Description
Technical field
The invention belongs to soil technology field, and in particular to a kind of heavy metal-polluted soil degraded side based on biological coupling technology
Method.
Background technology
With industry and the fast development of mining industry, sludge and dirty tank abuse, the random row of sewage leave about so that heavy metal pollution
It is on the rise, great threat is caused to ecological environment and health, heavy metal pollution also results in soil degradation, crops
Poor harvest, and the life security and life and health of the mankind can be influenceed by water and food chain, in recent years, environmental consciousness awakening, for
The improvement of environment is also increasingly paid attention to, and heavy metal-polluted soil is administered and restorative procedure typically has chemical harnessing method, plant to inhale
Receipts technology etc., chemical harnessing technology is that passivator is added into soil, is handed over by absorption, complexing, precipitation, redox and ion
The series reaction such as change, reduce the biological effectiveness and transportable property of heavy metal, reach the content of reduction heavy metal-polluted soil, still
Chemical harnessing narrow application range, treatment cost is high, it is difficult to a wide range of to promote；Therefore it provides a kind for the treatment of cost is low, operation letter
Single, the good in economic efficiency heavy metal-polluted soil biodegrading process based on biological coupling technology is necessary.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and provide that a kind for the treatment of cost is low, simple to operate, economy
The profitable heavy metal-polluted soil biodegrading process based on biological coupling technology.
The technical scheme is that：A kind of heavy metal-polluted soil biodegrading process based on biological coupling technology, it includes following
Step：Step 1）：Level land：Soil is deep ploughed with hook machine, weeds, stone is removed, and soil block is in small, broken bits loose；Step
2）：Fertilising：Farm manure 1000-1500Kg is applied on every mu of soil, or applies phosphate fertilizer 15-25Kg；Step 3）：Grass seeds prepares：Select June
The ripe plant of Juncao more than age, chooses health, no disease and pests harm stalk and is saved to plant, and retaining 2 to 3 bud sections by every section carries out impact cutting
Processing, then puts treated Juncao seedling to recess, clear water immersion 12-24h；Step 4）：Excavate strip groove：Ditch depth
20cm, line-spacing 0.8m, spacing in the rows 0.4m, 4000 plants every mu；Step 5）:Plantation：Treated Juncao seedling is lain in strip groove
It is interior, then carry out artificial earthing, thickness of earth covering is 3-5cm, earthing completes to carry out irrigation to water, irrigate to drench with soil first and be
Standard, plantation the first month was once watered management in the case where not raining every 7 days after irrigating first；Step 6）：After harvesting
Fertilising：A Juncao is often gathered in, every mu is applied fertilizer with 20Kg composite fertilizers, harvested Juncao is used for biomass power generation.
Described farm manure is pig manure or chicken manure.
Described Juncao is after harvesting three times, the heavy metal analysis for carrying out combustible substance after biomass power generation, simultaneously
Also the content of beary metal of soil sample is detected, detection project is Pb, Zn, Cu, Cd respectively.
The present invention has advantages below：The present invention carries out degraded to heavy metal pollution of soil using the method for plantation Juncao and controlled
Reason, Juncao vitality is strong, cold-resistant, waterlogging, adapts to environment, weather, soil extensively, Juncao well developed root system is typically all up 8 to 9
Rice, carries out heavy metal-polluted soil degraded using Juncao and administers, can effectively adsorb the heavy metal of deep subsoil, good degrading effect, and
And Juncao solar conversion efficiency is high, the conversion ratio of solar energy conversion Juncao is 4-7 times of broad leaf tree, in south China Juncao year
Ton/mu of fresh grass 45 can be produced, 15-30 tons/mu of fresh grass can be produced in northern year, biomass power generation is carried out using Juncao, Juncao is burnt
Gaseous effluent and solid residue afterwards is handled so that the heavy metal substance that Juncao absorbs is focused on, Er Qietong
The content of beary metal crossed after measurement burning, it can be determined that the effect of heavy metal-polluted soil degraded, then heavy metal is carried out to soil sample
Measurement, can quickly grasp the effect of soil remediation, after soil remediation reaches effect, also regard in the Juncao of grown on soil
Forage feed cattle and sheep, are also used as cultivating the culture medium of edible and medical fungi, remarkable in economical benefits；The present invention has treatment cost
Low, simple to operate, good in economic efficiency advantage.
