| Municipal landfill leachate is a serious treatment question as a complicated waste water of high ammonia and refractory organics. At present, The common processes are biological treatment process and Physical-chemical process. The biological process includes aerobic, anaerobic process and combination of both processes. The biological process is effective for the ammonia-nitrogen (NH4-N) and easy-biodegraded leachate. Furthermore biological process can't lead to second pollution and has low cost. The pHysical-chemical process includes coagulation, deposition, adsorption, membrane, advance oxidation and so on. The Physical-chemical process is not affected by the leachate quality and production. It is effective for the non-biodegraded leachate. The advance oxidation can degrade hart-treated substance more efficiency.Organics and ammonia are the main removal pollutants which decide the construction and operation cost. For their removal, the thesis uses home and abroad research result for reference, take that the technology developing out is feasible, economy high-effect rubbish infiltration liquid handles a handicraft as target, adopt Fenton- coagulation- adsorption column allies handicraft carries out treatment on infiltration liquid studying. The aeration adsorption post having inspected Fenton- coagulation - adsorption column allies the handicraft removal effect of COD and ammonia nitrogen, inspecting at the same time also coal cinder's feasibility making reuse. The experiment study on the factors of treatment affect which include initial pH,the concentration of H2O2,the concentration of Fe2+,reaction time,the concentration of polymerization iron,water-entering flow rate, reaches the best reaction condition. The effect of Fenton- coagulation- adsorption column is better. The removal efficiency of COD reaches 80.5%, the removal efficiency of ammonia-nitrogen also reaches 72.15%, and operating it costs low. It is economic feasibility.
