摘　　要：阐述了间歇膨胀复合厌氧反应器的特点和设计运行参数,并以印染废水为例进行应用研究。考察了水解停留时间HRT为12 h的条件下,接触氧化15 h,水解反应器与接触氧化反应器COD及色度的去除效果。结果表明:进水COD为1000~1300 mg/L、色度为100~300倍的条件下,生化出水COD、色度分别为150~160 mg/L、50~80倍,出水完全满足GB 4287—2012《纺织染整工业水污染物排放标准》中表2间接排放限值要求。The characteristics and design parameters of intermittent expansion composite anaerobic reactors are described.The removal efficiency of COD and chromaticity in the hydrolysis reactor and contact oxidation reactor under the conditions of hydrolysis retention time(HRT)of 12 h and contact oxidation time of 15 h is investigated taking the printing and dyeing wastewater as an example.The results show that under the conditions of influent COD 1000-1300 mg/L and chromaticity 100-300 times,the biochemical effluent COD and chromaticity are 150-160 mg/L and 50-80 times,respectively.The effluent can meet the indirect emission limit requirements in Table 2 of the Textile Dyeing and Finishing Industry Water Pollutant Discharge Standard(GB 4287—2012).
