Description
Technical field
The utility model relates to garbage filter concentrated solution process field, relates in particular to a kind of garbage filter concentrated solution treatment system and method.
Background technology
Whether the qualified discharge of percolate is measurement landfill yard is one of important indicator of sanitary filling field.Percolate is the product that liquid flows at landfill yard gravity, is mainly derived from the interior moisture of precipitation and rubbish itself.Because liquid has many factors may have influence on the character of percolate in flow process, comprise physical factor, chemical factor and biotic factor etc., so the character of percolate changes in a sizable scope.Therefore, percolate intractability is high, even if adopt anaerobism to aerobic biological treatment process to be also difficult to reach emission standard; In addition, because percolate water quality and general sewage have larger difference, very unstable.Generally, simple biologic treating technique is difficult to meet requirement up to standard, and builds special percolate treatment plant investment greatly, and operational and administrative expenses is high, and order is along with the closedown of landfill yard, finally makes water processing establishment scrap.Therefore, the process of percolated liquid in city refuse landfill is unusual stubborn problem in Landfill Site Design, operation and management always.
In addition, the treatment stage that the domestic research to garbage leachate treatment process resting on garbage loading embeading factory percolate mostly.And garbage burning factory percolate and garbage loading embeading factory percolate feature difference to some extent: in incineration plant percolate, the mean concns of COD, BOD5 is higher, also poorer compared with the biodegradability of landfill percolate.And incineration plant percolate belongs to primary percolate, the percolate on the same day mostly, without anaerobically fermenting, hydrolysis, acidization, include as hardly degraded organic substances such as heterocyclic arene compound, polycyclic aromatic hydrocarbons, phenol, alcohol compound, amino benzenes compounds such as benzene, naphthalene, phenanthrene.Affect little compared with landfill factory percolate by rainwater.
At present, major part landfill yard all takes the combination process of physico-chemical pretreatment (coagulating sedimentation, ammonia-nitrogen desorption, chemical oxidation etc.)+biological body process+materialization advanced treatment (absorption, reverse osmosis, catalyzed oxidation etc.) such as (anaerobism, anoxic, aerobic), and water outlet enters rivers or the municipal network of rivers.Meanwhile, also multimembrane treatment process in the materializing strategy that incineration plant landfill leachate treatment is last.
Therefore, the technique of biochemical treatment+NF/RO film process is more and more applied in landfill leachate treatment, and a large amount of film-filter concentration liquids becomes problem demanding prompt solution.The current research for film-filter concentration liquid is many also rests on laboratory stage, and the research and development film-filter concentration liquid treatment technology that can be applicable in Practical Project is very necessary and urgent, should cause enough attention.Percolate film-filter concentration liquid be percolate after biological degradation through raffinate that RO film (or NF film) retains, generally not there is biodegradability, major ingredient is Humus material, in brownish black, COD very high (usually between 1000 to 5000mg/L), and containing a large amount of mineral ions, ammonia nitrogen concentration is at 100 to 1000mg/L, and specific conductivity is 40000 to 50000 μ s/cm.The volume of film-filter concentration liquid accounts for 8% to 30% of percolate stoste volume.Because concentrated solution contains the organic of various difficult degradation and inorganic pollutant, directly discharge may produce soil, surface water, ocean etc. and pollute; If enter municipal sewage system, too high total dissolved solid is also unfavorable to the growth of active sludge.In the past, a lot of destructor plant all adopted the measure of recharging to process percolate concentrated solution, but recharged and the biodegradability of percolate can be caused greatly to reduce finally make system scrap.Therefore the research for concentrated solution continuation process is necessary, and the development research of correlation technique is also a focus in leachate treatment technology.
At present, concentrate liquid for percolate, the domestic method of evaporation or advanced oxidation that adopts carries out treatment and disposal more, but treatment process is not mature and stable, can say and still not stablize effective process means.
