AI Technical Summary
In existing online BOD measurement methods, the oxygen consumption during the amino nitrogen nitrification process can interfere with the detection results, leading to inaccurate measurements. Furthermore, commonly used nitrification inhibitors are toxic and carcinogenic, and long-term use is detrimental to the environment.
By coupling an environmental microbial membrane reactor and a nitrifying microbial membrane reactor, the oxygen consumption of organic matter and inorganic ammonia is measured separately, and the BOD of the actual water sample is calculated by the difference, eliminating the need for nitrification inhibitors.
It achieves accurate BOD measurement and online analysis, avoids the use of carcinogenic nitrification inhibitors, and meets the requirements of green development.
