水解酸化-BioDopp工艺处理印染废水的中试研究
|
摘要
采用水解酸化-BioDopp组合工艺进行中试处理,探讨了系统处理印染废水的效果及稳定性。结果表明,系统的出水COD从1 172 mg/L左右降到了100 mg/L以下,氨氮质量浓度从32 mg/L左右降到了15 mg/L以下,平均去除率分别约为92.1%和88.6%,出水水质符合纺织染整工业水污染物排放标准(GB 4287-92)中一级标准,同时系统内存在同步硝化反硝化作用,对TN的去除率可达76.2%左右。
In this work, a pilot-scale wastewater treatment was tested for printing and dyeing wastewater from a textile factory. The wastewater was treated through the hydrolysis acidification-BioDopp process. The treatment efficiency of printing and dyeing wastewater and stability of the system were also explored in this paper. The results showed that the average concentrations of COD and ammonia nitrogen in the effluent were less than 100mg/L and 15 mg/L. The average COD and ammonia nitrogen removal efficiencies were 92.1% and 88.6%. The treated effluent quality met the first grade criteria specified in discharge standard of water pollutants for dyeing and finishing of textile industry(GB 4287-92). Moreover, as the simultaneous nitrification and denitrification existed in the reactor, the average total nitrogen removal efficiency was 76.2%.
