The utility model content
The technical problems to be solved in the utility model provide a kind of can efficient absorption heavy metal contaminants, effectively decomposing organic pollutant, horizontal drowned flow artificial wet land that wastewater purification efficiency is high.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of horizontal drowned flow artificial wet land, comprise a body, its gordian technique is that a body both sides is the gravel district, be respectively water inlet gravel district and water outlet gravel district, the centre is the matrix district, bottom, matrix district is provided with micropore aeration pipe, the matrix district is followed successively by coarse sands layer from top to bottom, artificial mixolimnion, coarse sands layer, the diaphragm that is provided with is distinguished matrix and is slit into snakelike water stream channel, artificial mixolimnion kind is implanted with dark root system plant, bed body bottom is provided with dredging flow groove, the dredging flow groove bottom land is provided with waterproof layer, and dredging flow groove groove top is positioned at position, water outlet gravel district and is provided with porous disc, and the dredging flow groove groove pushes up all the other positions and is provided with waterproof layer.
Preferably, micropore aeration pipe is the porous PVC aeration tube, and micropore aeration pipe is connected with the underwater jet aeration machine.
Preferably, above-mentioned artificial mixolimnion is mixed by vermiculite, zeolite, cinder, and artificial mixolimnion thickness is at least 20cm, above closely knit, loose below.
Preferably, above-mentioned water inlet gravel district gravel particle diameter is 8-15mm, and water outlet gravel district gravel particle diameter is 2-4cm.
Preferably, above-mentioned coarse sands layer grain diameter is 2-7mm.
Adopt the beneficial effect that technique scheme produced to be: to be laid with matrix and micropore aeration pipe in the horizontal drowned flow artificial wet land, carry out little aeration by micropore aeration pipe to the oxygen supply of horizontal drowned flow wetland, effective increase system oxygen level, improved the reaction purification efficiency of root system of plant and microorganism species, the efficient processing absorbs heavy metal contaminants, decomposing organic pollutant, the diaphragm guiding sewage that is provided with carries out flowing of vertical and horizontal direction at the horizontal drowned flow wetland, increase the clarification time, improve purification efficiency; Behind the sewage process horizontal drowned flow wetland, organic pollutant and heavy metal contaminants can reduce in a large number, and inorganic pollutant also can further reduce.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1, accompanying drawing 2, the both sides of horizontal drowned flow artificial wet land are the gravel district, wherein a side is water inlet gravel district 9, opposite side is water outlet gravel district 10, the zone that is surrounded by water guide dividing plate 11 is not filled up in water outlet gravel district 10, water outlet adds the part gravel can effectively prevent the system obstruction, is convenient to water and better discharges.Matrix is made up of coarse sands layer 2, artificial mixolimnion 3, coarse sands layer 4 from bottom to top, and artificial mixolimnion 3 is mixed by zeolite, vermiculite, cinder and forms.Micropore aeration pipe 5 is mesh structural porous PVC breather line, can carry out little aeration by micropore aeration pipe 5 to the oxygen supply of horizontal drowned flow wetland by the underwater jet aeration machine, can more effectively increase system's oxygen level, improve the reaction purification efficiency of root system of plant and microorganism species, the efficient processing absorbs heavy metal contaminants, decomposing organic pollutant.The plant translocation that mainly relies on horizontal drowned flow wetland commonly used realizes vertical oxygen compensation, and compensation rate is little.The multiple enriching plant of dark root system plant 1 main configuration, as reed, Stenocalyx micheli, calamus, Scirpus tabernaemontani or the like, the integrated configuration enriching plant is by the removal purpose of all kinds of enriching plants for heavy metal contaminants in the powerful absorptive function realization sewage of heavy metal contaminants.In this horizontal drowned flow wetland, can form plant---the micropopulation ecosystem, a large amount of superior microorganism groups can appear in matrix and root system, rely on microorganism species further decomposing organic pollutant and heavy metal contaminants.Behind this horizontal drowned flow of sewage process wetland pond, organic pollutant and heavy metal contaminants can reduce in a large number, and inorganic pollutant also can further reduce.
Referring to accompanying drawing 1, coarse sands layer 2 and coarse sands layer 4 adopt the coarse sand of grain diameter at 2-7mm, and the water inlet gravel selects particle diameter at 8-15mm, and it is 2-4cm that the gravel of water outlet is selected particle diameter.Artificial mixolimnio 3 thickness are at least 20cm, when inserting in the horizontal drowned flow wetland pond, according to top loose below closely knit, above particle tiny, below the thick principle of particle.10 bottoms, water outlet gravel district are provided with porous disc, and the sewage after the processing imports dredging flow groove 7 from here, and the rest part that the porous disc position is removed at the top of dredging flow groove 7 is provided with waterproof layer 6, and the dredging flow groove bottom also is equipped with waterproof layer 8.
Sewage at first passes through water inlet gravel district 9 during work, then under the guiding of water guide dividing plate 11, in the horizontal drowned flow wetland, carry out flowing of vertical and horizontal direction, can increase the clarification time, improve purification efficiency, enter water outlet gravel district 10 again at tail end, the porous disc below water outlet gravel district 10 imports horizontal drowned flow wetland pond sluicing groove 7, discharged by water discharge pipe, the water of discharge can recycle.The utility model can be formed composite artificial marsh sewage treatment system in conjunction with existing vertical-flow wetland or surface current wetland technology, has better action.
