“…The removal of COD was primarily affected by the toxicity of the leachate. Li et al [34] used a modified Bardenpho process with an upward-flowing anaerobic sludge bed for leachate treatment. The results showed that it is feasible to dilute the leachate by recirculating wastewater from the sedimentation tanks, which is important for the efficiency of the biological treatment.…”

The garbage leachate generated by the waste transfer station has the characteristics of scattered water sources, relatively small water quantity, large fluctuations in water quality and quantity, and high concentrations of organic matter, ammonia nitrogen, suspended solids, and other pollutants. These characteristics make it prone to environmental hazards. This paper analyzes the characteristics and hazards of leachate from waste transfer stations and introduces the current research status of physico-chemical, biological, and combined treatment of leachate from waste transfer stations. Meanwhile, this paper introduces engineering practices for leachate treatment in waste transfer stations, offering a valuable reference for research and engineering practices in this field. Finally, this review discusses pretreatment, economic, low-carbon, and high-efficiency treatment methods and facilities, the recovery of valuable elements, energy recycling technologies, and the demand outlook for high-standard deep treatment processes.

“…Therefore, landfill leachate has become one of the most important issues in sustainable landfill solid waste management due to the increasingly stringent requirements for controlling contamination and the problems encountered for its treatment; and the effective treatment, of especially freshly produced leachate (in the early stages of waste disposal or decomposition) has received more attention around the world. Therefore, sustainable economic and environmental solutions for treating this highly polluting wastewater are at increasing demand [5,6].…”

Purpose A bioelectricity producing system was configured by connecting to a microbial electrolysis cell producing hydrogen, in which both systems were without mediator, to treatment the landfill leachate of the and generate bioelectricity and hydrogen. Methods The anode electrode was made with MWCNTs polyscale coating on graphite felt and the cathode electrode with activated carbon coating on carbon cloth. In the MFC-MEC coupled system, the electrodes were connected in series using copper wire. The system was set up in a fed-batch mode and the landfill synthetic leachate was injected into the anode MFC-MEC chamber as fuel. ResultsIn MFC, the highest voltage, current density and power density were 1114 mV, 44.2A/m 3 and 49.24 W/m 3 , respectively. The maximum of the coulombic efficiency system was 94.10%. The highest removed COD, NH 4 -N and P was 97.38%, 79.56% and 74.61%, respectively. In the MEC, the maximum of voltage input, current density and power density was 1106 mV, 43.88 A/m 3 and 48.54 W/m 3 , respectively. The maximum coulombic efficiency system was 125.54%. Also the highest removed COD, NH 4 -N and P was 97.46%, 78.81% and 76.25%, respectively. The highest biogas production rate and its yield were 39 mL/L.d, and 0.0118 L/g CODrem, respectively. Conclusion This study found that the MFC-MEC coupled system had promising potential for strong wastewaters treatment, such as the leachate of landfill; and the in-site use of generated electricity and the production of useful fuels such as biogas.

This paper deals with the kinetics of microbial cell growth, utilization of organic substrates and methane production in upflow anaerobic filters in two and three separated stages (UAF‐2SS and UAF‐3SS) treating sanitary landfill leachates, under three temperatures (20, 27, and 34°C), fed with volumetric organic loads (VOLs) for UAF‐2SS (1.8, 2.25, 2.76, 3.45, 3.71, 4.64 kgCOD (chemical oxygen demand)/m3/d) and UAF‐3SS (1.7, 2.25, 2.44, 2.6, 3.15, 3.45, 3.5, 4.57, 4.64, 6.31, 11.61, 14.18, 17.48 kgCOD/m3/d). Kinetic parameters were obtained at temperature (20–34°C), pH (8.8–9.1), each one of three stages within the UAF‐2SS and UAF‐3SS reactors containing methanogenic bacteria (Methanococcus sp., and Methanobacterium sp.) and Clostridium sp.: Maximum substrate utilization rate (rm,s) resulted in 102 mg COD/L/h, maximum microbial cell growth rate (μm) varied 102–103 CFU (colony forming units)/mL/h, methane (CH4) production rate (rm,CH4) tended to vary 100–101 mg CH4/d and the maximum production coefficient (Y) varied 0–102 CFU/mL/h/mgCOD/L/h.
