The study also indicated that the reaction in the reactor could be described by the equation dC/dt=-akC,and the method could be used as the pretreatment progress of landfill leachate.
Landfill leachate is very difficult to treat with characteristics of high concentration of organic substance,NH3-N and multi-composition of pollutants.
Landfill leachate was treated by UV/Fe3+/H2O2 oxidation-coagulation process. The effects of initial pH on wastewater, dosage of H2O2 and Fe3+ , reaction time, reaction temperature, pH and mass concentration of the coagulation agent were investigated.
The optimal COD removal condition for 20mL landfill leachate with 896mg/L COD were testified following pH value below 3, 6mL FeSO4 at 6mmol/L, 1mL H2O2,microwave irradiation 800Wfor 4min, and the COD concentration was below 200mg/L for post-treated landfill leachate。

The nitrogen removal mechanism was studied and analyzed when treating the ammonium-rich landfill leachate by a set of sequencing batch biofilm reactors (SBBRs), which was designed independently.
Reverse osmosis system with the disc-tube module (DT-RO) was applied to treat landfill leachate on full scale at the Changshengqiao Sanitary Landfill, Chongqing City, China.
A laboratory-scale sequencing batch reactor (SBR) is used to treat landfill leachate containing high concentration of ammonium nitrogen with municipal fecal supernatant.

Between March 1994 and April 1997, the physical and chemical parameters and chemical composition of the urban solid waste leachate of the Marbella landfill (southern Spain) were determined.
The effect of pH on the Cd distribution coefficients was less consistent in waste leachate than in unpolluted soil solution, varying from hardly any effect to a 7 fold increase for a pH increase of approximately one unit.
