Characterization and electrocaogulative treatment of nanofiltration concentrate of a full-scale landfill leachate treatment plant

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, dissolved oxygen concentration (DO), and NH3 inhibition. Optimum operating condition was examined through continuous running of the pilot MBR, and it was found that a minimum HRT of 4.3 days and maximum ammonia loading of 0.6 kg N- NH4+ m3.d with pH 7–8.5, temperature 25–30 °C, and DO at 2 mg/L is favorable to AOB. Kinetic study was conducted to identify the characteristic of the microorganisms in the system. Measured Ks and μA,max of MBR sludge was 19.65 mg NH4-N/L (Temperature 25 °C, pH 8.5) and 0.26 d−1, respectively.

Janeiro State

The reverse osmosis (RO) process has been increasingly applied to landfill leachate treatment. The published literature reports several studies that investigated the technical feasibility of RO. However, information about process costs is scarce. Also, companies that run leachate treatment plants do not provide actual costs. To fill this gap, this study aimed to evaluate the treatment costs of a full-scale RO for the treatment of landfill leachate located in Rio de Janeiro State, Brazil. A procedure was proposed to estimate the capital expenses (CAPEX), operational expenses (OPEX), and specific total treatment cost, the total cost per m3 of treated leachate, of the leachate treatment by membrane process, and the results obtained are discussed. The CAPEX for this full-scale RO was estimated at MUS$ 1.413, and OPEX ranged from US$ 0.132 to US$ 0.265 m−3 per year. The cost of leachate treatment has been estimated at US$ 8.58 m−3 considering the operation of the RO-unit for 20 years after landfill closure.

Mature Landfill Leachate

In order to verify the feasibility of Fe/C microelectrolysis-Fenton oxidation for mature landfill leachate treatment in industrial application, this study conducted the treatment processes at full-scale by physicochemical and spectral characterization. The full-scale studies showed that 48.17% of the dissolved organic carbon (DOC) and 42.27% of the dissolved organic nitrogen (DON) were removed by the microelectrolysis-Fenton oxidation process, respectively. Spectra analysis further suggested that the mature leachate was mainly composed of tryptophan-like and fulvic-like compounds. The combination of microelectrolysis and Fenton oxidation efficiently decomposed the aromatic C=C into carboxyl-C and decreased the molecular size of DOC, resulting in a dramatic reduce (97.1%-98.3%) of the fluorescence intensity. The DON removal by microelectrolysis-Fenton oxidation likely associated with the NH2-decomposition of tryptophan-like and aromatic compounds into NO3-N. The tryptophan-like compounds may play a dominant role in Ba binding, while Pb and Cd were likely bound to both the tryptophan-like and fulvic-like compounds. Above 60% of the heavy metals were removed in the microelectrolysis-Fenton oxidation section. Results above confirmed the effectiveness of Fe/C microelectrolysis-Fenton oxidation for mature landfill leachate treatment in industrial application.
