology

[0002] At present, wastewater containing high concentrations of organic matter and ammonia nitrogen is a type of organic wastewater that is difficult to treat
At home and abroad, anaerobic-aerobic technology is mainly used for treatment. Although anaerobic treatment can degrade organic pollutants in wastewater to a large extent, the concentration of anaerobic effluent pollutants is still high, especially ammonia nitrogen is basically not removed.
For the treatment of pig farm wastewater anaerobic digestion liquid, biological nitrification and denitrification are the most widely used. Although nitrifying bacteria and denitrifying bacteria can be used to convert nitrogen-containing organic matter and ammonia in wastewater into nitrogen and remove them, high concentrations of organic matter and ammonia nitrogen It usually increases the treatment load and impact load of microorganisms, resulting in poor wastewater treatment effect
In actual engineering, in order to improve the removal effect of ammonia nitrogen, alkalinity or carbon source is usually supplemented in the process of denitrification and denitrification, which increases the treatment cost and operating cost
