New process for micro electric field reinforced low-carbon nitrogen removal

The invention provides a new process for micro electric field reinforced low-carbon nitrogen removal, which is particularly suitable for treating waste water with high ammonia nitrogen content and high organic substance content. The process comprises anaerobic fermentation reaction and autotrophic synchronous nitrification-denitrification reaction, wherein after the waste water to be treated enters an anaerobic fermentation reactor and is subjected to anaerobic fermentation reaction treatment, most of organic substances are converted into methane through anaerobic fermentation to perform energy recycle and avoid directly converting the organic substances into CO2 to be discharged. The waste water after the anaerobic treatment has few organic substances and then enters a complex three-dimensional electrode-biological membrane reactor. The process realizes autotrophic synchronous nitrification-denitrification by domesticating carbon autotrophic nitrifying bacteria and hydrogen autotrophic denitrifying bacteria attached to particle electrodes in the complex three-dimensional electrode-biological membrane reactor, finally fulfills the nitrogen removal purpose of directly converting the ammonia nitrogen into the nitrogen, does not need to add the organic substances, basically has no CO2 emission, and is a controllable, efficient, low-consumption, 'low-carbon emission' and environment-friendly new process.
