Abstract:
The treatment process of the actual organic silicon wastewater by the iron-carbon microelectrolysis+A/O combined process was investigated. The results show that the iron-carbon microelectrolytic degradation complies with the first-order reaction kinetics. The combined process has a total COD removal rate of 96%, and the effluent reaches the first-class standard of Integrated Wastewater Discharge Standard(GB 8978-1996). It indicates that the combined process has the ability to run stably. Three-dimensional fluorescence analysis shows that there are peaks A and B which are difficult to degrade in raw water, and peaks C and D which are easy to degrade after microelectrolysis and anaerobic treatment. In the final effluent, only peak B with the same intensity as the raw water remains.

摘要:
考察了铁碳微电解+A/O组合工艺对实际有机硅废水的处理过程。结果表明,铁碳微电解降解符合一级反应动力学;组合工艺对COD总去除率达到了96%,出水达到《污水综合排放标准》(GB 8978—1996)表4的一级标准,说明该组合工艺具备稳定达标运行的能力。三维荧光分析表明,原水中存在难降解峰峰A、峰B,微电解和厌氧处理后出现了易降解峰峰C和峰D,最终出水中仅保留与原水强度相当的峰B。
