Abstract
Combine the method for repairing the high soil containing greasy dirt the present invention provides a kind of antimicrobial plant.It is broadly divided into two parts of microorganism remediation stage and phytoremediation stage, wherein the microorganism remediation stage breeds microorganism raised growth by the addition of nutriment, the activity and metabolic efficiency of microorganism are enhanced, while has also done certain preparation for the phytoremediation stage；And the phytoremediation stage, repaired by sowing three kinds of jasmine, chrysanthemum, clover plants, the microorganism biological activity of root system of plant is stronger, has certain consumption metabolism to petroleum hydrocarbon.The index of each side of soil containing greasy dirt after reparation is improved, and oil content is decreased obviously.Easy to operate, good degrading effect of the invention, cost are low.
Description
Technical field
The present invention relates to oil-polluted soils recovery technique field, and in particular to a kind of antimicrobial plant joint is repaired height and contained
The fast method of greasy dirt soil.
Background technology
With China's expanding economy, environmental pollution getting worse.Result from oil exploration, exploitation, processing and accumulating
During pollutant 90% will return and soil, i.e. soil is the final receptor of most petroleum hydrocarbon class pollutants, and native
Earth pollution is referred to as " invisible pollution ".The production and living of soil and the mankind are closely bound up, and high soil containing greasy dirt have impact on soil
Original physicochemical property, endangers human health, threatens agricultural crops existence.China's oil plant produces soil containing greasy dirt about 106 every year
Ton, since petroleum components are complex, natural degradation time length, toxic organic compound volatilization is diffused into air.
The patent of invention of Application No. 201610018597.1 discloses a kind of biological renovation method of oil-polluted soils.
The restorative procedure, in a short time can be by oil-polluted soils using microorganism remediation and agricultural crops combined remediation technology system
Relatively low concentration is reduced to, and processing cost is relatively low, there is certain actual application value.But additional liquid mixed microorganism
Pharmaceutical practice is complicated and workload is larger.
The patent of invention of Application No. 201510727313.1 discloses a kind of biological renovation method of oil-polluted soils.
This method includes four repairing phases.Each stage adds different biomass oil degradation bacterias into soil containing greasy dirt respectively.
This method can also be used for showering available for in-situ immobilization, and repairing effect is good, and repair time is short, method is simple, cost is low.But
It is that additional strain is excessive, the growth conditions for being conducive to all microorganisms is difficult to control.
The patent of invention of Application No. 201410021333.2 disclose a kind of biological agent for soil remediation and its
Preparation method, purposes, soil remediation method.For the biological agent of soil remediation, including by Nocard's bacillus, lactic acid bacteria, gemma
The microbial composite of bacillus composition, and absorption carrier.The biological agent can wake up the indigenous microorganism in original soil, perfect soil
The biotic population of earth, reduces soil pH, improves gas permeability and gas porosity in soil, enables the indices of original soil after reparation
Improve.But said preparation cost is higher, repair time is longer, and practicality is not strong.
The content of the invention
The deficiencies in the prior art are directed to, combining reparation height object of the present invention is to provide a kind of antimicrobial plant contains
The method of greasy dirt soil, both can be used for in-situ immobilization and can also be used for showering, easy to operate, good degrading effect, and cost is low.
To achieve these goals, present invention employs following technical scheme：
(1) height soil containing greasy dirt is turned over, grinds bulk containing greasy dirt soil.
(2) it is 5% modifying agent to be added in high soil containing greasy dirt and account for soil percentage, the modifying agent be by sawdust, chicken manure,
Activated sludge is mixed according to 1: 1: 1 ratio, and adds starch, urea and potassium dihydrogen phosphate, makes C: N: the P 120 in soil:
10∶1.So as to microorganism obtain in the soil nutrition and can raised growth, further enhancing activity and the generation of microorganism
Thank to efficiency, the microorganism remediation stage is possessed than advantageous condition.
(3) soil is turned over every 3-5 days, fully aeration；Watering, keeps soil moisture 20% or so.
(4) high soil containing greasy dirt is treated because rotten hot and continuous high temperature one month, after micro organism quantity reaches maximum, in high oil-containing
Vegetable seeds is sowed in dirty soil.Phytoremediation is proceeded by, plants plant as jasmine, chrysanthemum, clover, the density planted
For：2500~5000 plants/acre.
Embodiment
The first step：Height soil containing greasy dirt such as is turned at the simple process, grinds the native containing greasy dirt of larger particles.
Second step：Added in height soil containing greasy dirt account for soil percentage be 5% by sawdust, chicken manure, activated sludge by
The modifying agent mixed according to 1: 1: 1 ratio, and starch, urea and potassium dihydrogen phosphate are added, as C sources, N sources and P sources, make
C: N: P 120: 10: 1 in soil.Once turned over every 3-5 days, soil is fully aerated；Watering, keeps soil wet
Degree is 20% or so.
3rd step：The microorganism rotten hot phase terminates after one month, proceeds by phytoremediation.Jasmine is sowed into high soil containing greasy dirt
Jasmine, chrysanthemum, clover seed, and make its planting density be 2500~5000 plants/acre.
Claims (6)
