The moisture adjustment device is of a columnar structure and comprises adsorption cores, a fixed protection layer and a water storage tank. The moisture adjustment device is characterized in that the adsorption cores are arranged in the fixed protection layer and are horizontally arrayed; gaps ranging from two centimeters to four centimeters are reserved between the adjacent adsorption cores arrayed in parallel, and different adsorption cores are placed in a staggered mode to form a moisture passage; interface layers are formed between the adsorption cores at different layers; one end of the columnar structure formed by the adsorption cores and the fixed protection layer is fixed in the water storage tank and forms a planting column; the planting column is placed in a heavy metal polluted soil stirring tank, a self sucking pump is arranged in the stirring tank, polluted water containing the heavy metal is poured downwards from the top of the planting column to form a circulating system, aspen branches are arranged in the adsorption cores in a cuttage mode and are divided into an upper layer, a middle layer and a lower layer, and four to five aspen branches are evenly arrayed on each layer.
Description
Technical field
The present invention 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 that bionical object heavy water, controlled atmosphere joint with the contradiction solving willow Metal uptake efficiency and growth with forest soil and plant structure.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.
Summary of the invention
The invention provides the aqueous vapor adjusting device that a heavy metal species willow absorbs, for column structure, comprise absorbent core, fixing protective layer and tank and stirring pool, it is characterized in that: absorbent core is in fixing protective layer, and the horizontal arrangement of each absorbent core, leaves the space of 2-4cm between the absorbent core heart arranged in parallel, different absorbent core is staggeredly placed, form vapor channel, form boundary layer between the absorbent core of adjacent upper and lower different layers, the combination of absorbent core divides single combination and mixed type, mode is divided into Stochastic sum rule, the permutations and combinations of absorbent core: 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, one lower 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 downwards to form the circulatory system from cultivation post upper end, poplar-branch cuttage is in different 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
Advantage of the present invention: material easily obtains; Installation cost is low; Auto-control; Bio-diversity is protected; Take into account efficiency, 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.
