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. Al
