Description
Technical field
The present invention relates to a kind of artificial marsh sewage treatment system, more particularly to one kind to be used to purify antimony ore Tailings Dam alkalescence
The artificial wet land system of waste water；Belong to field of waste water treatment.
Background technology
Tailings caused by antimony ore exploitation is piled up in Tailings Dam, under the eluviation of beneficiation wastewater and rainwater, generates big
Amount is rich in the tailings reservoir wastewater for poisoning element sb.To avoid sulfide-oxidation in Tailings Dam from producing acid waste water, antimony ore is looked forward at present
Industry adds lime to lift the pH of tailings reservoir wastewater generally in antimony ore Tailings Dam, but this processing method can not significantly reduce
Sb concentration in antimony ore tailings reservoir wastewater；Therefore the exclusive alkaline waste water rich in Sb of antimony ore Tailings Dam is formd.China at present
Also without the practicality treatment technology for antimony ore Tailings Dam alkaline waste water.
The content of the invention
In order to overcome defect present in prior art, the present invention is intended to provide a kind of maintenance management is simple, operating cost
Low, the sustainable antimony ore Tailings Dam alkaline waste water artificial wetland purifying system for effectively repairing water body.
To achieve these goals, the present invention uses following technical scheme：It includes the multistage connected with multifeed clarifier
Microorganism wetland reduces pond；The multifeed clarifier is made up of at least two sedimentation basins of sequential communication, more level microbes
Wetland reduces pond and is made up of at least three microorganism wetlands reduction pond of sequential communication；Have in each microorganism wetland reduction pond some
The core wall of interleaved arrangement, place mat has the first stalk layer, organic fertilizer layer, the successively for the bottom of pond in each microorganism wetland reduction pond
Two stalk layers and soil horizon.
The surface construction of soil horizon has the low bank of earth between fields of some interleaved arrangements；Kind is implanted with cattail on the low bank of earth between fields；Each microorganism is wet
The length × width × height in ground reduction pond is 7.8m × 5.4m × 1.2m, and the first stalk layer thickness is 5cm, organic fertilizer thickness degree is
20cm, the second stalk layer thickness are 10cm, soil horizon thickness is 20cm；The low bank of earth between fields is highly 45cm.
Compared with the prior art, the present invention is by adopting the above-described technical solution, can be net according to artificial swamp microorganism
Change the principle of harmful substance in water body, the bottom of pond in microorganism wetland reduction pond has laid the first stalk layer, organic fertilizer layer, second
Stalk layer and soil horizon；Wherein, the decomposition of stalk and organic fertilizer can provide nutrient for the microorganisms in soil, promote micro- life
Thing is quickly bred, and then by the Sb in alkaline waste water by micro-reduction and mineralization, make the effective mineralisings of solubilised state Sb and
Precipitation.In addition, in the root system and its secretion, microorganism epidermis and the adsorbable alkaline waste water of remains of water plant-cattail prosperity
Antimony, reduce further the Sb concentration in water body.Moreover, as a result of multifeed clarifier, therefore can be to alkalescence
Waste particles thing carries out multi stage precipitation processing, so as to effectively promote the Fe in alkaline waste water2+It is oxidized to Fe3+, and form Fe (OH)3
Al (OH) in colloid, with water body3The Sb in adsorbed water body together such as colloid.4th, if due to the surface construction in soil horizon
The low bank of earth between fields of dry interleaved arrangement, therefore alkaline waste water can be made along snakelike or S-shaped meandering flow, extend waste water flowing when
Between so that physical sedimentation, chemical oxidation, biological adsorption, micro-reduction are more abundant, so as to further reduce in water body
Sb concentration, improve water quality.
The present invention have it is simple in construction, construction investment is small, substantially without regular maintenance and management, it is not necessary to which any electric power is set
Standby, operating cost is low, sustainable the advantages that repairing water body.
Field pilot-scale experiment shows：After antimony ore Tailings Dam alkaline waste water is processed by the invention, Sb contents are from 3090 in water body
The abatement amount that ± 1258 μ g/L are substantially reduced to 753.2 ± 386.4 μ g/L, Sb respectively reaches 76.3 ± 2.6%；Water quality reach or
Close to the limit value about Sb in China's industrial water drainage standard（500μg/L）, water quality significantly improves.
Brief description of the drawings
Fig. 1 is the top view of the present invention；
Fig. 2 is the schematic diagram of 90 ° of A-A section views rotate counterclockwise in Fig. 1.
In figure：Microorganism wetland reduction pond 1, the low bank of earth between fields 2, core wall 3, sedimentation basin 4, mozzle 5, soil horizon 6, the second stalk
Layer 7, organic fertilizer layer 8, the first stalk layer 9.
Embodiment：The invention will be further described with specific embodiment below in conjunction with the accompanying drawings：
As shown in Fig. 1~2：Multifeed clarifier is connected by mozzle 5 by two sedimentation basins 4 and formed, and more level microbes are wet
Ground reduces pond and formed by the three microorganism wetlands reduction pond 1 being arranged in order from right to left by the sequential communication of mozzle 5；It is located at
That microorganism wetland reduction pond 1 of the rightmost side is connected by other mozzle 5 with that sedimentation basin 4 positioned at left side.Respectively
Place mat has the first stalk layer 9, organic fertilizer layer 8, the and of the second stalk layer 7 to the bottom of pond in microorganism wetland reduction pond 1 successively from bottom to top
