Description
Technical field
The invention belongs to field of environment engineering, be specifically related to the testing and measuring technology of the enzyme-added catalytic treatment percolate of a kind of syllogic.
Background technology
Percolate is be mainly derived from precipitation and rubbish itself interior moisture.Owing to liquid has many factors to have influence on the character of percolate in flow process, including physical factor, chemical factor and biological factor etc., so the character of percolate changes in a sizable scope.Percolate is the difficult stain disease of high concentration high pollution of a kind of complicated component, is the rich and influential family of environmental pollution.
Landfill leachate treatment, from the eighties of last century initial stage nineties at the end of the eighties, processes technique and mainly adopts external technology and the processing method with reference to municipal sewage, and the main process technique adopted is generally ammonia aeration+anaerobic treatment+aerobic treatment process.The processing method in this stage is still with biochemistry for core, and it processes target and is mostly the requirement entering municipal sewage plant.Along with the increase of the development in city and pollutant, the concentration of percolate is more and more higher, composition becomes increasingly complex, biodegradability reduces, and amplitude of variation is big, Changing Pattern is complicated so that intractability is increasing.
After 2000, percolate processes the raising required, percolate only cannot meet requirement by materialization+biological treatment, therefore processes technique and occurs in that the method taking comprehensive pretreatment+biological treatment+advanced treating.
After 2010, garbage leachate treatment process percolate adopts the group technology of " pretreatment--biological treatment advanced treating and post processing " in a large number.It is integrated as main process technique frequently with " comprehensive pretreatment+MBR system (AO+ ultrafiltration)+nanofiltration+reverse osmosis ".
The above-mentioned main two kinds of prevailing technology being designed with at present, it is long that its biochemical debugging and operation all also exist debugging cycle, the common problems such as anti-load-bearing capacity is low, and treatment effeciency is poor, and system is unstable.
The complicated components of percolate, pollutant levels are high, colourity is big, strong toxicity, BOD5Several ten thousand mg/L are reached as high as with COD concentration, do not contain only a large amount of organic pollution, possibly together with all kinds of heavy metal contaminants, especially contain non-chlorinated aromatic compounds such as being difficult to biodegradable naphthalene, phenanthrene, chlorinated aromatic group compound, phosphate ester, phthalic acid ester, phenolic compound and amino benzenes compounds etc..Ammonia-nitrogen content is high simultaneously, may be up to about 3000mg/L, when ammonia nitrogen concentration is too high, the activity of microorganism can be affected, reduce the effect of biological treatment, C/N is out of proportion, and P elements lacks, and intractability is big, owing to leakage water containing more hardly degraded organic substance, after existing technique is typically in biochemical treatment, COD concentration is still within the scope of 500～2000mg/L, and biochemical efficiency is low is subject matter.Percolate is high concentrated organic wastewater, containing the high concentration macromolecule organic of the organic amine of various forms and a large amount of uncertain property in water, adopting Traditional materialized, biochemical process to be difficult to reach sewage disposal emission request, in percolate, ammonia nitrogen concentration is high, higher particularly in landfill its concentration of later stage.Although traditional treatment method is a lot, it is respectively arranged with pluses and minuses, but effluent quality all can not be made to reach discharging standards in practice, it has been found that be used alone any process percolate.There is many difficult points in existing technique, especially that the removal effect of total nitrogen is undesirable, increases intractability.Percolate processes costly and is difficult to reach discharge standard.Anaerobism one aerobic biological treatment process is adopted also to be difficult to reach discharge standard；And the investment of high-level percolate treatment plant is big, the problems such as operational and administrative expenses is high, also cannot be properly functioning after causing facility to build up.One of its essential problem is that biochemical workshop section efficiency is low, and the biological metabolism cycle is long, and debugging difficulty is big, it is difficult to meet the requirement that successive depths processes.
The concrete difficult point of percolate biochemistry debugging is mainly percolate and belongs to high concentration hard-degraded organic waste water, and its complicated component, COD value are high, containing multiple pollutant, heavy metal ion and hardly degraded organic substance.Containing multiple poisonous and hazardous inorganic matter and Organic substance, COD, BOD, ammonia nitrogen concentration are high, and colourity is big；Variation water quality is big, and water quality is widely different, is continually changing with the transition in season and the increase of the landfill time limit；Biodegradability constantly reduces with the increase filling age.Containing poisonous and harmful substances such as a large amount of cycloalkane, esters, carboxylic acids and phenol.The process of the percolate restriction owing to being processed cost or treatment effect, various methods have been affected by certain restriction in popularization and application.If absorption method is the transfer of pollutant, removal pollutant of can not fundamentally degrading.Chemical coagulation and the sedimentation method consume substantial amounts of medicament, and produce substantial amounts of poisonous precipitation；Catalytic oxidation investment and operating cost are all comparatively high；Membrane processing method except investment and operating cost all comparatively high except, be easily generated fouling membrane, and blocking, cause membrane lifetime to shorten.Up to the present, some processing methods come into operation are but without the purpose reaching efficient, economic organics removal.Therefore improve the biochemical treatment efficiency of percolate, the biochemical debugging process of quickening becomes a problem in the urgent need to address.
Owing to biochemical system debugging difficulty is big, the problem of debugging cycle length, cause the Complexity and Suitability of technology application in two kinds of common at present prevailing technology cannot form Standardization System, in Practical Project is promoted and applied, all run into biochemical efficiency lowly cannot meet a difficult problem for technological requirement.Therefore, how to improve percolate biochemistry debugging effect, improve biochemical workshop section treatment effeciency, be the difficult point of landfill leachate treatment, be also current problem demanding prompt solution.Research at present is compared many high-effective microorganism bacterium that concentrates on and is strengthened biochemistry debugging with report.It is fewer that associated biomolecule enzyme catalysis solves biochemical testing and measuring technology research.
