Abstract
The invention discloses an artificial wetland system capable of removing heavy metal in livestock and poultry breeding wastewater and belongs to the technical field of treating wastewater in the livestock and poultry breeding industry. According to the artificial wetland system capable of removing the heavy metal in the livestock and poultry breeding wastewater, the livestock and poultry breeding wastewater is firstly mixed evenly in a water distribution box and then is evenly brought into a packed column with a packing layer through a water inlet pipe, and the hydraulic retention time is 2 hours; after the packed column of an artificial wetland becomes saturation through adsorption and the treatment effect is lost, the packed column is replaced in time. The artificial wetland system is capable of effectively removing the heavy metal Cd2+, Cr6+, Cu2+ and Mn2+ in the livestock and poultry breeding wastewater, is easy to operate, consumes no power and greatly saves operation and maintenance cost, and a whole artificial wetland wastewater treatment system can operate more efficiently and more stably. The occupied area is small, moving is convenient, and the artificial wetland system is more suitable for developed regions where land resources are in shortage. The treated livestock and poultry breeding wastewater can be directly discharged or reutilized.
Description
Technical field
The invention belongs to livestock culture industry technical field of waste water processing, what be specifically related to is that one can efficiently be removed livestock breeding wastewater heavy metal Cd

Background technology
Livestock and poultry breeding industry is a large leading industry of China's agricultural, and the quantity discharged of annual waste water exceedes 10,000,000,000 tons.Livestock breeding wastewater is the organic waste water of a class high density, contains multiple pollutant, has become the one of the main reasons that causes China's widespread pollution from the overuse of fertilizers and pesticides in rural area.Especially, because the extensive interpolation of heavy metal in animal-feed causes containing in waste water various heavy Cd
2+, Cr
6+, Cu
2+, Mn
2+deng, although total concentration is lower, larger to the potential hazard of environmental organism and human health.Therefore, in breeding wastewater, the removal of heavy metal has become the task of top priority of cultivation wastewater purification.
Artificial wet land system is as the follow-up advanced treatment unit of sewage purification, and its filler is selected with ingredients technical most important.Both at home and abroad about the report of Wastewater Treatment by Constructed Wetlands method is a lot, as disclosed patent " a kind of sewage water treatment method based on facultative biochemistry-strengthened artificial wet land " (CN 101979348A), this technology increases facultative biochemistry device on the basis of artificial swamp, not only increase investment and expend, and floor space is large; Disclosed patent " a kind of method and artificial swamp structure of sewage being carried out to advanced treatment " (CN 102249496A), this technology has increased other and has processed structure, structure to artificial swamp is arranged, although its entirety can improve treatment effect, but structure is comparatively complicated, floor space is larger, is not suitable for the developed regions that soil is in short supply.Also have in addition much reports about Performance of Constructed Wetlands Substrates technology, but general floor space is large, is not easy to dismounting and moves.Because the proterties difference of different industries waste water is larger, and same filler is also different to the removal effect of different pollutents, not yet has wetland distribution and the systematic account of removing for heavy metal in livestock breeding wastewater at present.
Summary of the invention
The object of the present invention is to provide a kind of artificial wet land system of removing heavy metal in livestock breeding wastewater, so that system reaches detachably, change filler convenient, be convenient to mobile transport, be more suitable for the application scenario of artificial swamp batching.
In order to solve above technical problem, concrete technical scheme of the present invention is as follows:
A kind of artificial wet land system of removing heavy metal in livestock breeding wastewater, it is characterized in that: comprise that upper end open and bottom position are provided with the filled column of water outlet B (5), lower position be provided with water outlet A distribution reservoir (1), be placed in filled column (5) inner bottom part packing layer, be positioned at the outlet valve (4) at position under filled column (5);
One end of described water pipe connects water outlet A, and the other end is positioned at the ingress of filled column (5) upper end, between filled column (5) and water water pipe, is detachable; On water pipe, be provided with under meter (2), be provided with water intaking valve (3) with approaching one end, filled column (5) ingress, upper end with the approaching one end of water outlet A.
Described packing layer comprises packing layer A (5-1), packing layer B (5-2) and packing layer C (5-3) from top to bottom; The material of described packing layer A (5-1), packing layer B (5-2) and packing layer C (5-3) is respectively natural zeolite, rice hull carbon, natural zeolite, and volume ratio is respectively 1:2:1.
the present invention has beneficial effect.System of the present invention is placed in packing layer in filled column, when packing layer no longer has after adsorption, the filled column of new packing layer is housed by direct replacing.In the time preparing burden for artificial swamp, can realize removable, and be convenient to installation, pore texture prosperity, pile close degree and water permeability good, and the packing specific area that uses large, high adsorption capacity, Stability Analysis of Structures, has improved effective processing volume of system sewage, the treatment effect of sewage is better, particularly counterweight Metal Ions Cd
2+, Cr
6+, Cu
2+, Mn
2+there is good adsorption effect.In addition, this system operation is simple, and system is detachable, changes filler convenient, and floor space urine is in movement, and not consumption of power, has saved operation and maintenance cost greatly, makes the operation of efficient stable more of whole artificial marsh sewage treatment system.
