一种难降解氨氮废水的处理系统、及处理方法
摘要：
本发明涉及一种难降解氨氮废水的处理系统，所述系统包括依次连接的生物好氧脱碳单元、厌氧氨氧化单元和硝化-反硝化单元。本发明提供的难降解氨氮废水的处理方法适用于焦化废水、煤气化废水、制药废水、发酵废水、食品企业废水等难降解含较高浓度氨氮废水，还可以用于市政废水、生活污水的处理；且能够将难降解氨氮废水的总氮可以控制在15mg/L以下，达到国家一级排放标准。
摘要（英）：

The invention relates to a degradation-resistant ammonia-nitrogen wastewater treatment system. The system comprises a biological aerobic decarburization unit, an anaerobic ammonium oxidation unit and a nitrification-denitrification unit and the above units are orderly connected. The method is suitable for treatment on degradation-resistant high-concentration ammonia-nitrogen wastewater such as coking wastewater, coal gasification wastewater, pharmaceutical wastewater, fermentation wastewater and food enterprise wastewater and can also be used for municipal wastewater and domestic sewage treatment. Through the system, the total nitrogen content of the treated degradation-resistant ammonia-nitrogen wastewater is controlled to 15 mg/L or less so that the national first-level emission standard is satisfied.
