Device and method for treating high-salt ammonia-nitrogen-containing wastewater by coupling microelectrolysis with nitrifying bacteria

The invention relates to a device and method for treating high-salt ammonia-nitrogen-containing wastewater through micro-electrolysis coupled nitrifying bacteria, the device comprises an aeration tank reactor, the aeration tank reactor comprises an aeration structure, a filter plate structure and a filler layer which are sequentially arranged from bottom to top, the filler layer consists of a plurality of layers of fillers which are alternately paved according to the sequence of iron-carbon fillers and ceramsite fillers from bottom to top. Under the action of a micro electric field formed by the iron-carbon filler, the permeability of cell membranes of the nitrifying bacteria is changed, the activity of the nitrifying bacteria is enhanced, the salt tolerance of the nitrifying bacteria is improved, the domestication time of the nitrifying bacteria in the high-salt wastewater containing ammonia nitrogen is shortened, and the ammonia nitrogen treatment capacity of the nitrifying bacteria in the high-salt wastewa
