摘  要：
三唑类杀菌剂苯醚甲环唑生产废水具有高毒、高COD和氨氮含量、高盐分等特点,且其中含有苯醚甲环唑及中间体等对微生物有抑制作用的有机物,无法进行常规生化处理。根据废水特点,采用蒸发—铁碳微电解—Fenton氧化—厌氧—一级好氧—二级好氧—硝化/反硝化—絮凝沉淀组合工艺进行处理。结果表明:蒸发工艺可有效去除废水中的盐分和部分COD;铁碳微电解和Fenton氧化等预处理工艺可以将废水中苯醚甲环唑及其中间体等有机物降解或转化为小分子有机酸,提高了废水的可生化性;生化处理系统可以有效降低COD和氨氮含量。处理后,出水指标达到标准要求。

摘  要：
The wastewater of a fungicide factory exhibited the characteristics of high toxicity, high COD, high ammonia-nitrogen and high salinity. Especially, this wastewater contained difenoconazole and its intermediates which had inhibitory effects on microorganism. Therefore, it was unlikely to remove them by conventional biological treatment.According to these facts, a combined process of evaporation, ferric-carbon micro-electrolysis, Fenton oxidation, anaerobic,aerobic, nitrification, denitrification and flocculating deposition was employed to treat this wastewater. The results showed that the evaporation process could effectively remove the salt and the partial COD from wastewater. Further, the pretreatment of ferric-carbon micro-electrolysis and Fenton oxidation could converse the triazole fungicide into short-chain carboxylic acids. The biochemical system could effectively reduced the amounts of COD and ammonia-nitrogen. The effluent quality could comply with Integrated Wastewater Discharge Standard after the treatment.
