Abstract
The invention provides a multi-stage treatment and purification process for groundwater pollution. The multi-stage treatment and purification process for the groundwater pollution comprises an aeration biological fluidization tank, a filtering tank and a reaction tank which are sequentially connected from left to right, an extraction tube is communicated with the bottom of an extraction well, the extraction tube is connected to an extraction pump on the earth surface, the extraction pump is connected to the aeration biological fluidization tank by virtue of a pipeline, the reaction tank is connected with a delivery pump by virtue of a delivery pipe, and a drain pipe connected with the other end of the delivery pump extends inside an infiltration channel. The multi-stage treatment and purification process for the groundwater pollution has the beneficial effects that ammonia nitrogen and halogenated hydrocarbon pollutants in groundwater can be effectively removed by adopting a multi-stage treatment method aiming at the composition characteristic of the groundwater infiltrated by garbage pollutant, so that the groundwater can meet the water quality standard for drinking water, and the multi-stage treatment and purification process for the groundwater pollution is reasonable in design, simple in structure, safe and reliable, easy in operation and easy in maintenance and has popularization and application values.
Description
Technical field
The present invention relates to contaminated underground water recovery technique, relate in particular to a kind of groundwater pollution multiple-stage treatment purification process.
Background technology
Along with the develop rapidly in city, the amount of taking in rubbish is more and more, and refuse tip is also more and more, this thing that just inevitably can produce refuse leachate polluted underground water occurs, these problems are constantly aggravated, and make this with regard to few underground water, and that can directly be used by people becomes still less.The content that in refuse leachate is mainly ammonia nitrogen and halohydrocarbon is higher, become the principal element of polluted underground water, existing treatment system is mainly by isolation technology, chemical treatment and vacuum extraction etc. in water, working cost is high, complex structure, but still do not reach very desirable treatment effect, underground water also needs further purification just can reach the standard of tap water.
Summary of the invention
The object of the invention is to overcome weak point of the prior art, a kind of groundwater pollution multiple-stage treatment purification process is provided.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
A kind of groundwater pollution multiple-stage treatment purification process, comprise the ABFT, filtering basin and the reaction tank that from left to right connect successively, extraction tube is communicated to the bottom of extraction well, extraction tube is connected in extraction pump on earth's surface, extraction pump is connected to ABFT by pipeline, reaction tank is connected with transferpump by transfer lime, the water shoot being connected with the transferpump the other end extends to infiltration trench inside, extending oil stopping composition in reaction tank, stopping composition is the mixture of fermentation bark and sand, and the volume ratio of ferment bark and sand is more than or equal to 1:1.
Further described ABFT bottom is provided with micro-pore aeration system, the molecular stuffing of inner many outages of extending oil is microorganism carrier, the material that carrier is used is polyurethane sponge, and filtering basin top kind is implanted with water purification plant, and what water purification plant adopted is the Salicaceous Plants of well developed root system.
The present invention has following beneficial effect:
Groundwater pollution multiple-stage treatment purification process of the present invention, for the composition characteristic of underground water of refuse pollution thing infiltration, by multistage treatment method, ammonia nitrogen and contaminated with halogenated hydrocarbons thing in can effective removal underground water, make underground water can meet water quality standard for drinking water, reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, there is the value of promoting the use of.Accompanying drawing explanation
Fig. 1 is multiple-stage treatment purification process structure iron provided by the present invention.
Nomenclature:
1: ABFT 2: filtering basin 3: reaction tank 4: infiltration trench
5: water purification plant 6: stopping composition 7: carrier 8: extraction pump 9: extraction tube
10: pipeline 11: extraction well 12: transfer lime 13: transferpump 14: water shoot
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As one embodiment of the present invention, consult Fig. 1, a kind of groundwater pollution multiple-stage treatment purification process, comprise the ABFT 1 from left to right connecting successively, filtering basin 2 and reaction tank 3, extraction tube 9 is communicated to the bottom of extraction well 11, extraction tube 9 is connected in extraction pump 8 on earth's surface, extraction pump 8 is connected to ABFT 1 by pipeline 10, reaction tank 3 is connected with transferpump 13 by transfer lime 12, the water shoot 14 being connected with transferpump 13 the other ends extends to infiltration trench 4 inside, the interior extending oil stopping composition 6 of reaction tank 3, stopping composition 6 is the mixture of fermentation bark and sand, the volume ratio of fermentation bark and sand is more than or equal to 1:1.
Further described ABFT 1 bottom is provided with micro-pore aeration system, the molecular stuffing of inner many outages of extending oil is microorganism carrier 7, the material that carrier 7 is used is polyurethane sponge, filtering basin 2 top kinds are implanted with water purification plant 5, and what water purification plant 5 adopted is the Salicaceous Plants of well developed root system.
During work, at underground water, be subject to the region of the contaminants such as ammonia nitrogen or halohydrocarbon, beat a bite extraction well 11, the extraction tube 9 of the extraction pump 8 on earth's surface by being communicated to extraction well 11 bottoms to earth's surface, and delivered to ABFT 1 by pipeline 10 underground water contaminated underground water extracting.Carrier 7 upslides in ABFT 1 are placed with complex microorganism bacterial classification, and microorganism obtains sufficient oxygen in aeration process, ammonia nitrogen pollutant direct oxidation, are nitric nitrogen, and this process can be disposed most ammonia nitrogen pollutant.The underground water that is at this time also dissolved with a lot of oxygen enters into filtering basin 2, and under aerobic condition, remaining ammonia nitrogen pollutant is further oxidized to nitric nitrogen.Filtering basin 2 top kinds are implanted with water purification plant 5, are the Salicaceous Plants of well developed root system, can not only purification of ground water, can also consume the oxygen in water, and reduce the oxygen dissolving in underground water, guarantee that reaction tank 3 is anaerobic environment.In the reaction tank 3 of anaerobic environment, nitric nitrogen completes denitrification, nitrate-nitrogen reduction becomes nitrogen, volatilize away voluntarily, anaerobion in simultaneous reactions pond 3, can be the oxidation state pollutent deoxidization, degradation of halohydrocarbon one class, the organic matter in fermentation bark can be used as electron donor(ED), improves the speed of reduction process.By the underground water of processing, be transferred pump 13 and be transported to earth's surface by transfer lime 12, then be discharged in infiltration trench 4 by water shoot 14 like this, so just completed the process that a whole beneath polluted water is processed, simply effective, processing efficiency is high.
In sum; the present invention is only illustrated an embodiment of groundwater pollution multiple-stage treatment purification process; but the invention is not restricted to this; it will be appreciated by those skilled in the art that in the situation that do not depart from the protection domain that claims of the present invention record and can change arbitrarily and revise.
