The invention relates to a method for resourceful treatment of
ammonia chloride wastewaters. The method comprises the following steps: (1) respectively carrying out pretreatment on
ammonia chloride wastewater with different concentrations for removing impurities; (2) carrying out
reverse osmosis treatment on a clear liquor of the
ammonia chloride wastewater, which is obtained in the step (1), with the concentration being lower than 0.5%; (3) mixing obtained
reverse osmosis concentrated water with a
clear liquid of the ammonia chloride
wastewater, which is obtained in the step (2), with the concentration being higher than 0.5% so as to obtain ammonia chloride mixed wastewater; (4) carrying out conventional
electrodialysis treatment on the obtained ammonia chloride mixed wastewater so as to obtain
electrodialysis fresh water; (5) returning the obtained
electrodialysis fresh water, carrying out
reverse osmosis treatment the obtained electrodialysis
fresh water to obtain electrodialysis concentrated water, and carrying out acid-alkali regeneration on the electrodialysis concentrated water by adopting bipolar membrane electrodialysis; and (6) converting ammonia chloride in the wastewater into
hydrochloric acid and
ammonium hydroxide by adopting the bipolar membrane electrodialysis to obtain low-concentration ammonia chloride wastewater, simultaneously returning the obtained low-concentration ammonia chloride wastewater and carrying out the conventional electrodialysis treatment on the obtained low-concentration ammonia chloride wastewater. According to the method, the resourceful treatment and the
zero emission of the ammonia chloride wastewater can be really achieved.
