摘要

摘要: 江苏某化工园区发生爆炸，造成周边河道积聚大量高苯胺河水，该类受污染河水具有较高的活性污泥抑制性，需在进入园区污水处理厂应急处理前进行脱毒预处理。研究对比了芬顿氧化法、活性炭吸附法和生物处理法对受污染河水的预处理效果。结果表明，芬顿氧化法处理效率较高、运行成本中等，且现场处理设施易于改造利用，最终被选为高苯胺河水的脱毒预处理工艺。实际应急处置工程运行效果表明，芬顿氧化预处理实现了重污染河水中苯胺类的有效去除，在苯胺类浓度为30~90 mg/L的情况下，批次出水苯胺类浓度基本稳定在1 mg/L以下，保证了园区污水处理厂的稳定运行，最终实现其出水达标。

Abstract: An explosion occurred in a chemical industry park in Jiangsu Province, causing a large amount of high-aniline river water to accumulate in the surrounding rivers, which had high inhibition against activated sludge. Detoxification pretreatment was needed before the polluted river water entered the park wastewater treatment plant for emergency treatment. The pretreatment effects of Fenton oxidation, activated carbon adsorption and biological treatment on the polluted river water were studied and compared. Fenton oxidation method had high treatment efficiency, medium operation cost and the on-site treatment facilities were easy to transform and utilize; finally, it was selected as the detoxification pretreatment process of the high-aniline river water. The operation of the actual emergency treatment project showed that Fenton oxidation pretreatment realized effective aniline removal from the heavily polluted river water. In the fluctuated aniline concentration of 30-90 mg/L, the effluent aniline concentrations of the batch tests was basically stable below 1 mg/L, which ensured the stable operation of the park wastewater treatment plant, and finally the effluent met the discharge standard.
