摘要
根据炼油废水成分分析的结果筛选降解烷烃、苯系物、苯酚等难降解化合物的高效降解菌,通过正交实验确定各组成菌株的最佳配比,制成复合微生物菌剂,根据营养需求添加KH2PO4作为助剂.摇瓶实验结果显示相对于只加活性污泥的处理体系,菌剂及助剂投加至活性污泥体系中能够提高处理效率82.14%,将配制的菌剂接种至预先投加活性污泥并稳定运行的SBR反应器后,显示投加菌剂的SBR反应器对炼油废水的处理效率高于对照实验,反应9h后,处理效率能够提高25.39%.
According to the analysis of refinery wastewater, high-efficiency microbe which can degrade alkane,benzene series, phenol were screened. The proportion of these microbe determined by orthogonal experiment. Microorganisms agent includes those microbe and KH2PO4, act as aid agent, based on nutritional requirements. Experimental result reveals that addition of microorganisms agent and aid agent can increase efficiency of 82. 14% in relation to addition of sludge. SBR experiment reveals that addition of microorganisms agent and aid agent can increase efficiency of 25.39 % in relation to sludge.
