Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with drawings and Examples, the present invention will be described in further detail.
As shown in figure 1, the revetment system of water body in lake protection of the present invention based on permeable reactive barrier includes water body in lake 1, in addition to packing layer 2, permeable reactive barrier 3 and impervious barrier 4；The permeable reactive barrier 3 faces the water body in lake 1 and uprightly set, the impervious barrier 4 sets on land and keeps a small distance with the permeable reactive barrier 3, it is described filler layer 2 between permeable reactive barrier 3 and impervious barrier 4, described filler layer 2 can accommodate a variety of fillers.
The permeable reactive barrier 3 is diaphragm wall type or funnel-channel-style, densely arranged on wall to have permeable hole, and the combination of any one or more material in armored concrete, block stone, plant these three materials can be used by building permeable reactive barrier 3.
Described filler layer 2 can change different types of filler according to the property of water pollutant, and described filler layer 2 is filled with reaction medium.The reaction medium is combined by any one or more in following：Zero-valent Iron, apatite, zeolite, slag, organic matter clay, microbial nutrition carrier.
The impervious barrier 4 uses waterproof isolation-type material.Building the impervious barrier 4 can use the one or more in antiseepage film, waterproof blanket, geomembrane, geotextiles, GSZ, drain bar, drainage network to combine.
The construction method of the above-mentioned water body in lake protection revetment based on permeable reactive barrier comprises the following steps：
A. the water body bank more than the organic wastewater discharge capacity, one impervious barrier 4 is set in land area that is parallel with the bank of water body in lake 1 and having a small distance, to prevent Lake Water seepage；The impervious barrier 4 has antiseepage barriers function, prevents organic wastewater from flowing back；
B. and then on the bank of water body in lake 1 permeable reactive barrier 3 is established；Permeable reactive barrier 3 can retain the organic wastewater that land is come, and prevent the waste water of land from flowing directly into water body in lake 1, to reduce the contaminant capacity of water body in lake 1；
C. reaction medium microbial nutrition carrier is selected as inserts come organic wastewater property according to land, the inserts is inserted between the permeable reactive barrier 3 and impervious barrier 4 and forms packing layer 2 for filtering and handling riverbank water.And the ground surface Grass cover on described filler layer 2 is to beautify the environment.
Embodiment 1：Pollution sources are based on organically-polluted water, then from microbial nutrition carrier as the filler in described filler layer 2.Then the organically-polluted water from land first flows into the region of packing layer 2, the microbial degradation organic pollution in packing layer 2 on nutrition carrier.By the biological agent of reaction medium in packing layer 2, water body in lake 1 is entered by permeable reactive barrier 3 again after water is first purified.
Embodiment 2：Pollution sources are based on the next waste water from dyestuff in land, from slag and zeolite as the filler in described filler layer 2.Then the dye discoloration water from land first flows into the region of packing layer 2, slag and zeolite adsorption and lake pollutant in packing layer 2.By the physical action of reaction medium in packing layer 2, water body in lake 1 is entered by the permeable reactive barrier 3 again after water is first purified.
Embodiment 3：Pollution sources are the filler in described filler layer 2 from zero-valent iron particle based on heavy metal wastewater thereby.Then the heavy metal-containing polluted water from land first flows into the region of described filler layer 2, and the zero-valent iron particle in packing layer 2 has reproducibility, the valence state of heavy metal can be reduced, so as to reduce the migration of heavy metal contaminants or toxicity.By the chemical action of packing layer 2, water body in lake 1 is entered by permeable reactive barrier 3 again after water is first purified.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert that the specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, should all be considered as belonging to protection scope of the present invention.
