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.

引入了一种将ASBR与脉冲SBR (PSBR) 相结合的系统，以提高实际垃圾渗滤液中COD和氮的去除。ASBR主要用于降解原渗滤液中的有机物。PSBR操作中采用了三等馈模式。联合运行期 (157天) 获得的结果表明，在0.43-0.62 gCOD gVSS(-1) 天 (-1) 的比载率下，ASBR的COD去除率为83-88%。PSBR的操作可根据不同的进水NH(4)(+)-N分为四个阶段，最后增加到800-1000 mg L(-1)，当出水TN小于40 mg L(-1) 时，总氮 (TN) 去除率大于90%。PHB和糖原可以作为内源性脱氮的电子供体，具有DNGAOs的假设功能。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。
