这项研究的重点是在二级处理废水(STWW)中通过生物工艺去除五氯苯酚的潜力。拟议的过程是使用本地植物进行植物修复的组合方法,Polypogonmaritimus和Lemna小调,和使用真菌的生物强化。生物强化过程是通过能够去除PCP的真菌分离物进行的,与堆肥隔离。真菌的鉴定是通过形态学进行的,生物化学,和分子方法。建立了通过生物强化和植物修复的生物处理系统,以评估该过程消除高浓度PCP的能力。物理化学参数,如pH值,COD,COD在实验时间T0(初始)和Tf(最终)测试BOD。通过HPLC方法控制PCP的浓度。因此,通过分光光度法测定真菌的生长,并在琼脂培养基上进行计数。获得的结果表明,分离和选择的真菌是由伊尔丹青霉菌鉴定的。所使用的真菌菌株具有显著的耐受和消除PCP的能力。理化参数的结果表明,处理后的废水质量有所改善。PCP的消除伴随着普通法的发布-以及STWW中DOC值的重要降低。获得的结果表明,Polypogon处理显示PCP的显著消除,百分比约为92.01%和23.58g。L-1氯化物浓度。随着叶绿素的增加及其更长的片层,所使用的大型植物表现出更好的耐受和消除PCP的能力。

This study focused on the potential for pentachlorophenol removal by a biological process in secondary treated wastewater (STWW). The proposed process is a combined method of phytoremediation using a native plant, Polypogon maritimus and Lemna minor, and
bioaugmentation using a fungus. The
bioaugmentation process was performed by a fungal isolate capable of removing PCP, isolated from the compost. The identification of the fungus was performed by morphological, biochemical, and molecular methods. A biological treatment system by
bioaugmentation and phytoremediation was set up to estimate the capacity of this process to eliminate a high concentration of PCP. physico-chemical parameters, such as pH, COD, and BOD were tested at experimentation times T0 (initial) and Tf (final). The concentration of PCP is controlled by the HPLC method. Thus, the growth of the fungus was determined by spectrophotometry and enumeration on the agar medium. The results obtained show that the isolated and selected fungus is identified by Penicillium Ilerdanum. The fungal strain used has a significant capacity for tolerance and elimination of PCP. The results of the physico-chemical parameters showed an improvement in the quality of wastewater after the treatment was carried out. The elimination of PCP came with a release of Common law- and an important decrease in the DOC value in the STWW. The results obtained show that the Polypogon treatment shows a significant elimination of PCP by a percentage of the order of 92.01% and 23.58 g. L- 1 chloride concentration. The macrophytes used showed a better ability to tolerate and eliminate PCP with an increase of chlorophyll and its longer sheets.
