摘　　要：为了分解转化丙烯腈-苯乙烯-丁二烯的聚合物(ABS)树脂生产废水中的有毒难降解污染物并提高废水的可生化性,采用铁炭微电解法对该废水进行预处理的研究,并利用傅里叶红外光谱(FTIR)检测分析了废水中特征污染物的分解转化。结果表明在进水pH值为4.0的条件下,微电解法能够高效地分解转化废水中的苯乙烯、二苯异丙醇、苯乙酮、2-氰基乙醚及双(2-氰基乙基)胺等主要特征污染物,生成不饱和脂肪酸、醇类及酰胺类易生化处理的小分子有机物。经微电解处理后,废水的BOD/COD值由0.32提高至0.71,极大地提高了废水的可生化性。In order to decompose and transform the toxic refractory typical pollutants from ABS resin wastewater, this wastewater was pretreated by the micro-electrolysis. The decomposition and transformation of the typical pollutants from ABS wastewater was detected by Fourier transform infrared （FTIR）. The results show that those typical pollutants, such as acrylonirile, styrene, alpha, alpha-dimethyl-benzenemethanol, acetophenone, 3,3＇-oxybis- propanenitrile and 3,3＇-iminobis-propanenitrile, could be decomposed and transformed by the micro-electrolysis under the condition of the influent pH value of 4. 0. The degradation products of those typical pollutants were small molecule organic compounds such as unsaturated fatty acids, alcohols or acylamides. And the BOD/COD ratio of ABS resin wastewater was increased from 0.32 to 0.71 after the treatment of micro-electrolysis, in other words, the biodegradability of ABS resin wastewater was increased significantly.
