Description

technical field [0001] The invention relates to an aeration tank, in particular to a multi-layer aeration device for the aeration tank. Background technique [0002] Alcohol is a very important industrial raw material, which can be used in solvents, reaction reagents, medical materials, food materials and other fields. At present, the annual domestic alcohol production exceeds 9 million tons. The alcohol preparation process consists of five steps: crushing, cooking, saccharification, fermentation, and distillation. The purity of the obtained edible alcohol can reach more than 99.5%. In the fermentation stage, urea, nitrate, etc. must be added as the nutrients of the yeast to ferment the glucose to obtain the product alcohol. Finally, the alcohol wastewater remaining at the bottom of the distillation tower contains high COD and nitrogen: usually, the COD in the alcohol wastewater stock solution is 40,000 -50000 or so, while the total nitrogen content is around 450-600. The...
