THE PRESENT AND FUTURE OF HYDROGEN PRODUCTION FROM WASTEWATER
Hydrogen energy is an important part of the future national energy system and a key development direction for strategic emerging industries,and developing green and environmentally friendly hydrogen production technology is an important support for building China's future hydrogen energy system and realizing the Dual-Carbon Goal.However,the current mainstream renewable energy technology of hydrogen production from electrolyzed water has very high requirements on water quality,consumes a large amount of clean water,and causes an imbalance in resources and energy.The preparation of green hydrogen from wastewater can simultaneously solve the two major problems of wastewater treatment and freshwater consumption for hydrogen production,which is an ideal strategy to achieve carbon neutrality in wastewater treatment.In this paper,the current status and challenges of wastewater hydrogen production technology are systematically reviewed from the perspectives of principle,equipment,and process,and the current engineering application of combined pretreatment and electrolysis through biochemical and membrane filtration in wastewater hydrogen production is analyzed.At the same time,this paper summarized the innovative integration path of cyclone technology and wastewater electrolysis for hydrogen production.Through the engaging of cyclone technology and the enhancement of mass transfer and flow field control,high efficiency and low energy consumption of hydrogen output in the process of sewage electrolysis can be realized,which will create a win-win situation for resource utilization of sewage and production of clean energy.
