摘要

摘要: 为探索植物-活性污泥复合系统(vegetation-activated sludge process,V-ASP)对邻苯二甲酸二甲酯(dimethyl phthalate,DMP)的去除效果,设置了50 mg/L、5 mg/L、500 μg/L、50 μg/L、0 μg/L 5个进水浓度梯度的DMP,考察V-ASP中常规污染物出水浓度、植物和微生物菌群的变化,以及其对DMP的去除作用。结果表明:DMP对V-ASP去除常规污染物的影响不大,仅在DMP浓度≥500 μg/L时可提升V-ASP对TN的去除效果。进水浓度DMP为50 mg/L、5 mg/L、500 μg/L和50 μg/L时在V-ASP中的去除率分别为99.97%、99.51%、94.19%和83.68%。DMP在V-ASP中的主要去除途径为微生物分解代谢,植物吸收占比不超过1.12%。当进水DMP浓度达到5 mg/L时,V-ASP中植物生长受到明显抑制。高通量测序结果显示,DMP会对V-ASP中活性污泥和根际污泥的微生物多样性产生一定影响。微生物群落中Proteobacteria(变形菌门)的相对丰度最高,Rhodococcus(红球菌属)的相对丰度随DMP浓度的升高而增加。

Abstract: To explore the removal of dimethyl phthalate (DMP) in a vegetation-activated sludge process (V-ASP), DMP with influent concentration gradients of 50 mg/L, 5 mg/L, 500 μg/L, 50 μg/L and 0 μg/L was set to investigate the effects of conventional pollutants effluent concentration, the changes of plant and microorganism and its removal efficiency. The results showed that DMP had little effect on the removal of conventional pollutants in V-ASP, and the removal efficiency of TN got improved when the concentration of DMP was greater than or equal to 500 μg/L. The removal rates of 50 mg/L, 5 mg/L, 500 μg/L and 50 μg/L DMP in V-ASP were 99.97%, 99.51%, 94.19% and 83.68%, respectively. The main removal pathway of DMP in V-ASP was found out to be microbial catabolism, and the proportion of DMP absorbed by plants was less than 1.12%. When the influent DMP concentration reached 5 mg/L, the plant in V-ASP was significantly inhibited. High-throughput sequencing results showed that DMP had a certain effect on the microbial diversity of activated sludge and rhizosphere sludge in V-ASP. The relative abundance of Proteobacteria was the highest in the microbial community, and that of Rhodococcus increased with the increase of DMP concentration.
