| Abstract: | This paper presents a new technology,which includes pretreatment,two-stage distillation,and air stripping of ammonia,to treat wastewater with a flowrate of 50m 3/h and very high concentrations of ammonia(12000mg/L) and CO 2- _3(10000mg/L).The process can bring ammonia concentration in effluent down to below 50mg/L and achieve considerable economic benefit from recovery. |

| Keywords: | wastewater from unit-made sodium carbonate manufacture two-stage distillation air stripping resource recovery |
