Abstract
The invention provides a method for processing arsenic polluted water body by enrichment adsorption coupling, which is to place a processing unit in the polluted water body. The processing unit comprises floating bodies, plants and adsorbents; the floating bodies are bamboo rafts made of moso bamboo; the plants select emergent aquatic plants which can enrich arsenic and are fixed on the surfaces of the floating bodies to grow in a floating manner; the adsorbents are contained in an absorbing bag which is hung under the floating bodies; the absorbing bag hung under the bamboo rafts absorbs harmful substance through the adsorbents in a deep layer of the water body; the roots of the floating plants are underwater, which enrich arsenic through the action of plant roots to achieve the purpose of purifying water body. The method of the invention has simple operation, low cost, environmental protection and no pollution; the arsenic removing effect is good by combining the enrichment of plantsand absorption of the absorbents; and the introduction of the plants improves the landscape of the water body and beautifies the environment.
Description
Technical field
The present invention relates to a kind of water body treatment process of arsenic contamination, belong to the water body purification technical field.
Background technology
River and lake arsenic contamination incident happen occasionally in recent years, processing for these arsenic polluted water bodies, common way is from extraneous water transfer contaminated water body to be diluted, but dilution method has certain requirement to hydrology water conservancy condition, wayward, be difficult to obtain ideal effect in the river, during the pollution treatment of lake, and still might produce exceed standard " polluting group " and be advanced into the downstream.In addition, can and be deposited to the river bed with arsenic absorption though in polluted-water, add arsenic-removing adsorption agent, finish improvement, the qualified discharge of polluted river water, but settled contain arsenic river silt still exist to peripheral soil and groundwater seepage and discharge once more arsenic may, the disposal that contains arsenic river silt has been increased undoubtedly the expense of handling.
Summary of the invention
The present invention is directed to the deficiency that existing arsenic polluted water body treatment technology exists, a kind of method of simple to operate, cost is low, removal effect is good processing arsenic polluted water body by enrichment adsorption coupling is provided.
The method of processing arsenic polluted water body by enrichment adsorption coupling of the present invention is that processing unit is placed contaminated water body, this processing unit comprises buoyancy aid, plant and sorbent material, buoyancy aid is the bamboo raft of being made by mao bamboon, plant is selected the plant that arsenic is had accumulation ability for use, these plants are fixed on above the buoyancy aid, floating growth, sorbent material is contained in the absorbent packet, absorbent packet is suspended on below the buoyancy aid, the absorbent packet that hangs on the bamboo raft below passes through the adsorbents adsorb objectionable impurities in the deep layer of water body, the root of pleuston by the effect enrichment arsenic of roots of plants, reaches the purpose of purifying water body under the water surface.
The making processes of described processing unit may further comprise the steps:
A. choose the mao bamboon that diameter is 15cm-20cm, make bamboo raft with rattan binding, with this bamboo raft as buoyancy aid;
B. on the mao bamboon of bamboo raft, dig the plantation hole every the root cutter, the through hole of plantation hole for communicating up and down, pitch-row is 10cm-15cm, bore dia is 5cm-6cm;
C. with plant apart from the nearer stem's sponge wrapping of root, be fixed in then in the plantation hole on the bamboo raft mao bamboon, the root of plant stretches below bamboo raft, for pleuston directly put into the plantation hole.
D. hang the absorbent packet be filled with sorbent material below the mao bamboon of not planting the hole of bamboo raft, the spacing on every mao bamboon between the absorbent packet is 10cm-15cm.
It is γ-Al of 1mm-2mm that described sorbent material adopts particle diameter
2O
3Or zeolite.
The present invention is simple to operate, and cost is low, and is environment friendly and pollution-free, the enrichment of associating plant and the adsorption of sorbent material, and effect of removing arsenic is good, and the introducing of plant has improved water landscape, has beautified environment.

Embodiment
The method of processing arsenic polluted water body by enrichment adsorption coupling of the present invention at first is to make several processing units as shown in Figure 2, and the making processes of this processing unit may further comprise the steps:
A. choosing diameter is the mao bamboon 1 of 15cm-20cm, makes a bamboo raft as shown in Figure 1 with rattan 2 binding, with this bamboo raft as buoyancy aid;
B. dig plantation hole 3 every the root cutter on the mao bamboon of bamboo raft, plantation hole 3 is the through hole that communicates up and down, and pitch-row is 10cm-15cm, and bore dia is 5cm-6cm;
C. with plant 4 apart from the nearer stem's sponge wrapping of root, be fixed in then in the plantation hole 3 on the bamboo raft mao bamboon, the root of plant stretches below bamboo raft, directly puts into the hole for pleuston.Plant 4 is selected for use has accumulation ability to arsenic, can select floating plant for use, as Shortleaf Kyllinga Herb, Herba potamogetonis distincti etc.
D. hang the absorbent packet 5 be filled with sorbent material 6 below the mao bamboon of not planting hole 3 of bamboo raft, the spacing on every mao bamboon between the absorbent packet 5 is 10cm-15cm.It is γ-Al of 1-2mm that sorbent material 6 adopts particle diameter
2O
3Or zeolite etc.Then, the processing unit of making is placed contaminated water body, the absorbent packet that hangs on the bamboo raft below arrives the deep layer of water body, and the root of emergent is under the water surface, by the effect enrichment arsenic of emergent root, by the adsorbents adsorb impurity in the absorbent packet.Also available rope with four jiaos of bamboo raft with water in or on the bank spud pile be connected, with fixing entire treatment unit, improve the ability of wind and wave resistance.
Major advantage of the present invention has:
(1) choose bamboo raft that mao bamboon makes as floating body, environmental protection is pollution-free.
(2) processing unit is made simply, and cost is low.
(3) the present invention unites the enrichment of plant and the suction-operated of adsorbent, and effect of removing arsenic is good.
(4) introducing of plant has improved water landscape, has beautified environment.
