China Environmental Science. 2002,22(4) 370~374 Abstract The simulated organic wastewater containing sucrose and starch was treated with natural anaerobic microor- ganism bacterium from cow dung compost. The biohydrogen was produced through anaerobic hydrogen fermentation with synchronous purification of the wastewater. Under the experimental conditions, the hydrogen concentration in the biogas reached 61% without methanogenesis in the gaseous product. The maximum hydrogen productivity was 146mL/g and 166mL/g under the conditions of initial pH value of 6.0 and 7.5 and substrate of sucrose and starch respectively. The optimal concentrations of these two substrates were 5g/L. The COD removal efficiency could reach 40%~60% in the simulated wastewater.
