Abstract
The utility model discloses a kind of infiltration structure for repairing heavy metal pollution, it comprises soil moved in to improve the original layer (5), be arranged on the permeable formation of soil moved in to improve the original layer (5) bottom, be arranged on the collector pipe (1) of permeable formation inside, described permeable formation is divided into three layers, be respectively from top to bottom infiltration ground floor (4), the infiltration second layer (3) and the 3rd layer (2) of infiltration, the packing material size of described permeable formation every one deck from top to bottom increases gradually, described collector pipe (1) is positioned at the 3rd layer (2) of infiltration, and on collector pipe (1), offer multiple inlet openings (6), the packing material size of described infiltration the 3rd layer (2) is greater than the diameter of inlet opening (6).The beneficial effects of the utility model are: it can effectively tackle the suspended material in soil moved in to improve the original layer, can filter the ponding in soil moved in to improve the original layer with different filtering velocitys, have ensured the normal growth of plant.
Description
Technical field
The utility model relates to heavy metal pollution reparation, particularly a kind of infiltration structure for repairing heavy metal pollution.
Background technology
Soil pollutes and is broadly divided into inorganic pollution and the large class of organic pollution two.Inorganic pollution mainly comprises acid, alkali, heavy metal, the compound of salt, radioactive element caesium, strontium, containing the compound of arsenic, selenium, fluorine etc.Organic pollution mainly includes machine agricultural chemicals, phenols, cyanide, oil, synthetic detergent, 3,4-BaP and harmful microorganism of being brought by municipal sewage, mud and barnyard manure etc.When containing hazardous substance in soil too much, exceed the self-purification capacity of soil, will cause that composition of the soil, 26S Proteasome Structure and Function change, microbial activities is suppressed, harmful substance or its catabolite accumulate gradually by " soil → plant → human body " in soil, or be indirectly absorbed by the body by " soil → water → human body ", reach the degree being detrimental to health.
In heavy metal pollution repair process, too many when ponding in soil moved in to improve the original layer, can cause oxygen content to reduce, thereby affect the growth of plant, therefore need to arrange permeable formation, ponding is concentrated to outwards discharge.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of infiltration structure for repairing heavy metal pollution that can effectively tackle suspended material and have different filtering velocitys is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of infiltration structure for repairing heavy metal pollution, it comprises soil moved in to improve the original layer, be arranged on the permeable formation of soil moved in to improve the original layer bottom, be arranged on the collector pipe of permeable formation inside, described permeable formation is divided into three layers, be respectively from top to bottom infiltration ground floor, the 3rd layer of the infiltration second layer and infiltration, the packing material size of described permeable formation every one deck from top to bottom increases gradually, described collector pipe is positioned at the 3rd layer of infiltration, and on collector pipe, offer multiple inlet openings, the packing material size that described infiltration is the 3rd layer is greater than the diameter of inlet opening.
One end of described collector pipe is provided with blanking cover, and blanking cover and collector pipe are tightly connected.
Described collector pipe is PVC water pipe, and the inlet opening diameter on collector pipe is 10mm.
The utlity model has following advantage: infiltration structure of the present utility model, permeable formation is divided into three layers, effectively tackle the suspended material of soil moved in to improve the original layer, ensured the quality of soil in soil moved in to improve the original layer, the packing material size difference that the every one deck of permeable formation is used, thereby there is different filtering velocitys, ponding in soil moved in to improve the original layer, enters collector pipe after filtering by permeable formation, then discharges, avoid too many because of ponding in soil moved in to improve the original layer, ensured the normal growth of plant.
Brief description of the drawings
Fig. 1 is permeable formation structural representation;
Fig. 2 is collector pipe structural representation;
In figure, 1-collector pipe, the 3rd layer of 2-infiltration, 3-permeates the second layer, and 4-permeates ground floor, 5-soil moved in to improve the original layer, 6-inlet opening, 7-blanking cover.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of infiltration structure for repairing heavy metal pollution, it comprises soil moved in to improve the original layer 5, soil moved in to improve the original layer 5 is soil of good quality, its objective is and provide a unpolluted environment for plant normal growth, be arranged on the permeable formation of soil moved in to improve the original layer 5 bottom, be arranged on the collector pipe 1 of permeable formation inside, described permeable formation is divided into three layers, be respectively from top to bottom infiltration ground floor 4, the 3rd layer 2 of the infiltration second layer 3 and infiltration, the packing material size of described permeable formation every one deck from top to bottom increases gradually, described collector pipe 1 is positioned at the 3rd layer 2 of infiltration, and on collector pipe 1, offer multiple inlet openings 6, the packing material size that described infiltration is the 3rd layer 2 is greater than the diameter of inlet opening 6.
Permeable formation is piled up and is formed by cobble and gravel, permeable formation thickness 20cm, permeable formation is mainly interception suspended material, the packing material size difference used according to permeable formation, realize different filtering velocitys, wherein: the particle diameter (mm) of d1, d2, d3-each layer of filler, is respectively the packing material size that permeates ground floor 4, the infiltration second layer 3, permeates the 3rd layer 2 from top to bottom; The particle of di-soil moved in to improve the original layer calculates particle diameter (mm), and in the present embodiment, the granular size between each layer is: d1=7-8di, d2/d1=d3/d2=2-4.
In the present embodiment, as shown in Figure 2, one end of collector pipe 1 is provided with blanking cover 7, blanking cover 7 is tightly connected with collector pipe 1, described collector pipe 1 is PVC water pipe, and inlet opening 6 diameters on collector pipe 1 are 10mm, and permeating the 3rd layer of 2 packing material size d3 should be than inlet opening 6 slightly larger in diameter on collector pipe 1.
Claims (3)
