Abstract：The wastewater from garbage transfer stations has thecharacteristics of highconcentrationoforganic polutants， highammonia nitrogencontent，and strong waterqualityfluctuations.Traditionaltreatment procesesare dificult to meet the equirementsof eficientandstable treatment.Theapplicationofeficientanaerobic biological treatment technologyis studied in the treatmentofwaste waterin garbage transferstations，the treatment mechanismandapplicabilityof diferent anaerobic reactors are analyzed，such as Upflow Anaerobic Sludge Bed （UASB），anaerobic Expanded Granular Sludge Bed （EGSB）， Internal Circulation （IC）anaerobicreactor，the key technologies are explored such as pretreatment，start-up control，and methaneproductionstage optimization，andthetreatment efect，gas productionate，andoperating costsare analyzed basedonengineringcases.Research has shown that eficient anaerobic processes have good removaleffects on Chemical Oxygen Demand （COD）， Biochemical Oxygen Demand （BOD），and ammonia nitrogen，andoptimizing the methane productionstagecan improve energyrecoveryrates，andoveralloperation isstable andeconomicallyfeasible.The promotion andapplicationofthis processcan effectivelyreduce thepolutionloadofwastewater ingarbage transferstations，achieve resource utilization，and have important environmental and economic value.

垃圾中转站在城市固体废物收运过程中发挥重要作用，但其运行过程产生的废水具有有机污染物浓度高、氨氮含量大、水质波动性强的特点，如果没有进行有效的处理就直接排放，将对环境造成严重污染。（剩余3594字）
