In this research the process performance of enhanced biological phosphorus removal was investigated in a sequencing batch reactor (SBR) having a new operational mode. The SBR system used in this study had simultaneous feeding and decanting conditions. The laboratory scale reactor (10 L) was operated for 392 days. The system was operated under 4 different sets each having 2 cycles per day. In each cycle, fill (4 h), anoxic (0.5 h), aerobic (7 h) and settling phases were present. In the fill phase, wastewater was fed from the bottom and the anoxic/anaerobic conditions were established in the settled sludge. During filling, the water left the system by water displacement. The system provided nitrification, denitrification as well as phosphorus and organic removal. High COD (90-98%), PO4-P (77-100%), and NH4-N (90-95%) removals were achieved by this system.
在本研究中，在具有新运行模式的序批式反应器（SBR）中研究了强化生物除磷的工艺性能。本研究中使用的SBR系统具有同时进水和排水的条件。实验室规模的反应器（10升）运行了392天。该系统在4种不同的工况下运行，每种工况每天有2个周期。在每个周期中，存在进水（4小时）、缺氧（0.5小时）、好氧（7小时）和沉淀阶段。在进水阶段，废水从底部进入，并在沉淀污泥中建立缺氧/厌氧条件。进水期间，水通过排水作用离开系统。该系统实现了硝化、反硝化以及磷和有机物的去除。该系统实现了较高的化学需氧量（COD）去除率（90 - 98%）、磷酸根磷（PO4 - P）去除率（77 - 100%）和氨氮（NH4 - N）去除率（90 - 95%）。
