SBR technology is used to treat the supernatant from mesophilic anaerobic digestion of piggery wastewater. The novelty of the treatment consists in the use of a final coagulation/flocculation step inside the SBR cycle to reach the legal COD effluent standard. The pH changes introduced by the use of FeCl(3) do not affect the nitrifying activity. The SBR treatment includes a strategy to the control of oxygen supply and ammonia concentrations inside the digester to favor the biological nitrogen removal over nitrite, which makes the process more economical. The influence of several of these parameters on the AOB biomass activity is studied in this paper.
序批式反应器（SBR）技术用于处理猪场废水嗜温厌氧消化后的上清液。该处理方法的新颖之处在于在SBR循环中采用最终的混凝/絮凝步骤，以达到合法的化学需氧量（COD）排放标准。使用三氯化铁（FeCl₃）引起的pH值变化不会影响硝化活性。SBR处理包括一种控制消化器内氧气供应和氨浓度的策略，以利于生物脱氮生成亚硝酸盐，这使得该过程更经济。本文研究了其中几个参数对氨氧化细菌（AOB）生物量活性的影响。
