餐厨废弃物产气性能研究

Research on Gas Production Performance of Kitchen Waste

考察了餐厨垃圾在不同底物质量浓度、pH值、原料配比以及光照时间下的产气性能.结果表明:底物质量浓度为10%,适当控制pH值,原料最佳配比方案为米饭∶猪肉∶生菜=38∶32∶30;每日光照时间12 h的条件下厌氧发酵产气性能最佳.本研究为厌氧发酵技术应用奠定理论基础.

In this paper,gas production performance of kitchen waste under different substrate concentrations,pH values,raw material ratios and light time are investigated.The results showed that:under the condition of the substrate concentration of 10%,appropriate control of pH value,the optimal raw material ratio of rice∶pork∶lettuce=38∶32∶30,and the daily light time of 12h,the gas production by anaerobic fermentation demonstrated its best performance.This paper lays a theoretical foundation for the application of anaerobic fermentation technology.
