好氧颗粒污泥实现同步除磷脱氮的试验研究
Study on Simultaneous Phosphorus and Nitrogen Removal through Aerobic Granular Sludge
【摘要】 在厌氧反应1h,好氧反应4h,缺氧反应2h的运行条件下,研究了序批式反应器中好氧颗粒污泥同步除磷脱氮的情况,并对好氧颗粒污泥除磷脱氮的机理进行了探讨.试验结果表明,该系统对氮、磷和有机物具有良好的去除效果,对氨氮、总无机氮、磷、COD的去除率分别达到89.2%~98.9%,81.3%~89.4%,86.8%~90.0%和82.7%~96.6%.
【Abstract】 <Abstrcat>Simultaneous phosphorus and nitrogen removal through aerobic granular sludge was achieved in a SBR system under the conditions of anaerobic reaction time 1 h, aerobic reaction 4 h and anoxic reaction 2 h. This SBR system showed a very stable phosphorus, nitrogen and organic carbon removal performance. The removal rate for ammonium, total inorganic nitrogen, phosphorus and organic carbon reached 89.2%~98.9%,81.3%~89.4%,86.8%~90.0% and 82.7%~96.6% respectively.
