Study on the Treatment of wastewater from the Production Process of Vitamin C by Using a Complex Reactor of Upflow Anaerobic Sludge Blanket-Filter
UASB+AF处理维生素C废水的研究

A complex reactor of upflow anaerobic sludge blanket-filter (UASB+AF) with an available volume of 6m3 was used to treat a highly concentrated organic wastewater from the production process of Vitamin C. During the Period of its stable operation,it had a volumetric COD loading of up to 10-12kg COD/ (m3.d ), a COD removal of over 80%, and a volumetric biogas yield of over 3.0 Nm3/(m3.d),as well as a high start-up speed and a stronger resistance to shock loading.
