摘要

In the increasingly demand of renewable energy, disposed sludge from the bottom of a river was used to ferment artificial organic water for hydrogen. In this way, biological hydrogen production and waste remediation have been studied. The results showed that the total hydrogen production from three types of artificial organic water respectively contained glucose, sucrose and starch were 309.36mL , 318.18mL , 8.20mL , at the same conditions that the concentrations of sugar substratum were 1.67g·L~(-1) ,V (volume of organic water) =300 mL, pH=5.5. T=40°C. The total hydrogen production of artificial water contained sucrose was the highest. The removal rates of the COD from artificial water containing sucrose, glucose and starch were respectively 78.00%, 76.92% and 55.00%, and the nitrogen removal were respectively 17.84%, 22.42%, 15.73%. Moreover, it was found out that the status of gas production was related to the growth curve of four bacteria colonies screened from the sludge. The process of anaerobic fermentation for hydrogen was complicated. It was affected by various factors such as the type and concentration of substrate, pH as well as temperature etc. By adopting disposed sludge to ferment organic water contained high concentration of sugar, not only did it product a large proportion of biological hydrogen energy, but also remediate waste to some extent.
