摘　　要：采用氧化絮凝法进行氨氮降解研究。以皂河水为处理对象,探究了次氯酸钠加量、pH、反应时间等对氨氮去除效果的影响。结果表明:当加药顺序为次氯酸钠处理4h、絮凝剂、主要成分为架状结构的高分子无机化合物的除氨氮药剂、pH为6、除氨氮药剂加量为50mg/L时,水中氨氮含量由处理前的13.5mg/L降低到1.210mg/L,低浓度氨氮含量污水的去除效果最好,去除效果达到91.04%。此研究为氧化絮凝法处理城市生活污水、去除水体氨氮提供理论依据。试验探究可知,次氯酸钠对除氨氮药剂去除氨氮影响较大。The ammonia flotation degradation was studied by oxidation flocculation method. The effect of sodium hypochlorite addition, pH and reaction time on ammonia nitrogen removal was investigated. The results showed that when the dosing sequence was sodium hypochlorite treatment for 4 h, the flocculant, the main component of the polymer-based inorganic compound with a frame structure, the pH of 6. The ammonia nitrogen content in the water was 50 mg/L. The removal of 13.5mg/L before treatment to 1.210mg/L low concentration ammonia nitrogen content was the best, and the removal effect reached 91.04%. For the treatment of urban domestic sewage by oxidative flocculation, the reference data can be provided in addition to ammonia nitrogen. According to the experimental investigation, sodium hypochlorite has a great influence on the removal of ammonia nitrogen by ammonia nitrogen removal agent.
