查询词典 basic carbonate

Adjusting pH to 12, air-liquid ratio to the range of 3 000～4 000 and temperature to the range of 35～45℃, after the washing wastewater from deposited ammonium carbonate that the initial concentration of ammonia nitrogen was 1 570 mg/L was treated by ammonia stripping, the residual concentration of ammonia nitrogen was controlled to below 100 mg/L and removal efficiency reached to over 94%.
