从淀粉废水中提取蛋白饲料

Protein Feedstuff Extracting from Starch Wastewater

淀粉废水中主要含有蛋白质、脂肪、纤维素等,采用气浮分离技术能够从1t淀粉废水中提取5kg蛋白饲料,同时废水中的SS和CODCr去除率分别达80%和30%以上,减轻了后续生物处理的有机负荷。

A starch wastewater mainly contains proteins, fats and celluloses. From one ton of the wastewater 5 kg protein feedstuff could be extracted. Meanwhile removal rates of the SS and CODCr of the water reached more than 80%and 30%respectively. Thus the organic load for further treatment was lowered.
