Description
Technical field
The invention belongs to environment remediation technical field, relate to a kind of wetland soil artificial ecology restorative procedure.
Background technology
Along with accelerating development and the surge of population of industrialization and urbanization, the mankind natural resources is utilized scope and
Degree constantly extends, and the environmental problem such as the environmental pollution that thus causes, Sediment Siltation causes the function of lake and marshland and biology many
Sample is seriously damaged.Building and the protection good ecological environment of lake and marshland is the most very urgent, people also unremitting exert for this
Power.
At present, mainly take to plant the life to this region of the method for emergent aquactic plant group at lake land inland water ecotone selectivity
State environment is repaired, and the method has structure lake and marshland ecosystem structure, biological habitat, enriches bio-diversity,
Purifying water body, the multiple ecological functions such as beautify the environment.But, owing to emergent aquactic plant mostly is perennial aquatic herbaceous plant, have
Growth rapidly, the feature that newly-increased Biomass is big, large area deposition in lake and marshland emergent aquactic plant group annual winter will
Withered once as salvaged harvesting not in time, emergent aquactic plant residuum can accelerate the sediment accumulation rate of lake protection, and its plant residue is corrupt
Water body in lake also can be caused secondary pollution by decomposed substance, has undesirable effect lake ecosystem.Meanwhile, harvesting is salvaged very
Water plant to consume substantial amounts of manpower and materials every year, increase government will certainly be managed and protected expense and financial burden by lake protection.
Therefore, a kind of ecological functions of exploitation are notable, can delay wetland plant sediment accumulation rate, alleviate wetland plant secondary pollution
Hidden danger, the lake protection phytobiocoenose construction method that management maintenance cost is low, safeguard the good ecological functions of lake and marshland and improvement
Environment for human survival just becomes technical problem urgently to be resolved hurrily in wetland construction and protection engineering.
Summary of the invention
It is an object of the invention to provide a kind of wetland soil artificial ecology restorative procedure.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of wetland soil artificial ecology restorative procedure, this restorative procedure comprises the steps:
1) polyamide ion-exchange fibre is joined attapulgite and slow release renovation agent by the weight ratio of 1:2-4:1-1.5
In, obtain homomixture；
2) this homomixture is rolled into shape sheet, in the wetland soil that 25-45cm of nuzzling is deep, through absorption, exchange 30-45
Remove from wetland soil again after it；
Described slow release renovation agent includes the raw material of following weight parts: sodium humate 8.4-9.6 part, metal-chelator 5.2-
5.8 parts, biological carbon 2.5-3.5 part, poly-ferric chloride 12.5-14.5 part, sodium peroxydisulfate 10.2-10.8 part, bentonite 3.5-4.5

600nm。
Described step 2) in, after homomixture is rolled into shape sheet, also comprise the steps: at shape sheet pulverizing
Reason, loads in 15-25 mesh nylon net bag or rustless steel mesh bag, in the wetland soil that 15-25cm of nuzzling is deep, through absorption, exchange 15-
Remove from wetland soil again after 25 days.
When ion-exchange fibre is with electrolyte solution contacts, the ion on fiber can be made selective with the ion in solution
Exchange；It is divided into cation exchange fibre, anion-exchange fibre and amphoteric ion exchange fibre.Additionally, ion exchange fibre
Dimension also has the performances such as the most certain intensity, resistance to chemical attack, has at environmental conservation, resource reclaim regeneration, medicine, chemical industry, metallurgy
Wide application prospect, can be used for Adsorption of Heavy Metals and pigment and specific surface is big, ion-exchange speed fast, easily regenerate；The application
Intermediate ion exchange fiber can commercially be commercially available.
Beneficial effects of the present invention: the present invention, with fiber for matrix Compound Punch rod powder, slow release renovation agent, is applied to wetland
The improvement reparation of soil, restorative procedure is simple, quick, is suitable for industrialized production；By absorption, exchange in removable wetland soil
Contaminated ion, reach repair wetland soil pollute purpose, reduce pollutant in soil animal migration and poison degree.
