摘要: 传统生化法对印染废水的处理有一定的局限性。本文研究了双氧水协同水解酸化-接触氧化系统,对印染废水进行强化处理。采用污泥挂膜、生化系统启动、双氧水协同启动的方法,将双氧水投加到水解酸化时的条件严格控制为:投加浓度3 mL·L-1、投加量100.0 mL、流速0.67 mL·min-1、投加频率1次·d-1,可使整个系统成功启动与稳定运行。实验结果表明,双氧水协同水解酸化-接触氧化可对印染废水中的特征污染物进行有效强化处理。其中,COD平均去除率为89.8%,氨氮平均去除率为96.7%,PVA平均去除率为87.4%,废水平均脱色率为92.1%。采用16S rDNA宏基因组高通量测序技术,对比分析了...
英文摘要: The traditional biochemical treatment of printing and dyeing wastewater has a limited ability. This experiment investigated that H2 O2 could strengthen the biological ability of hydrolytic acidification/ biological contact oxidation process (A/O), which effectively treat the printing and dyeing wastewater. After biofilm formation, biochemical system startup and biochemical system operation cooperated by H2 O2 , this system successfully started-up and steadily operated when H2 O2 was added into reactor A in the conditions of H2 O2 concentration for 3 mL•L -1 , doses for 100.0 mL, flow velocity for 0.67 mL•min -1 and dosing frequency for once a day. The experimental results showed that the average removal efficiencies of COD, ammonia nitrogen, PVA and color for printing and dyeing wastewater were 89.8%, 96.7%, 87.4% and 92.1%, respectively. The microorganism community structures of reactor A and reactor O in this system were researched by high-throughput sequencing of 16S rDNA amplicon. The results demonstrated that the three dominant microbial strains in reactor A were Proteobacteria, Bacteroidetes and Verrucomicrobia. The three dominant microbial strains in reactor O were Planctomycetes, Proteobacteria and Acidobacteria.
