[0027] Example 1
[0028] By adopting the method of the invention, the medicinal residues of Sophora flavescens are utilized for resource utilization to prepare methane and activated carbon. Specific steps are as follows:
[0029] (1) After air-drying, the Sophora flavescens dregs with a moisture content of 10% (mass ratio w / w) (the main components are: cellulose 38.3%, hemicellulose 23.6%, lignin 14.6%) are pulverized, After passing through a 20-mesh sieve, accurately weigh 33 g of Sophora flavescens dregs under the sieve, add 2.4 g of NaOH to pretreat the Sophora flavescens medicinal dregs, that is, keep 8% (g / g) of the dry weight of the Sophora flavescens medicinal dregs, and add a certain amount of The pure water is mixed evenly, so that the traditional Chinese medicine dregs are completely immersed in the lye, and soaked at room temperature for 24 hours;
[0030] (2) the material after the above-mentioned alkali pretreatment and the domesticated anaerobic sludge are mix...
