“利用玉米酒精废液制取沼气集中供气”试点是农牧渔业部一九八四年下达的项目,于一九八八年八月十一日通过部级鉴定。白城市酿酒总厂四分厂,是一个年产6000吨酒精厂,日排放糟液300吨。高浓度废水直接排掉,是个极大的浪费,并给环境带来影响和危害。针对上述存在的问题,以解决能源为扭带,以全面治理为目的,安装了上流式AE+UASB相结合的发酵装置,进行综合利用,效益显著。一是余热回收,节约能源。酒精蒸馏出口温度105℃,降至70℃每天可节煤4.4吨,
The pilot project of “using corn alcohol waste liquor to produce biogas for centralized gas supply” was a project issued by the Ministry of Agriculture, Animal Husbandry and Fishery in 1984 and passed ministerial level appraisal on August 11, Baicheng Brewery Plant four plants, is an annual output of 6000 tons of alcohol plant, 300 tons of decadent emissions. Direct discharge of high-concentration wastewater is a great waste and has an impact on the environment. In view of the above problems, in order to solve the energy twisting band, for the purpose of comprehensive governance, the installation of a combination of high-grade fermentation device AE + UASB, comprehensive utilization, significant benefits. First, waste heat recovery, energy conservation. Alcohol distillation outlet temperature 105 ℃, down to 70 ℃ per day 4.4 tons of coal,
