Method for enhancing efficiency of producing lactic acid from organic wastes, generated during fermentation of sludge, by utilizing positive voltage

The invention discloses a method for enhancing efficiency of producing lactic acid from organic wastes, generated during fermentation of sludge, by utilizing positive voltage. The method comprises the following steps: mixing sludge, fermentation substrate and a starter, then stirring in a fermentation reactor and conducting anaerobic fermentation, providing a positive voltage of a certain value in reaction environment by utilizing an electrode, so as to assist the characteristic of activating sludge. After the fermentation is conducted for certain time, the remarkable increase on the total yield of lactic acid can be seen by determining the fermentation product lactic acid. The lactic acid in the fermented liquor can be extracted by utilizing a common method, thus acquiring extremely high values. The medicament assisted by the method is non-toxic, and the flow and equipment are simple, and the effects are remarkable. 本发明公开了种利用正电压增强污泥发酵有机废物产乳酸效能的方法，包括以下步骤，将污泥、发酵底物以及启动剂混合后放入发酵反应器中搅拌并进行厌氧发酵，利用电极在其反应环境中提供定数值的正电压予
