Description
Technical field
A kind of method that the present invention relates to quick improvement heavy metal pollution of soil.
Background technology
At present, in order to improve grain yield, come into operation inorganic fertilizer, pesticide in a large number in a lot of farmlands, carries out carrying the same of product
Time but have ignored chemical fertilizer and the pesticide adverse effect to quality, soil compaction, subsoil water and the ecological environment of agricultural product so that soil
Organic matter in earth drastically declines, heavy metal accumulation, destroys original soil ecology balance, soil compaction, water and soil pollution, environment
Deterioration, disruption of ecological balance, agriculture production cost increases and agricultural product quality declines contradiction, thus occurs in that volume increase does not increases
Receive and the vicious cycle of environmental pollution madness such as (grow) rivers and lakes water baths.
Heavy metal pollution of soil has disguise, chronicity and irreversibility, and the pollutant holdup time in soil is long,
Plant or microorganism can not be degraded, and heavy metal pollution does not only result in the reduction of the degeneration of soil, crop yield and quality, and
The life and health of the mankind may be jeopardized by directly contact, food chain.
At present, heavy metal pollution of soil recovery technique is all being carried out widely studied by countries in the world, and its main path has 3
Kind: 1. change heavy metal state, reduce its activity so that it is passivation, depart from food chain, reduce its toxicity；2. utilize ultraproduct to tire out to plant
Thing absorbs the heavy metal in soil；3. by engineering, heavy metal become soluble state, free state, more scrubbed, then receive
Heavy metal in collection leacheate, thus reach reclaim heavy metal and reduce the purpose of heavy metal in soil content.For these three
Approach, its concrete method typically can divide following several measure: engineering reclamation activities, chemical redemption measure, agricultural measures and life
Thing reclamation activities etc., but above-mentioned three kinds of reclamation activitiess put into relatively big, the uniform ideal of effect.
Summary of the invention
The problem existed for above-mentioned prior art, the invention provides the side of a kind of quick improvement heavy metal pollution of soil
Method, uses dung beetle enrichment and maggot to be enriched with, it is provided that a kind of economical rationality be effectively reduced heavy metal in soil total amount, and
Pollution-free and destruction, environment amenable soil remediation method to plan reparation place.
To achieve these goals, the technical solution used in the present invention is:
A kind of method of quick improvement heavy metal pollution of soil, comprises the following steps:
Step (1), at the enclosure wall that is arranged around of heavy-metal contaminated soil, the height of enclosure wall exceeds soil 1m, by unfermentable newly
Fresh fertilizer introduces in heavy-metal contaminated soil, uniform with mixing with soil, uses Caulis et Folium Oryzae to educate worm method cultivation maggot, treats fresh organic
Bear maggot in fertilizer, seal, keep temperature 16 DEG C, make maggot purify the heavy metal of residual in soil, after 15 days, keep temperature 36
DEG C, make maggot pupate；
Step (2), after five days, using plastic foil to rely on the enclosure wall that is arranged around to seal soil, temperature is maintained at 45 DEG C
Above, make the fly larvae pupated the most completely dead；
Step (3), opening plastic foil, use ground discharging worms to raise in cages and grow method cultivation dung beetle, 5-6 month, the pool was mutual at underground Wa Tang
Between distance more than two meters, be provided with worm cage in the pool, it is right that each worm cage puts kind of worm dung beetle 20, and throw in fresh pig simultaneously
Excrement, every 2 ~ 3d feeds intake once, after dung beetle amount reproduction, releases in worm cage；
Step (4), after one month, being cleaned out by the dung beetle in soil, pour water, water surface elevation is higher than upper soll layer
More than 20cm, discharges water after two weeks.
Preferably, in described step (1), fresh fertilizer is chicken manure 50%, pig manure 25%, Glycine max (L.) Merr. 25%.
Preferably, in described step (3), the pool is generally circular in shape, diameter 1100cm, degree of depth 90cm for any of the above-described scheme,
The surrounding on the pool and the end, all surround with stainless (steel) wire, fill up with soil afterwards and tamp, and make on lid lid with nylon wire above, each worm cage
Put kind of worm dung beetle 20 right, and throw in fresh pig manure simultaneously, and keep every 2 ~ 3d to feed intake once.
Any of the above-described scheme preferably, in described step (1), educate the concrete operation method of worm method and be: is cut by Caulis et Folium Oryzae by Caulis et Folium Oryzae
Become the segment of a length of 3-6cm, add water boil 1-2 hour, in embedment grass cave after, the mud of 6-8cm sealing, often on upper cap
It waters once, keeps internal moistening, and after 8-10 days, maggot bears.
Preferably, described grass cave is 80-100cm × 80-100cm to any of the above-described scheme, and the degree of depth is 25-35cm.
The invention has the beneficial effects as follows: use water soaking rinse while cultivate water plant, use simultaneously phytoremediation,
Earthworm bioaccumulation and maggot enrichment, it is provided that a kind of economical rationality be effectively reduced heavy metal in soil total amount, and to intending repairing
Place is pollution-free and destroys, environment amenable soil remediation method.
