Abstract:

Landfill leachate has the characteristics of high ammonia nitrogen content, high concentration of organic matter and low carbon nitrogen ratio. Traditional biological treatment technology is difficult to meet the increasingly stringent emission standards. Ammonia nitrogen is the main pollutant in landfill leachate. The ammonia-nitrogen-rich leachate not only poses a threat to the surrounding environment, but also has adverse effects on the subsequent biological treatment of leachate. Anaerobic ammonium oxidation (Anammox) is a new biological denitrification technology, which has the advantages

Abstract:

With the development of economy and the improvement of people’s living standard, landfill leachate has been increasing year by year with the increase in municipal solid waste output. How to treat landfill leachate with high efficiency and low consumption has become a major problem, because of its high ammonia nitrogen and organic matter content, low carbon to nitrogen ratio and difficult degradation. In order to provide reference for future engineering application of landfill leachate treatment, this paper mainly reviews the biological treatment methods of landfill leachate, which focuses on t

Abstract:

Abstract Three management options for the treatment of leachate from landfilled domestic solid waste have been evaluated. Research results show that leachate can be treated effectively in aerobic systems, with high organic carbon and ammoniacal nitrogen removals of &gt;90% and &gt;85% respectively. Optimum SRT of about 10 days is required. Anaerobic treatment (UASB) with HRT's of between 1.0 and 4.0 days results in COD destruction of about 85% with high methane production (400-600 mg/g COD removed) and provides an intermediate effluent suitable for polishing to a high standard.

The microorganism-attached activated carbon fluidized bed (MAACFB) process was applied to treat a landfill leachate containing refractory organics and a high concentration of ammonium nitrogen. The MAACFB process removed about 60 % and 70 % of refractory organics and nitrogen, respectively, from the landfill leachate simultaneously and steadily over a more than 700 days of operation period. A mass balance on organics around the MAACFB process revealed that more than 90 % of the removed organics may be biodegraded.

Abstract:

Mature landfill leachate is a complex and highly polluted effluent with a large amount of ammonia nitrogen, toxic components and low biodegradability. Its COD/N and BOD5/COD ratios are low, which is not suitable for traditional nitrification and denitrification processes. Anaerobic ammonia oxidation (anammox) is an innovative biological denitrification process, relying on anammox bacteria to form stable biofilms or granules. It has been extensively used in nitrogen removal of mature landfill leachate due to its high efficiency, low cost and sludge yield. This paper reviewed recent advances of

The management of the liquid fraction of digestate produced from the anaerobic digestion of biodegradable municipal solid waste is a difficult affair, as its land application is limited due to high ammonium concentrations and the municipal waste that water treatment plants struggle to treat due to high pollutant loads.

One of the most economical means of nitrogen removal from leachate is biological treatment by nitrification, followed by heterotrophic denitrification. An alternative biological denitrification process is autotrophic denitrification using Thiobacillus denitrificans. This autotrophic bacteria oxidizes elemental sulphur to sulphate while reducing nitrate to elemental nitrogen gas, thereby eliminating the need for addition of organic carbon compounds. For this study, pilot-scale elemental sulphur packed bed columns with fixed-film denitrification have been selected as the most suitable treatment

Abstract:

This research focused on the inhibitory effects of Ca on the aerobic biological treatment of landfill leachate containing extremely high Ca concentrations. When the Ca concentration in leachate to be treated was more than 4500 mg l−1, the total organic carbon removal rate was significantly reduced and the processing time to achieve the same removal efficiency was 1.4 times that in the control treatment without added Ca. In contrast, the total nitrogen and ammonia nitrogen (NH4+–N) removal efficiencies were positively related to the Ca concentration, increasing from 65.2% to 81.2% and from 69.2

Abstract:

Micro-peat (M-P) was demonstrated in the present study as a potential low cost natural adsorbent for the removal of COD and ammoniacal nitrogen (NH3-N) from landfill leachate. A series of batch experiments were carried out under fixed conditions and the influence of mixture ratio was investigated. The characteristics of leachate were then determined. Results indicated that leachate is non-biodegradable with high concentration of COD (2739.06 mg/L), NH3-N (1765.34 mg/L) and BOD5/COD ratio (0.09). The optimum ratio for activated carbon (AC) and M-P in the removal of COD and NH3-N obtained were a

Electrochemical technologies have been broadly applied in wastewaters treatment, but few studies have focused on comparing the performance of the different electrochemical processes, especially when used to treat highly-polluted streams. The electrochemical treatment of a reverse osmosis concentrate of sanitary landfill leachate was performed by means of electrocoagulation (EC), anodic oxidation (AO) and electro-Fenton (EF) processes, and the use of different electrode materials and experimental conditions was assessed.

Biological nitrogen removal via Anammox is an advantageous technology in the nitrogen treatment effluents with a low Carbon/Nitrogen ratio, a process that makes this route interesting for the most different types of industries, agribusinesses, and urban effluent treatment plants. Achieving robust Anammox biomass for use in full-scale plants is still a challenge that motivates studies of biomass enrichment and the search for kinetic parameters of substrate consumption rate that help optimize the conduction of reactors.

An advanced nitrogen removal pilot study was performed in China's Xia Ping Landfill Leachate Treatment Plant to undertake shortcut nitrification and denitrification with the Membrane Bio-reactor (MBR) process. It was found that the MBR process used 25% less of the oxygen and 40% less of the external carbon sources, compared to the conventional nitrification and denitrification process. The key feature of the MBR process is that it provides an environment more favorable for ammonia oxidation bacterium (AOB) than for nitrite oxidation bacterium (NOB) through controlling loading, pH, temperature,
