Description
Technical field
The present invention relates to contaminated groundwater remediation technology, particularly relate to a kind of groundwater pollution multiple-stage treatment purification process.
Background technology
Along with the develop rapidly in city, the amount of storage rubbish gets more and more, and refuse tip also gets more and more, this thing just inevitably producing refuse leachate polluted underground water occurs, these problems are constantly aggravated, and make this just few underground water, what directly can be used by people becomes less.In refuse leachate, mainly the comparision contents of ammonia nitrogen and halohydrocarbon is high, become the principal element of polluted underground water, existing treatment system is primarily of 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, provide a kind of groundwater pollution multiple-stage treatment purification process.
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 be 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 fermentation bark and sand is more than or equal to 1:1.
Micro-pore aeration system is provided with bottom further described ABFT, the molecular stuffing of inner extending oil many outages is microorganism carrier, the material that carrier uses 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, have been directed to the composition characteristic of the underground water of waste lump infiltration, by multistage treatment method, effectively can remove the ammonia nitrogen in underground water and contaminated with halogenated hydrocarbons thing, enable underground water meet water quality standard for drinking water, reasonable in design, structure is simple, safe and reliable, easy to use, be easy to safeguard, there is the value promoted the use of.Accompanying drawing explanation

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 connected 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, it is inner that the water shoot 14 be connected with transferpump 13 the other end extends to infiltration trench 4, extending oil stopping composition 6 in 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.
Micro-pore aeration system is provided with bottom further described ABFT 1, the molecular stuffing of inner extending oil many outages is microorganism carrier 7, the material that carrier 7 uses is polyurethane sponge, filtering basin 2 top kind is implanted with water purification plant 5, and what water purification plant 5 adopted is the Salicaceous Plants of well developed root system.
During work, the region of the contaminants such as ammonia nitrogen or halohydrocarbon is subject at underground water, beat a bite extraction well 11, the extraction pump 8 on earth's surface by being communicated to extraction tube 9 bottom extraction well 11 contaminated groundwater extraction to earth's surface, and delivers to ABFT 1 by pipeline 10 underground water.Carrier 7 upslide in ABFT 1 is placed with complex microorganism bacterial classification, and microorganism obtains sufficient oxygen in aeration process, and be nitric nitrogen ammonia nitrogen pollutant direct oxidation, this process can dispose most ammonia nitrogen pollutant.The underground water being 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 kind is implanted with water purification plant 5, is the Salicaceous Plants of well developed root system, can not only purification of ground water, can also consume the oxygen in water, reduces the oxygen dissolved in underground water, ensures 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 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.Like this by the underground water of process, 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, this completes the process of a whole beneath contamination data analysis, simply effectively, processing efficiency is high.
In sum; the present invention is only illustrated an embodiment of groundwater pollution multiple-stage treatment purification process; but the present invention is not limited thereto; it will be appreciated by those skilled in the art that and can change when not departing from the protection domain described in claims of the present invention arbitrarily and revise.
