摘    要:采用铁碳微电解系统对ABS(丙烯腈-丁二烯-苯乙烯共聚物)凝聚干燥工段废水进行预处理,重点研究了不同进水pH值对铁碳微电解处理效果的影响.为了研究铁碳微电解系统分解转化有毒难降解有机物污染物的电化学作用,分别建立了活性炭对照实验和铁对照实验.结果表明,不同进水pH值条件下,微电解处理后出水的TOC去除率均在40%~60%之间;微电解能够分解转化废水中的有毒难降解有机污染物,使废水的BOD5/COD值由0.32提高到0.60以上,极大地提高了废水的可生化性;在进水pH值为4.0的条件下,微电解处理出水的BOD5/COD值高达0.71,且进水pH值为4.0的条件下微电解对废水中有机污染物的分解转化效率最高.因此,铁碳微电解系统的最佳进水pH值为4.0.

关 键 词:ABS废水  铁碳微电解  可生化性  pH值  芳香类化合物  有机腈类

Abstract:Wastewater from the condensation and drying section of acrylonitrile-butadiene-styrene(ABS) resin plant was pretreated by the microelectrolysis, and the effect of the influent pH value on the pollution removal efficiency of the microelectrolysis was mainly studied. In order to study the electrochemical action of the microelectrolysis for the degradation of toxic refractory organic pollutants, two control experiments of activated carbon and iron were set up.The results showed that the TOC removal efficiencies were all fluctuated between 40% and 60% under the condition of different influent pH values. The microelectrolysis can decompose and transform the toxic refractory organic pollutants and increase the BOD5/COD ratio from 0.32 to 0.60, which increased the biodegradability of ABS resin wastewater significantly. When the pH value of influent was 4.0, the BOD5/COD ratio of effluent reached 0.71. The result of UV-vis spectra indicates that the removal efficiency of the organic nitrile was the highest with influent pH was 4.0. Therefore, the best influent pH value of microelectrolysis was 4.0.
Keywords:ABS resin wastewater  microelectrolysis  biodegradability  pH value  aromatic compounds  organic nitriles
