ammonia nitrogen treatment

The results show that in-depth treatment process have good removal effect for the COD, BOD, total phosphorus, ammonia nitrogen, suspended particulate, turbidity, OIL and total iron of waste water.

结果表明：深度处理工艺对源污水中COD、BOD、总磷、氨氮、悬浮物、浊度、OIL、总铁等均有很好的去除效果。

The operation results show that the basic oxidation is effect to decrease the contents of ammonia nitrogen, phosphide and salt. This is very favorable to the following biological treatment.

实践证明利用碱解氧化可降低浓废水中的氨氮、 磷化物及盐浓度，对保证后续生物处理系统正常运行有重要作用。

Due to higher content of protein in chondroitin sulfate wastewater and low measured value of ammonia nitrogen, organic nitrogen was neglected in designing wastewater treatment process.

硫酸软骨素废水中蛋白质含量虽然较高，但氨氮测定值较低，导致有机氮问题在设计时容易被忽视。
