An ammonia -purifying method is provided to be implemented in the series processing, to obtain a high ammonia recovery rate and purity, to replace no an adsorber without an adsorption process and to cause no smell or environmental contamination. Low-boiling point materials including carbon dioxide, methane and nitrogen are removed in the first distillation tower(100). High-boiling point materials including moisture and oil are removed in the second distillation tower(200). The low-boiling point materials including carbon dioxide, methane and nitrogen are ejected in the first distillation tower to a phase of the steam vapor. Ammonia which is product in the second distillation tower is ejected to a phase of liquid.
