Abstract: | Brewery wastewater was treated in the lab-UASB reactor which has a reaction volume of 255 L.By adding bentonite and polyacrylamide into the anaerobic seed sludge,stable granular sludge bed was obtained within 4 weeks with intermittent feed at room temperature (16~31℃).The COD loading rate was 6 kg/m3·d. The COD removal rate was 90%.The cooperation of bentonite and polyacrylamide was discussed in the paper. And the granulation process was studied by optical microscope and scanning electron micrographs. |
