查询词典 ammoniacal nitrogen

At present, traditional means namely neutralization is usually used to treat these acids in order to meet production requirements, which means great waste of acid and alkali, As to high concentration of ammoniacal nitrogen, since there is no economic and feasible means yet, it is usually discharged directly without any treatment, which has great effects on the surrounding environment.
