After the thermal hydrolysis of sludge alkali, the solid part is anaerobic fermentation to produce acid

Firstly, the sludge in the secondary sedimentation tank of the sewage treatment plant was subjected to alkaline thermal hydrolysis, and then the obtained sludge hydrolysate was separated from each other by solid-liquid, and the precipitated part was used as a substrate for acid production by anaerobic fermentation

首先，对污水处理厂二次沉淀池中的污泥进行碱性热水解处理；随后将所得污泥水解液进行固液分离，取沉淀组分作为厌氧发酵产酸的基质。
