摘要
含高浓度氨氮的煤气废水，因碳源不足影响脱氮效果。为此，研究亚硝化型硝化的可能性和可行性。结果表明，影响硝化类型的主要制约因素是游离氨，通过ｐＨ调节来控制游离氨可获得稳定的亚硝化型硝化。
Containing high-strength ammonium nitrogen, Coal gasification wastewater is affected by the deficiency of carbon souroe during the processes of nitrogen removal. Therefore, the possibility and feasibility of nitrosification has been studied here in the paper. It has been shown from the experimental results that free ammonium is the primary restrictive factor of nitrification, that stable nitrosification can be attained by pH adjustment for the control of free ammonia.
