水解-混凝法处理糖蜜酒精废水试验

Experiment on sugar-syrup alcohol wastewater treatment by dominant-microorganism added hydrolysis-flocculation technique

采用投加优势菌群的水解 -混凝法对糖蜜酒精废水进行试验 ,研究投加优势菌的水解阶段的处理效果 ,同时 ,以 10 %碱式AlCl3为混凝剂 ,对水解段的出水进行混凝处理 ,并对处理条件进行研究。结果表明 ,采用投加优势菌群的水解 -混凝法工艺处理该废水 ,可以取得 5 8%的CODCr去除率 。

In this paper a new treatment process for sugar-syrup alcohol wastewater was investigated. Experiments were done under the dominant microorganisms added hydrolysis process. Also, coagulation was combined with the biological treatment. Using AlCl 3 (10%) as the coagulant, the coagulation conditions were invested. It was showed that 58% of the COD Cr removal rate could be achieved after using the technique of dominant microorganisms added hydrolysis-flocculation and the chroma could be decolored.
