Description
Technical field
The utility model relates to the aqueous vapor adjusting device that a heavy metal species willow absorbs.
Background technology
Along with fossil energy is day by day exhausted, as the wooden energy woods of biomass energy because of environmental friendliness, renewable and be subject to extensive concern.Wooden energy woods is the forest plantation by obtaining the energy to wooden carbonization, liquefaction and gasification.Willow tall and big dry straight, growth is fast, easily results and breeding, has become the important species of building short circulation phase energy forest.For many years, heavy metal environmental emission amount increases (if cadmium (Cd) content in the wetland bed mud of Shan Dong Altar-inside-ancestral-temple river is up to 4.6mgkg-1) year by year.Different from organic contamination, huge sum of money accessory enriching, difficult degradation and irreversibility, and distribution is wide, strong toxicity.
Poplar root, dry, branch all absorb enriching heavy metal, plant willow energy forest, removes and reclaim heavy metal while development energy forest in heavy metal pollution, also non-secondary pollution while obtaining ecology, economic benefit.
But Poplar Cultivation mostly is the poor marginal land of land occupation condition, as riverbank (beach), mine, often cause undergrowth; The absorption efficiency of willow heavy metal changes to some extent because of heavy metal kind, soil physico-chemical property; Growth of poplar is larger by the impact of low temperature, arid.This invention is bionical object with forest soil and plant structure, heavy water, controlled atmosphere joint with the contradiction solving willow Metal uptake efficiency and growth.Namely adsorption efficiency is improved by the design of the adsorption module such as heavy metal and nutrient, between disparate modules, mutual permutation and combination creates good matrix environment promotion root growth, select the Poplar Varieties of high absorbent capacity, and then control by moisture the absorption efficiency and the absorptive amount that increase willow heavy metal.
Utility model content
The utility model provides the aqueous vapor adjusting device that a heavy metal species willow absorbs, for column structure, comprise absorbent core and fixing protective layer and tank, it is characterized in that: absorbent core is in fixing protective layer, the horizontal arrangement of each absorbent core, the space of 2-4cm is left between the absorbent core heart arranged in parallel, different absorbent core is staggeredly placed, form vapor channel, boundary layer is formed between the absorbent core of different layers, the one end of the column structure that absorbent core and fixing protective layer are formed is fixed in tank and forms cultivation post, cultivation post is positioned in heavy-metal contaminated soil stirring pool, stirring pool is furnished with self priming pump, sewage containing heavy metal is watered to form the circulatory system downwards above cultivation post, poplar-branch cuttage is in absorbent core, on point, in, lower three layers, every layer of 4-5 direction is evenly distributed.
The selection of Adsorption of Heavy Metals material, as clay, perlite, weeds, willow fallen leaves, maize straw etc.
The combination of module divides single combination and mixed type; Mode is divided into Stochastic sum rule.The permutations and combinations of module: single type is as careless brick, water body, gas.Mixed type is the combination of above-mentioned module.Combination is Stochastic sum rule.Principle combinations is divided into planar layer, vertical demixing and plane and the vertical type that combines.
Table: different sorbing material is on the impact of nitrogen and heavy metal (lead) adsorption effect and growth of poplar
The utility model advantage: material easily obtains; Installation cost is low; Auto-control; Bio-diversity is protected; Take into account economy and ecological benefits.If content of beary metal declines 30%, willow year increment increases by 15%; After plant running 1 ~ 2 cycle (1 ~ 2 year), heavy metal content in soil is than contrast decline 40% ~ 60%; Due to landfill technique tool diversity and complexity, current extraction benefit will be greater than 2.5:1 with the ratio of cost.

Embodiment
Below in conjunction with accompanying drawing, by non-limiting citing, preferred embodiment of the present utility model is described further, the utility model provides the aqueous vapor adjusting device that a heavy metal species willow absorbs, for column structure, comprise absorbent core 1 and fixing protective layer 2 and tank 3, it is characterized in that: absorbent core is in fixing protective layer, the horizontal arrangement of each absorbent core, the space of 2-4cm is left between the absorbent core heart arranged in parallel, different absorbent core is staggeredly placed, form vapor channel 4, boundary layer 8 is formed between the absorbent core of different layers, the one end of the column structure that absorbent core and fixing protective layer are formed is fixed in tank water 10 and forms cultivation post 5, cultivation post is positioned in heavy-metal contaminated soil stirring pool 6, stirring pool is furnished with self priming pump 9, sewage containing heavy metal is watered to form the circulatory system downwards above cultivation post, poplar-branch 7 cuttage is in absorbent core, on point, in, lower three layers, every layer of 4-5 direction is evenly distributed.
Described absorbent core Adsorption of Heavy Metals, absorbent core material comprises clay, perlite, weeds, willow fallen leaves, maize straw, and absorbent core composition is good with two or more material, and weed density controls at 60-100kg.m-3, and other material is determined according to actual conditions.
The permutation and combination of described absorbent core: permutation and combination is with ventilation, water conservation for principle, and horizontal arrangement, leave the space of 2-4cm between the absorbent core heart arranged in parallel, different absorbent core is staggeredly placed.
Fixing protective layer can use outsourcing plastics wire netting, height 1.5-1.8m, diameter 1.2-1.5m, tank height 0.2-0.3m, diameter 1.5-1.8m.
