Description

A kind of garbage percolation liquid treating system
Technical field
The utility model relates to refuse leachate processing technology fields, more specifically, are related at a kind of refuse leachate Reason system.
Background technique
With the increase of China's urban population, the raising of the expansion of city size and Living consumption, China city is raw The yield of rubbish living is sharply increasing.By 1999, the domestic waste in China up to 1.4 hundred million tons, and with annual 8%~ 10% speed increase, the rubbish that day generates per capita is more than 1kg, close to industrially developed country's level.
Whether landfill leachate handles qualified discharge, be measure landfill yard whether be sanitary filling field important indicator One of.One underproof refuse landfill is exactly a big pollution sources, is such as collected, handles to it not in time, making The pollution and influence of pairs of underground water, surface water and refuse landfill ambient enviroment.Especially it is to underground water source and soil It pollutes even more serious.Percolate permeates the ground in water, causes the serious pollution to underground water.Its pollution perdurabgility can be up to Many decades or even upper a century.Once underground water source and surrounding soil are polluted by it, think to implement to purify again by artificial means, technology On will be extremely difficult, expense is also extremely expensive, it is difficult to implement, to seriously threaten the life and production of people.So to rubbish Rubbish percolate, which carries out processing up to standard, to be very important.
Mainly use the artificial degradation method of purification at present, it utilizes the biodegradability of percolate, by the facility that is manually arranged, Equipment allows percolate to be purified by the methods of anaerobism, aerobic and standing, precipitating, reaches and effectively eliminate percolate dirt Contaminate the purpose of environment.These methods substantially have following several: 1. leachate recirculation method, send percolate back to garbage loading embeading area, lean on Anaerobic degradation again is seeped into rubbish heap in evaporation.It is larger using the difficulty of this method, it is only capable of playing the water for accelerating landfill leachate The stable effect of matter, degree for the treatment of is low, cannot reach the discharge standard of national regulation;2. land treatment systems method, which is to be percolated It developed on the basis of liquid recharge, be the filtering retention using soil-plant system, including soil, physics is heavy with chemistry It forms sediment, absorption, decompose, the intake of plant and microorganism, oxidative degradation, evaporation and transpiration etc. achieve the purpose that purify percolate.But Because the water quality of landfill leachate is complex in composition, variation is big, there may be certain contents of heavy metal elements exceeded in special percolate, and Southern soil belongs to acid more, is conducive to moving and being absorbed for heavy metal, therefore this method is according to improper, it will cause dirty filling The destruction contact scar of soil;3. biological pond method, biological pond processing technique, especially aquatic plant system processing technique are at home There is use, but the method organic loading is not high, occupied area is very big;4. biochemical method, biochemical method is answered in the processing of percolate percolate With extensive.But when being used alone, operational effect is not very stable.It is therefore desirable to improve.
