【摘要】 研究了采用投菌水解 (酸化 )—生物接触氧化—混凝法处理酵母生产废水。试验结果表明 ,进水浓度控制在 CODCr值 50 0 0 mg/L左右 ,生化系统可取得较高的处理效率 ;生化处理出水再以碱式氯化铝为混凝剂 ,聚丙烯酰胺为助凝剂进行混凝处理 ,其出水 CODCr值可控制在 2 0 0 mg/L以下 ,并且可部分回流使用。更多还原

【Abstract】 The study is focus on treatment of yeast wastewater by hydrolytic acidification-billogical contact oxidation-coagulatilon.the experiment result shows that the biological treatment system is efficient as influent COD\-\{cr\} is about 5000mg/L.The final effluent COD\-\{cr\} can be controlled under 200mg/L after treated with coagulatin by adding PAC and polyacrylamide to the effluent of bilolgical system.Part of the final effluent water can be used circularly.更多还原
