Method for preparing fertilizer effect type molasses alcohol waste mash bacterial liquid through triple fermentation

The invention discloses a method for preparing a fertilizer effect type molasses alcohol waste mash bacterial liquid through triple fermentation. The method comprises steps of: inoculating high-temperature bacillus thermocoagulans Sp.nov. into a high-tempreature (90 DEG C) molasses alcohol waste mash which is just discharged to be fermented preferentially so as to prevent the waste mash from getting smelly in a cooling process due to putrefying bacteria contamination; cooling the waste mash to be below 45 DEG C, and then inoculating strains of Alicaligenes ACCC 02841 and strains of Alicaligenes faecalis ACCC 01720 for secondary fermentation so as to improve the pH of the waste mash; and finally, adding Bacillus macilaginosus, BacillusmegateriumGMCC 1.270 and Rhizobiumradiobacter for the third fermentation, thus preparing the organic waste mash bacterial liquid which is safe and odor-free and has a lasting fertilizer effect. The waste mash bacterial liquid after triple fermentation can be fully used as an agri
