COD removal from landfill leachate using H2O2, UV radiation and combination these processes

Pieczykolan B., Barbusiński K., Płonka I.

Vol. 38, nr 3

Experiments for removal of organic compounds (expressed as COD) from "young" municipal landfill leachate, using oxidation by H 2O2, UV photooxidation and UV/H 2O2 process, were carried out on a laboratory scale. Studies have shown that the most effective method was UV/H 2O2 process. When oxidation was conducted under the most suitable conditions (parameters found during experiments), maximum value of COD removal equaled 74.6%, 19.6% and 19.3% when the treatment was realized by use of H 2O2/UV, H 2O2 and UV radiation, respectively. These results demonstrate that in order to attain high efficiency of COD removal, use of advanced oxidation process (H 2O2/UV) is necessary.

Short-term aerobic in SITU stabilization of municipal landfills: Laboratory tests

Ślęzak R., Krzystek L., Ledakowicz S.

Environment Protection Engineering

2009

Vol. 35, nr 3

81-92

The simulation of the in situ aerobic stabilization of waste was carried out in laboratory scale Iysimeters for a short period of time. In leachates, BOD5, COD, VFA, N-NH4, TKN and pH were assayed and in outlet gas the concentrations of methane, oxygen and carbon dioxide were determined. Whilst aerating waste, one could observe a decrease of organic load in leachates and lack of methane emission. After finished short-term aeration an increase in leachates indices occurred and methane in outlet gas from lysimeter appeared. In subsequent days after finished aeration one could observe a decrease in the indices of leachates and further production of methane.
