Description
Technical field
The utility model relates to a kind for the treatment of system of field of environment protection percolate, particularly the oxidized coagulated treatment system of a kind of concentrated solution of percolate.
Background technology
Present stage, in garbage leachate treatment process, the main flow treatment process is microbiological treatment+membrane filtration both at home and abroad.The concentrated solution that produces in the membrane filtration processes has following characteristics: 1, concentrated solution output is large; Be 30～40% of film flooding quantity in half a year with the output of interior new membrane concentration liquid duration of service, and half a year, above membrane concentration output of fluid was about 50% of film flooding quantity, and along with film increases duration of service, this amount also can increase; 2, COD is higher, and the COD main component in the concentrated solution is the organism of difficult degradation, and generally with the difference of region and local resident's food habits, the COD of concentrated solution is between 1000～3000mg/l; 3, colourity is high; The colourity of concentrated solution is generally more than 500 times, and NH3-N concentration is higher, and colourity is higher; 4, biodegradability is poor: the organism in the concentrated solution mainly is the difficult degradation composition, and being difficult to provides nutrition source to microorganism; 5, stronger stink is arranged.
At present, both at home and abroad in garbage leachate treatment process, the processing of concentrated solution or terms of settlement roughly have two kinds: the one, concentrated solution directly is back to leachate equalization basin, or concentrated solution collected, then through oxidation ditch or other way concentrated solution is carried out recharging leachate equalization basin after simple process reaches homogenizing effect.The essence of this treating method is exactly the process of concentrated solution infinite reflux.
The drawback that infinite reflux brings is apparent, accumulation along with the time, the amount that is back to the hardly degraded organic substance accumulation of equalizing tank gets more and more, and this hardly degraded organic substance can not provide nutrition source to microorganism, cause the biodegradability of percolate worse and worse, the function of whole biological treatment system reduces gradually in the percolate treating process thereby make, until go functionalization.The 2nd, evaporation concentration or charcoal absorption are processed, the cost of this method is high, the usually conduct cost is at 200～300 yuan/tons, if employing evaporation process, whole vapo(u)rization system has to consider the problem of high-temp anti-corrosion, and along with the growth of duration of service, because the fouling of equipment causes heat transfer efficiency to descend seriously, processing cost further increases; The difficult problem of the maximum that the activated carbon treatment concentrated solution faces is the regeneration of gac, so that cost is high.
In addition, the treatment process that also has a kind of laboratory report: the processing means take ion exchange resin as core of the Li Aimin of Nanjing University professor and the joint study of German Wei Erli company it is reported that discharge water after the processing meets the first discharge standard among the GB16889-97.This method is that adsorb organic compound take the antipollution resin is as main processing means; from existing pollution-resistant ion exchange resin; can the long period under the condition of hardly degraded organic substance concentration, use and not contaminated resin not discovery at home and abroad reported; general common domestic and international ion exchange resin (no matter macroporous type or gel-type) uses under high COD condition; operating capacity can sharply descend; protective layer is easy to be penetrated by COD; simultaneously; the regeneration waste liquid of concentrated solution by ion exchange resin absorption after resin absorption is saturated (usually regeneration waste liquid be treatment capacity about 10%) processing be a more thorny difficult problem; so it is to be tested that the reliability of this method has, be appreciated that the minimizing to concentrated solution is good.
In garbage leachate treatment process, the main flow treatment process is microbiological treatment+membrane filtration both at home and abroad at present.The concentrated solution that produces in the membrane filtration processes has following characteristics: 1. concentrated solution output is large; Be 30～40% of film flooding quantity in half a year with interior new membrane concentration output of fluid duration of service, and half a year, above membrane concentration output of fluid was about 50% of film flooding quantity, and along with film increases duration of service, this amount also can increase.2.COD higher, and the COD main component in the concentrated solution is the organism of difficult degradation; Generally with the difference of region and local resident's food habits, the COD of concentrated solution is between 1000～3000mg/l.3. colourity is high; The colourity of concentrated solution is generally more than 500 times, and NH3-N concentration is higher, and colourity is higher.4. biodegradability is poor: the organism in the concentrated solution mainly is the difficult degradation composition, and being difficult to provides nutrition source to microorganism; 5. stronger stink is arranged.
For film filtration concentrated middle organic components in the present percolate main flow treatment process and its principal feature, adopt the method for catalyzed oxidation+secondary oxidation+coagulating sedimentation+filtration+sludge dewatering recycle-water, the indices such as colourity, COD, NH3-N, SS, BOD5 and bacterium value of concentrated solution are controlled in the desired primary standard scope of GB16889-97.
Present stage, the concentrated solution treatment process mainly contained:
(1) recirculation process, its main drawback is that the salt that produces in concentrated can circulate in waste containment system always, in the percolate salt accumulation serious, specific conductivity rises very fast, greatly reduce the producing water ratio of subsequent film system, affect the steady running of percolate treating process;
(2) evaporation treatment process, the evaporation process of concentrated solution has solved the drawback that the concentrated solution infinite reflux brings.The full retrieving arrangement of the evaporation process technology utilization efficient automatically control evaporation energy is processed oozing drop liquid.The evaporation technology Main Problems is the etching problem that expense is high and the vaporizer generation is serious at present; The expense of Theoretical Calculation evaporation process is at 150 yuan/tons, reality is higher than this value far away, according to the present practical operation situation of the leachate treatment factory of domestic several use concentrated solution evaporation treatment process, general cost is at 200-800 yuan/ton, and acid corrosion and the brine corrosion in the liquid phase that vaporizer suffers are quite serious, cause facility investment and maintenance cost large, equipment failure rate is also comparatively frequent during operation, and facility can't be stablized continued running.
(3) ion-exchange or charcoal absorption treatment process, according to ooze organism colloid in the drop concentrated liquor electrically, select anionite-exchange resin to transfer to most organism on the ion exchange resin, different according to organic size of particles, at resin surface two kinds of different processes have occured: the absorption of exchange and similar molecular sieve.Select ion exchange resin exchange organism with selecting ion exchange resin at high-enriched organics kind exchange inorganic salt different in kind, it is very obvious that the former operating capacity can reduce trend gradually along with the increase for the treatment of capacity, and the latter is much smaller.After charcoal absorption is saturated, must just can recycle by regeneration, and the regeneration cost of gac is very high, has finally caused the rising of leachate treatment cost.Ion exchange resin can play inrichment to the organism in the concentrated solution, but how the organism in the regeneration waste liquid is processed and concentrated solution in heavy metal to process be again the ion exchange process urgent need to solve the problem.
(4) concentrated solution returns the spray burning process, and owing to now domestic a lot of landfill yards and waste incineration facility are neighbour building, concentrated solution returns the spray incineration technology and also begins developed.This technique is sprayed onto the burning of incineration plant incinerator opening for feed with the concentrated solution that reverse osmosis produces through returning behind the pretreatment technology.It is simple to return the operation of spray burning process, and front-end investment is also less, and time spray treatment process of concentrated solution is based on the burning disposal principle of garbage leachate.Western developed country since in the rubbish kitchen excess few, calorific value is high, it is few to ooze the drop output of fluid, general employing will be oozed drop liquid and be returned the spray incinerator and carry out high temperature oxidation process.Returning the spray method, to be suitable for concentrated solution output few, the occasion that refuse thermal value is high, and the rubbish lower for calorific value then is not suitable for, otherwise can cause the incinerator fire box temperature excessively low, even flame-out situation.In European Region and Japan, because Waste sorting recycle work is well-done, the waste water ratio of delivering to incineration plant as rubbish is low, and refuse thermal value is very high, so in the rubbish power station of having moved, all be to adopt to ooze the method that drop liquid directly returns spray.Having data to claim is 1223kcal/kg through calculating for calorific value, and water ratio is 48% domestic waste, and oozing in theory the maximum time discharge rate of drop liquid is 3.19% of waste incineration amount.If the larger situation of concentrated solution generation is normally to adopt this technique to process.And the acid corrosion that can suffer equally of the same incinerator with the concentrated solution evaporation treatment process and the corrosion of the salt in the liquid phase, equipment failure rate is also comparatively frequent during operation, and facility can't be stablized continued running.
(5) Advanced Oxidation Technics in Dealing, for some biodegradable poor ooze drop liquid, biological treatment often is difficult to carry out.Adopt physicochemical techniques to process that then running cost is too high, and produce the resistates that is difficult to process sometimes.At present, high-level oxidation technology (AOP), as: ozone, H2O2/UV, Cl2/UV etc. are difficult to biological degradation or to the processing of the material of biological poisonous and harmful effect, have demonstrated the advantage of its uniqueness for those.AOP produces hydroxyl radical free radical (.OH) by chemical oxidation, and the alkyl in the oxidation garbage leachate, ketone, aldehyde functional group make that aromatic nucleus splits, two key addition and mineralising etc.Mainly contain following several: 1. 2. 3. 4. 5. gac-H2O2 catalytic oxidation of electron radiation facture of photocatalytic oxidation of Fenton reagent oxidation method of ozonation technology.
Advantages such as Fenton reagent has and is swift in response, and the conditions such as temperature, pressure relax and non-secondary pollution, and are cheap and extensively being used.Cheng Jiehong, the slip-stick artists such as Li Eryang once used the Fenton Coagulation Method that the drop liquid that oozes of Chongqing City's refuse landfill is carried out pre-treatment, the COD clearance reaches 66.9%, can make former water COD be down to 8518mg/L from 25733mg/L, for follow-up anaerobic-aerobic biochemical treatment provides preparation.Operational conditions is: pH=3.0; FeSO4.7H2O=0.4%; H2O2=4.3ml/L; Reaction times is 1h.When being used for the concentrated solution processing, because the molecular structure of concentrated solution is more stable, selecting of advanced oxidation reagent is then more harsh.Although high-level oxidation technology has represented good treatment effect, owing to the reason of various actually operatings also rests on laboratory stage at present.
(6) biochemistry+chemical association treatment process, the many combined treatment process that adopt at present are biochemistry-oxidation-coagulation-settlement processes.Its principle is to be adapted under the high TDS existence at bacterial classification by cultivation, guarantee biochemical treatment by traditional A/O+MBR technique to the concentrated solution biological denitrificaion.Then add oxygenant and the catalyzer (hydrogen peroxide and molysite) of selecting in the oxidation section, by the 1# radical reaction mechanism COD and TN are removed, strong oxidation panel COD clearance is that 75%, TN clearance is 90%.Remove by the SS of coagulation-settlement process to water outlet at last.Concentrated solution with certain landfill yard reverse osmosis of south is treated to example.At present southern certain household refuse landfill sites reverse osmosis concentrated liquid COD:3600-4000mg/L, B/C＜0.1, TDS:24000-30000mg/L are by water outlet COD≤60mg/L, TN≤20mg/L after biochemistry+chemical association art breading.
Biochemistry+chemical association treatment process can be broken down into carbonic acid gas to most organism, and various form nitrogen are processed to the nitrogen form, many drawbacks of having avoided the backflow of concentrated solution to bring.The salt of high valence state and heavy metal also can obtain being completely fixed by the advanced oxidation processes section, have solved the problem of whole system salt balance.In the concentrated solution treatment process, only have two portions to have water loss in the system: total nitrogen is removed system and the discharging of little flocculation process, and the water rate of recovery is more than 90% in the total nitrogen removal system.The precipitation process of coagulation water rate of recovery is more than 95%.The water rate of recovery of whole system is more than 92.5%.Use biochemistry+chemical association technique can guarantee the higher system water rate of recovery.Because the technology chain of biochemistry+chemical association technique is comparatively perfect, the anti-load impact ability of whole technique is stronger.
But the difficult point of this technique is biochemical section for the cultivation of bacterial classification and selects, and common micro-organisms is to be difficult to existence in the situation of high salinity, and it is more rambunctious keeping certain sludge concentration to carry out nitrated-denitrification process.Secondly also very crucial for the selection of oxygenant in the deep oxidation section, hydrogen peroxide and clorox etc. usually oxygenant are to play the deep oxidation effect.Biochemistry+chemical association treatment process is in the pilot scale stage, about 45 yuan/tons of processing cost at present.
It is the difficult problem of a professional that the concentrated solution qualified discharge that membrane filtration produced during percolate was processed is processed, reach or be better than first discharge standard among the GB16889-97 and directly discharging if can concentrated solution be processed with lower cost, the benefit of then bringing is the water production rate of whole percolate treating process can be increased about 40%, can solve again because the problem of the whole biological treatment system function degradation that the concentrated solution infinite reflux causes.
