Treatment of Monosodium Glutamate Production Wastewater by Aerobic Granular Sludge Process
摘要
Abstract
Monosodium glutamate production wastewater was treated by aerobic granular sludge process. The experimental results show that: The effect of the pre-setting anoxic section on denitrification is little, and the denitrification process is mainly realized in the aerobic section; The optimum operation conditions in aerobic section are aeration rate 0.38 m3/h and aeration time 5.5 h; When COD, p(NH3-N) and TN of the influent are 1 000.00-1 300.00, 70.00-130.00, 100.00-200.00 mg/L, the removal rates of COD, p(NH3-N) and TN can reach more than 90%, 99% and 85% respectively; The organic compounds are mainly removed during the first 1.5 h of aeration, and they are stored in microorganism cells in the form of poly-β-hydroxybutyrate, which is the carbon source for denitrification. Comparing with the conventional SBR, the aerobic granular sludge process has a higher effect on the treatment of monosodium glutamate production wastewater.关键词
