Description

technical field [0001] The invention relates to a method for treating waste water with high ammonia nitrogen combined with electric field strengthening and anaerobic ammonium oxidation membrane bioreactor, which belongs to the technical field of environmental protection. Background technique [0002] Anaerobic ammonia oxidation (Anammox), its basic principle is that ammonia nitrogen oxidizing bacteria oxidize and decompose nitrogen-containing organic matter, convert it into ammonia nitrogen, and then convert it into nitrate radicals by nitrifying bacteria, and denitrifying bacteria convert nitrate radicals into nitrogen gas. In order to achieve the purpose of denitrification. Compared with the traditional biological denitrification process, the anammox process can save about 60% of the oxygen consumption and 100% of the organic carbon source, but due to the slow proliferation of anammox bacteria, the sludge loss of the traditional biochemical reactor Seriously, resulting in...
