| Abstract: | Two different biological filter medium were prepared from diatomite and coal fly ash based on attapulgite,and their properties were tested by PSD.SEM before and after the biofilm was studied,with detection of the removal rates of COD and NH3-N as well as DO.Results showed that the two biological filter medium had good performance.The diatomite and attapulgite filter medium of biofilm formation and water treatment performance were superior to that of coal fly ash and attapulgite filter. |
| Keywords: | attapulgite diatomite coal fly ash biological filter medium |
