| 摘 要： | 为了分解转化ABS树脂生产废水中的难降解有毒污染物并提高废水的可生化性，采用铁炭微电解系统对废水进行预处理，并利用三维荧光光谱快速检测分析废水中芳香类污染物的分解转化。结果表明，在进水pH为4.0条件下，铁炭微电解系统连续稳定运行30 d后，ABS废水CODCr和总荧光强度的去除率分别为53.27%和73.45%。进水pH直接影响废水CODCr去除率，其对CODCr去除率的影响由高到低依次为：pH=4.0，pH=6.0，pH=8.0。但是总荧光强度的去除率不符合该规律，不同进水pH条件下，总荧光强度去除率为73.45%~74.88%，即进水pH对铁炭微电解反应器分解转化芳香类化合物的影响较小。

| Abstract: | In order to decompose and transform the toxic refractory typical pollutants from Acrylonitrile-Butadiene-Styrene (ABS) resin wastewater and improve the biodegradability of the wastewater, the wastewater was pretreated by the ferric-carbon micro-electrolysis. The decomposition and transformation of the aromatic pollutants from ABS wastewater was detected rapidly by three-dimensional fluorescence spectra technology. The results showed that under the condition of influent pH 4.0, the removal efficiency of CODCr and total fluorescence intensity was 53.27% and 73.45%, respectively, after 30 days of continuous and stable run of mico-electrolysis. The removal efficiency of CODCr was affected directly by the influent pH. The CODCr removal efficiency of three micro-electrolysis reactors with different influent pH in sequence was as follows: pH=4.0＞pH=6.0＞pH=8.0. However, the removal efficiency of total fluorescence intensity did not comply with this law. The removal efficiency of total fluorescence intensity was all between 73.45% and 74.88% with different influent pH. In other words, the effect of influent pH on the degradation or transformation of aromatics by the ferric-carbon micro-electrolysis reactors was small. |
