A system which combined ASBR with pulsed SBR (PSBR) was introduced to enhance COD and nitrogen removal from the real landfill leachate. ASBR was used to degrade the organics from raw leachate mainly. Three equal feeds mode was applied in PSBR operation. The results obtained from the joint operation period (157 days) show that the COD removal rate of ASBR was 83-88% under the specific loading rate of 0.43-0.62 gCOD gVSS(-1) day(-1). PSBR's operation can be divided into four phases according to the different influent NH(4)(+)-N which increased to 800-1000 mg L(-1) finally, and total nitrogen (TN) removal rate of more than 90% with the effluent TN of less than 40 mg L(-1) was obtained. PHB and glycogen can act as electron donor for endogenous denitritation orderly with the hypothetical function from DNGAOs. Consequently, the system achieved COD and TN removal rate of 89.61-96.73% and 97.03-98.87%, respectively, without any extra carbon source addition.
一种将 ABSTR 与脉冲式 SBR（PSBR）结合的系统被引入，以提高从实际垃圾渗滤液中去除 COD 和氮的效果。ABSTR 主要用于降解原渗滤液中的有机物。PSBR 操作采用三相等分进料模式。联合运行期间（157 天）的结果表明，在特定负荷率为 0.43-0.62 gCOD gVSS(-1) day(-1)时，ABSTR 的 COD 去除率为 83-88%。PSBR 的运行可以根据不同的进水 NH(4)(+) -N 分为四个阶段，最终进水 NH(4)(+) -N 增加到 800-1000 mg L(-1)，总氮（TN）去除率超过 90%，出水 TN 低于 40 mg L(-1)。PHB 和糖原可以作为电子供体，用于顺序进行内源反硝化，假设功能来自 DNGAOs。因此，该系统在不添加任何额外碳源的情况下，分别实现了 89.61-96.73%和 97.03-98.87%的 COD 和 TN 去除率。
