Description
Technical field
The utility model relates to a kind of pretreatment unit of percolate from garbage filling field membrane concentration liquid evaporation equipment.
Background technology
The Environmental capacity of city garbage percolate is a great problem in municipal wastes Landfill.2008, country promulgated " household refuse landfill sites Environmental capacity standard " (GB16889-2008), has higher requirement to the process of percolate.Along with the raising of standard, the process of percolate more have employed the combination process of biochemistry+membrane filtration.NF, RO film is more and more used in landfill leachate treatment.But while qualified discharge supernatant liquor, inevitably produce film filtration concentrated.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 is very high, and containing a large amount of mineral ions, TDS is between 20000-60000mg/L, COD is usually between 3000-5000mg/L, and ammonia nitrogen concentration is at 100-1000mg/L, and specific conductivity is 40000-50000 μ s/cm.The volume of film-filter concentration liquid accounts for the 25%-50% of percolate stoste volume.
Because concentrated solution contains the organic of various difficult degradation and inorganic pollutant, directly discharge can 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.Concentrated solution is returned in landfill yard again to recharge process by existing a lot of percolate treatment plant, but this also brings a lot of problems, and too high COD and TDS concentration is again repeatedly to obstruction film processing components, and the frequency that film is changed is faster.
Utility model content
The pretreatment unit that technical problem to be solved in the utility model is to provide a kind of percolate from garbage filling field membrane concentration liquid evaporation equipment overcomes existing landfill percolate concentrated solution in prior art and deals with improperly and cause polluting or blocking film processing components, increases the defect of processing cost.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of pretreatment unit of percolate from garbage filling field membrane concentration liquid evaporation equipment, comprise coagulation basin, flocculation basin and settling tank, described coagulation basin is successively by pipeline communication flocculation basin and settling tank, and the liquid outlet of described settling tank is communicated with evaporation equipment; Described coagulation basin is provided with landfill percolate concentrated solution entrance.
The beneficial effects of the utility model are: this equipment is by arranging coagulation basin, flocculation basin and settling tank, effectively can process further landfill percolate concentrated solution, can remove more than 90% calcium, magnesium ion, about 50% silicon-dioxide and most fluorion, simultaneously remove about 20% COD organism.
On the basis of technique scheme, the utility model can also do following improvement.
The pretreatment unit of the utility model a kind of percolate from garbage filling field membrane concentration liquid evaporation equipment described above, further, installs agitator in described flocculation basin.
The pretreatment unit of the utility model a kind of percolate from garbage filling field membrane concentration liquid evaporation equipment described above, further, also comprise intermediate pool, described intermediate pool to be connected between described settling tank with described evaporation equipment and to be communicated with respectively with described evaporation equipment with described settling tank.
The pretreatment unit of the utility model a kind of percolate from garbage filling field membrane concentration liquid evaporation equipment described above, further, described coagulation basin, flocculation basin, be all communicated with mud vent pipe bottom settling tank and intermediate pool
The method that the pretreatment unit of above-mentioned percolate from garbage filling field membrane concentration liquid evaporation equipment processes landfill percolate concentrated solution, comprise the following steps: step 1) landfill percolate concentrated solution is pumped in described coagulation basin, regulate pH, make the pH of landfill percolate concentrated solution adapt to the needs of coagulating agent, after adding coagulating agent, mixing liquid pumps in flocculation basin;
Step 2) in flocculation basin, add flocculation agent and fully stir, after complete reaction, the mixed solution after flocculation is accessed described settling tank and precipitates, after settling tank precipitation, overflow supernatant liquor, supernatant liquor access evaporation equipment.
Accompanying drawing explanation
Fig. 1 is the pretreatment unit structural representation of a kind of percolate from garbage filling field membrane concentration of the utility model liquid evaporation equipment.
In accompanying drawing, the list of parts representated by each label is as follows:
1, coagulation basin, 2, flocculation basin, 3, settling tank, 4, intermediate pool, 5, evaporation equipment, 6, agitator, 7, mud collection tube.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, the pretreatment unit of a kind of percolate from garbage filling field membrane concentration of the utility model liquid evaporation equipment, comprise coagulation basin 1, flocculation basin 2 and settling tank 3, described coagulation basin 1 is successively by pipeline communication flocculation basin 2 and settling tank 3, and the liquid outlet of described settling tank 3 is communicated with evaporation equipment 5; Described coagulation basin 1 is provided with landfill percolate concentrated solution entrance.
As shown in Figure 1 in certain embodiments, in described flocculation basin 2, agitator 6 is installed.
The pretreatment unit of the utility model a kind of percolate from garbage filling field membrane concentration liquid evaporation equipment described above, also comprise intermediate pool 4, described intermediate pool 4 to be connected between described settling tank 3 with described evaporation equipment 5 and to be communicated with respectively with described evaporation equipment 5 with described settling tank 3.
This device solves simple strainer and concentrates liquid to the percolate containing materials such as a large amount of particulate, suspended substance, colloid, calcium, magnesium and process, and causes filter stoppage serious, cisco unity malfunction; And not thorough due to what filter, accelerate the fouling of back segment vapo(u)rization system, cause the problem of equipment cisco unity malfunction.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
