Method for deaminating cobalt carbonate production wastewater

The invention relates to a method for deaminating cobalt carbonate production wastewater, and belongs to the technical field of wastewater treatment. The cobalt carbonate production wastewater is treated by combining an extraction method, a resin adsorption method and a direct evaporation method, oil and metal ions in the wastewater are effectively removed, a large amount of ammonia nitrogen is changed into a first-grade high-quality ammonium sulfate byproduct through evaporative crystallization, and then trace ammonia nitrogen in evaporated water is efficiently and thoroughly treated through modified ammonium removal resin. The method not only can realize cyclic utilization of various substances, but also can efficiently and thoroughly treat ammonia nitrogen in the cobalt carbonate production wastewater, and solves the difficult problem of the previous old process by using resin adsorption, biochemical treatment of COD and resin adsorption to remove metal ions, so that the cobalt carbonate production wastewa
