Description
[technical field]
The present invention relates to a kind of in, the treatment process for the treatment of of advanced stage landfill leachate.
[background technology]
Percolate is the sewage oozing out from refuse landfill, because it has dissolved the many materials in component of refuse, thereby make the composition complex of percolate, principal pollutant comprise that large amount of organic is as organic hydrocarbons and their derivates, sour lipid, heavy metal, nitrogen salt etc., its key character is: COD is low at several thousand milligrams per liter, ammonia nitrogen total nitrogen is high more than 1000 milligrams per liter, and colourity is dark.If without harmless treatment, by severe contamination soil and water system around.Up to now, the method for the domestic relatively ripe treating refuse percolate with studying mainly contains biological treatment and chemical method, and biochemical process comprises anaerobism, aerobic treatment, AB method (being adsorption-flocculation, bio-oxidation double diffusion), bio-oxidation pond etc.Chemical method mainly contains Ozonation, hydrogen peroxide oxidation process, active carbon adsorption etc.The method that developed countries adopts is more, and what more generally use is materialization and the biochemical technique combining, and due to by the more difficult emission request that reaches of biochemical process, generally after biochemical treatment, all will adopt membrane filtration process.Some adopts distillation and concentration method, the processing of osmosis filtration method, and these two kinds of methods are due to construction investment and working cost is high and the dense water that produces recharges refuse tip and pollute thing accumulation.At present the disposal site percolate of domestic many large-and-medium size cities all exist treatment effect poor, also need to enter again the problems such as municipal sewage plant processes after processing, therefore efficiency is lower, cost is higher.
