Description
Technical field
The utility model relates to field of environment engineering, relates in particular to a kind of small-sized rubbish percolate Simple treatment device.
Background technology
The main rubbish that the residential district produces is domestic refuse, and such as rubbish from cooking, discarded clothes packing, old and useless battery etc., integral part mainly contains large amount of organic, inorganic wastes and poisonous and harmful resistates.Settlement dumping point and garbage transfer station are cleared the rubbish that comes with each bleeding point and are concentrated the stacking compression nearby, save the space, continue to transport to refuse landfill far away again.Be attached to rubbish leaching stream drop out, organic matter in garbage matter decomposes and produces and stack the waste water that the compressed garbage process squeezes out and jointly consist of percolate.Because domestic rubbish does not pass through strict classification and screening as Cities of Foreign Countries, so the percolate heavy metal content is high, generally contain 10 many kinds of metal ions, wherein concentration of iron can be up to 2050mg/l, plumbous concentration can reach 12.3mg/l, zinc concentration can reach 130mg/l, and the concentration of calcium can reach 130mg/l.Except metal ion content greatly, the percolate ammonia-nitrogen content is also higher.Ammonia nitrogen in high density is one of important water quality characteristic of city garbage percolate, in the situation that without pre-treatment with regard to landfill waste, along with landfill year number increase and increase, can be up to 1700mg/l, nitrogen in the percolate exists mainly with the ammonia nitrogen form, accounts for 70% ~ 80% of TN.In addition, COD in the percolate, BOD concentration are high, contain a large amount of organic matters, cause C/N excessively low, can not satisfy the nutritive element ratio demand of microorganism BOD:N:P=100:5:1, thereby with the passing of time back and forth also be difficult to be fallen by natural biochemical action regulate metabolism.
Percolate contains considerable toxic substance, if the not treated rivers and lakes that directly enter, organic pollutant wherein, inorganic pollutant can make hydrobiont and farm crop be polluted, and by food chain and ecotope HUMAN HEALTH is produced harm.Present garbage transfer station is all seldom taked treatment measures to percolate, substantially be directly to be discharged to the rain sewage network, also occurred percolate when more having very and put the phenomenon that flows on the road surface from stacking, consequent foul smell, the mosquitos and flies that grows have been caused very large puzzlement to resident living.
In sum, must effectively process percolate, be down to its impact on environment minimum.But dumping point and transhipment station in the Residential areas, the day long-pending total amount of this percolate is very little again, if only go up environmental impact assessment requirement sewage treatment facility up to standard for a garbage transfer station, then cost is too high, processing efficiency is too low.
Thereby invent a kind of applied widely, treatment effect good, technology and equipment with low cost and that take up an area the simple and easy improvement percolate of little, convenient operating maintenance becomes the task of top priority.
Summary of the invention
Have the defective that cost is high, processing efficiency is low for existing device for treating leachate, the utility model provide a kind of applied widely, treatment effect good, with low cost and take up an area small-sized rubbish percolate Simple treatment device little, convenient operating maintenance.
