摘要: This study was aimed to behaviour of organics and nitrogen on the upflow anaerobic reactor when a acid fermenter is added. Up flow (UAR) reaction will result which operates, COD removal efficiencies with nitrate loading rate 0.11, 0.66g/L/d were over 77%, but one 1.0g/L/d 73.5%. Especially, NLR 0.11g/L/d, 77% efficiency 93% simultaneously. The other side (UAR+AF) witch 85%, 80%. 85% 98% Also, without in condition increase influent concentration resulted linear decrease at nitrate-nitrogen 800mg/L 50%. Alkalinity increased theoretically by denitrification low nitrate-N concentration, however, it not high nitrate-No 40% UAR denitrified until 70% height 90% UAR+AF 30% Upflow occur accumulate acid, TVA/Alkalinity 0.30.47. Increase effluent alkalinity TVA production
