为了利用淀粉废水生产活性蛋白饲料,采用混凝法从小麦淀粉废水中提取固形物,并在湿态固形物中加入菜籽粕、麸皮、啤酒酵母泥做成培养基,添加适量尿素、光合细菌进行固体发酵生产蛋白饲料.结果表明:在小麦淀粉废水中加入2.5%的石灰乳(质量分数10%)、2%的聚合氯化铝(PAC)溶液(有效铝质量分数5%)、0.8%的聚丙烯酰胺(PAM)溶液(质量分数0.3%)、沉降20min,固形物回收率达82%;用回收固形物:菜籽粕:麸皮:啤酒酵母泥为45:40:10:5(质量比,以干物计),混合均匀做成含水55%～58%的培养基,并添加1.0%的尿素、1.0%～1.5%光合细菌,采用自然光静置培养2.5 d,蛋白质质量分数可达35%.
為瞭利用澱粉廢水生產活性蛋白飼料,採用混凝法從小麥澱粉廢水中提取固形物,併在濕態固形物中加入菜籽粕、麩皮、啤酒酵母泥做成培養基,添加適量尿素、光閤細菌進行固體髮酵生產蛋白飼料.結果錶明:在小麥澱粉廢水中加入2.5%的石灰乳(質量分數10%)、2%的聚閤氯化鋁(PAC)溶液(有效鋁質量分數5%)、0.8%的聚丙烯酰胺(PAM)溶液(質量分數0.3%)、沉降20min,固形物迴收率達82%;用迴收固形物:菜籽粕:麩皮:啤酒酵母泥為45:40:10:5(質量比,以榦物計),混閤均勻做成含水55%～58%的培養基,併添加1.0%的尿素、1.0%～1.5%光閤細菌,採用自然光靜置培養2.5 d,蛋白質質量分數可達35%.

AbstractIn order to get active protein feed from starch wastewater,firstly,solid matter of wheat starch wastewater was extracted by using the coagulating method;Then rapeseed meal,wheat bran and beer yeast slurry were added into the hygrometric state solid matter to make substrate for fermentation;Finally urea and photosynthetic bacteria were put into the substrate and solid fermentation Was carried out.Results:The first step.the recovery of solid matter reaches 82% with adding the following chemicals and precipitating for 20 min:2.5% of Ca(OH),at 10% consistency,2% of PAC solution with 5% effective Al content,and 0.8% of PAM solution at 0.3% consisten-cy.The second step,the established ratio of recovered solid matter,rapeseed meal,wheat bran,and beer veast slur-ry is 45:40:10:5(w/w,dry basis),making a substrate with moisture 55%～58%.Lastly.the conditions of the solid fermentation are urea 1%,photosynthetic bacteria 1.0%～1.5%,and static-culture for 2.5 d under natural daylight.The protein in the substrate reaches 35% after the fermentation.
