| Abstract: | The combined method of ammonia stripping and contact oxidation was yield in treatment of wastewater from fertilizer industry.By experim- ent,the optinum operating parameters were acquired,the best flow chart was selected,and ammonianitrogen was less than 10 mg/1 in outlet wastew- ater.Concerning the temperature of inlet wastewater,the better purificat- ion result was achieved in freeze season by preheating inlet air.with con- troling PH value and selecting plastic filling filler,the lath of CaCo_3 was overcome in pilot plant. |
