Abstract
The invention belongs to the technical field of soil remediation and particularly relates to an organochlorine pesticide contaminated soil remediation agent. The organochlorine pesticide contaminated soil remediation agent is prepared from chitosan, bentonite, green algae, citric acid, shell powder, needle mushroom fungus chaff, corn cobs, rice bran, tea seed shells, walnut shells, areca catechu wood bits, palm wood bits, a composite enzyme preparation and a compound microbial agent. According to the soil remediation agent, under the condition that no other chemical solvent is introduced, the mild enzymes and the microbial agent are adopted to treating soil, no secondary pollution is caused, and action conditions are mild.
Description
Technical field
The invention belongs to technical field of soil remediation, be specifically related to a kind of organochlorine pesticide pollution soil-repairing agent.
Background technology
Organochlorine class is polluted, and mainly organic chlorine agriculture chemicals pollutes, and organic chlorine agriculture chemicals pollutes the environment being well recognized as
Priority pollutants, is also typical persistent pollutant, has and is difficult to degradability, half volatile, biology
Accumulation and high toxicity, existed for a long time in nature, and be enriched with by food chain, the degraded of a-HCH and Y-HCH
Half-life is 26 years and 42 years respectively.Gamma Hexaochlorocyclohexane and clofenotane are as main insecticide, in 20th century of China
The 60-70 age was once widely used, and western developed country 20 century 70 just has begun to disable organochlorine pesticide,
China also prohibits its production and use in nineteen eighty-three, but owing to usage amount is big, degraded is slowly in the environment,
Holdup time is long so that organochlorine pesticide remains the class organic pollution that recall rate in environment is the highest.
Organochlorine pesticide can be sunk by industrial wastewater and the discharge of sanitary sewage, agricultural runoff, the dry and wet of air
The various approach such as fall, soil erosion enter water body, but are because it and have the characteristic of hydrophobic parent's granule, the most very
Easily adsorbed by the suspended particulate matter in water body such as mineral, bioclast and colloid etc., and finally with emphatically
The physics chemical action such as power sedimentation enter in deposit, are enriched with in water-bed deposit.
Organochlorine pesticide enters environment mainly three kinds of approach: one is that pesticide directly sprays in soil, is used for preventing
Control subterranean pest-insect, go to cut weeds；Two is all kinds of pesticide prevented and treated disease pest and weed and be sprayed on crop, Qi Zhongzhi
I haven't seen you for ages has the pesticide of 56% to fall in the middle of soil；Three is that part pesticide fills the air when spraying and dusting use pesticide
In air, and along with air-flow and wind migrate, spreading to each corner of environment, once someone calculated, and 60
The clofenotane that the North Sea, age Europe settles every year from air is up to 3,000,000 tons more than.The longest for the half-life
Clofenotane, its distribution has almost spread over each corner in the world, in the age that organochlorine uses in a large number, some
Famous river, in the river of Mississippi, the Rhine, Danube etc., clofenotane the most once detected.
Restorative procedure to organochlorine class contaminated soil at present, mainly has following several:
Peripheral doses method, chemical repair method, plant absorption method, plant-microorganism associating system is to organic
The conversion of chloro pesticide, specific as follows:
Peripheral doses method: air injection is mainly used in repairing by nonaqueous phase liquid in situ, and particularly volatility has
The saturated soil of machine thing pollution and subsoil water.The sealed underground water system that biological restoration in the past utilizes often is made
Become oxygen not enough, and bio-inert well provides substantial amounts of oxygen, thus promote biodegradation efficiency.
Chemical repair method
Roy et al. extracts biosurfactant from peel, applies it to the cleaning of Gamma Hexaochlorocyclohexane in soil,
It is the 20 of clear water respectively that biosurfactant solution with 0.5% and 1% removes the efficiency of the Gamma Hexaochlorocyclohexane in soil
Again with 100 times.
Organochlorine pesticide in soil is mainly absorbed by plant absorption method by root system of plant, but plant roots
Being that the intensity absorbing organochlorine pesticide is not built, it is repaired by organochlorine pesticide contaminated soil, mainly depends on
The complexation produced organochlorine pesticide by root exudates and enzyme and degraded etc. act on organochlorine pesticide of degrading.Plant
Thing root system can secrete the nutrient substance such as sugar, alcohol, protein in soil, for microbe survival；Root system of plant is also
The chemical substances such as organic acid can be secreted, thus it is possible to vary the decomposition of the pH-value etc. of soil, beneficially organochlorine pesticide.
Research shows, has flourishing root system, the plant of root hair can promote that rhizosphere microorganism flora is to herbicide, parasite killing
The organic absorption such as agent and degraded.
The plant-microorganism associating system conversion to organochlorine pesticide, the mineralization of plant strengthening rhizosphere and bacterium
Root and had certain relation by raw bacterium, mycorhiza has micro-life as the coalition of fungus Yu plant to the impact of soil
Thing and the double grading of plant, the ad hoc structure of mycorrhizal plants makes the absorption area of root system increase, can reduce plant
And the fluid resistance between soil, promotes that root system is to moisture and the absorption of nutrient and utilization.Secretions from plant roots
Can also stimulate the transformation of antibacterial, form organic carbon at rhizospheric environment, the death of root cells simultaneously also can increase
Soil organic matter, the increase of these organic carbons can stop organochlorine pesticide to shift to subsoil water, it is possible to increases micro-life
The thing mineralization to organochlorine pesticide.There are some researches show, microorganism to the mineralization of atrazine also with soil
Organic carbon constituents is directly related.Additionally, plant is owing to having complicated root system, its huge root surface area
Also in place of being the boarding of microorganism, thus the growth for soil microorganism provides more existence place and environment,
The aerobic transformation enabling rhizospheric environment is normally carried out.
Although above-mentioned phytoremediation technology has many good qualities, but still there is a lot of incomplete place, actual
Having certain limitation in application, as in repair process, the condition such as soil, weather is had necessarily by some plant
Requirement, be easily subject to the restriction of self and extraneous factor.
Above-mentioned to the restorative procedure by organochlorine class contaminated soil, or can not eliminate in soil the most thoroughly
Organochlorine pollutant, or bring new pollutant, or it uses the restriction receiving environmental condition, exists each
Kind of defect, accordingly, it would be desirable to for above-mentioned present situation, grope a kind of remove organochlorine pesticide effective and warmer
Sum do not produce new contaminated soil renovation agent.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides one and control by organochlorine pesticide contaminated soil
Manage the effective and gentle renovation agent the most not bringing new pollution of action condition, this soil-repairing agent combine plant,
