利用无患子皂苷生产下脚料促进剩余污泥发酵产酸的方法
摘要：
本发明公开了一种利用无患子皂苷生产下脚料促进剩余污泥发酵产酸的方法，包括：（1）将无患子皂苷生产下脚料干燥：（2）将无患子皂苷生产下脚料投加到浓缩的剩余污泥中；（3）对剩余污泥进行厌氧发酵；（4）对发酵液进行固液分离，得到含有挥发性脂肪酸的清液。本发明通过添加无患子生产下脚料，提高剩余污泥水解发酵产酸量，同时实现无患子下脚料资源化利用和剩余污泥减量。
摘要（英）：

The invention discloses a method for promoting ferment acid production of excess sludge through soapnut saponin production leftovers. The method includes the steps of firstly, drying the soapnut saponin production leftovers; secondly, putting the soapnut saponin production leftovers into concentrated excess sludge; thirdly, conducting anaerobic fermentation on the excess sludge; fourthly, conducting solid-liquid separation on ferment liquid to obtain clear liquid containing volatile fatty acid. By adding the soapnut saponin production leftovers, the hydrolysis fermentation acid yield of the excess sludge is increased, and meanwhile the resource utilization of the soapnut saponin production leftovers and the consumption decrease of the excess sludge are achieved.
