近年来,污水处理厂污泥和餐厨垃圾产生量越来越多,且单独处理存在很多问题,两者混合厌氧消化产甲烷发展前景广阔。从国内外近年的研究出发,从原料性质、控制参数、工艺优化三方面进行了总结,认为当前污泥和餐厨垃圾的混合处理还需更多地借鉴两者单独处理时已优化的控制条件,消化液的处理也需得到关注。此外,针对微生物种群演替、抑制因子、环境影响因子(如光照)、复杂有机物的转化、相关处理工艺设备等的研究与应用也需得到更多的开展。
In recent years, sewage sludge and food waste generated more and more, and there are many problems with the separate treatment, the two mixed anaerobic digestion of methane has broad prospects for development. Based on the recent researches both at home and abroad, the paper summarizes the properties of raw materials, control parameters and process optimization. It is concluded that the current mixed treatment of sludge and food waste needs more reference from the optimized control conditions , Digestive juice treatment also needs attention. In addition, the research and application of microorganism population succession, suppression factors, environmental impact factors (such as light), transformation of complex organic compounds, related processing equipment and so on need to be carried out more.
