Photovoltaic wastewater and high-efficiency low-consumption treatment process thereof

The invention relates to a high-efficiency low-consumption treatment process for photovoltaic wastewater with high NH4 < + >-N, high NO3 -N and high F . Wastewater after preliminary fluorine removal enters a synergistic short-cut denitrification tank, and a NO3 -N denitrification reaction is controlled in a NO2 -N step through the synergistic effect of heterotrophic short-cut denitrification-sulfur autotrophic short-cut denitrification in the tank, so that whole-process denitrification is avoided, and the denitrification efficiency is improved. According to the method, short-cut denitrification effluent and high NH4 < + >-N silane wastewater are blended in a middle water tank, high-efficiency denitrification is realized through an anaerobic ammonia oxidation reaction tower in the middle, the effluent of the reaction tower enters an MABR pool, and a special layered structure of an MABR biological membrane ensures that nitrification/short-cut nitrification, anaerobic ammonia oxidation and denitrific
