摘　　要：对于合成氨工业生产废水水量大,水温高、高氨氮、碳氮比低、可生化性差的特点,采用收集池+汽浮+均化调节池+两级A/O(SND)+二沉池+混沉池的组合工艺进行处理,运行结果表明COD,NH_(3)-N,TN、SS去除率可分别达到90%,98%,93%,98%,出水达到《合成氨工业水污染物排放标准》(CB 13458-2013)表2直接排放标准。For the characteristics of synthetic ammonia industry waste water,high temperature,high ammonia nitrogen,Lowcarbon and nitrogen ratio and poor biochemical characteristics,the combination of collection pool+air floating+regulation poo+two-stage(SND)of A/O +secondary sedimentation tank+Coagulation sedimentation tank was used for treatment,the resultsshow that removal rate of COD,NH_(3)-N,TN,SScan can reach 90%,98%,93%and 98%respectively,achieve "ammonia water industrial water pollutant discharge standard"(GB 13458-2013)direct emissions standards in table 2.
