Popis:	We realize the goal of removing ammonia nitrogen in ammonium paratungstate crystal parent by using strong sodium tungstate liquid to transform-magnesium salt to take off ammonium thoroughly. The results show that removal rate of ammonia can up to 98.88%, ammonia nitrogen contented in the liquid can down to 0.042g/l. Diluting sodium tungstate solution which has been disposed through the above way can be used to confect liquid before the ion exchange,the liquid with the ion exchange can reach the national effluent standard..
