糖蜜酒精废液农用资源化治理技术

介绍两种农用资源化治理糖蜜酒精废液技术：①配成甘蔗专用肥液：新鲜废液经调整pH值、添加补充必要的营养元素，配成甘蔗可直接施用、养分配比合理的有机-无机液体肥料，在甘蔗播种后把该肥液淋施于植沟内，并采用专用地膜覆盖栽培技术，把废液密封在地膜覆盖形成的小生态环境快速降解、转化为甘蔗可直接吸收利用的养分和水分，施后对甘蔗萌芽、幼苗生长无不良影响，对土壤不产生酸化、板结。②浓缩配制戍颗粒甘蔗专用有机-无机复合肥：新鲜废液送至贮箱，在中和器内用氢氧化钠中和，经多效蒸发器浓缩为总固形物50％～75％的浓缩液，必要时再经熟化反应、喷雾和干燥后制成干粉，再配与氮、磷、钾单体化肥，以及粉炉灰、蔗髓等混合，制成颗粒状商品型有机-无机复混肥。

Technology of treating molasses vinasse as agricultural resource

Two ways of treating molasses vinasse as agricultural resources were introduced： the first was to be used as a liquid fertilizer special for sugarcane： adding some essential elements and regulating the vinasse pH value, irrigating in the planting furrows after sowing, and covering the planting furrow with a plastic film special for sugarcane cultivation, which would increase the soil temperature and humidity in the film and accelerate the vinasse decomposing and turning into nutrients and water, this liquid fertilizer had no negative effect on sugarcane germination, growth, and soil chemical property.The second was to be concentrated and made into organic and inorganic compound fertilizer special for sugarcane：storing the fresh vinasse up, neutralizing it with sodium hydroxide, concentrating into 50% -75 % liquid （or concentrating into powder through spraying and drying, if necessary）, mixing with chemical fertilizers of nitrogen, phosphorus and potassium, stove ashes, and bagasse pith, and finally making into commercial organic and inorganic compound fertilizer.
