| Abstract: | The absorption efficiency of ammonia in the wastewater by diatomite were studied,and the effects of mixing time,settling time,pH,dosage of diatomite and modifier zeolite were investigated.Results indicated that the optimum operation indexes were mixing time of 15.0 min,settling time of 15.0 min,pH of 7.0,diatomite dosage of 0.8 g/L and modifier zeolite dosage of 3.0 g/L.Moreover,the remove rate of ammonia could reached over 85% under diatomite dosage of more than 0.8 g/L. |
