  • 摘要: 在小型处理系统中生物除磷同步化学除磷简便易行，但加入的除磷剂本身和形成的化学沉淀物的积累可能会对生物系统造成影响。采用序批式生物反应器，对铁盐的2种投加剂量下对活性污泥系统的影响进行了研究。结果表明，向SBR系统中连续投加15 mg·L-1三氯化铁，表观上系统总体的除磷效率较未投加前有一定幅度的提高，活性污泥的沉降性能得到改善，但这削弱了系统的内在生物除磷效力。随着化学除磷的进行，系统污泥胞内PHA含量减少、糖原含量增加；污泥中PAOs相对数量下降而GAOs的相对数量显著增加，优势菌发生演替。结束投加后，污泥的活性可以缓慢恢复。说明该浓度下长时间连续进行同步化学与生物除磷，会对系统造成一定的损害，但这种损害在停止化学除磷后具有一定的可恢复性。而连续投加3 mg·L-1三氯化铁的SBR系统总体除磷效率较未投加前有所提高，且没有对生物除磷系统产生明显抑制作用，能够较好实现化学除磷和生物除磷的协同。
    Abstract: Biological treatment combined with chemical phosphorus removal is simple and convenient for a small-scale wastewater treatment system,but the chemical flocculant and sediment accumulated may have an influence on the microbes in the system.In this study,two laboratory-scale sequencing batch reactors (SBRs) were used to investigate the effects of feeding 3 mg·L-1 and 15 mg·L-1 ferric ions from FeCl3 on the biological phosphorus removing capacity of the activated sludge system.The results indicate that the removal efficiency of phosphorus increased to some extent after the ferric ion additions and the sedimentation performance of activated sludge improved,but this resulted in the weakening of the inherent biological phosphorus removal ability of the system to some extent.With the changes in performance following the feeding,the intracellular PHA content decreased while glycogen content increased.The population of PAOs declined while GAOs increased in the sludge;thus,predominant functional bacteria succession occurred.The results imply that the influences of FeCl3 feeding on activated sludge systems will be proportional to the concentrations used,i.e.,the effect will be more significant when the concentration is greater.The activity of the sludge was slowly recovered after the dosing ended.The simultaneous changes in chemical phosphorus precipitation and biological phosphorus removal will bring about some deterioration to the activated sludge system for a lengthy period of time,but these activities can be recovered.
