Abstract Treatment of leachate from an exploited since 2004 landfill by using two methods of advanced oxidation processes was performed. Fenton’s reagent with two different doses of hydrogen peroxide and iron and UV/H2O2 process was applied. The removal efficiency of biochemically oxidizable organic compounds (BOD5), chemically oxidizable compounds using potassium dichromate (CODCr) and nutrient (nitrogen and phosphorus) was examined. Studies have shown that the greatest degree of organic compounds removal expressed as a BOD5 index and CODCr index were obtained when Fenton’s reagent with greater dose of hydrogen peroxide was used - efficiency was respectively 72.0% and 69.8%. Moreover, in this case there was observed an increase in the value of ratio of BOD5/CODCr in treated leachate in comparison with raw leachate. Application of Fenton’s reagent for leachate treatment also allowed for more effective removal of nutrients in comparison with the UV/H2O2 process.

In this study, the application of ozonation and ozonation with hydrogen peroxide processes for landfill leachate treatment was investigated. The effluents were characterized by COD 710 mgO2/dm3 and BOD5 72 mg O2/dm3. According to the adopted indicators, the determined BOD/COD ratio of 0.1 in raw leachates indicates a stabilized landfill. Ozone was applied at doses of 0.15 - 0.6 gO3/dm3, and hydrogen peroxide at such doses to keep the weight ratios of H2O2/O3 0.4 - 1.6. The maximum COD and UV absorbance removal was respectively 29% and 51% by applying a high ozone dose of 0.6 gO3/dm3. After oxidation, the ratio of BOD/COD was increased from 0.1 up to 0.3. It has been shown that by using hydrogen peroxide in ozonation, organic compounds expressed as COD can be efficiently removed from the effluents. The best conditions for the H2O2/O3 process were obtained with a H2O2/O3 ratio of 0.8 and ozone dose of 0.6 gO3/dm3. Under these conditions, the removal efficiency of COD was 46%.

Sanitary landfilling is the most acceptable method to eliminate solid urban wastes. However, it is known that sanitary landfill generates large amount of heavily polluted leachate. High concentrations of recalcitrant organics make its degradation more complicated and high concentration of organic material can be toxic and reduce bioremediation process. Landfill leachate treatment by advanced oxidation processes (AOPs) have been intensively studied with high successful rate for removing refractory pollutants (biological degradation) from leachate. Fenton reaction which is one basic AOPs is based on the addition of hydrogen peroxide to the leachate in the presence of ferrous salt as a catalyst. Because of that, many improvement and development of new Fenton-based methods have been reported in the literature. This review discussed the application of Fenton and related processes in terms of wide application in landfill leachate treatment. The effects of various operating parameters and their optimum ranges for organics contaminant removed were also discussed.

Waste Leachate

Leachate is a high concentration organic wastewater, and microbial fuel cell (MFC) is capable of decomposing and treating organic pollutants directly. Single-chamber MFC using landfill leachate as anolyte was built to get rid of BOD and ammonia-nitrogen organic pollutant in leachate. The use of MFC led to the treatment of the biodegradable organic pollutant of municipal solid waste leachate and the production of electricity. The biofilm was detected on the MFC anode carbon felt, the voltage and power output were achieved 292.7± 5 mV and 2375.1mW.m-2. The suitable running time was about 10 days, when the BOD and ammonia-nitrogen removal efficiencies were achieved about 93.0% and 84.1 %, respectively.
