Problems solved by technology

[0003] Due to biodegradation, organic wastewater will make the receiving water anoxic or even anaerobic, and most aquatic organisms will die, resulting in stench, deteriorating water quality and environment
The second is sensory pollution: organic wastewater not only makes the water lose its use value, but also seriously affects the normal life of people near the water
The third is toxicity hazards: ultra-organic wastewater contains a large amount of toxic organic substances, which will accumulate and store in natural environments such as water bodies and soils, and finally enter the human body, endangering human health

Description

technical field [0001] The invention relates to a process for improving the biodegradability of sewage and performing advanced treatment on it, and more specifically relates to a device for purifying refractory organic waste water by nano-aeration iron-carbon micro-electrolysis. [0002] The invention also relates to a method for treating refractory organic wastewater by using the above-mentioned device. Background technique [0003] Due to biodegradation, organic wastewater will make the receiving water anoxic or even anaerobic, and most aquatic organisms will die, resulting in stench, deteriorating water quality and environment. The second is sensory pollution: organic wastewater not only makes the water lose its use value, but also seriously affects the normal life of people near the water. The third is toxicity hazards: ultra-organic wastewater contains a large amount of toxic organic substances, which will continue to accumulate and store in natural environments such a...
