The invention discloses a manganese slag field in-situ treating agent and a using method thereof. The manganese slag field in-situ treating agent is formed by mixing the following raw materials in parts by mass: 15-30 parts of nano-scale calcium carbonate, 5-15 parts of sodium carbonate, 5-10 parts of ammonium bicarbonate and 55-65 parts of wormcast. The manganese slag field in-situ treating agent has the key point that manganese ions in a slag field and a percolate solution are mineralized by selecting excellent and efficient instant ion-type and nano-scale slow-release type manganese mineralizing agents and adopting a scientific proportion so as to generate insoluble minerals, and therefore, the ion activity is reduced, the ions are enabled not to migrate and transform under the nature condition so that the purpose of treating the pollution of the manganese slag field is achieved. According to the using method, by using a solubility product principle, carbanions are introduced in manganese slag to ensure that the free-state manganese ions are combined with the carbanions to form insoluble manganese carbonate, and the free-state manganese ions in the manganese slag are transformed into mineral-state manganese ions, and thus the manganese ions are fixed.
