用海藻制备絮凝剂处理蛋白废水的研究

Disposing Protein Wastewater by Using Flocculant Made from Seaweed

拟从海藻中提取天然高分子絮凝剂,采用化学絮凝法处理含蛋白质的废水,从中回收絮凝产物。文章对目前国内外用絮凝剂处理蛋白废水的现状进行分析,指出了用天然高分子材料在该领域的突出特点———无毒无害,絮凝产物富含蛋白质可作为动物饲料添加剂。研究结果表明:单以化学絮凝法处理蛋白废水,出水尚不能达到国家标准要求,可以作为预处理,降低COD负荷。

The flocculant was made from seaweed which can be used to dispose protein wastewater and the flocculent outcome was abtained from the wastewater. This paper discussed the actuality of using flocculant to dispose protein wastewater in domestic and overseas. The outstanding characteristics of using crude macromolecule in this field was stressed —innocuity. The flocculent outcome has plenty protein which can be used as propagation feedstuff. Experimental results showed that the protein wastwater which be disposed only by flocculant can not achieve the national standard. It can pretreatment protein wastewater to reduce COD.
