Abstract
The wastewater from garbage transfer stations has the characteristics of high concentration of organic pollutants,high ammonia nitrogen content,and strong water quality fluctuations.Traditional treatment processes are difficult to meet the requirements of efficient and stable treatment.The application of efficient anaerobic biological treatment technology is studied in the treatment of waste water in garbage transfer stations,the treatment mechanism and applicability of different anaerobic reactors are analyzed,such as Upflow Anaerobic Sludge Bed(UASB),anaerobic Expanded Granular Sludge Bed(EGSB),Internal Circulation(IC)anaerobic reactor,the key technologies are explored such as pretreatment,start-up control,and methane production stage optimization,and the treatment effect,gas production rate,and operating costs are analyzed based on engineering cases.Research has shown that efficient anaerobic processes have good removal effects on Chemical Oxygen Demand(COD),Biochemical Oxygen Demand(BOD),and ammonia nitrogen,and optimizing the methane production stage can improve energy recovery rates,and overall operation is stable and economically feasible.The promotion and application of this process can effectively reduce the pollution load of wastewater in garbage transfer stations,achieve resource utilization,and have important environmental and economic value.关键词
