Abstract :
A bench-scale experimental study was carried out to investigate the overall performance of a combined anaerobic reactor (CAR)for treating mustard tuber wastewater at organic loading. The experimental results show that Under the conditions that temperature is 30°C and loading is 7.5 kgCOD/(m3 · d), the influent mustard tuber wastewater with salinity of 1.8(C1-) and COD of 4500mg/L is treated to 500mg/L of the effluent COD, with removal rate at 88.64%. The results of electron microscope scanning (SME)show that different dominant microorganisms present in the central area and outer area. The superior microorganisms of central area are Methanosarcina and Methanobrevibacter Ruminatium, while the superior microorganisms of outer ring from the first reaction area to the sixth reaction area are mainly consisted of Methanothrix Soehn genii.
