摘要
应用"两级上流式厌氧污泥床(UASB)-缺氧/好氧(A/O)-序批式反应器(SBR)系统"深度处理实际晚期垃圾渗滤液,研究在A/O反应器中实现并维持稳定短程硝化的影响因素。该系统按如下模式运行:首先在一级UASB(UASB1)中实现反硝化,残余亚硝态氮和硝态氮利用剩余COD(化学需氧量)在二级UASB(UASB2)中通过反硝化被进一步去除,之后在A/O反应器的好氧区进行NH4+-N的硝化,最后在SBR中去除硝化产生的亚硝态氮及硝态氮深度脱氮。试验结果表明:原渗滤液COD质量浓度仅3.00 g/L左右,氨氮质量浓度在2.00 g/L左右;系统进水采用将原渗滤液与生活污水1:1混合液,且投加相当于1.56 g/L COD的外碳源无水乙酸钠,将C和N质量浓度比由1.7提高到3.0;通过FA与FNA对NOB的联合抑制,在A/O反应器中实现了稳定的短程硝化,其中亚硝态氮积累率大与70%;产生的亚硝态氮和硝态氮在SBR中被彻底去除;最终出水氨氮质量浓度小于2 mg/L,氨氮的去除率为99%;最终出水总氮质量浓度为26 mg/L,系统总氮去除率接近98%。
