Low-temperature anaerobic fermentation method for high-solid-content sludge

The invention discloses a high-solid-content sludge low-temperature anaerobic fermentation method which comprises the following steps: adding 0.5-2g/KG of potassium persulfate into high-solid-content sludge, uniformly mixing, and fermenting for set time; then adding 0.05-3g/g of TSS aged mineralized refuse into the high-solid-content sludge, uniformly mixing, and fermenting at 10-15 DEG C for set time; and after fermentation is completed, carrying out solid-liquid separation on the sludge with high solid content to obtain fermentation liquor rich in VFA, biogas rich in hydrogen and solid mud cakes. 本发明公开了一种高含固污泥低温厌氧发酵方法，包括如下步骤：向高含固污泥中投加0.5-2g/KG的过硫酸钾，混合均匀后，发酵设定时间；然后再向高含固污泥中投加0.05-3g/g TSS老龄矿化垃圾，混合均匀后，在10-15℃发酵设定时间；发酵完成后，将高含固污泥进行固液分离，得到富含VFA的发酵液、富含氢气的生物沼气和固体泥饼。
