treatment efficiency and appropriate for many kind of wastewater With its advantages than UASB, EGSB techology has been applied very popular in over the world To enhancing the advantage of granular sludge, this experiment used polyvinyl alcohol (PVA) as a biomass carrier to improving organic removal efficiency A lab-scale experiment included two EGSB which 10 liters of each reactor: one with 20% volume PVA carrier while another without PVA Wastewater used in this experiment collecting from a slaughtering and preparing meat company Mixed liquor suspended solid (MLSS), pH and alkalinity (mg CaCO32-) control at 10g/l, 6-8 and 300-800mg/l Organic loading rates (OLRs) varies from 0.5 kg COD/m3.day to 8kg COD/m3.day The result showed that EGSB reactor with PVA use as a biomass carrier has more treatment efficiency and stable than the one without biomass carrier in vary OLRs including at low organic loading stage HVTH Nguy iv M CL C ii iii vii viii 1.1 1.2 1.3 1.4 1.5 2.1 2.1.1 Công ty
