Abstract

The invention discloses a method for high-value recovery and utilization of molasses alcohol waste liquid. The invention has the beneficial effects of reducing waste water discharge, reducing energy consumption, and no secondary pollution, and using waste water to produce feed, using microbial agents, waste rapeseed from beet sugar factories and treated molasses fermentation waste liquid to prepare feed, Strengthen the beneficial bacteria in the digestive system of animals, improve digestibility, maintain normal metabolism, and enhance disease resistance. The prepared feed is easy to store and put in, greatly improving its utilization rate.

Description

technical field [0001] The invention relates to the field of recycling and utilization of molasses alcohol waste liquid, in particular to a method for high-value recycling of molasses alcohol waste liquid. Background technique [0002] Beet molasses alcohol waste liquid is the waste liquid discharged from the bottom of the distillation tower after the beet sugar factory uses molasses as raw material to ferment the alcohol. It is very polluting to the environment. Seriously, it contains a very large amount of suspended matter and organic matter, its pH value is 4.2-4.6, BOD is 5.7-6.7×104mg / L, COD is 10-13×104mg / L, and suspended matter (SS) is 2.5-5 ×103mg / L, the color value is as high as 120,000-140,000 IU, containing 10-20% of solid solution (including 15-20% of crude protein; 25-30% of minerals; nitrogen-free leaching of residual sugar, colloid, vitamins, amino acids, etc. material 45~52%). Molasses fermentation waste liquid (alcoholic fermentation waste water and molass...
