Now, with the instrial and agricultural development and improvement of living standards, urban waste have increased. In order to eliminate the adverse impact of waste on the environment, the current use of incineration, composting and landfill and other waste processing methods. Landfill because of mature technology, low cost processing, management and transport convenience, is widely used. However, landfill waste generated in the filtrate water quality very poor, on the water can have serious pollution. Water quality deterioration, water damage will affect the water Water safety and health, and ultimately affect the social and economic sustainable development and human survival. Cost-effective treatment of landfill leachate into the landfill waste disposal problems to be solved at work.
Through the combination of two different processes "SBR + coagulation + Fenton oxidation + BAF" and "SBR + MF + RO" water for the treatment of landfill leachate study at all levels investigated COD (chemical oxygen demand), ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, dissolved organic matter (DOMs), total P, sulfate and other processing in each process change. The results show that, "SBR + coagulation + Fenton oxidation + BAF" process on COD and NH3-N removal rates were 98.4%, 99.3%, on the DOMs removal rate was 98.3%, while the leachate of SS, color degree, has also been very good to remove the smell. The combined technology in leachate treatment have better results.
Key words: landfill leachate, DOMs, 3N, SBR + coagulation + Fenton oxidation + BAF.
