复合生物处理技术在SBR中的应用

Application of Composite Biological Technology on Sequencing Batch Reactor

近年来的研究结果表明,通过向传统SBR污水处理工艺投加生物悬浮流化填料或腐殖土等生物活性填料,利用复合生物处理技术,在创造系统内生物附着载体的环境条件下,增加和丰富了生物量及各种微生物菌群的种类,改善了活性污泥的生物性能,构成相对稳定的固着式生长和悬浮式生长的复合生物处理体系,可明显提高COD、氨氮、总氮、总磷的去除率,增强SBR的除污效果,并可避免污泥膨胀问题的出现,进而提高处理系统的净化效率及出水水质。采用这种技术方法,操作简便易行,对于进一步提升SBR的污水处理效能具有重要的作用和较高的研究价值,是一种有广阔研究应用前景的污水生物处理技术。

In recent years a number of research results show that using composite biological treatment technology, like adding biological fluidized media or humus soil media in the traditional SBR, in the condition of the area of biofouling, the biomass and microbial species is on the rise. In the meantime, using the microorganisms of humus soil can improve the performance of activated sludge and the efficiency of removing the COD, NH4＋-N, TN and TP in the traditional SBR. Above all, the occurrence of sludge bulking problem is avoided and water quality will be better. Therefore, the research in using composite biological technology in sequencing batch reactor to improve sewage treatment efficiency is of great significance and has a broad application prospect research of sewage biological treatment technology.
