Ammonia -nitregon is one of the most important oxide consumal contanints in water, Ammonia in water mainly come from the excrements of people and animals, the wastewater of chemical fertilizer in farm, gas production and coking process, metallurgry industry, and other industry discharged . Ammonia can do harm to the nature and peopole' s health, the high ammonia in water can lead the consumtion of C12 in water plant increasing,So the residual organic cholrine can do harm to the health of people.The treatment of ammonia wastewater is an big problem in our country,The research of ammonia treatment technology is very important.In this thesis, the auther look up a lot of documents, and research for the treatment technology of ammonia in wastewater of wet smelt plant.combine to the high ammonia wastewater, systemal researches have been done,the auther put forward the best treatment flow chart in the end,just like the follows:1, use the technology of lime - stripping-oxidine process treat the high ammonia wastewater, ammonia in the treated wastewarter is less 15mg/L, the faundation process is:use lime to treat the extration raffinate ammonia wastewater first, and control the pH value to 11-12, then striping 2.5 hour in normal states, at the last use the oxidizer like Ca(C10))z 0. 3-0. 5g/L to oxide the ammonia in wastewater for 30 min, treated warter can be reused and discharged.2 , this treatment process have many supiriores, treated wastewater can meet the national discharge standards.
