Background technique
With the rapid development of economy and increasing substantially for people's living standard, municipal refuse yield is in rise year by year
Trend.China is to the processing mode of municipal refuse mostly based on sanitary landfills and compost at present.The landfill leachate of generation at
Divide complexity, pollutant concentration is high, coloration is big, strong toxicity, not only contains a large amount of organic pollutants, also contains all kinds of heavy metal pollutions
Object.The processing problem of resulting landfill leachate becomes one of the important topic of the world today.
The processing of percolated liquid in city refuse landfill is always very intractable in Landfill Site Design, operation and management asks
Topic.Percolate is product of the liquid in landfill yard gravity flowing, is mainly derived from the interior aqueous of precipitation and rubbish itself.Due to liquid
Body may influence the property of percolate, including physical factor, chemical factor and biology in many of flow process factor
Factor etc., so the property of percolate changes in a sizable range.In general, pH value is between 4~9, COD
In the range of 2000~62000mg/L, BOD5 heavy metal from 60~45000mg/L, heavy metal concentration and municipal wastewater
Concentration is almost the same.Percolated liquid in city refuse landfill is a kind of high concentrated organic wastewater of complicated component, if untreated
It is directly discharged into environment, will cause serious environmental pollution.For the purpose of protecting environment, it is essential for carrying out processing to percolate
's.Landfill leachate is a kind of high concentration organic garbage filter liquid for being difficult to be handled, mainly from following three aspects:
1, the natural precipitation and runoff in landfill yard；2, the water that rubbish itself contains；3, due to the anaerobism of microorganism after garbage loading embeading
The water for decomposing and generating；Wherein the precipitation in landfill yard is major part.The water quality of landfill leachate has following essential characteristic:

It is difficult to the non-chlorinated such as biodegradable naphthalene, phenanthrene aromatic compound, chlorinated aromatic race compound, phosphate, phthalic acid ester, phenol
Class compound and amino benzenes compounds etc..
(4) contain 10 various metals ions in landfill leachate, heavy metal ion therein can produce biological treatment process
Raw serious inhibiting effect.
(5) microbial nutrition element ratio numerous imbalances in percolate.Ammonia nitrogen concentration therein is very high, and C/N ratio is lost
It adjusts, nutritive proportion required for microorganism grows when nutritive proportion is than Biochemical method greatly differs from each other, and brings to biological treatment
Certain difficulty.
The ammonia-nitrogen content and COD concentration of landfill leachate are high, make surface water body anoxic, water quality deterioration；The nutrients such as nitrogen phosphorus
Matter is to lead to the inducement of water eutrophication, it is also possible to seriously affect drinking water source；In general, COD, BOD, BOD/COD
It can increase with " age " of landfill yard and reduce, level of alkalinity then increases.In addition, with the increase for stacking the time limit, new refuse
Aging rubbish is gradually become, Organic Pollutants of Landfill Leachate content is declined, but ammonia-nitrogen content increases, and biodegradability reduces, because
This processing difficulty is very big.
